I apologize for the terrible background noise, as this was taken when Mr. Takumi Kurosawa was available (in the restaurant). Ideally, we would have filmed it in a studio. I will make sure that we create an improved version when I am back in Japan again and have a chance to visit Takumi-san.
Don't worry about the noise; it only makes your presentation more honest and not self-promotional. Greatly honored to hear you may visit the USA. Salutes and welcome!
My daily driver is a 1985 Toyota pickup. When it was new, I changed it every 3000. For the past decade I have changed it every 5000 miles. I change the filter every time. It’s hard to argue with success. I have about 300,000 miles on the stock 22RE engine. I do it myself for about $45.
@@miriamvivo4279 My Subaru Legacy 1992 ─ still run/driven until it was stolen last month. Japan Made - in some bad odd/Apple mostly can be driven many years with simple Oil Changes.

@@Bobbyleejoe2556 Yeap! Well - they are making changes as of late that are questionable - just looking at what happened with the tacoma wastegate issues on the turbos.... Other than that I would be all over a toyota/lexus product for a daily!
Yeah - unfortunately that’s true. The only cars we lease are my wife’s daily drivers (currently a 2022 2.0T Sport Accord), but being gear heads will still do oil services every 5K. We’re crazy about car maintenance, so many times a friend or family member will buy out our leased cars at the end!
@@Odat When you realize how much a gallon of oil is expected to do inside an engine, you realize that replacing it before it begins to get dirty or diluted is so important. Especially if you have a DGI fuel system.
I agree 100%. I used to work in an automotive machine shop, it's sad to see how many crud filled engines would come in. It's cost very little to change your oil yourself.
This ^^. When I asked about the longer intervals between oil changes, my mechanic showed me the sludge filled top ends of a couple of Audis he was repairing. Both had under 100k miles. I’ve always done 3k oil changes. It’s like going to the doctor, preventative maintenance is cheaper in the long run.
This is what happens when you use a one size fits all approach. I had to get this straight as 5000 miles (conventional) usually lasted me 18 months and the oil was horrible smelling. The oil cap had a thick crusty layer on it. Never listen to someone trying to sell you a new car. They'll say it's 40000 mile oil. "Real high tech stuff son". 3000-4000 works for me or 2 years tops. If I just drove highway I'd still have to check the level. Also, oil should never be like black paint.
@@marshmower On a Subaru, one can change Oil & Filter in less than 20m so I do 3 times a year ─ from a big container of 20 Gallon with Pumps. Cost us about 20-35 Dollars annually and The Engine runs smooth like a 5-year old 1992 Subaru Legacy Model LS. And I washed Air Filter then alternate two of them until I bought new one.

You do not need to change your oil every 3000 miles,total bs. Just change your oil and the filter every 5000 miles ,and your engine will last for a long time,but you must do it every 5000 miles.And every time you change your oil change your oil filer,it is not a good idea to change it every other oil change,do it every time ,oil filers are cheap.
I was a Tech for Ford in the 80's...we had Ford engineers come into the dealership to train us periodically. One session was on engine maintenance and covered oil changes. The engineer told us - "Forget mileage and time intervals. Different cars in different environments will tax their oil at different rates depending on the circumstances. You change the oil when it needs to be changed - that could be in a year - it could be in 3 months. Pull the stick, look at it, and check the color. And absolutely change the filter every time." He told us a story about an old guy who had an old Ford car and every month - every month - he took the car to the dealership and had the oil changed. When he finally traded it in, it had many years and many miles on it. Because of the unique circumstances involving the car, Ford had the car brought in and the motor disassembled for analysis. He said despite the years and mileage, the engine was pristine. Today's cars have a unique interplay in the engine with lubrication. It pays to change the oil as needed - not when "recommended."
😂 this comes from a company who’s name stands for; “Found On Road Dead” 🤣 Oil color doesn’t mean jack squat. It darkens literally instantly from the FIRST heat cycle of the engine. 🤦🏻♂️ You don’t need to change your oil every month to have a Pristine Engine. 🤦🏻♂️🤨😤😑
@@spinnetti - you really can’t go very long on the oil with todays highs stress engines. Besides, most “synthetic oil” sold on American store shelves are a Group lll highly processed regular conventional oil and not 100% Lab Made Synthetic, so you can’t really go long on it, regardless of what they tell you. 👍🏼
This seals the debate for me and closes the chapter once and for all. I cannot thank you enough, David. This was so enlightening and educational at the same time on so many levels. I will be following through on your advice.
Yep. This is great. As a part of his reasoning, would it be helpful to consider the average amount of miles driven per year in Japan (5,000-10,000 kilometers = 3,000-6,000 miles) vs USA (10,000-15,000 miles = 16,000-24,000 kilometers)? Approximate conversion 5,000 kilometers = apprx 3,000 miles. I would think that this drives the point of changing 2 times per year (winter run and summer run). I have personally averaged 10,000-13,000 miles per year. I also consider engine hours of run time and keep an eye for 150-250 engine hours per oil/ filter change. I have tried to stick with 5,000-7,000 mile/ 6 month oil/ filter change intervals. This does make me want to consider going to 3 times per year/ 3,500-4,500 miles. I have done 5,000 mile oil changes every 6 months and only change the oil filter 1 time per year and results were good with oil analysis.
@@sloanclick It greatly depends on driving style, but I always change mine in spring and fall, regardless. Winters here are hard, and I’m sure very hard on engines. You generally have more idle time, plus all the cold starts. Full synthetic oil has made cold starts much better than conventional oil did in the past, but it still puts extra wear and tear on all your moving parts.
@@stendecstretcher5678 What is the oil viscosity in your Corolla/year of Corolla? The new ones use some type of oil I never heard of or see much: 0W-8 and or 0W-16????
Another factor is time. If you have sports cars that don’t see a lot of miles per year, you still want to change oil annually even if you’ve only driven 1-2K miles in that time.
As a DIY car owner for the past 50+ years, a very important issue is New car oil changes. On a New car, after the 1st 1200 miles or so, I always change the oil & filter to remove any break-in oil and metal particles, during the break-in period. After that, I go with the 3k-4k oil and filter changes. I've Never had an oil related engine problem(30+ cars). My last car, a 1995 Lexus SC300 had over 203k miles and ran like new, when I sold it. (after 20+ year ownership).
The higher priced synthetic oils generally have a higher “Total Base Number” (TBN). The TBN is the component that neutralizes the acids built up in the engine. They also have a higher detergent package which keeps contaminants suspended in the oil until they can be filtered out. This is especially important for diesel engines.
@@Painting_Inspiration Well I have used AMSOIL products but not exclusively. Currently I am using MOBILE 1 0w-20 ESP X2 for my 2023 GMC SIERRA SLT with the LZ0 3 liter diesel along with an AC DELCO PF 66 oil filter.
@@NMTRUCKER I agree with you that the type of oil makes a difference. I not as much as Frequency. I have a daily driver 2002 GMC Envoy. It has 342k miles. I have done 95% of my oil changes. I use a good quality oil. Changed every 7k to 10k miles. The reason I can go that long. Is because it has a extra deep oil pan. It holds 7 quarts of oil and it's a straight inline 6 cylinder.
@@NMTRUCKER Well, I can't agree to your oil wisdom since you are using 0W20 oil. I switched after 3,000 miles to 5W30 Full Synthetic because of the heat of the turbocharger, considered 'Severe Service'.
Depends on your driving style and types of miles. Highway, city, long trips vs short. I think 3k is a good interval for japan bc its a smaller country with a more urbanized layout. For the US in more spread out areas i don't see any issue with a 5k interval.
@@tomr1107 We understand that some live in a Condo/Apartment Building the changes of Oils on his own would be hard. All Guys who race at the Tracks changed oils after their races and the Friends I knew then was not an Engineer - just a shop Welder Worker knew and did take out the Engine from his race car and Reset the Pistons Rings and of Course New Oil pumped in when the Engine was reinstalled ─ the Shop/ Office that we worked then is a Drilling Services Company ─ so they have all the Tools to haul out Heavy Engines or Oil Tools.

I do @ 5,000 miles. Twice a year for my F150 which gets under 10K miles per year (Mobil 1) and about 5,000 for a Toyota IM which isn’t 5 years old yet but just passed 155K miles. 3,000 miles would be close to monthly.
I change my oil every 5,000 KM as per Lexus’ recommendation. He’s speaking facts though. 2 of my relatives are at 500,000 and 750,000 KM on their LX and Land Cruiser respectively and they change every 5K km.
Change oil every 6 months regardless of mileage driven. I drive my 2005 Camry with well north of 350,000 kms. Almost 19 years old & runs like a clock. Take my car twice a year to Toyota - March & September. Toronto, Canada
I own a 1993.5 Infiniti G20 with 271,000 miles on it. I have changed the oil every 3k miles since it was new. I recently dropped the oil pan to inspect it expecting to find some sludge, remarkably it was very clean. Also the engine runs great to this day.😊
@@jimlewis2395 If you drive 3,000 miles city and lets say drive it less than 10 miles a day and the engine won't find itself in operating temp, and oil changed lets say once a year, its possible to build sludge on that.
I can attest to this method i have an 2008 Infiniti G37s and change my oil every 3000 miles and im currently at 285k and it still running as smooth as when i first got this car at 25k no sludge leaks. I daily drive my car,yes oil burning is common on these cars so i always check oil level once a week to top off if needed. hopefully may car can last more than 300k+ miles .😊
I usually get between 200,000 miles to 300,000 miles out of a car. I have followed changing the oil every 6000 miles as mfg recommended. I have never had an engine related breakdown due to oil. (belts break, idler pulleys, starters, alternators, freeze plugs etc). I live in a northern climate where salt is heavily used on the roads and the main issue is corrosion from salt.
I purchased my first car about 25 years ago and at that time the recommended oil change frequency was 3000 miles which I followed religiously and that car lasted me 12 years with little to no problems. Since then I’ve noticed manufacturers keep extending the interval from 3k to 5k to now 7k. However I always still change my oil about 4-5k miles based on my experience with my first car.
@@jimlewis2395 This is not only because of longer intervals. Cars today are in general designed to be less reliable and overcomplicated. My first brand new car is now 15 years old and 250000km, just running fine. Oil change every 10k km from good brand 5W40 API SN.
Several more reasons for those longer reco interval: 1) The reco change frequency factors into “how green” the car is. By having artificially longer intervals, the same car is made to look more green on-paper. 2) Cost to maintain/operate. This is required to show on new car sticker. Same idea as #1, just slightly different reason.
@@cursem "Cars today are in general designed to be less reliable and overcomplicated" In general, an utterly ridiculous and uninformed comment. Some manufacturers build their entire reputation on reliability; Honda, Toyota, Lexus, Mazda. Some used to have a reputation for reliability but have lost it due to using cheap or plastic components that do not last; Mercedes, Audi, VW, BMW. Some are just poorly designed from the outset, but they are not designed to be unreliable. My Mazda 2 is 7.5 yrs old and has an O2 sensor replaced out of warranty for free and pair of rear shock absorber end-stops replaced. That's it. Reliability IS designed into the car. Unreliability is not. My first car was 45 years ago. Then if a car lasted 8-10 years it was OK. Now an 8 yr old car with 100,000 miles has got many years ahead of it if properly serviced.
Don't the new Toyota Corolla 2.0 engines use 0-8 and or 0-16 motor oils??????? I have never heard of these as they are not as common as 5W-30 or 10W/30 engine oils.
It's just amazing that Porsche, with the 997 back in 2005, had a 20,000 mile oil & filter change interval. Before that, with the 996, it was 15k miles as if that was not bad enough. Imagine having oil in such an expensive and troublesome engine for so long.
I have a 1986 Nissan D21 4WD pickup with a V6 engine. It only has 210,000 miles on it, which isn’t much per year, but it has lived most of its life at an elevation of 9000 feet. That means cold temperatures in the winter and lots of cold starts. I have religiously changed the oil every 2500-3000 miles and it runs like a dream, is a true work horse, and I can still pull mountain passes in 4th gear. I’ve been a big believer in frequent oil changes for fifty years and my personal experience confirms the wisdom of doing it and now this engineer further validates the practice.
I have 2-71 Datsun 521 trucks having one for 46 yrs while the other 28yrs. Owners manual recommends oil changes at 2000 miles. I've been changing about 1250 miles including filter. They use no oil and run great after 53 yrs. Total.investment for both is $2300 usd. Never longed for anything else as they are super economical, easy to repair and highly modifiable still to.this day.
Cold starts aren’t that bad if you have 0 weight winter oil. Engines build pressure the moment that it cranks. What does cause a delayed oil pressure build up is not filling your oil filter. Oil geeks did a test, and it took 5 seconds for the engine to build pressure, as opposed to having it filled in which it took half a second.
Even in the manual stated that Urban stop start traffic requires 1/2 interval oil change. Read the manual people. You don’t need expert’s opinions. The manufacturer already put that in the manual.
But never reinforces this fact, untill you go to make a warranty claim But you are correct, city driving, extreme cold conditions, extreme hot conditions, dusty conditions, low grade fuel, towing a big boat or caravan ( RV ) are all severe duty cycle and need half the service interval. So , just simply service the car at half the recommended interval, as the manufacturer is simply wanting to show cheap ownership costs and does not give a fcuk about your cars lifespan. The shorter, the better as far as they are concerned!
This is where I rarely get much agreement from other folks: in my opinion, you should change your own oil, and you should try to perform the oil change where you have plenty of time to let the old oil drain for a couple hours, in order to get every last drop of old sludge out as possible. Sometimes I'll pull my oil plug out, then go mow the lawn or do whatever else needs to be done. I'll come back in 2 or 3 hours and there will still be a slow drip. If you believe the thickest, sludgiest oil is going to take longer to make its way out, then I want to give it plenty of time to make the journey. I want as much old oil out of my truck as I possibly can. And if I have the time and patience to do it, why shouldn't I take my time and let it drip? It can't possibly hurt, and it could possibly help. Maybe 10 minutes is sufficient, but I don't mind waiting.
Also the engine needs to be warmed up to operating temp before you drain it which gets any sludge or contaminants back into suspension so it can be drained all out.
I just replaced my rod bearings and main bearings with the engine still in my truck. Oil was still dripping on my face, on my glasses and in my eyes 2 days after I had the oil pan removed. Also just for kicks (after 3 days of draining) I Shot my air compressor into the send line of my oil cooler and about 4 ounces of oil still came out of the return line. Expect about a half a quart of oil to still be in the engine and cooler lines no matter how long you let it drain or drip.
My car has 5.4 litres of oil in, but only ~4.7 comes out when changing the oil and filter. The rest is still in the engine. This means there's little point in getting every last drop (you won't!) but your approach of going away to do something else is a much better use of time than standing there watching it 👍
I sometimes went up to 10k miles and often 7k miles but regularly 5k miles on my Toyota Camry. Changed the trans fluid every 60k-80k and it went up to 400k engine and trans. Today I sold it to a family member and it’s still running. Same engine and trans 😊
If oil is synthetic, as long as it's clean, you don't have to change it. After 7,500 miles, the oil will be breaking down just a little, but 10,000 miles would be fine as long as it's checked often and remains clean.
My son’s goal is to graduate with a Mechanical Engineering degree (he is currently in the 10th Grade in High School), move to Japan, and design vehicles for either Toyota or Honda. The Nissan GTR is his dream car. I wish he could meet you two gentlemen.
@@thedon9670 I work for an engineering and manufacturing defense/NASA contractor. A mechanical engineering degree is extremely good and will be for decades to come. The EVs are not succeeding and will not succeed. Take a look at the inventory at dealerships.
It’s good to know you can switch from a viscosity to another from season to season. I will put 0w20 into my odyssey for winter and 5w30 for summer here in Toronto. Thanks
@@Americafirst-i8q second that. If engine does not call for 0-20, it means it needs a thicker oil when cold (larger tolerances) or vise versa. Specified oil viscosity is part of engine design.
No need to do that. I took two Odysseys from new to near the 200,000 mile mark and sold both of them still running like new without ever feeling the need to change viscosity from the factory recommendation--living in a northern climate with harsh winter. Removed valve covers and engine was squeaky clean at 180,000. Always followed the recommended viscosity for each and always changed the oil and filter on time. Fortunately, the maintenance minder on Odysseys fluctuates between 6,500-7,500 miles so that helped as well.
It really depends on the engine as well. Our Camry has about 250K miles and is still reliable. On average, we've been changing oil and filter every 5-6K miles.
My coworker has a 2005 Camry 4 cylinder with 402,000 miles, says it's still as reliable as day 1. Toyota engines are some of the best. Transmissions as well.
Good info but what are the suggested time intervals for low mileage cars? My wife only puts about 4,000 a year on her Prius but I still change it every 6-months…once it only had 1,300 miles since last change.
Absolutely spot on. I have had numerous vehicles since 1969 (1 222 879km - 763K miles, in 53 years so far) and have always changed my oil as prescribed with the cheapest non synthetic every 5000 Km (+- 3125miles) and never had a problem. Just two examples : Peugeot 404 sold after 300,000Km and a 1.2 litre Toyota Corolla station wagon which had a 4 speed box and a lower range differential than the sedan, making it rev at about 5500 rpm at 120kph which I sold after 46 years and 350 000 km and incidentally cost me 34cents per km (maintenance + purchase price+ petrol +insurance) for the duration I had it . I think a contributing contaminant to any engine degradation is the ingress of petrol into the oil, necessitating in more frequent oil changes than prescribed.
I’m ok…with regular oil…cause your changing it so often…synthetic gotten really cheap at Walmart…so I use synthetic…I will say 0/40 synthetic in the winter time is really nice…
Some of my cars got old with huge mileage...500,000 or more. I would change the oil once in a blue moon. Maybe every 15,000 - 20,000 miles, even longer. Cars had no book value, I had nothing to lose. I hoped they would die so I could get something new. But, they kept on running. What cars are these? RWD Volvos, models 240, 740 and 940. Reliable and dependable even when neglected. Take that new car makers... You and your aluminum block engines with plastic manifolds... No amount of oil changes will fix cheap disposable engine.
I change my oil and filter every 3000 miles. When I bought my new 1992 chevy silverado shortbed truck with a 350 V8, I changed the oil at 500 miles to get rid of any tiny metal splinters that many have ended up in the oil, then every 3000 miles. I still have the truck, it's still in perfect condition, no accidents and no work on the motor, it still runs great with 40 pounds of oil pressure and 180,000 miles. I get asked by strangers regularly if I want to sell my truck. The answer is always no, and always will be. Funny story, I had to replace my air conditioning system recently and the guy I brought it to argued with me when I said, well, I guess after almost 30 years of service, it's due. The mechanic said, no, it's not the original air conditioning system. I said, yes, it is, I said, I should know, I bought the truck new. He was floored, he couldn't believe that the air conditioner lasted almost 30 years without any service being done to it. He said, that's just unheard of. I had him replace everything with original parts and he did a great job.
My first vehicle was a ‘99 Silverado 5.3L Vortec. I bought it with 250k miles from the manager of a dealership who used it to tow his boat and took very good care of it. I changed the oil every 3k miles and never had to do any engine work on it. I eventually destroyed the rear end (user error) and retired the truck at 500k miles. Change your oil frequently.
To me it still depends on your driving habits. Mostly long trips extends the useable range to 6, 7, 8000 m I less or more. Turbo shortens it due to the heat when the oil passes through the turbo unit. I drove a Ford Duratech 275,000 miles on a10,000 mile synthetic schedule and it was fine.
@Digital Camaraderie nearly all brands can do that with proper care. I get 300,000 miles out of Fords and Chevys as well as Japanese cars. Only difference is the Japs are a bit more reliable.
It basically depends on your driving conditions and the varmint you're driving in. Sometimes you go as little as 3000 and you can be up a little bit above 5000. I actually change my oil so much that I change the oil filter every other oil change. And change my tranny oil every 10 to 12 thousand miles. I worked at one shop with a never change rear end oil. They have the 90 weight bucket there since the shop open once I talk to the owner about getting the 90 weight change and all these customers cars we sold a lot of 90 weight gear oil. Even gives the vehicles a little bit better gas mileage with fresh gear oil.
What's never talked about is the timing of your oil changes. It's now so much the high Temps of summer that matter as much as the lows at night. Because cold starts are affected by the night Temps. So when summer ends consider changing to a thinner oil when night lows get below 40 degrees at night. Adversely, change to a thicker oil in spring when night Temps consistently remain above 40 degrees at night. Hopefully my advice will now save the human race!
I change my oil and filter twice a year, regardless of mileage (that comes down to about every 6.000km) My 15 year old Mazda 6 seems to like it, as it has been bulletproof since I bought it new!
In short: Every 5,000 miles or every 6 months when using synthetic oil and a decent oil filter when mixed with city and highway miles. In certain cases: Every 7,500 or every 9 months given that the car can display oil life % and I have experienced that the oil life goes to 5% after driving for 6,500 miles; or the oil life goes to 5% after 9-12 months of low mileage driving.
Mr. Kurosawa should know. "'Engine oil" is not oil in the traditional sense at all. Crude for example is just that. Not refined. Engineers over a 100 years ago realized that dumping crude into a crankcase guaranteed engine failure. Chemical refining and changing the physical molecular compounds were the key to the lock in providing a lower frictional coefficient between dynamic moving parts in an engine. Examining "Primitive"' diesel engines that still run today, use high pressure and lower thermal burdens to the lubrication system. The volatility of fuels has a major impact on the viscosity and lubricity of the oil. Remember Castrol commercials back in the day, Protects against thermal breakdown. Marketing jargon, with chemical engineering behind it. Why do F1 teams basically rebuild the engine after one race? They use shitty oil? not likely. Mr. Kurosawa mentioned a salient point: Contaminants. Where do contaminants come from and what are they? Free radicals from the metallurgic reactions between unlike substances as they are oxidized. If you drive 500 miles day you should replace the lubrication every day. Huh? It has been measured that when the typical oil change is performed only 78% of the volume is collected. The remainder is left to recirculate and cross contaminate the new lubricant. Why do "Oil' companies add zinc and organic materials? They are designed to bind with microspheres in suspension. If you are able, you should rebuild your engine in an anaerobic vacuum every time you change your "Oil".
My 2005 Chevy Trailblazer has had the oil and filter changed every 6000 miles I use Valvoline Full Synthetic. My engine runs as quietly at 175000 miles as it did when new and doesn't burn or leak any oil.
I’m the guy who does double oil Changes .. makes sure I get the oil cooler and everything out or else 15-20% of the oil in the engine remains for another whole change. I use the fake synthetic group 3 oils on sale for the flush.. then amsoil or redline. 5k miles max usually 3500 or so
It appears my instincts were correct. Got sick of being ripped off for basic service so I decided to learn basic mechanics and do many jobs myself; oil, filters, brakes, et al. Oil change every 5-6,000 km with good quality oil. Thanks for this.
According to many oil analysis, oil+ filter change all 10 000km (or 1x per year) with full synthetic oil is ennough (insteed of 20000 to 30000km "recommended from the car brands!!!) change more often is oil waste ...on ALL modern engines, you have no choice for another oil type that the recommanded one , example for the Ford ecoboost 5w20 WSS-M2C948-B and not another, using oil without the right specifications did voids garantee in many cars brands!
You don't buy a car like the GT-R to be a cheap ass. Change the oil every 3k not 4, Mobil one or equivalent. Mine has 123k on it. Compression test, is as good as it ever was. Mine is built and Dyno tested to 1050hp. Do the right thing. Change the oil at 3k.
I use Castrol Edge 0 - W 40 in my 2018 Challenger R/T Scatpack and change oil and filter when my oil gauge tells me I’m at or about 10% life expectancy as recommended by Dodge. 😎 I liked the fact that you mentioned Castrol as well even though they’re not sponsoring you. Well done video gentlemen! 😄
Very informative and useful content. Thank you however u have forgotten to specify the time duration if the car is less driven which can clock the 3000miles /( for how many years of duration)? So 3000 miles or how many years? Per oil change
I bought a new 2002 Tacoma V-6 Prerunner and I've changed the oil and filter every 5K miles and it is still going strong with 310K miles. It does not use any oil between changes. I never used synthetic, just regular old Valvoline 5W30. People say "use synthetic so you can go 10-15 K miles between changes"...no thanks. Synthetic is just as black and full of crud after 5K miles as regular oil. It's the dirt in the oil that grinds down the internal parts until the tolerances are gone and you start burning oil.
yes it may be just as black, but a good synthetic oil like Amsoil signature hold the particles in suspension so the oil can still do it's job. But of course you can use whatever you want and think what you want.
I disagree. I researched synthetics back in the 1990's and switched over to them on both cars and motorcycle. I live in the Detroit, MI, suburbs. In 2003, facing a longer commute due to my office being moved, I bought a new Honda Accord. After breaking it in with conventional oils for the first 11,000 miles, I switched to an annual synthetic oil change using Amsoil synthetic oils. For the next 12 years, I put on substantial amounts of miles commuting to and from work and several substantial road trips. One year exceeded 20,000 miles, but the average mileage for that 12 year period was over 15,000 per year. In 2014, I bought another Accord and the 2003 became the 'kids car'. Usage profile was now driving to college and residing in Kalamazoo, MI, a two hour drive from Detroit. Mileage numbers on average decreased substantially as now the car was being used mostly to drive just a couple of miles at a time to get to class or work or other activity. The number of miles per trip decreased which actually is more challenging to engine oil than a 60 mile daily commute where your engine reaches full operating temperature and can boil off any water (condensation). Kids moved on, they no longer needed the car, so it now it's my 'dog car'. Driven daily to where I can walk the dog off the leash, about 12 miles per day. At 257,000 miles, this car still starts the same way it did when I picked it up new at the dealer. My mechanic, who specializes in Japanese cars, has never indicated that any type of valve timing is necessary, as there is no valve noise coming off of the the top end. I still track gas consumption via spreadsheet and I see now that I get an average of 28 mpg as opposed to 33 mpg when most of the mileage was highway. Now averaging about 7,000 miles per year for the last five years. my annual oil consumption is less than 3/4 quarters quart per year. (yes, I'm very geeky at recording all of this). Back in the 1980's, I took a course at the New York New School on maintaining your car. They called for 3,000 mile oil changes and I followed it diligently for over a coupe of decades. In 1996, my VW Jetta, with 90,000 something miles blew it's head gasket. The mechanic rebuilding the engine remarked that the original bore marks from the cylinder walls will still very apparent, despite usually being worn off by 40,000 or so miles. He attributed this to my dedicated oil changes at every 3,000 miles. So I do agree with the premise here that frequent oil changes are vital to long engine life. But synthetic oils changed the game here in terms of how long an oil can last. Note we would not have our current aviation industry without synthetic oils as commercial jet engines would not run with conventional petro based oils as the service demands are too high. Synthetic oils simply withstand the temperature requirements needed in high performance engines so much better, along with slower oxidation and degradation. So bring all that in to a mild mannered auto engine such as a Honda Accord and you're easily good for a year and 20,000 miles of highway driving or 10,000 miles of short distance driving. Economics here, I used to be able to point out significant savings when I was commuting. Since I don't drive as much since I've retired, current costs bring my once a year oil change to parity with the local oil change shops. I do my own oil changes. so all I pay for is the oil and filter. That's getting close to $100 per year per car. Local garages advertise specials close to $50 for a regular petro based oil change, and I'd need to do that twice a year if I adhered to a 3,000 mile oil change. But so far, I find great satisfaction in doing in my own oil changes. I know everything is being done right, I inspect my engine to see if there are any other indications of oil leaks or other problems, and I'm content with the fact that my engine is bathed full of the highest quality oil. Finally, I always change my oil filter with each oil change. (Why take a shower and not put on clean underwear?). But I don't change my engine air filter if it has less than 5,000 miles on it. Hope this helps. Happy to answer any questions you might have.
I use Royal purple high mileage with robust zinc and I use Lucas high mileage with a k&n filter. I change my oil every 3-4,000 miles and underneath my valve covers of every vehicle I’ve owned still looks like new with barely any wear. I work at a parts store and our commercial vehicles have had their oil change every 10,000 miles and they burn a little oil and also have lifter noise until it warms up. You can’t tell me the oil and oil stabilizer I use does not work. “Lubricant is the life of your engine or transmission”
It is an honor to meet your friend David. What an amazing car the Nissan GT-R is. My absolute favorite car as is the Lexus GX460 which I am purchasing very soon. What a great video and the oil change advice is worth its weight in gold! Love Castrol and used it for many years! Thank you!
I disagree with the Lexus service recommendations that state to change the oil & filter every year or 10,000 miles, whichever comes first. Ridiculous, I have already changed my oil at 1,000 miles on my new 2023 Lexus ES300h Ultra Luxury. And, I shall be changing it every 5,000 miles thereafter using Liqui Moly Special Tec AA 0W-16 and a Toyota oil filter 90915-YZZN1. Like Scotty Kilmer and The Car Care Nut recommend on YT, change your oil & filter regularly (six-months or 5,000 miles, whichever comes first under normal driving conditions) because oil & filters are cheap, engines are expensive.
This is interesting. I asked this question to a number of mechanics and they said you can do it every 5000 miles. I kept my last car doing this for 200,000 miles with absolutely no problems. It was a 2006 Saab 9-3. Now the second owner following that schedule has 254,000 on the engine, still changing it every 5000 miles. The trick is to use synthetic oil with the turbo engines so the oil will hold up. The oil is a little more expensive than the oil they are suggesting but you can keep your car running for 250,000 miles easy with 5000 miles per oil change. Then again, the USA is far more spread out than Japan so doing longer trips instead of shorter ones lengthens oil life as well.
@@CadillacDriver Actually, we do. My brother owned the same car, with less frequent oil changes - following the oil life monitor he changed it every 9000 to 10000 miles. The motor gave out at 150,000. So he lost at least 100,000 miles of engine life following that longer interval. Do it at your own risk.
@@Buc_Stops_Here yeah but - again - even if your story is true about your bro having the same car (which I believe to be fabricated, or you would have put that in your OP as a point of reference) you still DON'T know. One identical model of car can last a lot longer than the next. It's not an absolute science.
@@CadillacDriver Just call this number and ask for George. He is a mechanic who works on Saabs. he will tell you the same thing I did. I am sure you don't believe mechanics either do you? Autotech, Danbury, CT. What evidence you have that cars that get oil changes far part last just as long? I bet no reliable mechanic will back up your statement.
I have always wondered about this. As a European, it's very surprising you can actually find non-synthetic oil to buy. In Europe mineral oil is reserved only for classic cars and you typically have to order it in a specialist shop. Even semi-synthetic oil is a rare thing to see, let alone recommended for use in a modern car. I've not seen semi-synthetic oil as a manufacturer recommendation since the '80s. Fully synthetic became the norm in aftermarket also, in the '90s. At the same time I've always wondered why outside of Europe people talk about 3000 mile oil change intervals when here the normal interval would be around 10k. Can someone tell me if the oils and recommendations really are different in North America, for example?
Meh. Use pure synthetics and change every 10k. I've been doing that for over 30 years and have run several engines up well over 200k with no issues. Easy to keep track of it too. Just use the odometer as your mileage record and simply change it on the 10s. As for thinner in the winter, thicker in the summer, that's the whole reason multi-viscocity oils were invented; so you didn't have to change it seasonally. 10w30 is actually a 10-weight oil with polymers in it to make it thicken as it heats up and perform like 30-weight.
Thank you for sharing Takumi Kurosawa thoughts about oil changes. I love my vehicles but I don't drive them enough to pass the 3k miles mark a year therefore my personal policy is to change the oil and filter at least once every 11, or 12 months tops.
@@UncleKennysPlace that is excellent advice. It staves off some of the oil dilution by condensation. And since cold engines run rich, a cold engine has some chance of oil dilution with gasoline. An engine with some wear is expected to burn at least a tiny bit of oil. The problem is that the oil level may appear normal but it's been replaced by condensation from combustion, deposits and raw fuel. So what I do is change any brown oil or really sour rubbery smelling oil. Especially conventional! But that product has evolved a little...
I buy the best oil and filters and change every 4000 miles, I always have, and always will. I plan to do the same for the 23 Lexus LX 600 I just bought, cheap insurance on a magnificent and expensive vehicle, I did the same on my 18 LS. Excellent video and interview.
Seems there's some variability that isn't addressed by a 3,000 mile interval. If it's a daily driven commute vehicle all highway, if it's full synthetic oil, etc. The oil will last much longer than if it's driven in stop and go traffic with cheap conventional. If you really want to know how often you need to change, get the oil analyzed at your change interval and you can find out if it's starting to break down or getting high on contaminants. There are Toyota engines that have gone over 1,000,000 miles with nothing but 10,000 mile change intervals.
If you don't drive you vehicle very much 5K per year, should i change oil at 3K or is there time frame (every six months) for a vehicle that isn't driven as often?
Personally I would change it Only once a Year in your case just before winter, Unless you drive it Really hard meaning flooring it every where you go, Because it does make a difference in How you drive, In your case the Best thing for your Vehicle is driving it at say 75 mph for say 20 to 30 miles once a month would be very beneficial because it boils any moisture out of the engine when you do this and burns carbon off of the Valve etc, I would also run only top tier Gasoline if that's all you drive.
I change it twice a year due to weather change. Once in spring time and once before winter. That way, you are not having to do it in the cold if you change oil yourself.
Hey if I used a synthetic oil. Do I have to change every 3,000 miles? Maybe if you using a regular oil you change every 3,000 miles but not synthetic oil it's too expensive. Plus future vehicles are electric no more oil change etc.
Very good advice. My 2010 Rav4 (4 Cylinder) was serviced at a toyota dealer every 8000 KM (5000 Miles), the engine lasted only 200,000 Km(about 120000 Miles) before it started giving me trouble. I traded the Rav4 after 13 yrs. Was expecting the engine to last at least 300,000 km.
@@StubProductions I was thinking the same thing. I have a 2007 Corolla and oil is changed every 5k miles. My corolla now has 260k Miles and the only thing I have done to it is change the o2 sensor and changed all four suspensions. No major maintenance or breakdown to it yet.
Moral of the story NEVER get your oil changes done at the dealership They are total thieves and will do something to destroy your car, so they can sell you a new one. Learn how to change your own oil NOT hard
This is a very similar assessment of car care nut. A Master level Toyota mechanic. He's opened so many engines neglected of a simple change oil and it always end up with an engine rebuild. The math is good, even if you change oil twice or three times more than the normal, it is still the cheaper option compared to thousands of dollars in engine repair down the road.
It is very great info indeed for all of us who take care of their cars, but whoever is talking and cooking in the background has a very little to no respect to us listeners, c'mon guys, find a better place to record, other then that , great info. Thank you.
Hi David. Thank you and Mr. Kurosawa (GT-R Engine) for your advice on changing motor oil and oil filter. I have a Toyota Camry SE 2.5 liter 4-cylinder engine. So I am a pharmacist so I know very little about mechanical engineering. I have been watching some car assembly plants and I am fascinated by 4 stroke cycle engines. I notice that 4-cylinder and 6-cylinder engines are assembled with more automation. Most major car companies seem to use a lot more automation and fast moving assembly line in putting together 4- and 6-cylinder engines. The 8-cylinder engines are hand assembled by one worker. Everything is assembled by hand, no assembly line, and no automation. Does that make a lot of difference in the way the engine is put together and therefore more reliable in the long run. Or are that 8-cylinder engines more expensive, so they get the red carpet treatment? Are the 4-cylinder, 6-cylinder, or 8-cylinder engine more reliable in the long run? Also I noticed a lot of manufacturers use plastic parts on their engines. The intake manifolds are almost completely plastic. Do these plastic parts break down sooner when compared to the older metal carburetors? Or are the newer manifolds just different in design and no longer need a metal housing? I also notice that a lot of higher priced cars seem to use the same amount of plastic parts as the cheaper models? Does it make any detectable difference?
Thanks, me too:well, COLLEGE OF PHARMACY , **PURDUE, 1970, KAPPA PSI, ETC. !!

I change my oil and filter in my sr20ve every 5000km. Its cheep to change oil its not cheep to replace a engine as the heads are being take for rwd swaps
I'm gonna go against the tides here and say I've had my 2013 Prius to which I had been changing the oil at 8000km up untill 250,000km and after that I increased it to 13000-14000km between oil changes. The car runs pretty good and is at 400,000 right now. I really do believe 100% synthetic oils can give you the extended mileage unless you're always making short trips because then the engine is not warming up enough to get rid of the moisture contamination.
Toyota makes a great product and the world knows it. With that being said, I think the point was more; if you get 500,000 miles out of your engine doing it your way, you might get 800,000 out of it doing it his way. Actual amount will vary of course but you get the point.
I totally agree with Takumi. Service interval of 10,000kms/year whichever comes first, i will do a in between oil change at 5,000kms/6 months at home without changing the filter. The log book stamp is important when selling the car
@@dawicked2k8 His actual name is Takumi Kurosawa - and yes, he is also a master craftman which in Japanese is called Takumi. It's a coincidence believe it or not.
David, thank you and Mr. Kurosawa for discussing this important topic. The oil and filter has always been changed every 3,000 miles in my 4Runners, in addition to following the maintenance schedule.
There is one other factor not discussed. You need to change your oil more frequently if you have Direct Injection Engines. The oil gets contaminated sooner. I am not saying change your oil before 3k miles but if you say to yourself I am going to keep the car for 100k miles and think you can get away with 7k mile intervals... think again. Aim for 5k miles. Side note: I think you would be fine if you did it every 4k miles and change the filter each time. I don't like the idea of keeping a filter in for more than 5k miles. Once it gets 'clogged' the bypass kicks in and you are no longer filtering the the oil.
Great advice! Been doing this since the 70’s and have never had engine issues with any of mt cars. I had a ‘73 240Z and the oil was still honey colored after 3k. That struck me as very unusual. I changed it anyway.
I checked oil in my truck every 500 miles out of curiosity, and the color started to turn noticeably dark around 2750 to 3,000 miles, that was using non synthetic pennzoil in a non turbo engine, i must be OCD I enjoy keeping my vehicles clean inside and out and properly maintained although the longest time period I’ve kept a vehicle is 10 years, lol
David, as always, great post! Very informative. Thank you so much for your work.👍 I’d appreciate to have an opportunity to meet you someday as I also live in the Vancouver area. Again, thanks for your great videos!
I disagree. In the 60's it was recommended to change oil every 2000 miles. Today I follow the manufacturer's recommendations. Many of my newer cars were 7500 mile interval. I followed that and every one of my cars went over 250,000 miles with NO engine problems. Today I drive my Ford Ranger less than 5500 miles a year so I change the oil once a years....again with NO ENGINE PROBLEMS.
Glad to know a great engineer recommends more frequent changes with less expensive oil rather than using expensive oils and long change intervals! Personally, I never understood that thinking.
This is because you don't understand good true %100 synthetic oil and are ignorant of quality synthetic media oil filters also oil analysis and how you can get 400,000 miles on a 100% synthetic oil. No full synthetic oil will ever do this with out wearing out or destroying the engine.
He may be an engineer but that'd a joke...I've been a mechanic for 40 years and rebuilt 250 plus engines..only failures I've seen is due to lack of oil or overheating..catastrophic failures due to bad engine design..a good engine design the oil will look like honey between changed and will use little or no oil
I don't mind changing the oil more often but trying to get the cheapest oil is extremely wrong helping people in one way and destroying engines in another way just change it every 10km/6miles with a fully synthetic SP
well there's cheap oil w/ no api donut from a "brand" you've never heard of, then there's cheap oil like supertech from the makers of Mag1. you'll be totally fine with something like supertech
Mine is currently a Fors Escape 2012 ZD. After 3 years dealership maintenance, I DIY the oil change and replaced the engine oil with the recommended 5w30 and the oil filter once a year. The cheapest 100% Synthetic I use was the Hyundai Xteer Ultra Protection 100% Synthetic. Still using the car now without any issues with the engine.
I do my oil changes every 3,000kms using Mobil 1 Full synthetic extended performance. My engine is healthy it has 280,000kms, I'll be at 300,000kms after 20,000kms. Once I hit 300,000kms it'll be a matter of time till my Transmission needs to be replace. An engine will always outlive a Transmission. My 2007 Toyota Camry CE is 16 years old with a 5 Speed Manual Transmission, fully loaded with an SE interior. I still need to replace my 02 Sensor and Right Front axle. Also it needs an Alignment and a complete tube up new spark plugs and coli packs and a new fuel filter. I should inspect the power steering and Alternator belt as well.
10,000 miles will destroy an engine by six figure miles. There are other videos of shops tearing down Toyotas, fully serviced by dealers with wornout engines at 100k miles. Toyota recommends 10,000 mile change intervals. I wonder why 🤔 🤑
😬🙄😬😵💫🥺🤢🤮 That's what I was mentioning in another note here. The free, ( if you want to call it that) 2 yr. Toyota Maintenance Plan calls for 10,000 mile oil and filter changes🤮 to be performed by dealership. My car calls for 0W/8 oil per sticker. The sticker dealership put on car says they will use 0W/16 oil. You can bet that I will change the oil n filter at 1,000 to 1,500 miles after break in, then perhaps every 5,000 miles or twice a year afterwards. I will let dealership do their 10,000 mile oil n filter changes to honor the new car factory warranty and not void it. The problem is my car per sticker under hood calls for 0W/8 oil which is new for the MODEL YEAR 2023 Toyota Corolla HB XSE made in Japan. If you can find this oil (Toyota Parts Dept. can special order it for $18.00 to $22.00 per quart🤑 (maybe that's why the dealership service dept. uses the already difficult to find 0W/16 OIL)🤔?? Anyway, I want to use the 0W/8 oil when I do FIRST oil n filter change because that's what it is called for. Again this new oil is hard to find and expensive. I wish I could find an alternate brand and oil to use such as MOBIL ONE 0W/16, OR OW/20 since MOBIL ONE makes the Toyota Motor Oil brand from what I read???🤔🤔 This would make it alot easier to find and lower the cost instead of using Toyota Brand Oil as well as taking care of the oil viscosity of 0W/8 which is super expensive and impossible to find unless you buy it from Toyota Parts Dept.🤑. I don't want to be LOCKED in to purchase only from TOYOTA STEALERSHIP.🤑
What’s the ideal time interval if you don’t even get to 3K in a year? I change every 6 months on my Land Cruiser, 4runner TRD Pro and GX460. I plan to keep them “forever” but don’t drive them often. Infrequent use is also a potential problem for them. Thank you for these great pieces of wisdom. Love the channel.
if you use cheap oil, then every 6 months. If you use high quality oil (that actually advertises x1 year), then go one year (of course they can potentially go longer but still change it at 1 year)
Scott, you own three of the best vehicles out there in my opinion. I couldn’t think of three better ones to have. I bought my first Toyota, new in ‘83 - love ‘em.
Driving conditions, climate, city driving long distance driving, short distance driving and how hard you drive your car, all these factors come into play on how much you change your oil, so we have to differentiate with every individuals car. I have a Lexus is300h and I live in a city and do 6K a year, so I change yearly with Lexus 0W-20 oil and new filter with every change.
I live in Gifu Prefecture, my car is Toyota 86 with HKS GTIII-RS turbocharger and HKS S-type oil cooler. I use 5w-40 as much as possible or 5w-30 when I can't find what I want. Typically I will use Magnatek or Respo 86 or Castrol Edge. I replace the oil every 3 months or 3000 KM, whichever comes first along with a new filter. If I am short on money, I will replace at the next opportunity but in general I try to stick to my schedule. The car is a daily as well as taken to local tracks for drifting practice on occasion.

Tjank you
Thank you for the informative video. I am a new subscriber here. Appreciate videos like this.
My daily driver is a 1985 Toyota pickup. When it was new, I changed it every 3000. For the past decade I have changed it every 5000 miles. I change the filter every time. It’s hard to argue with success. I have about 300,000 miles on the stock 22RE engine.

Change intervals.

@@Odat depends om how much you drive, how fast u drive , how much weight u carrying, if ur changign oi filter etc
@@Odat When you realize how much a gallon of oil is expected to do inside an engine, you realize that replacing it before it begins to get dirty or diluted is so important. Especially if you have a DGI fuel system.
Well said
I agree 100%. I used to work in an automotive machine shop, it's sad to see how many crud filled engines would come in. It's cost very little to change your oil yourself.
This ^^. When I asked about the longer intervals between oil changes, my mechanic showed me the sludge filled top ends of a couple of Audis he was repairing. Both had under 100k miles. I’ve always done 3k oil changes. It’s like going to the doctor, preventative maintenance is cheaper in the long run.
This is what happens when you use a one size fits all approach. I had to get this straight as 5000 miles (conventional) usually lasted me 18 months and the oil was horrible smelling. The oil cap had a thick crusty layer on it. Never listen to someone trying to sell you a new car. They'll say it's 40000 mile oil. "Real high tech stuff son". 3000-4000 works for me or 2 years tops. If I just drove highway I'd still have to check the level. Also, oil should never be like black paint.

You do not need to change your oil every 3000 miles,total bs. Just change your oil and the filter every 5000 miles ,and your engine will last for a long time,but you must do it every 5000 miles.And every time you change your oil change your oil filer,it is not a good idea to change it every other oil change,do it every time ,oil filers are cheap.
I was a Tech for Ford in the 80's...we had Ford engineers come into the dealership to train us periodically. One session was on engine maintenance and covered oil changes. The engineer told us - "Forget mileage and time intervals. Different cars in different environments will tax their oil at different rates depending on the circumstances. You change the oil when it needs to be changed - that could be in a year - it could be in 3 months. Pull the stick, look at it, and check the color. And absolutely change the filter every time." He told us a story about an old guy who had an old Ford car and every month - every month - he took the car to the dealership and had the oil changed. When he finally traded it in, it had many years and many miles on it. Because of the unique circumstances involving the car, Ford had the car brought in and the motor disassembled for analysis. He said despite the years and mileage, the engine was pristine. Today's cars have a unique interplay in the engine with lubrication. It pays to change the oil as needed - not when "recommended."

This seals the debate for me and closes the chapter once and for all. I cannot thank you enough, David. This was so enlightening and educational at the same time on so many levels. I will be following through on your advice.
You're welcome, and thank you for your comments!
Yep. This is great.
As a part of his reasoning, would it be helpful to consider the average amount of miles driven per year in Japan (5,000-10,000 kilometers = 3,000-6,000 miles) vs USA (10,000-15,000 miles = 16,000-24,000 kilometers)? Approximate conversion 5,000 kilometers = apprx 3,000 miles. I would think that this drives the point of changing 2 times per year (winter run and summer run). I have personally averaged 10,000-13,000 miles per year. I also consider engine hours of run time and keep an eye for 150-250 engine hours per oil/ filter change. I have tried to stick with 5,000-7,000 mile/ 6 month oil/ filter change intervals. This does make me want to consider going to 3 times per year/ 3,500-4,500 miles. I have done 5,000 mile oil changes every 6 months and only change the oil filter 1 time per year and results were good with oil analysis.
@@sloanclick It greatly depends on driving style, but I always change mine in spring and fall, regardless. Winters here are hard, and I’m sure very hard on engines. You generally have more idle time, plus all the cold starts. Full synthetic oil has made cold starts much better than conventional oil did in the past, but it still puts extra wear and tear on all your moving parts.
@@stendecstretcher5678 What is the oil viscosity in your Corolla/year of Corolla? The new ones use some type of oil I never heard of or see much: 0W-8 and or 0W-16????
Another factor is time. If you have sports cars that don’t see a lot of miles per year, you still want to change oil annually even if you’ve only driven 1-2K miles in that time.
As a DIY car owner for the past 50+ years, a very important issue is New car oil changes. On a New car, after the 1st 1200 miles or so, I always change the oil & filter to remove any break-in oil and metal particles, during the break-in period. After that, I go with the 3k-4k oil and filter changes. I've Never had an oil related engine problem(30+ cars). My last car, a 1995 Lexus SC300 had over 203k miles and ran like new, when I sold it. (after 20+ year ownership).
The higher priced synthetic oils generally have a higher “Total Base Number” (TBN). The TBN is the component that neutralizes the acids built up in the engine. They also have a higher detergent package which keeps contaminants suspended in the oil until they can be filtered out. This is especially important for diesel engines.
Youre an Amsoil guy arent ya? ☺
@@Painting_Inspiration Well I have used AMSOIL products but not exclusively. Currently I am using MOBILE 1 0w-20 ESP X2 for my 2023 GMC SIERRA SLT with the LZ0 3 liter diesel along with an AC DELCO PF 66 oil filter.
It's Full synthetic for my LBZ (100%; Yes, I support Amsoil, what about it?), or G.F.Y.M.
@@NMTRUCKER I agree with you that the type of oil makes a difference. I not as much as Frequency. I have a daily driver 2002 GMC Envoy. It has 342k miles. I have done 95% of my oil changes. I use a good quality oil. Changed every 7k to 10k miles. The reason I can go that long. Is because it has a extra deep oil pan. It holds 7 quarts of oil and it's a straight inline 6 cylinder.
@@NMTRUCKER Well, I can't agree to your oil wisdom since you are using 0W20 oil. I switched after 3,000 miles to 5W30 Full Synthetic because of the heat of the turbocharger, considered 'Severe Service'.
I only drive about 3000-3500 miles per year & have my oil/filter service done every 6 months.
YOU SHOULD GET AN EV
Depends on your driving style and types of miles. Highway, city, long trips vs short. I think 3k is a good interval for japan bc its a smaller country with a more urbanized layout. For the US in more spread out areas i don't see any issue with a 5k interval.
stop being cheap. if you cant afford to change your oil every 3k, take the bus.
Agree with 5k, UOAs indicate it's fine for street car
@@tomr1107 We understand that some live in a Condo/Apartment Building the changes of Oils on his own would be hard. All Guys who race at the Tracks changed oils after their races and the Friends I knew then was not an Engineer - just a shop Welder Worker knew and did take out the Engine from his race car and Reset the Pistons Rings and of Course New Oil pumped in when the Engine was reinstalled ─ the Shop/ Office that we worked then is a Drilling Services Company ─ so they have all the Tools to haul out Heavy Engines or Oil Tools.

@@tomr1107I mean yeah if you’re driving a car from the 50’s and using oil from the same era😂
I do @ 5,000 miles. Twice a year for my F150 which gets under 10K miles per year (Mobil 1) and about 5,000 for a Toyota IM which isn’t 5 years old yet but just passed 155K miles. 3,000 miles would be close to monthly.
I change my oil every 5,000 KM as per Lexus’ recommendation. He’s speaking facts though. 2 of my relatives are at 500,000 and 750,000 KM on their LX and Land Cruiser respectively and they change every 5K km.
I change my oil every other day. Whether it needs it or not.
5000km, but how often do you change? Every 6 months or specific interval regardless of mileage?
People forget to change their coolant. That'll destroy the cooling system, heater tap, heater core, thermostat, causing leaks, overheating.
Change oil every 6 months regardless of mileage driven. I drive my 2005 Camry with well north of 350,000 kms. Almost 19 years old & runs like a clock. Take my car twice a year to Toyota - March & September. Toronto, Canada

@@jimlewis2395 If you drive 3,000 miles city and lets say drive it less than 10 miles a day and the engine won't find itself in operating temp, and oil changed lets say once a year, its possible to build sludge on that.

do you also change the filter every 3K?
Awesome video. I have huge respect for the master engineers in Japan. Thank you.
I usually get between 200,000 miles to 300,000 miles out of a car. I have followed changing the oil every 6000 miles as mfg recommended. I have never had an engine related breakdown due to oil. (belts break, idler pulleys, starters, alternators, freeze plugs etc). I live in a northern climate where salt is heavily used on the roads and the main issue is corrosion from salt.
I change it when it gets dirty.
Oil is cheap but engines are expensive.
I purchased my first car about 25 years ago and at that time the recommended oil change frequency was 3000 miles which I followed religiously and that car lasted me 12 years with little to no problems. Since then I’ve noticed manufacturers keep extending the interval from 3k to 5k to now 7k. However I always still change my oil about 4-5k miles based on my experience with my first car.
Yeah, manufacturers keep extending that time, because they dont want your car to last, so they can sell you a new one
@@jimlewis2395 oils are out there to make the changes last longer
@@jimlewis2395 This is not only because of longer intervals. Cars today are in general designed to be less reliable and overcomplicated. My first brand new car is now 15 years old and 250000km, just running fine. Oil change every 10k km from good brand 5W40 API SN.
Several more reasons for those longer reco interval:
1) The reco change frequency factors into “how green” the car is. By having artificially longer intervals, the same car is made to look more green on-paper.
2) Cost to maintain/operate. This is required to show on new car sticker. Same idea as #1, just slightly different reason.
@@cursem "Cars today are in general designed to be less reliable and overcomplicated" In general, an utterly ridiculous and uninformed comment. Some manufacturers build their entire reputation on reliability; Honda, Toyota, Lexus, Mazda. Some used to have a reputation for reliability but have lost it due to using cheap or plastic components that do not last; Mercedes, Audi, VW, BMW. Some are just poorly designed from the outset, but they are not designed to be unreliable. My Mazda 2 is 7.5 yrs old and has an O2 sensor replaced out of warranty for free and pair of rear shock absorber end-stops replaced. That's it. Reliability IS designed into the car. Unreliability is not.
My first car was 45 years ago. Then if a car lasted 8-10 years it was OK. Now an 8 yr old car with 100,000 miles has got many years ahead of it if properly serviced.
Don't the new Toyota Corolla 2.0 engines use 0-8 and or 0-16 motor oils??????? I have never heard of these as they are not as common as 5W-30 or 10W/30 engine oils.
It's just amazing that Porsche, with the 997 back in 2005, had a 20,000 mile oil & filter change interval. Before that, with the 996, it was 15k miles as if that was not bad enough. Imagine having oil in such an expensive and troublesome engine for so long.
They want to sell you a new car So of course they will tell you to do something that will shorten the life of the engine lol
I have a 1986 Nissan D21 4WD pickup with a V6 engine. It only has 210,000 miles on it, which isn’t much per year, but it has lived most of its life at an elevation of 9000 feet. That means cold temperatures in the winter and lots of cold starts. I have religiously changed the oil every 2500-3000 miles and it runs like a dream, is a true work horse, and I can still pull mountain passes in 4th gear. I’ve been a big believer in frequent oil changes for fifty years and my personal experience confirms the wisdom of doing it and now this engineer further validates the practice.
I have 2-71 Datsun 521 trucks having one for 46 yrs while the other 28yrs. Owners manual recommends oil changes at 2000 miles. I've been changing about 1250 miles including filter. They use no oil and run great after 53 yrs. Total.investment for both is $2300 usd. Never longed for anything else as they are super economical, easy to repair and highly modifiable still to.this day.
From my experience Nissan is just as good as Toyota. Never mind what Scotty Kilmer says.
Cold starts aren’t that bad if you have 0 weight winter oil. Engines build pressure the moment that it cranks. What does cause a delayed oil pressure build up is not filling your oil filter. Oil geeks did a test, and it took 5 seconds for the engine to build pressure, as opposed to having it filled in which it took half a second.
Even in the manual stated that Urban stop start traffic requires 1/2 interval oil change. Read the manual people. You don’t need expert’s opinions. The manufacturer already put that in the manual.
But never reinforces this fact, untill you go to make a warranty claim
But you are correct, city driving, extreme cold conditions, extreme hot conditions, dusty conditions, low grade fuel, towing a big boat or caravan ( RV ) are all severe duty cycle and need half the service interval.
So , just simply service the car at half the recommended interval, as the manufacturer is simply wanting to show cheap ownership costs and does not give a fcuk about your cars lifespan. The shorter, the better as far as they are concerned!
This is where I rarely get much agreement from other folks: in my opinion, you should change your own oil, and you should try to perform the oil change where you have plenty of time to let the old oil drain for a couple hours, in order to get every last drop of old sludge out as possible. Sometimes I'll pull my oil plug out, then go mow the lawn or do whatever else needs to be done. I'll come back in 2 or 3 hours and there will still be a slow drip. If you believe the thickest, sludgiest oil is going to take longer to make its way out, then I want to give it plenty of time to make the journey. I want as much old oil out of my truck as I possibly can. And if I have the time and patience to do it, why shouldn't I take my time and let it drip? It can't possibly hurt, and it could possibly help. Maybe 10 minutes is sufficient, but I don't mind waiting.
Also the engine needs to be warmed up to operating temp before you drain it which gets any sludge or contaminants back into suspension so it can be drained all out.
I just replaced my rod bearings and main bearings with the engine still in my truck. Oil was still dripping on my face, on my glasses and in my eyes 2 days after I had the oil pan removed. Also just for kicks (after 3 days of draining) I Shot my air compressor into the send line of my oil cooler and about 4 ounces of oil still came out of the return line. Expect about a half a quart of oil to still be in the engine and cooler lines no matter how long you let it drain or drip.
My car has 5.4 litres of oil in, but only ~4.7 comes out when changing the oil and filter. The rest is still in the engine.
This means there's little point in getting every last drop (you won't!) but your approach of going away to do something else is a much better use of time than standing there watching it 👍
Well 0.4 L is probably being held in the filter pleats. Filters absorb and hold a lot of oil. @@kramelbbiw
@@MadFox-jr6by The 4.7l includes oil still in the filter. Nissan put 5.4l in at the factory. The manual states the balance is still in the engine 👍
I sometimes went up to 10k miles and often 7k miles but regularly 5k miles on my Toyota Camry. Changed the trans fluid every 60k-80k and it went up to 400k engine and trans. Today I sold it to a family member and it’s still running. Same engine and trans 😊
What year was it?
If oil is synthetic, as long as it's clean, you don't have to change it. After 7,500 miles, the oil will be breaking down just a little, but 10,000 miles would be fine as long as it's checked often and remains clean.

It’s good to know you can switch from a viscosity to another from season to season. I will put 0w20 into my odyssey for winter and 5w30 for summer here in Toronto. Thanks
@@Americafirst-i8q second that. If engine does not call for 0-20, it means it needs a thicker oil when cold (larger tolerances) or vise versa. Specified oil viscosity is part of engine design.
No need to do that. I took two Odysseys from new to near the 200,000 mile mark and sold both of them still running like new without ever feeling the need to change viscosity from the factory recommendation--living in a northern climate with harsh winter. Removed valve covers and engine was squeaky clean at 180,000. Always followed the recommended viscosity for each and always changed the oil and filter on time. Fortunately, the maintenance minder on Odysseys fluctuates between 6,500-7,500 miles so that helped as well.
@@Shawn-ky2twif you change oil extremely frequently, maybe not matter
It really depends on the engine as well. Our Camry has about 250K miles and is still reliable. On average, we've been changing oil and filter every 5-6K miles.

Good info but what are the suggested time intervals for low mileage cars? My wife only puts about 4,000 a year on her Prius but I still change it every 6-months…once it only had 1,300 miles since last change.
Do the same
Absolutely spot on. I have had numerous vehicles since 1969 (1 222 879km - 763K miles, in 53 years so far) and have always changed my oil as prescribed with the cheapest non synthetic every 5000 Km (+- 3125miles) and never had a problem. Just two examples : Peugeot 404 sold after 300,000Km and a 1.2 litre Toyota Corolla station wagon which had a 4 speed box and a lower range differential than the sedan, making it rev at about 5500 rpm at 120kph which I sold after 46 years and 350 000 km and incidentally cost me 34cents per km (maintenance + purchase price+ petrol +insurance) for the duration I had it . I think a contributing contaminant to any engine degradation is the ingress of petrol into the oil, necessitating in more frequent oil changes than prescribed.
I’m ok…with regular oil…cause your changing it so often…synthetic gotten really cheap at Walmart…so I use synthetic…I will say 0/40 synthetic in the winter time is really nice…
Some of my cars got old with huge mileage...500,000 or more. I would change the oil once in a blue moon. Maybe every 15,000 - 20,000 miles, even longer. Cars had no book value, I had nothing to lose. I hoped they would die so I could get something new. But, they kept on running. What cars are these?
RWD Volvos, models 240, 740 and 940. Reliable and dependable even when neglected. Take that new car makers... You and your aluminum block engines with plastic manifolds... No amount of oil changes will fix cheap disposable engine.
Why not changing it every 1000 miles? If you want to keep your car a Million miles, change it every 500 miles? Guys, get real!
3000 miles would be every 1.5 months for me. Too frequent. 5000 miles would be reasonable.
I change my oil and filter every 3000 miles. When I bought my new 1992 chevy silverado shortbed truck with a 350 V8, I changed the oil at 500 miles to get rid of any tiny metal splinters that many have ended up in the oil, then every 3000 miles. I still have the truck, it's still in perfect condition, no accidents and no work on the motor, it still runs great with 40 pounds of oil pressure and 180,000 miles. I get asked by strangers regularly if I want to sell my truck. The answer is always no, and always will be. Funny story, I had to replace my air conditioning system recently and the guy I brought it to argued with me when I said, well, I guess after almost 30 years of service, it's due. The mechanic said, no, it's not the original air conditioning system. I said, yes, it is, I said, I should know, I bought the truck new. He was floored, he couldn't believe that the air conditioner lasted almost 30 years without any service being done to it. He said, that's just unheard of. I had him replace everything with original parts and he did a great job.
My first vehicle was a ‘99 Silverado 5.3L Vortec. I bought it with 250k miles from the manager of a dealership who used it to tow his boat and took very good care of it. I changed the oil every 3k miles and never had to do any engine work on it. I eventually destroyed the rear end (user error) and retired the truck at 500k miles. Change your oil frequently.
To me it still depends on your driving habits. Mostly long trips extends the useable range to 6, 7, 8000 m I less or more. Turbo shortens it due to the heat when the oil passes through the turbo unit. I drove a Ford Duratech 275,000 miles on a10,000 mile synthetic schedule and it was fine.
drivn habits & Quality of oil.
That is normal for toyota and honda 300k-400k. Camry can last 500k with ease. Others 200plus mark is something special
@Digital Camaraderie nearly all brands can do that with proper care. I get 300,000 miles out of Fords and Chevys as well as Japanese cars. Only difference is the Japs are a bit more reliable.
@digitalcamaraderie5685 look up a million mile ford crown victoria here on youtube
@VAspeed3 everyone don't do proper care.
It basically depends on your driving conditions and the varmint you're driving in. Sometimes you go as little as 3000 and you can be up a little bit above 5000. I actually change my oil so much that I change the oil filter every other oil change. And change my tranny oil every 10 to 12 thousand miles. I worked at one shop with a never change rear end oil. They have the 90 weight bucket there since the shop open once I talk to the owner about getting the 90 weight change and all these customers cars we sold a lot of 90 weight gear oil. Even gives the vehicles a little bit better gas mileage with fresh gear oil.
I drive mostly short trips, so I change my oil and filter quarterly. Moisture and acids build up and must be removed to support longevity.
it comes down to people beingEXTREMLY lazy
and cheap.
every car ive owned 3000 miles is it
great acurate video
What's never talked about is the timing of your oil changes. It's now so much the high Temps of summer that matter as much as the lows at night. Because cold starts are affected by the night Temps. So when summer ends consider changing to a thinner oil when night lows get below 40 degrees at night. Adversely, change to a thicker oil in spring when night Temps consistently remain above 40 degrees at night. Hopefully my advice will now save the human race!
I change my oil and filter twice a year, regardless of mileage (that comes down to about every 6.000km)
My 15 year old Mazda 6 seems to like it, as it has been bulletproof since I bought it new!
In short: Every 5,000 miles or every 6 months when using synthetic oil and a decent oil filter when mixed with city and highway miles.
In certain cases: Every 7,500 or every 9 months given that the car can display oil life % and I have experienced that the oil life goes to 5% after driving for 6,500 miles; or the oil life goes to 5% after 9-12 months of low mileage driving.
Mr. Kurosawa should know. "'Engine oil" is not oil in the traditional sense at all. Crude for example is just that. Not refined. Engineers over a 100 years ago realized that dumping crude into a crankcase guaranteed engine failure. Chemical refining and changing the physical molecular compounds were the key to the lock in providing a lower frictional coefficient between dynamic moving parts in an engine. Examining "Primitive"' diesel engines that still run today, use high pressure and lower thermal burdens to the lubrication system. The volatility of fuels has a major impact on the viscosity and lubricity of the oil. Remember Castrol commercials back in the day, Protects against thermal breakdown. Marketing jargon, with chemical engineering behind it. Why do F1 teams basically rebuild the engine after one race? They use shitty oil? not likely. Mr. Kurosawa mentioned a salient point: Contaminants. Where do contaminants come from and what are they? Free radicals from the metallurgic reactions between unlike substances as they are oxidized. If you drive 500 miles day you should replace the lubrication every day. Huh? It has been measured that when the typical oil change is performed only 78% of the volume is collected. The remainder is left to recirculate and cross contaminate the new lubricant. Why do "Oil' companies add zinc and organic materials? They are designed to bind with microspheres in suspension. If you are able, you should rebuild your engine in an anaerobic vacuum every time you change your "Oil".
Good advice but a clean air filter is also a must
New European market cars have 30.000 km service intervals (Volvo). That is mental, I wouldn't buy a used car with those service intervals.
My 2005 Chevy Trailblazer has had the oil and filter changed every 6000 miles I use Valvoline Full Synthetic. My engine runs as quietly at 175000 miles as it did when new and doesn't burn or leak any oil.
I’m the guy who does double oil
Changes .. makes sure I get the oil cooler and everything out or else 15-20% of the oil in the engine remains for another whole change. I use the fake synthetic group 3 oils on sale for the flush.. then amsoil or redline. 5k miles max usually 3500 or so
It appears my instincts were correct. Got sick of being ripped off for basic service so I decided to learn basic mechanics and do many jobs myself; oil, filters, brakes, et al. Oil change every 5-6,000 km with good quality oil. Thanks for this.
According to many oil analysis, oil+ filter change all 10 000km (or 1x per year) with full synthetic oil is ennough (insteed of 20000 to 30000km "recommended from the car brands!!!) change more often is oil waste ...on ALL modern engines, you have no choice for another oil type that the recommanded one , example for the Ford ecoboost 5w20 WSS-M2C948-B and not another, using oil without the right specifications did voids garantee in many cars brands!
You don't buy a car like the GT-R to be a cheap ass.
Change the oil every 3k not 4, Mobil one or equivalent.

I use Castrol Edge 0 - W 40 in my 2018 Challenger R/T Scatpack and change oil and filter when my oil gauge tells me I’m at or about 10% life expectancy as recommended by Dodge. 😎 I liked the fact that you mentioned Castrol as well even though they’re not sponsoring you. Well done video gentlemen! 😄
Euro Castrol is great stuff, I use 5w30 in my G35.
Very informative and useful content. Thank you however u have forgotten to specify the time duration if the car is less driven which can clock the 3000miles /( for how many years of duration)? So 3000 miles or how many years? Per oil change
I bought a new 2002 Tacoma V-6 Prerunner and I've changed the oil and filter every 5K miles and it is still going strong with 310K miles. It does not use any oil between changes. I never used synthetic, just regular old Valvoline 5W30. People say "use synthetic so you can go 10-15 K miles between changes"...no thanks. Synthetic is just as black and full of crud after 5K miles as regular oil. It's the dirt in the oil that grinds down the internal parts until the tolerances are gone and you start burning oil.
yes it may be just as black, but a good synthetic oil like Amsoil signature hold the particles in suspension so the oil can still do it's job. But of course you can use whatever you want and think what you want.
@@wally6193 Thanks, Wally...I'll go with the engineer's opinion.
Totally agree with you. The best engine oil is clean engine oil.
Smart. Few realize Toyota engines were lasting 600,000+ miles in the 70's & 80's when owners were using conventional oil.
@@stevevice9863
Exactly.
I disagree. I researched synthetics back in the 1990's and switched over to them on both cars and motorcycle.
I live in the Detroit, MI, suburbs. In 2003, facing a longer commute due to my office being moved, I bought a new Honda Accord. After breaking it in with conventional oils for the first 11,000 miles, I switched to an annual synthetic oil change using Amsoil synthetic oils. For the next 12 years, I put on substantial amounts of miles commuting to and from work and several substantial road trips. One year exceeded 20,000 miles, but the average mileage for that 12 year period was over 15,000 per year.
In 2014, I bought another Accord and the 2003 became the 'kids car'. Usage profile was now driving to college and residing in Kalamazoo, MI, a two hour drive from Detroit. Mileage numbers on average decreased substantially as now the car was being used mostly to drive just a couple of miles at a time to get to class or work or other activity. The number of miles per trip decreased which actually is more challenging to engine oil than a 60 mile daily commute where your engine reaches full operating temperature and can boil off any water (condensation).
Kids moved on, they no longer needed the car, so it now it's my 'dog car'. Driven daily to where I can walk the dog off the leash, about 12 miles per day.
At 257,000 miles, this car still starts the same way it did when I picked it up new at the dealer. My mechanic, who specializes in Japanese cars, has never indicated that any type of valve timing is necessary, as there is no valve noise coming off of the the top end. I still track gas consumption via spreadsheet and I see now that I get an average of 28 mpg as opposed to 33 mpg when most of the mileage was highway. Now averaging about 7,000 miles per year for the last five years. my annual oil consumption is less than 3/4 quarters quart per year. (yes, I'm very geeky at recording all of this).
Back in the 1980's, I took a course at the New York New School on maintaining your car. They called for 3,000 mile oil changes and I followed it diligently for over a coupe of decades. In 1996, my VW Jetta, with 90,000 something miles blew it's head gasket. The mechanic rebuilding the engine remarked that the original bore marks from the cylinder walls will still very apparent, despite usually being worn off by 40,000 or so miles. He attributed this to my dedicated oil changes at every 3,000 miles. So I do agree with the premise here that frequent oil changes are vital to long engine life.
But synthetic oils changed the game here in terms of how long an oil can last. Note we would not have our current aviation industry without synthetic oils as commercial jet engines would not run with conventional petro based oils as the service demands are too high. Synthetic oils simply withstand the temperature requirements needed in high performance engines so much better, along with slower oxidation and degradation. So bring all that in to a mild mannered auto engine such as a Honda Accord and you're easily good for a year and 20,000 miles of highway driving or 10,000 miles of short distance driving.
Economics here, I used to be able to point out significant savings when I was commuting. Since I don't drive as much since I've retired, current costs bring my once a year oil change to parity with the local oil change shops. I do my own oil changes. so all I pay for is the oil and filter. That's getting close to $100 per year per car. Local garages advertise specials close to $50 for a regular petro based oil change, and I'd need to do that twice a year if I adhered to a 3,000 mile oil change. But so far, I find great satisfaction in doing in my own oil changes. I know everything is being done right, I inspect my engine to see if there are any other indications of oil leaks or other problems, and I'm content with the fact that my engine is bathed full of the highest quality oil.
Finally, I always change my oil filter with each oil change. (Why take a shower and not put on clean underwear?). But I don't change my engine air filter if it has less than 5,000 miles on it.
Hope this helps. Happy to answer any questions you might have.

Can proof this Mr. Takumi is totally right
I use Royal purple high mileage with robust zinc and I use Lucas high mileage with a k&n filter. I change my oil every 3-4,000 miles and underneath my valve covers of every vehicle I’ve owned still looks like new with barely any wear. I work at a parts store and our commercial vehicles have had their oil change every 10,000 miles and they burn a little oil and also have lifter noise until it warms up. You can’t tell me the oil and oil stabilizer I use does not work. “Lubricant is the life of your engine or transmission”
It is an honor to meet your friend David. What an amazing car the Nissan GT-R is. My absolute favorite car as is the Lexus GX460 which I am purchasing very soon. What a great video and the oil change advice is worth its weight in gold! Love Castrol and used it for many years! Thank you!
haha I have a GX470 and a GTR - its a great combination ;)
I disagree with the Lexus service recommendations that state to change the oil & filter every year or 10,000 miles, whichever comes first. Ridiculous, I have already changed my oil at 1,000 miles on my new 2023 Lexus ES300h Ultra Luxury. And, I shall be changing it every 5,000 miles thereafter using Liqui Moly Special Tec AA 0W-16 and a Toyota oil filter 90915-YZZN1. Like Scotty Kilmer and The Car Care Nut recommend on YT, change your oil & filter regularly (six-months or 5,000 miles, whichever comes first under normal driving conditions) because oil & filters are cheap, engines are expensive.
This is interesting. I asked this question to a number of mechanics and they said you can do it every 5000 miles. I kept my last car doing this for 200,000 miles with absolutely no problems. It was a 2006 Saab 9-3. Now the second owner following that schedule has 254,000 on the engine, still changing it every 5000 miles. The trick is to use synthetic oil with the turbo engines so the oil will hold up. The oil is a little more expensive than the oil they are suggesting but you can keep your car running for 250,000 miles easy with 5000 miles per oil change. Then again, the USA is far more spread out than Japan so doing longer trips instead of shorter ones lengthens oil life as well.
The problem is that you'll never know exactly how long it would or could have lasted, with less frequent changes.
@@CadillacDriver Actually, we do. My brother owned the same car, with less frequent oil changes - following the oil life monitor he changed it every 9000 to 10000 miles. The motor gave out at 150,000. So he lost at least 100,000 miles of engine life following that longer interval. Do it at your own risk.
@@Buc_Stops_Here yeah but - again - even if your story is true about your bro having the same car (which I believe to be fabricated, or you would have put that in your OP as a point of reference) you still DON'T know. One identical model of car can last a lot longer than the next. It's not an absolute science.
@@CadillacDriver Just call this number and ask for George. He is a mechanic who works on Saabs. he will tell you the same thing I did. I am sure you don't believe mechanics either do you? Autotech, Danbury, CT. What evidence you have that cars that get oil changes far part last just as long? I bet no reliable mechanic will back up your statement.
I have always wondered about this. As a European, it's very surprising you can actually find non-synthetic oil to buy. In Europe mineral oil is reserved only for classic cars and you typically have to order it in a specialist shop. Even semi-synthetic oil is a rare thing to see, let alone recommended for use in a modern car. I've not seen semi-synthetic oil as a manufacturer recommendation since the '80s. Fully synthetic became the norm in aftermarket also, in the '90s. At the same time I've always wondered why outside of Europe people talk about 3000 mile oil change intervals when here the normal interval would be around 10k. Can someone tell me if the oils and recommendations really are different in North America, for example?
Only synthetic oil, every 5,000k/6 months, whichever happens first.
Awesome advice! Thanks David for bringing to your channel such a great engineer!
Meh. Use pure synthetics and change every 10k. I've been doing that for over 30 years and have run several engines up well over 200k with no issues.
Easy to keep track of it too. Just use the odometer as your mileage record and simply change it on the 10s.
As for thinner in the winter, thicker in the summer, that's the whole reason multi-viscocity oils were invented; so you didn't have to change it seasonally. 10w30 is actually a 10-weight oil with polymers in it to make it thicken as it heats up and perform like 30-weight.
Thank you for sharing Takumi Kurosawa thoughts about oil changes. I love my vehicles but I don't drive them enough to pass the 3k miles mark a year therefore my personal policy is to change the oil and filter at least once every 11, or 12 months tops.
I do the same, annual change, due to low miles, and I never drive unless I can get the car thoroughly heated up.
@@UncleKennysPlace that is excellent advice. It staves off some of the oil dilution by condensation. And since cold engines run rich, a cold engine has some chance of oil dilution with gasoline. An engine with some wear is expected to burn at least a tiny bit of oil. The problem is that the oil level may appear normal but it's been replaced by condensation from combustion, deposits and raw fuel. So what I do is change any brown oil or really sour rubbery smelling oil. Especially conventional! But that product has evolved a little...
You know your car care!
I had an audi b7 2.0 tdi , 19k oil changes and sold it on 201,000 miles with no issues. Oil was 5w 30 fully synthetic. So all of this is just BS.
I buy the best oil and filters and change every 4000 miles, I always have, and always will. I plan to do the same for the 23 Lexus LX 600 I just bought, cheap insurance on a magnificent and expensive vehicle, I did the same on my 18 LS. Excellent video and interview.
Seems there's some variability that isn't addressed by a 3,000 mile interval. If it's a daily driven commute vehicle all highway, if it's full synthetic oil, etc. The oil will last much longer than if it's driven in stop and go traffic with cheap conventional. If you really want to know how often you need to change, get the oil analyzed at your change interval and you can find out if it's starting to break down or getting high on contaminants. There are Toyota engines that have gone over 1,000,000 miles with nothing but 10,000 mile change intervals.
If you don't drive you vehicle very much 5K per year, should i change oil at 3K or is there time frame (every six months) for a vehicle that isn't driven as often?
Personally I would change it Only once a Year in your case just before winter, Unless you drive it Really hard meaning flooring it every where you go, Because it does make a difference in How you drive, In your case the Best thing for your Vehicle is driving it at say 75 mph for say 20 to 30 miles once a month would be very beneficial because it boils any moisture out of the engine when you do this and burns carbon off of the Valve etc, I would also run only top tier Gasoline if that's all you drive.
@@raymondreiff8170 Thank you I will do this
I change it twice a year due to weather change. Once in spring time and once before winter. That way, you are not having to do it in the cold if you change oil yourself.
I agree, change oil every 3000 miles , good advice.😊👍
Hey if I used a synthetic oil. Do I have to change every 3,000 miles? Maybe if you using a regular oil you change every 3,000 miles but not synthetic oil it's too expensive. Plus future vehicles are electric no more oil change etc.
Very good advice. My 2010 Rav4 (4 Cylinder) was serviced at a toyota dealer every 8000 KM (5000 Miles), the engine lasted only 200,000 Km(about 120000 Miles) before it started giving me trouble. I traded the Rav4 after 13 yrs. Was expecting the engine to last at least 300,000 km.
What kind of trouble? I doubt the oil changes had anything to do with that.
@@StubProductions I was thinking the same thing. I have a 2007 Corolla and oil is changed every 5k miles. My corolla now has 260k Miles and the only thing I have done to it is change the o2 sensor and changed all four suspensions. No major maintenance or breakdown to it yet.
@@jepoydaninja 5,000 is a good standard oil change interval. That’s what I use.
Moral of the story NEVER get your oil changes done at the dealership They are total thieves and will do something to destroy your car, so they can sell you a new one. Learn how to change your own oil NOT hard
I have to agree. I have become suspicious of dealers.
I can my oil twice a year ( about 5000-5500 miles ) using full synthetic. The owners manual says every 7500 miles
This is a very similar assessment of car care nut. A Master level Toyota mechanic. He's opened so many engines neglected of a simple change oil and it always end up with an engine rebuild. The math is good, even if you change oil twice or three times more than the normal, it is still the cheaper option compared to thousands of dollars in engine repair down the road.
It is very great info indeed for all of us who take care of their cars, but whoever is talking and cooking in the background has a very little to no respect to us listeners, c'mon guys, find a better place to record, other then that , great info. Thank you.
Hi David. Thank you and Mr. Kurosawa (GT-R Engine) for your advice on changing motor oil and oil filter. I have a Toyota Camry SE 2.5 liter 4-cylinder engine. So I am a pharmacist so I know very little about mechanical engineering. I have been watching some car assembly plants and I am fascinated by 4 stroke cycle engines. I notice that 4-cylinder and 6-cylinder engines are assembled with more automation. Most major car companies seem to use a lot more automation and fast moving assembly line in putting together 4- and 6-cylinder engines. The 8-cylinder engines are hand assembled by one worker. Everything is assembled by hand, no assembly line, and no automation. Does that make a lot of difference in the way the engine is put together and therefore more reliable in the long run. Or are that 8-cylinder engines more expensive, so they get the red carpet treatment? Are the 4-cylinder, 6-cylinder, or 8-cylinder engine more reliable in the long run? Also I noticed a lot of manufacturers use plastic parts on their engines. The intake manifolds are almost completely plastic. Do these plastic parts break down sooner when compared to the older metal carburetors? Or are the newer manifolds just different in design and no longer need a metal housing? I also notice that a lot of higher priced cars seem to use the same amount of plastic parts as the cheaper models? Does it make any detectable difference?

I change my oil and filter in my sr20ve every 5000km. Its cheep to change oil its not cheep to replace a engine as the heads are being take for rwd swaps
I'm gonna go against the tides here and say I've had my 2013 Prius to which I had been changing the oil at 8000km up untill 250,000km and after that I increased it to 13000-14000km between oil changes. The car runs pretty good and is at 400,000 right now. I really do believe 100% synthetic oils can give you the extended mileage unless you're always making short trips because then the engine is not warming up enough to get rid of the moisture contamination.
Did you ever have to change your head gasket? My 2013 Prius had its gasket fail at 180k miles.
Toyota makes a great product and the world knows it. With that being said, I think the point was more; if you get 500,000 miles out of your engine doing it your way, you might get 800,000 out of it doing it his way. Actual amount will vary of course but you get the point.
@@johnnywang206 mate..at 180k you have had a fairly good run....i wouldnt be too worried about that.
@@4gotten_1 though after that long you'd have enough saved up for another used car by not changing it every 3k
@@RennieAsh Maybe.
Next week: Nissans master transmission tech teaches us how to make your new transmission last over a hundred a miles!
I totally agree with Takumi. Service interval of 10,000kms/year whichever comes first, i will do a in between oil change at 5,000kms/6 months at home without changing the filter. The log book stamp is important when selling the car
lol Takumi is not his name, i dunno why the uploader said Takumi was his name.Takumi translate to "Craftsman", its like a title that you earn in Japan

@@AutomotivePress oh ok I didn't know that, thanks for clarifying
From now on I will change my engine oil every 500 miles so my car will last for 1 Million miles!
David, thank you and Mr. Kurosawa for discussing this important topic. The oil and filter has always been changed every 3,000 miles in my 4Runners, in addition to following the maintenance schedule.
What about oil grades n changing interval frequency video ?
There is one other factor not discussed. You need to change your oil more frequently if you have Direct Injection Engines. The oil gets contaminated sooner. I am not saying change your oil before 3k miles but if you say to yourself I am going to keep the car for 100k miles and think you can get away with 7k mile intervals... think again. Aim for 5k miles. Side note: I think you would be fine if you did it every 4k miles and change the filter each time. I don't like the idea of keeping a filter in for more than 5k miles. Once it gets 'clogged' the bypass kicks in and you are no longer filtering the the oil.
Great advice! Been doing this since the 70’s and have never had engine issues with any of mt cars. I had a ‘73 240Z and the oil was still honey colored after 3k. That struck me as very unusual. I changed it anyway.
It shouldn't be honey colored after 3000, If it's pulling out contaminants, it should start looking darker.
I checked oil in my truck every 500 miles out of curiosity, and the color started to turn noticeably dark around 2750 to 3,000 miles, that was using non synthetic pennzoil in a non turbo engine, i must be OCD I enjoy keeping my vehicles clean inside and out and properly maintained although the longest time period I’ve kept a vehicle is 10 years, lol
David, as always, great post! Very informative. Thank you so much for your work.👍 I’d appreciate to have an opportunity to meet you someday as I also live in the Vancouver area. Again, thanks for your great videos!
I disagree. In the 60's it was recommended to change oil every 2000 miles. Today I follow the manufacturer's recommendations. Many of my newer cars were 7500 mile interval. I followed that and every one of my cars went over 250,000 miles with NO engine problems. Today I drive my Ford Ranger less than 5500 miles a year so I change the oil once a years....again with NO ENGINE PROBLEMS.
Glad to know a great engineer recommends more frequent changes with less expensive oil rather than using expensive oils and long change intervals! Personally, I never understood that thinking.
This is because you don't understand good true %100 synthetic oil and are ignorant of quality synthetic media oil filters also oil analysis and how you can get 400,000 miles on a 100% synthetic oil. No full synthetic oil will ever do this with out wearing out or destroying the engine.
He may be an engineer but that'd a joke...I've been a mechanic for 40 years and rebuilt 250 plus engines..only failures I've seen is due to lack of oil or overheating..catastrophic failures due to bad engine design..a good engine design the oil will look like honey between changed and will use little or no oil
I don't mind changing the oil more often but trying to get the cheapest oil is extremely wrong
helping people in one way and destroying engines in another way
just change it every 10km/6miles with a fully synthetic SP
well there's cheap oil w/ no api donut from a "brand" you've never heard of, then there's cheap oil like supertech from the makers of Mag1. you'll be totally fine with something like supertech
Mine is currently a Fors Escape 2012 ZD. After 3 years dealership maintenance, I DIY the oil change and replaced the engine oil with the recommended 5w30 and the oil filter once a year. The cheapest 100% Synthetic I use was the Hyundai Xteer Ultra Protection 100% Synthetic. Still using the car now without any issues with the engine.
‘Fors Escape?’ Never heard of that brand? 🧐🙄😂
I do my oil changes every 3,000kms using Mobil 1 Full synthetic extended performance. My engine is healthy it has 280,000kms, I'll be at 300,000kms after 20,000kms. Once I hit 300,000kms it'll be a matter of time till my Transmission needs to be replace. An engine will always outlive a Transmission. My 2007 Toyota Camry CE is 16 years old with a 5 Speed Manual Transmission, fully loaded with an SE interior. I still need to replace my 02 Sensor and Right Front axle. Also it needs an Alignment and a complete tube up new spark plugs and coli packs and a new fuel filter. I should inspect the power steering and Alternator belt as well.
Cheapest oil … that meets the certification please!
Yeah, this video is missing key important points. Also recommending to change viscosity without mention of engine specs? This video is dangerous.
10,000 miles will destroy an engine by six figure miles. There are other videos of shops tearing down Toyotas, fully serviced by dealers with wornout engines at 100k miles. Toyota recommends 10,000 mile change intervals. I wonder why 🤔 🤑
😬🙄😬😵💫🥺🤢🤮 That's what I was mentioning in another note here. The free, ( if you want to call it that) 2 yr. Toyota Maintenance Plan calls for 10,000 mile oil and filter changes🤮 to be performed by dealership. My car calls for 0W/8 oil per sticker. The sticker dealership put on car says they will use 0W/16 oil. You can bet that I will change the oil n filter at 1,000 to 1,500 miles after break in, then perhaps every 5,000 miles or twice a year afterwards. I will let dealership do their 10,000 mile oil n filter changes to honor the new car factory warranty and not void it. The problem is my car per sticker under hood calls for 0W/8 oil which is new for the MODEL YEAR 2023 Toyota Corolla HB XSE made in Japan. If you can find this oil (Toyota Parts Dept. can special order it for $18.00 to $22.00 per quart🤑 (maybe that's why the dealership service dept. uses the already difficult to find 0W/16 OIL)🤔??
Anyway, I want to use the 0W/8 oil when I do FIRST oil n filter change because that's what it is called for. Again this new oil is hard to find and expensive. I wish I could find an alternate brand and oil to use such as MOBIL ONE 0W/16, OR OW/20 since MOBIL ONE makes the Toyota Motor Oil brand from what I read???🤔🤔
This would make it alot easier to find and lower the cost instead of using Toyota Brand Oil as well as taking care of the oil viscosity of 0W/8 which is super expensive and impossible to find unless you buy it from Toyota Parts Dept.🤑.
I don't want to be LOCKED in to purchase only from TOYOTA STEALERSHIP.🤑
What’s the ideal time interval if you don’t even get to 3K in a year? I change every 6 months on my Land Cruiser, 4runner TRD Pro and GX460. I plan to keep them “forever” but don’t drive them often. Infrequent use is also a potential problem for them. Thank you for these great pieces of wisdom. Love the channel.
Why even get something meant to go 300k miles if you barely even drive them. Go buy something luxurious for your
if you use cheap oil, then every 6 months. If you use high quality oil (that actually advertises x1 year), then go one year (of course they can potentially go longer but still change it at 1 year)
Scott, you own three of the best vehicles out there in my opinion. I couldn’t think of three better ones to have. I bought my first Toyota, new in ‘83 - love ‘em.
I’m definitely a Toyota enthusiast like david!
I think your 6 month schedule is spot on for vehicles that don’t reach 4k intervals during the timeframe. You have a nice fleet
Oil is always cheaper than an engine replacement
Love to hear his opinion on a pre-ignition electric oil pump to bring operational oil pressure to normal level BEFORE turning the engine over!
Some Komatsu plant equipment have them.
My household’s cars get an oil change every 6 months. That’s usually 4K miles, Mobil 1 and OEM filters only.
Driving conditions, climate, city driving long distance driving, short distance driving and how hard you drive your car, all these factors come into play on how much you change your oil, so we have to differentiate with every individuals car. I have a Lexus is300h and I live in a city and do 6K a year, so I change yearly with Lexus 0W-20 oil and new filter with every change.
I live in Gifu Prefecture, my car is Toyota 86 with HKS GTIII-RS turbocharger and HKS S-type oil cooler. I use 5w-40 as much as possible or 5w-30 when I can't find what I want. Typically I will use Magnatek or Respo 86 or Castrol Edge. I replace the oil every 3 months or 3000 KM, whichever comes first along with a new filter. If I am short on money, I will replace at the next opportunity but in general I try to stick to my schedule.
The car is a daily as well as taken to local tracks for drifting practice on occasion.
People in Japan have great care for cars but not only. This car will last a long time.
