Thank you everyone for your comments. A number of people have asked for a data as a backup - but you have to remember that when it comes to predicting the durability of engines, the best way to do that is to take the engine apart. You will then clearly see the residue of the oil, condition of the inner components etc, and often times the condition of the engine itself does not correlate with the condition of the engine oil. So it is very deceiving - and dangerous - to assume that the engine is in good condition due to the good condition of the oil (through data and analysis). People like AMD from Car Care Nut, myself as an automotive engineer, and Mr. Takumi Kurosawa (Nissan GT-R engine leader) have all taken hundreds of engines apart and correlated the condition to the frequency and type of engine oil used. That's the best type of "data" and most accurate way to predict the engine condition (you can see it). Because I have taken apart hundreds and hundreds of automotive components apart, I know exactly what needs to be done to take care of automobile components and parts (not just engine), and my recommendations are based on these experiences. My two good friends AMD and Mr. Kurosawa will back me and support me as they have the same insights and ideas as in this video. I hope this helps you understand how I came up with my recommendations. At the end of the day, you are free to decide what to do based on your own experience and knowledge. I am simply sharing my insights based on 35 years of working with cars inside and out.
Criteria A - Maximum Longevity (10 - 20 years) - 400,000 to 800,000 kms - or even longer.
Change oil every 3,000 miles / 5,000 kms (6 months or earlier)
Criteria B - Good Longevity (4 - 10 years) 160,000 to 400,000 kms
Change oil every 5,000 miles / 8,000 kms or once a year or earlier - whichever comes first.
Criteria C - Minimum Frequency (1 - 4 years) 40,000 - 160,000 kms
People leasing or financing - who don't value longevity are recommended to follow the interval in their owners manual.
Oil is able to keep its lubrication properties for a very long time. However, oil does get dirty and air and gas contaminants do get into the mixture Hence, why time is just as important as distance.
I have huge respect for David, AMD from The Car Care Nut Channel and every mechanic who offers sensible advice.
I live in Alberta, Canada and drive a Corolla Hybrid. I use a 4 month oil change interval.
January - April
May - August
September - December
I drive less than 15,000 kms annually (suburban 60% & highway 40%)
Car has been rust-proofed and PPF added because the Alberta government has a ton of salt and sand added to the roads during the long winter months. The same applies to much of Canada.
Toyota Corolla Sedan owners are advised to use 0W-16 oil... The weight is written on the oil cap.
Criteria A - Phenomenal owners
Criteria B - Fantastic owners
Criteria C - Are not bothered about the longevity of their vehicles and less likely to maintain them - Zero respect.
Thank you David & The Car Care Nut
Are you trying to say that engine oil analysis does not give good information on the condition of the oil? You seem to also be saying you cannot tell how good the oil still is based on these tests? Are you saying this evidence, that you can also 'see' the actual test results, such as amount of contaminants, amount of wear particles, etc., somehow isn't reliable in predicting both whether the oil is still in good condition, or how much longer it will protect your engine?
What actual evidence are you basing such a claim on?
Long-haul truck companies routinely use these engine oil services to evaluate their oil's condition. Are they wasting their money?
Thanks for this comment. There is something that has been bugging me with oil analysis. Like it might be missing some important things? I feel like we tripled the oil change mileage and at the same time added direct injection, turbos, and some questionable fuel with ethanol. I don't think oil capacity has increased much at all. Which all points to it being harder on the engine oil. I also feel that longer drain intervals will lead to more oil leaks but I have no proof of this. A major oil leak is almost as bad as an engine failure if it costs me $7000 to take the engine out and fix it. It just seems too easy to keep doing 5K oil changes instead of that. Thanks!
@@garymaclean6903 Thank you for your comments, I appreciate you've taken the time to reply. However, you've completely misunderstood what I was trying to say. Yes the oil analysis will tell you the exact condition of the oil itself. However, at 3,000 or 5,000 miles, the oil would still be in good condition and would not have deteriorated enough to be a concern. Testing at these mileage would be waste of time. I would say beyond 7,000 miles the actual condition of the oil would matter. But unlike long-haul truck industry, you would not normally need to test the oil to see how long "you can keep driving" while keeping the same oil. You would normally try not to extend that much just to save a few quarts of oil - this might matter to long haul trucks but in automobiles, the cost of oil is cheap enough that you can change them out while the oil is still in good condition. I have taken engine apart, tested oil, tested various parts, and examined data to know this as a fact. You cannot compare long haul truck industry methods to modern consumer oriented automobiles where you don't need to prolong the oil until the oil is almost end of life.
Thanks for the information. What's your recommendation on a car that isn't driven on the road but I start it every few.monyhs so it runs and keeps seals from drying out. It sits with synthetic
Great advice on how to make an engine last. Personally I don't care if I'm planning on keeping my vehicles basically forever or if I'm going to get rid of them every 50,000 miles. I'm going to treat every vehicle the same. I want to know when someone purchases something I bought new, broke in, and maintained, that they're going to buy something that could last another quarter million miles. I don't care if that person is a grandkid or some stranger I'll never meet. It's just the right thing to do.
Agree 100%
Much respect to the people who take care of their vehicles.
Especially those who change their oil at frequent intervals as outlined by David and AMD from the Car Care Nut channel.
Furthermore, the people who change their cars more frequently generally have higher incomes.
So an extra oil change per year shouldn't put them in any financial hardships in the first place..
Agreed. Everyone should have this mentality. It's poor behavior and shows lack of compassion to your fellow citizen to do otherwise.
Thank you for your post, there are a lot of people who will never be able to buy a new car and they are so lucky to buy a used car from people like you. I think your post is as important as the video itself, if not more.
100% agree. I'm disappointed that a channel like this would even encourage screwing over used car buyers.
@@derek2479 I don't believe that is what David is advocating and I definitely didn't mean for what I wrote to come off that way.
2007 4Runner. Oil and filter change every 5k and transmission flush every 60k. Currently 343k miles. Runs and drives as good as the day I got it. Burns no oil, no leaks, transmission is milky smooth. Wouldn’t hesitate to jump in and drive it from Georgia to California and back. Just a great vehicle made in a place where they value work ethic.
Time to switch to 3000. Just from wear and tear it's getting more blowby which is introducing more unburned fuel into the oil and contaminating it faster.
Go for 500,000 and more...
I have 435k on my cheap Hyundai, changing every 3000 and trans oil every 30,000
My trans oil changes are simple drain and fills. Drains one gallon per change.
You've bought the sweet spot of peak Toyota engineering. 2006-2009
Awesome!!!
I'd be interested in knowing how often you change your transmission/diffs/transfer case fluids. And at what mileage did you do the first changes?
@@TheBeatenPathstranny every 60k, all diffs every 20k, I lube all the lube points every oil change . Seen many 5th gen’s with 150-200k miles still running strong as well.
On the transmission do you do a flush total fluid Change or what’s in the pan?
I'm an "A" guy. I've always bought new, kept them for 10+ years, although nowadays I use synthetic and go for 4-5k miles.
I am disappointed in the "C" recommendation. This is why I don't buy used. The attitude is basically "I don't care if who gets it next will have a long-term car. I got mine.".
couldn't agree more..very well said 💯
I was thinking the same thing. Basically C is encouraging bad maintenance.
Why is it bad to use the manufacturers recommendation? Unless they want the car to fail so you have to buy another one. If that’s the case why would you be a repeat customer if the engine failed prematurely on their recommendation?
@@JHKCF Basically every driver have different driving conditions which does not fit the ideal manufacturer oil change interval. You may have short trips like driving to work every day for 5 minutes which does not allow the engine to fully warm up. You may be a driver that does mostly city driving and that effects the engine oil. On the other hand you drive mainly highway driving which is good for the car. Then weather plays a part in which dusty and extreme freezing condition or very hot desert condition will effect engine oil wear. So the 10,000 mile oil change the manufacturer recommended is not ideal for that driver that drives short trips mainly in the city. On the other hand the driver that drives mainly highway for an hour every day the 10,000 mile oil change in mostly warm weather above freezing would be good for the engine.
@nowayout8639 There are historically two schedules of maintenance for oil/filter changes. One is for those who drive in clean conditions and on longer trips. The other schedule is for what is considered to be harsh conditions with short trips and lots of dry dust and or sand.
Small point of disagreement , The MOST important filter on your engine is NOT the oil filter but rather its the air filter . By a ratio of media filtered ,the air filter works harder that ANY of your filters . Not to diminish the importance of the oil change but rather ADD the air filter onto the list of IMPORTANCE on your maint program! rule of thumb: it takes only ONE oz of dust to destroy 100 Cubic inches of engine displacement
Own two Lexus, 17yrs old and 13yrs old. Change oil and filter every 6mths or 5000miles, with mobile 1 full synthetic. No engine problems at all, to include no oil burning. I use the same interval for my son’s Prius Prime. Other than 1 hr of time, the cost for oil change is about $40 (I do my cars oil change. Can’t trust jr. Mechanics). That’s cheap for worry free engine.
Couldn't have said it better myself, I also own 2 Lexus's with Mobil 1 stacked to the ceiling in my basement. Oil is cheap and motors are not. I just bought a dozen Toyota filters recently. In my 45 years of driving, no one has ever changed my oil but me.
I'm from England, i change my oil every 10,000 miles i have no issues either
Lexuses.
@@charley95sheridan44 I agree, I’m 73 and the only person to change the oil in all my vehicles, even the numerous new vehicles I bought I have never let the dealership give me a free oil change. When I lived in town with a lot of short trips I changed oil and filter at 2k miles and after I moved out in the country I started going to 3k miles. I also use Mobile 1 0w40 European blend oil which has a very good additive package that I prefer, also it’s just under $5.00 per quart when you buy it in the 3 jug carton from Wally World.
A lot of people who don’t have garages (condos, apartments , townhomes) are forbidden to do any car work….. leading to longer oil changes…
I let the dealer from whom I purchased my 03 Toyota Sequoia change the oil every 5k miles. I purchased the lifetime oil change plan, which cost me only $500 and a $10 environmental fee per oil change. At 301k miles, the 4.7 L engine is still going strong.
Nice video
Not bad. You're currently at less than $19 per oil change including the environmental fee.
Have had several dealers, cheat, and not change filter, have caught several doing this, so change myself now
@@garydale8874 Some manufacturers and service managers recommend only changing the filter every other drain interval [not me, I don't do that].
@@michaelclark9762 They might recommend that, but when I am paying them to do both, they should.
In a previous job I got to visit the lab where a very well known brand of oil was formulated and tested. The chief engineer told me that if I wanted to have virtually zero engine wear I should take the recommended service interval and halve it. So 12k miles becomes 6k and so on. I followed his advice and my last car was 19 years old when it had to be scrapped due to rust. But the engine still ran like a sewing machine.
You wasted your money on excessive oil changes when you should have been spending it washing the car so it wouldn't rust
@@TheRealSykx Trust, 19 years of salty winters is not bad. It wasn't the exterior body that rusted, it was everything underneath. Brake lines, exhaust, springs, brackets, subframes, ABS rings etc. Wasn't worth replacing all of it.
@@Haawser ,,
same here ,
19 yrs of rust on mechanic components.
Doing another round of rust removal this summer and will do some protection again .
Any suggestion on the protection ?
@@enzoh7763 Waxoil or Dinitrol is easy to apply. It's just not as permanent as I'd like. Have to redo the stuff every couple of years. But worth it.

My step father was a master mechanic and I tend to take amazing care of cars regardless of how long I intend on keep it. I 100% agree with your recomendations
David, my 4Runner’s have lasted many trouble-free years as I have always changed the oil and filter at 3,000 miles. Thank you for your expertise and recommendations.
3,000 is what I did for decades while using conventional oil. With full synthetic it’s a waste of money and go 6,000
A 4Runner can run forever! Every 5-6,000 miles is fine! You would be surprised the engine will be just fine! 🚙
I use Amsoil signature and go 10k....never had a problem
Nothing wrong with doing it more often. Props for being on top of it.
@@srf6161 It is better for your car to use a cheaper oil and change it every 5000 miles!
I have a 2003 Highlander V6 with 160,000 trouble free miles. I change the oil every 5000 miles. I like this number and recommend it to friends because it is easy to keep track of. Whenever the car hits the next 5000 mile increment it is time to change the oil. I also keep a spreadsheet of all maintenance ever done but find the 5000 mile increment easy to remember.
Mostly long commute every day on the Interstates?
@@motleydude73
Plus, 5k is also a good time to rotate your tires.
I just bought a '23 Ram EcoDiesel (last ones!) and I'll do the first change at 1.5k, then 3k, 5k and every 5k afterward.
My Retirement Ride, lol! 👴🏻
@@motleydude73 What brand oil & filter do you use? How many months does it take you to hit 10k miles? Is it mostly highway miles or stop and go? Long trips or short trips? Do you live in a colder or warmer climate? Lead foot or drive like a grandma? Top tier gas or not? Planning to keep the car until 250k miles or 450k? All of these make a difference. Remember there's no one right answer for when to change the oil to minimize risk of issues, it's completely conditional based on those and other factors. On top of that it's simply about risk, there's no 100% guarantee of issues (or lack of issues) regardless of how often you change oil, or when those issues will arise. This is why it's a never ending "debate." People think THEIR way is THE way for everyone.
@@motleydude73 Nobody does? Dude how many people think it's "normal" for higher mileage cars to burn oil?
this is the BEST EFFING REPLY HERE!these anal people changing oil at 3.234 miles because they have time on their hands,and 3,235 miles is too much!@@motleydude73
I'm glad to hear you quote AMD, the Car Care Nut, as I follow his recommendations to the letter for my Toyota. Thank you!
I too follow AMD and learn alot from him. 👍
AMD is the man! 👍
Ahmed is the man and his recommendation is a flat out 5k interval.
Except for a few things like what oil to use. But hey go by the manual as best as your conscience can manage it.
OW- O8, OW-16 ... sorry no can do.
@@Shawn-ky2tw if you can, what is Ahmed's channel...thanks
First thing: manufacturers recommendation on severe service schedule is my baseline. I typically do a 5k mile OCF using whatever synthetic OEM spec oil I can get on sale, a high quality filter, and the occasional lab analysis. I also do other fluids at 60k for trans, 90k for coolant, and brake fluid every three years. Service on 4wd transfer case and differential is approximately every 30k - 50k depending on the component. I’m not afraid to go longer on the OCF if on a long over the road trip and have done an 8800 mile change with lab analysis showing the oil still held additives and no degrading wear byproducts. Excellent summary sir. Grease is cheaper than steel.
Toyota owner's manual says 5,000 miles under severe conditions. They define severe as a hot climate, a cold climate, or a lot of stop & go city driving. I have also read that it should be changed at 6 months, regardless.
Yep, what they (and others) call severe is actually the average owner's usage.
10k these days.
I leased a Corolla and they wanted to change it at 10k intervals
@@mikeprice8307 One of the (growing) problems is "MARKETING". It's a sales pitch, to offer longer-interval servicing as a requirement (hence cheaper and less inconvenient to the owner). The executives go to the engineers and ask what is the MINIMUM oil change distance to get the vehicle *past warranty* - not necessarily what is optimal for an extended life of the vehicle. (In fact, it's in their interests for a car to "fail early" - so you go and buy another one, rather than keep it 25 years!!). What 'sounds best' to a new buyer, 3,000 mile / 6 month changes, or 10,000 mile / annual changes? Most experienced mechanics will advise oil changes at HALF the manufacturers recommended distance.
Don't go 10k
@@bertblue9683 A lot of modern cars will be dangerously low on oil by 10k, in addition to the oil being full of fuel and contaminants by them. Unless someone drives 90% on the interstate sitting on cruise control 200 miles a day, 10k just isn't a great idea.
This is the most logical explanation on the topic I’ve seen.
Engine longevity & wear/tear (as well as carbon sludge accumulation) also depends on how the vehicle was driven, whether top tier fuel was used & even whether or not engine uses at least some partial port-injection instead of 100% direct-injection (aka likely carbon sludge magnet). Lots of long, open highway miles, or mostly short trips and/or city-driving stop/go traffic miles can each have a lot of impact on engine health.
@@DaveP-uv1ml it's less about pressure and more about air velocity and temperature. The air is moving fast enough and hot enough to burn off the carbon deposits at those higher RPMs
@@DaveP-uv1ml I would mostly be repeating myself here.. a carbon deposit is not fully oxidized carbon, fully oxidized carbon is CO2, which is a gas.
a good, hand-built motor should last 500K minumum, but you'll have to build it yourself if want to do it affordably.
My typical oil changes consist of 3000 mile or 3 months for good conventional oils.
4000-5000 miles or 6 months with good synthetic oils. I’ve been a heavy line tech with Ford for 15 years and worked at independent garages for 14 years……have seen a lot of damage from people not changing their oils frequently enough….typically it was lack of proper oil changes or lack of oil that caused 90% of all my work concerning internal problems….even repeatedly changed engines in customers vehicles for not changing the oil again after the first engine replacement …..some people just never learn.
Nailed it! 👍
What if a garage put 5w30 in a Ford engine that called for 5w20?
@@motleydude73 Specs on my VZ Holden are 5w30 or 10w30.

Thanks David. I love this topic. Really appreciate your views as well as a few others like carcarenut, fordbossme, and motoroilgeek who all say similar things. 6 months and 5K is the most i will do if I'm doing lots of highway driving.
Thank you, David. Your recommendations for oil change intervals are good reminders for all of us that doing proper maintenance is the best way keep your car running in top shape. I follow AMD, AKA The Car Care Nut, and watched almost every video. His technical reviews are among the best. From what I have seen, frequent oil changes can prevent castrophic failure no matter how long you plan to keep it.
As a mechanic for over 35 years, I agree 1000% with what you said. Spot on.
Thank you David. Much appreciated.
These oil topics are very essential. It is also good when opinions are backed up practically and scientifically. If people have good oil change and car maintenance culture overall, the vehicle will have more potential to run longer without causing super expensive repairs due to oil burning issues and end up on the junkyards as a result of it. Thanks
A lesson I learned the hard way myself.
Changing the oil at HALF the manufacturers recommendation (i.e. twice as often) is still much, MUCH cheaper than a rebuild or new engine - and will typically PREVENT the problems that require a rebuild or new engine.
Manufacturers extend the service interval as a sales pitch (looks cheaper and less inconvenient to the buyer), and have NO interest in keeping your car healthy past warranty - if it kept running fine for 25 years, you wouldn't buy another one....
@@OhSoddit So much true!
@@motleydude73don't be a troll, you missed the whole point of this video.If you are comfortable with rank/criteria 3 then go for it. Don't spew your "absolute nonsense" crap here.
Another thing to keep on top of is cooling system maintenance. With many if not most modern engines one overheating incident is all it takes to cause major and expensive damage.
Gone are the days when you could just let it cool down, chuck some water in the radiator and all is well.
yes, eventually antifreeze loses it's corrosion preventing capabilities. My F150 is now using a different coolant than what was originally in it from factory.
only if you use the right coolant and water- the interval is 100K on newer cars now.
Excellent summary and sound advice. Thank you
David,
Excellent video and your time and effort to make it is most appreciated. I need to ask a question.
I recently purchased my 11th Honda, in this case, a 2024 Honda CRV Hybrid Touring model. I live in Saskatoon Saskatchewan and get really cold winters and very hot summers. Having purchased the vehicle at the end of October 2023, we had to endure a brutal December. While I park underground in heated parking, I still need to venture outside in those temperatures, park it, and leave it sit for several hours, before restarting to drive it home. The CRV has active grill shutters that assist with getting the engine up to temperature as quickly as possible, in addition to giving me cabin heat, even though the vehicle operates in battery only mode at times.
My question is, should I trust the Honda Maintenance minder or go with my gut and change it more often. My concern is that the number of on/off cycles of the hybrid system means that I am more likely to not have the engine up to operating temperature for long enough periods of time to purge the crankcase of unwanted blowby and contaminants.
I would really appreciate your thoughts on this question. As others have said, the cheapest engine is really expensive, however the most expensive engine oil is cheap.
Thank you.
Hi David. Excellent simple explanation with your three categories. My dealer in Toronto recommends a 8000 K interval. I alter this by changing oil and filter myself at the 4K mark. Makes it easy to remember. I always use synthetic primarily as it is easier on the engine for cold winter starting.
Thanks for the video! I just have my 2023 GX460 serviced for first oil change from the dealer. They told me to go back for the next service after 16000 kilometres. I was shocked. I guess I will go back to the oil change for another 8000 kilometres.
Dealers typically follow manufacturers recommendations. Better if possible to learn to do yourself, then you make that call. The manufacturer makes their cash selling new cars.
@@RJ2878 Or take your vehicle to an independent shop if you can't properly dispose of the old oil. And, at an independent shop, you can ask them to use specific oil, whereas a dealer or an oil change shop will buy whatever the cheapest oil is (AMD from Car Care Nut surprised me when he said even the dealerships buy the cheap stuff and don't necessarily use their brand specific oil.)
I'll second the opinion for a "learn to do it yourself" (IF POSSIBLE). I have permanent partial disability (leg) and I can still do it no problem. I have a 2006 Holden VZ. If I'd KNOWN just how easy it is to do when I bought it, I'd have ALWAYS done it myself!! (For the Holden VZ, you don't even need to raise / jack the vehicle (can reach the sump plug with a socket wrench without ever being truly "under" the car), and the oil filter is easily reached from above (under the bonnet)). It took me 10 mins to watch a 10 minute "how to" video on youtube, and about 10 minutes to do the actual oil & filter change. Now obviously this depends on "your vehicle" / design as to how easy it is (or isn't), but if you CAN do it you'll most certainly be better off. Even if you need to buy any tools for this purpose, you'll soon recoup the cost in savings from dealer charges (hint, wait until auto stores have a "discount / sale" on oil or filters, and buy them CHEAP even before you need to do a change). If none of this is possible, I'd still recommend you locate and MARK the oil filter in your car (so you can be sure it's a different one when you pick your car up) - too many dealers have been caught out NOT doing the work they charge the customers for (and the "quick lube" places are even more shady). My car has "issues" at 220,000 km's (potentially facing a complete engine rebuild), I've been told by multiple mechanics if I'd had the oil changed at HALF the manufacturers recommended 15,000 km, none of those issues would have happened (I went 50,000 km's without a change and now it's "sludged"). Oh, and if you do stick with dealer service (I've had bad experiences), INSIST they change the oil FILTER as well - not "just the oil".
You need to ave proof of a professional doing the oil and filter changes re warranty.
You can insist that the dealer do it "in between" their recommended service points if you are paying for it.
Then there is no problem...
they have changed the oil and filter...you have the receipts.
If they do it as part of the service free re the warranty then they can do the next change for free at their stipulated 16k...you've done it at 8k...
You get it done and pay for it at 24k
They do it free at 32k etc.
They can't argue with it....
@@JohnSmith-yv6eq I thought that there was a law that said you could do the oil changes yourself - but keep the receipts. Maybe I'm wrong. Or maybe I'm thinking of the part where you do not have to take your vehicle to the dealer for service during your warranty, you can take it to your favorite private shop.
If you are driving stop and go suggest changing every 3000 miles. Highway driving 40 miles or more a day every 5000 miles. 😊
Thanks David for your expertise. I change my oil and oil filter in my Toyota at 5,000 miles.
You should be changing the oil in your Tesla every 1k if you want it to last. 5K is far too long for a Tesla!
@@noonyab3780 I don’t have a Tesla. And Tesla suck. I drive Toyota, the best.
This is a really great video, alot of people guve their 2 cents without really giving any weight to what a person does with their car. I've got a 23 IS500 that I've already changed twice and it's only got 4000kms on it. Now that it's broken in, I don't plan on ever going longer than 5000kms. I plan on keeping this car basically forever as It might be the last if it's kind. I also have a highlander, which I plan on keeping 4-8 years. I change that between 8-10 thousand kms. I'm using amsoil in both cars.
You know, you touched on a point which will become more poignant in the coming years. And that is the possible scarcity of vehicles with ICEs. I am holding onto mine like they’re gold (they might be soon), and maintaining them to the highest degree. Plus, I’m tired of spending 50+k for a set of wheels.
@bobhawkins3387 ya, I agree, I don't know what the future holds, but I think now more than ever, maintaining your ice's engine for the long haul is more important than ever.
the brand is pretty well irrelevant !I buy the prettiest can..yelloow is good.Weights arent nearly as important as people think!THERE IS so much " mechanical mythology" involving oil!ONE GUY TOLD me mixing weights was like putting half inch marbles in with 1 inch marbles..the half inch will never share the load!!!

I learned at a young age oil is supposed to stay clean and filters are supposed to get dirty and be changed. The problem is the only filters that clean oil are depth bypass filters. All after market. I have a Australian Jackmaster Classic on the Pontiac Torrent. The other engines and transmissions use Motor Guards. Gulf Coast juniors and The flat head Ford V8 canister filter on the Ford diesel tractor. The Motor Guard on the old Ford f250 390 is almost 60 years old. I have 2 older than dirt Frantzs that I will put on a lawn mower. They need new gaskets. You guys are suckers. LOL.
Thank you David! Great information.
Thank you for this sir, I'm about to get a new/used car and want to keep it at least 10 years and this really helps me to know what pace to keep with maintaining it, I appreciate it
2017 RAV4 with mostly highway miles with a road warrior job. Full synthetic, the oil didn't even start getting dirty until 6,000 miles. I added half cup of Seafoam or Marvel Mystery to the crankcase the day before oil change and made sure it was warmed up fully. It is my suspicion that the sludge buildup in/on the piston oil wiper rings are what cause these engines to fail prematurely and start burning oil. As it was mostly highway miles, I usually changed oil at 9k-11k intervals. Call me crazy, but 205,000 miles currently and no oil burning issues. Toyota filters from dealer, oil is not black...maybe dark brown before changing. YMMV but I'm very happy with this vehicle.
I think you are the wisest man not to do unnecessary frequent oil changes. Really crazy are those who change every 3000miles.
I have a 2020 Rav 4 with the 2.5 liter. I been doing the Mystery Marvel right in oil. Same thing. Oil looks clean at 5000 to 6000. I am using Mobil 1. 0W-16 weight with the high end Fram filter. I do notice that at 74,000 miles when you punch it in Eco mode it will redline like the transmission is stuck in 5 or 6th gear. I believe these have an 8 speed auto transmission. I have feeling that its not good on these motors to run right up to 6200 rpm. Creates a ton of heat. I wonder if that is why these engines fail at lower mileage? The Mobil one is rated for 10,000 miles. I have been doing it at 7500 miles.
You listen to to many videos and have a false idea of what's in your pan, if you change oil regularly there is NO CRAP in your pan
@@sawmanbigtreeslayer2360 I'm also 2022 Rav4 2.5L 8AT, I don't drive too much, so I usually change once a year.
2012 Hyundai Elantra 1.8 just turned 500K original engine , only used Amsoil top tier oil and Amsoil filter changed it every 11-12K it now uses two quarts between changes , no complaints.
That's awesome. Wonder if it's valve seals or rings, amazing oil.
In the early 80s Amsoil had a very good bypass filter. They had Bobby Unser saying this oil change is forever. At the time I was using Amsoil 10 40 with a Frantz oil cleaner. I quit draining oil routinely in 1963. I believe the Amsoil bypass filter was better than what they have now and too expensive.
Sure, the oil manufacturers certify their oil to last 10,000-20,000 miles depending on product, and they make high mileage filters, but I change my oil every 13 seconds just in case.
This proves a point I keep mentioning to friends & family. You have to know when to trust the owners manual and when not to.
Also, everyone forgets about transmission/differential/transfer case fluids too. This gentleman's drain intervals applies to those fluids too!!!
Need a transmission oil change interval video. Interview an Aisin transmission engineer!
Agreed, we mainly just hear people harp on engine oil
Agree too .
Since mine are over 10 yrs old ,
I do trans and gear oil change every 50k km.
That is after 250k mileage .
I wonder , is this "good" interval ?
Hint: Use Factory oil (less problems w/Asian - Euro transmissions), an independent shop utilizes that strategy. Been a client of this shop for 28 yrs.
Spent 20 yrs as a auto tech/machinist at a much earlier portion of my life.
About the first thing I do when I buy a car is put a good filter on the engine and transmission. Then I need a quart of new oil added. Im wondering why the Pontiac calls for Asian fluid. It has a Toyota transmission. Have to crawl under the car to get to the dipstick. They dont make Motor Guard oil cleaners now. Had to modify a M 30 compressed air filter. The 3.4 engine has a Australian Jackmaster Classic. I dont believe in allowing lubricants to get dirty then draining them.
@AutomotivePress: Excellent information, thank you! Can you do a video like this on transmission fluid, differential fluid, transfer case, etc?
EDIT: do these recommendations apply to turbocharged and direct injection?
it its turbo change oil evey 1,000 miles and if you want to play it safe then change the oil every 500 miles
I concur 100% with these recommendations. This confirms exactly the same recommendations from our Chief Shop Mechanic at one of my old Honda Dealerships. And Honda has built more engines that any other manufacturer.
Thank you, sir.👍
I get my oil changed every 6-months because I usually only go out driving twice per week & only drive about 3200-3400 miles total per year. So my oil is getting changed every 1600-1700 miles. 😝 Probably overkill, but its not breaking the bank to change the oil/filter twice per year.
You're a good person... Much respect.....
Can I buy your used car?
I'm a low annual mileage driver. I bought my 2014 Subaru Outback new, and I've put 46,000 miles on it in ten years, and I've put about 1,800 miles on it in the last six months. The oil looks dirty at 1,800 miles compared to my Lexus which always looks clean at the 6 month oil change interval. I use Wix XP filters and Mobil One on each vehicle.
Neither car has been to a dealer except for warranty work. I do my own oil changes and maintenance, and by the way, I'm 76 years old....still crawling under the cars. 🙂
Driving habits, driving conditions (Highway or city), climate, driving usage (off road, tow, commercial...etc), age of vehicle are all important factors missed here, with respect. I run a showroom condition 2015 AWD MDX in 🇨🇦 with 120,000km's on it. It's cold here and I do city driving mainly, I run full synthetic oil. The Acura maintenance minder is pretty advanced (It monitors many items) and I trust it. It kicks in at about 6,000miles (9,500km) and that's in line with the owners manual and what I believe personally.
I'm 100 percent on board with your advice.
Hi David.
Thank you very much for providing such a useful and comprehensive clip. Can I ask you one question please?
I have a Honda crv 2007 petrol 2.0 automatic with 126000 kilometres on the clock. I am from Romania, and over here we have in the summer around 30 degrees and in the winter reaches to about - 30 degrees. I was thinking to use 5w30 in the summer and 0W20 in the winter. Acording to your advice I should use thicker engine oil in the summer and thiner in the winter. Do you recon that 5w30 for summer and 0w20 for winter is the best option?
Thank you in advance for your help.
Every six months since mine sits in the garage most of the time. I only drive a few thousand miles a year living in Chicago.
But you drive in snow and rain and salt on the roads...
I had a truck that only got used 4-5 thousand miles a year and I would change it once per year with synthetic. Ran like new 17 years later when I sold it. Oil really doesn't go bad sitting in the crank unless you take a lot of short trips and moisture builds up.
Once before winter. Once after winter.
In the good old days, when cars and oil were both crap, it made sense to change oil and filter often. Cars and oil are both much better now. I bought a new Acura in 2006. Acura said 10,000 miles on conventional oil and 20,000 miles on the filter. I changed synthetic oil and filter every 10,000 miles. I sold it last fall with 223,000 miles on it. Oil analysis was fine. Performance was perfect. I never added a drop of oil. EPA estimate was 27-34 MPG when new, but I was still getting 35-37 MPG. Just how much better off would I be if I changed the oil over three times as often?
Agree. I've used Amsoil signature series which requires once per yr or 25,000 miles. I"ve put over 250,000 miles on it without a hiccup. Car is over 20 yrs old...still gets 38mpg highway..and a Toyota.
You wouldn't be any better off, kudos to you for doing it right. But someone with that same Acura who lives in a very cold climate, makes mostly short trips, drives with a lead food, uses low quality gas and cheap oil & filters, will probably never need to do oil changes because they'll be constantly topping off with fresh oil as their engine burns through it. This is what people don't get and why this debate continues to rage on. How quickly your oil gets contaminated and breaks down is CONDITIONAL. It's not set in stone.
Yeah.. but back in the old days.. we could afford a vehicle. 😅😂
Same here, but these rules of thumb are not vehicle, driving or environment specific. Certain cars will do fine with 10,000 oil changes if you live in the right area and drive lets say 50 miles to work each way. I have an Acura myself with around 150k miles on it and it still runs like new, and I change the oil every 10k miles with full synthetic oil.
But, that car was driven for hundreds of miles at a time on the highway, and it was in a relatively mild climate. If it was used for a lot of local short trips, the oil change interval would be much better at 5k miles...
The EPA mandated pushing the longer period to cut down on toxic waste. Manufacturers would prefer it more often.
I just got a new 2023 GX460 and love it.
Do you recommend an oil change at 1000 miles as part of the break-in process?
I have a big Toyota dealer 3 miles away while the Lexus dealer is 30 miles away so less convenient. Is there any reason to NOT use the Toyota dealer for a simple 1000 mile oil change. I will go to the Lexus dealer for the 5000 and 10,000 mile services of course, Thanks
Hey David, great channel car Care nut and I just came across another good one motor oil geek....I notice a lot of these guys go away from the manual when talking about doing a first oil change...1200 miles or roughly 2k kms...what are your thoughts on that and is there a special new oil from the factory that we should keep in there for longer?
When I purchased my IROC (305) back in '88, I decided that I would change the oil & filter every roughly 1.5kmiles. I have done so for 35yrs with the only change being that I switched to synthetic about 7 years ago.
So every 6 months or every 12 months
(Sunday good weather summer cruiser?)
it weird to me when people say it's a waste of money you can never go wrong changing the oil plus oil changes are cheaper than a motor
It'd be nice for that beaut to be ran on the highway every now and again to keep it exercised 👍🏽😏
Its hard to believe someone would be ignorant enough to drain oil every 3.000 miles. You can find filters that clean oil for less than 300 bucks. My oldest bypass filter is almost 60 years old and cost me about 30 bucks. My Australian Jackmaster Classic has already paid for itself. Gave up the oil change racket in 1963 with a Frantz oil cleaner and Standard Delo 30W.
Good video, thanks for clarifying the time interval regardless of mileage. But what if you take many short trips (2.2 miles, 4 times a week)? Should the time interval decrease to maybe 4 months?
With good warm weather approaching you should just buy bicycle, how long would a 2 mile trip take? ok when its raining or snowing, just drive, but if its nice out, why not give the bike a go?
I would find some time once every week or so to take it on the highway for 30 minutes. Too many short trips cause a lot of problems, and you can mitigate that by getting your vehicle up to operating temperature for extended periods.
There two main reasons I dont need to drain the oil. I have a oil filter that cleans oil and I drive far enough at normal oil temperature for the PCV to do its job.
Thank you, I am a do it yourselfer and I have great interest in these topics.
‘’I bought a new ‘’2023 TRD OFF ROAD PREM’’….I had the oil 1st oil changed @ 1000 miles….next oil change will be at 5000.00 ..got underneath my 4 runner..1st.

I will tell you this truck rides fantastic. ‘’Thank you …for all the reviews and videos on these amazing automobiles. Thanks. God Bless and many prayers to family and friends.
Don’t most new car engines come with a special factory oil with additives in it that help keep the engine lasting and help with break-in? Most mechanics I hear this information and that’s why it’s recommended for most new cars to not change the oil until 6000-7500 miles at least?
Depends a lot on the engine and also driving.
The family MB needs oil change every 4 months 😭 due to fuel dilution
Have been driving for over 20 years, always change engine oil and filter when around 10k km. Using well-known brand fully synthetic for all my cars except 1 using semi synthetic. But that 1 car will have an oil change interval at 7000km. No major problem so far. Own several cars, each been driving for more than 5 years.
Thanks for these informative recommendations. I have in the past used the 5k miles because it was easy to remember when my vehicle's oil and filter needed changing. New vehicles like my 2016 Ram diesel 2500 and others have an oil percentage of life left. What is your recommendation based on the percentage? I just had mine done with 40% remaining. I was at the dealer, and it did cost $192.00 I am not sure of the elapsed mileage.
I love this piece of advice. I'm criteria A and I currently have 2 cars. Both use synthetic oil and both get oil and filter change twice a year independently of mileage. I typically drive between 3000 and 4000 every semester. I organize myself and I perform my own oil change mid-year and I take to the dealership once a year so that they plug it in and lube doors/etc. Greetings from Argentina! Nacho.
That's exactly what I do the criteria a weather I own the vehicle five or fifty years I always change the oil within a six month period!
Run full synthetic. Change ever 5,000 miles. You can't go wrong.
Great video. I’ve been doing oil changes on my C63 about every 4,000 to 5,000 miles at least every 6 months to a year.
Super video, thanks.
If OEM milage intervals in your manual are based on OEM oil, and that OEM oil is already a full synthetic, I'd argue it's best not to grant any sort of leeway just because you're getting full synthetic.
I typically hit the 6 months point long before I hit the milage anyway, so I'm saying that with no skin in the game 🤣
Many owners manuals also list a "standard usage" and "heavy usage" maintenance schedule. With standard being in the 10-12k miles/1yr, and heavy being half of that. And it's very easy to fall into the heavy usage category. Trying to convince my family they fully meet the criteria for heavy usage has been an uphill battle, even though they want to keep their cars to infinity and beyond.
Interesting. I own a 2005 Honda CR-V with 92,895 miles. I just had my oil and filter changed at my local Honda dealership earlier today. They recommended I get my next oil change in 5 months or when I drive another 5,000 miles. Their recommendation and my expectation for this car lined up with what you discussed in your video. Your breakdown was appreciated. Thank you.
The 2.4L used in CR-V is one of the worst Honda engine and every mechanic knows they will burn oil if the owner will go more 6000 miles/10,000 km on oil changes. While Toyota fixed the oil consumption issues in their 2.4L, by updating pistons and rings, Honda did pretty much nothing. I changed/rebuild dozens of those engines, at least 3-4 every year. In fact there's a one waiting for us this month - it will get low mileage engine sourced from Japan, since it cost the same head/valve job and installing new rings.
The same goes for automatic transmissions - they hold less fluid and require more frequent ATF changes. 50k km is the norm.
My recommendation max 5k miles OCI on synthetic oil. And if you live in southern US, 5W-30 since it boiling temp is usually higher than 5w-20 oils and doesn't get baked as easy in your oil control rings.
@@pliedtka Even more reason to stick to what the dealership recommended
except that older cars/engines benefit from MORE frequent oil changes than standard/original. Furthermore, increasingly over past 20 yrs of the lengthened OCI's, mounting evidence has risen of engines becoming damaged before they were expected to. E.g. in toyota or honda engines, not lasting anywhere near as long as other same engines do when oil changed more frequently and closer to original classic intervals of 3-4K if car is daily driver. Out of my dozens of high-caliber mechanics, they also say more frequent is better in most cases, partly bcuz various factors of engine systems in past 25 years, as well as reduced quality of engines vs 35 years ago, warrants more frequent OC's if u want the engine to last the often-possible extremely high mileages or high-years that Honda and Toyota can. It's cheap insurance that's for sure.
You can go a year if you don't hit the 5000.
I want to keep my car 20 year but Honda recommend to change oïl once a year or when you see 15% on youre dash, what do you think ?
I was changing my oil and drained out the oil into my oil catch pan and thought I had a new oil filter, but I don't so I have to wait for an oil filter to come in about 3 days.
So is it okay to let my vehicle sit up without putting oil in while I wait for the new filter? Or should I put the fresh oil in and then drain it back out when the new filter comes?
By the way, I haven't taken the old oil filter off yet since I didn't want to have that area with nothing on it.
I find remembering to do the oil change is critical. I've got five cars in my "family fleet". The cost of oil for the car is a fraction of the cost of the fuel I put in a car, it doesn't hurt I shop for oil on sale, get good quality oil filters inexpensively and change the oil myself. All that said, I like an interval of 3,333 miles. So, my entire fleet gets oil changes when the odometer ends in 3,333 miles, 6,666 miles and 9,999 (10K) miles. They're all on the same schedule, so I can tell at a glance when I'm due for an oil change on any of the cars I'm responsible for.
At first, I thought this sounded ridiculous. But the more I think about it, it’s awesome! I’m definitely starting this
When changing oil at 3,000 mi was the standard, it was easy to just add the first two numbers on your odometer and if it was divisible by 3, it was time to change your oil. 3000 3 + 0. 42,000 4+2 96,000 9+6
David, do your recommendations change for PHEVs like the RV4 Prime? Especially, if the majority of the miles were in EV mode?
This is a good question. I have done around 22k miles in my Toyota Yaris cross, serviced with oil change at 10k and 20k. Hybrid EV mode kicks in 50% of the time for most of my journeys. This means my engine has been serviced at 5k and 10k miles right?
Yup, I’m wondering the same. I drive on my prime mostly on EV - 98% of the time lol so I assume I wouldn’t get oil change as often maybe 10k - 15k miles?
Probably worth lab testing to get a good trend and interval going
Great video and information. Thank you for sharing. 👍
Very helpful video 👍
It would be nice to add an addional category for those people that don't drive very much and make lots of short trips. They need to be changing their oil more often or yearly or max every two years, but it is hard to convince some of them.
Almost always keep my vehicles for 10+ years. Growing up in West Texas and New Mexico it was super important to keep the oil and filters fresh. The air filter as well and the box vacuumed out.
A follow up on radiator care would be welcomed.
Engines seem to have come full circle in their operation. It used to be important to warmup a carbureted engine and then it became less so with direct injection. Now with all the turbochargers it’s back to a warmup stage before pulling out.
Warming up in the driveway has always been bad for engines. It prolongs the time running cold and a rich mixture washes oil off the bore. It’s best to get it warm as fast as possible and that means driving gently as soon as you start it and back out of your driveway.
It needs 5 seconds for oil pressure to stabilise and get to all parts - that’s it.
Obviously don’t beat on it until the oil (not coolant) temperature is about 50 degrees Celsius
@@froggy0162 bs
@@mikeprice8307A well argued and thoughtful response. I especially enjoyed your technical analysis and deep understanding of the engineering involved. Well played sir.
West Texas/New Mexico. My family had a farm 46 miles south of Portales for a few years. Dry-land, no well. Then moved 35 miles northeast of Clovis. Irrigation! But, centrifugal filtration along with the oil bath for the final stage was the going thing. People who've never had to dig the oily dirt from the bottom of an oil bath would not believe how much accumulates. And not just farm tractors. My '55 Pontiac also had the oil bath and you couldn't run too long without maintaining it. After I got something with a modern filter, it didn't take long to start dragging mom's vacuum cleaner out to the garage to clean out the box!
@@froggy0162 You can't drive gently from where I live. After the first 0.2 miles, it is up a steep grade with lots of turbo boost. Fortunately, my car is kept in the garage so it is at least 50F when I start it up.
Thank you for sharing this information.
As a 'European' i love watching this content(and the discussion) as over here, annual maintenance - which is basically an oil/filter change plus look over on a 2 post - is the norm.
A lot of European cars have variable servicing which push frequencies up to 2 yearly/20,000 miles. Really!
Could this be because 80+% cars here are leased and the first owner will be chopping îr in after 3 years, so who cares about longevity?
I would say that that tribology is so much more nuanced than given in this video. API standards require oils to meet minimum ASTM test criteria AFTER many hours of simulated usage:
Heat - gross/integrated operating temperature, heat cycling - base oil & additive oxidation;
wear rate;
dirty carrying capability;
lubricity (fuel dilution doesn't help here);
water exposure
Etc etc
So depending on the use case, 100 hours or 1000 hours could see your oil dipping below the minimum requirements and hence not protecting your engine.
Are you a fleet, where extending intervals by 3000 miles could save you 10s of thousands? Or is it your one car that gets you to work all day and you can dispose of the oil for free?
The manufacturer recommendation will find those common failure points where cleanliness is critical. AMD just repaired a Tundra with a sticking timing chain tensioner.
That was a great video. I'm 3 hours from Amd's shop and only have him service my cars.
How about some BMWs or Audis - not only chains are problematic but also labour intensive. Engines are very expensive for them, oil and chains relatively cheap.
So the moral of the story is DO NOT BUY LEASED VEHICLES EVER!!!!
I agree it would be better to buy new, instead of lease. But I have been buying off lease CPO Toyota and Lexus because of the lower cost and service history. Although only the manufacture's oil change interval was followed (A) early in it's life, I change oil with (B). Both of these vehicles. 2014 Camry (150K miles), 2008 Lexus ES350 (125K miles) consume very little oil and run great.
I would add a caveat that buying a leased vehicle or or a "program vehicle"/ demo or a used vehicle that is no older than three years can be fine, provided that the Carfax indicated proper oil changes and maintenance. In my life, I have never been stuck with a vehicle that was not cared for properly. Additionally, buying new does NOT guarantee success. As an example, I have experienced a Coyote engine that needed a quart about every 1,500 miles; according to the manufacturer, that usage is normal. I had a second Coyote in a different truck that never used oil during an entire oil change interval. I also had a 305 cu. in. that, after the 12k warranty was up, showed 2 adjacent cylinders with wet spark plugs.
I have a 2023 Acura tlx type s. Just reached 15k miles…the car is so much fun to drive. I change my oil every 2500 miles. I really love my car, it brings me a lot of joy so I go all out on maintaining her.
thank you for the video and it was very informative. I was wondering about additives called "Zinc" is it good for your engine and if so, do you have a brand of oil that has more Zinc than other? Also, does Zinc makes your catalyst Clog? Please Advise. Thank you
Hi David… First of all, Thank you for your video. Very informative. I too follow AMD @ Car care Nut. I purchased a 2024 Toyota Corolla and I’m planning to do a break-in oil change at 1k. The recommend oil is 0w8 oil and is very difficult to find and very expensive. Would it be possible to substitute 0w8 oil with 0w16 and would that damage the engine? 0w8 oil is a very controversial subject and would really like to hear your opinion on this oil.
I remember when 5W-30 was 'controversial'.
Go to non cafe country you'll be surprised
My 79 Ford diesel tractor has a sticker on the engine that says I can use 10 30 or 10 40 but for extreme high temperature use 30 weight. Last summer I put heavy duty off road 30 weight in it. The first cold morning I pulled the dipstick. The oil was too thick to circulate. I went and got 15W 40 diesel rated conventional oil. I can order Chevron Delo Diesel 30W. Getting hard to find.Started in 1963 with a Frantz oil cleaner and Delo 30W that was winter grade. I normally dont drain oil. The tractor is well equipped with toilet paper filters.
took my new 2023 Lexus GX 460 in for first oil change at 800 miles. The dealership actually tried to talk be out of doing it so soon but I insisted. I wanted that first oil change early given that will be the period of time where the most wear takes place. I did note that the oil capacity for the 0W20 oil is almost 9 quarts. I am guessing they are trying to use the lighter oil and more of it to lubricate the engine. What is your opinion on the 0W20 oil. it sure seems light.
A few days ago, I bought a new 2023 Lexus GX 460 and it will have its first oil and filter change between 800 to 1000 miles. Car Care Nut TH-camr bought a new GX 460 and did a 1000-mile oil and filter change on his GX. He showed all the metal particles trapped in the oil filter that's common to see from a new engine.
@@thedetective8150 urban myth!!!! The oil filter catches the little baby small small metal particles that the engine puts off 500 to 1,000 miles. It's dosent hurt to change it but it's does waste money and time. There is no scientific proof to the early new car oil change.
What about specific Nissan ESTER oil. Whats the difference than regular engine oil and any other alternatives for cheap ester oil 5w-30 at regular stores? Thanks!
Hello thanks a lot for your videos please i am asking is the hot weather effect the oil my car is lc300 V35A
What about the Honda engine oil life computation displayed on the dash?
i would follow that. It was designed by the manufacturers engineers. I have a company truck in which i do just that, go by the computer notifying me of an oil change. About every 12K km. We keep the trucks for about 5 years in which the odometer shows approx 250K km.
I can’t remember the last time I saw a vehicle replaced because the engine was worn out. Almost always it’s the car that falls apart around the engine. The transmission fails, all the accessories start failing or the body rusts out, or the cost of repair exceeds the value of the car. Seldomly do I see and engine needing replacement.
Go to a Kia/Hyundai dealership and you'll love the blown engines lining up for new engines. 😊
I hinted I would like to buy a guys Toyota Camry that belonged to his wife that is in a nursing home. He said its going to his daughter. Her Camry has over 500.000 miles on it and is starting to give her trouble. He said I have a nice Hyundai turbo 4 that threw a rod and is being repaired under warranty. Would you be interested in it.
Very good advice. Thanks.
Hi, great video. Can you tell me what you think about the white milky ceramic oil? Any good for a thp 1.6 200hp. I hear it is realy good for the anti friction and high temps but most importantly i just would like to know if it helps me to keep the car for as long as possible. Love my car. Fought hard for ir and it has a lot of emotional value to me for a lot of other reasons. 😂 ❤
I got a 2013 Lexus ES in 2018, I noticed right away that letting the oil go 10k, even the good Mobil 1 full synthetic, it came out so so black, I thought, this can’t be right. After that I started doing 5k intervals but now that it has 115k, I’m doing 3k changes.
My LX has 243k miles and I baby it with oil changes every 2k mostly because it’s driven off road almost as much as it’s driven on road.
It's just soot, in fact, it's good that it's in the oil and not depositing in the engine, that's one of the many benefits of modern oils. You really don't give modern oil enough credit.
@@TheRealSykxexactly!
The oil being "black" is more than likely from the cleaning from the oil, as synthetic oil is detergent oil
At 250.000 miles without an oil change the Mobil 1 in the 84 Subaru looked new. At 65.000 miles the Walmart synthetic oil looks new in the Pontiac The Subaru had a Frantz oil cleaner. The Pontiac has a Australian Jackmaster Classic If the oil gets black in a gasoline engine you need a better oil filter. I expect the oil in my diesel tractor to be black. In the 60s it was common for the oil to be black in 2.000 miles. Install a bypass depth filter and the oil looked new if you used the right oil. Standard Delo 30W or 20W was beautiful when it was clean.
Criteria c does not appear to be ethical. The next buyer of the used vehicle will have to deal with the decisions of the first owner. Do unto others what you want others do to you. Criteria c is for those who do not care about the vehicle or others that will take over the vehicle.
100% nailed it, couldn't say it better.
Following the manufacturer's recommendation is unethical?
If so, it would be the manufacturer who would be unethical.
Hi. I have a 2023 Toyota 4Runner Limited. I live in The Bahamas so fuel options aren't as plentiful as they used to be OR like what you have in the US. I use Esso. I believe Rubis (aka Texaco) uses the same formula as Esso and Shell [allegedly] uses additives and their fuel is also colored blue.
My current mile reading is 175 since I bought the Runner new at 26 miles in the early part of August 2023. I did the obligatory "1,000-mile or one month service" in September 2023. I only drive the Runner once a week and use my daily (2001 Chevy Blazer) otherwise. The dealer had me scheduled to come in during the month of January but I didn't.
What're your thoughts on the schedule for oil changes, etc based on my limited driving of the Runner?
25 year old Honda Accord, oil and filter changed every 3,000 miles and it still runs perfectly.
Thanks David, awesome breakdown for each oil change criteria :) 100% true results for "criteria A" with a 2001 Camry replacing oil/filter every 3-5 K kms since new and now the car has almost 500 K kms and still runs like the day it was born 😀
just wow!
My 84 Subaru went 250.000 miles without an oil change If I changed the oil every 3.000 miles it would still have gone 250.000 miles. That car had a Frantz oil cleaner. It never saw dirty oil. The contamination was in the filter or thru the PCV.
What if you're a very, very low mileage driver? Like 1200 to 1500 miles per year (two or three days a week)? Do you still recommend every six months?
Once a year
Supposedly the oil loses its chemical magic with age and the heat and cold cycles. Oil changes are cheap and fast it wouldn't hurt to change it more often.
Great information!
Does your recommendation change for diesel cars/trucks?
The greatest video 📹 EVER!
Thank-you! You helped me SO-OOO-OO MUCH!
May Almighty God continue to Bless 🙏 you (and your family 👪) for all the things that you do!
❤
Could you show us the test data that support your recommendations? Thanks.
Test data? 🤣 He's got your test data hangin'.
He’s an engineer. he makes these engines.
@@Maynardd That's not data and he doesn't make any engines.
@@joevarga5982 just designed them, hence the word engineer. start looking up things on TH-cam like what happens to my engine if I don’t change my oil. The data has been available for literally decades. Don’t be ridiculous.
@@Maynardd What engines did he design? What oil testing programs has he performed? I ALREADY know what happens when you don't change your oil. Where did I say "Don't change your oil."?
Stop putting words in my mouth then attacking me for saying things that I didn't say, clown. You're the one who's being ridiculous.
Now answer my questions.
Great video. Great information. Thanks
Having spent 42 years in the automotive industry, 32 of those as a shop owner with employees, I agree with your general service interval assessment. Especially for those who don’t read their owners manual. The whole service interval thing has become such a contentious thing. The automotive manufacturers have fallen into the word game, making up and changing definitions. With the 10 and 15,000 mile service interval Almost No one falls into the normal service interval. The normal intervals consist of starting the vehicle in Temperate conditions, driving a short distance to the freeway. Driving at freeway speeds for an extended period and a short distance to your destination. No cold or hot start conditions, no extended, driving on surface streets to get to the freeway. No stop and go traffic, no heavy loads (including passengers) , no short trips, no mountainous, driving, no towing, etc. All that would be under severe conditions, which applies to most of us, that is a much shorter service interval. Also what people don’t understand is that there are other things in their owners manual that are supposed to be done before that 15,000 mile oil change, brake inspections, tire rotations , fluid checks etc. Having a service done at 5,000 miles intervals rather than 15,000 miles intervals can save you money. If you use 15,000 miles as an interval and your tires or brakes only have 6000 miles left, they will sell you tires and brakes before you need them. Not to mention any other issues like belts, leakage, lights etc. A vehicle is an investment you need to protect. On a different note, I love that guy who was arguing with you about oil analysis. At no point did he say he was taking a sample between oil services or what type of driving he does. I love the guys who say “ I do 15,000 miles between oil services, but I do 15,000 miles in two months. Back to the beginning, it’s not the miles but the type of driving. 😊😊
The bigger question I believe, is do you drive 3 miles to work every day or 30.
3000-4000 miles or every 6 months, as long as you do highway driving of 20-30 miles every week to burn dilution of oil by water and gasoline.
I use bypass depth filters on everything including lawn mowers. Even with filters that clean oil short trips in cold weather is a engine killer. In Idaho no problem I drove 36 miles one way to work. Years ago when I sold depth bypass filters I sent filters to placed like Norway and Northern Canada. Frantz at one time had a heater. I think it was a Alaska package. Kind of like a electric blanket. Not such a problem with modern synthetic oil.
The PCV cant do its job until the oil gets hot.
You are 1000 percent correct don't bother about such criticism
From engineering background could you also recommend the other systems albeit closed systems like the transfer, differential and transaxle. 2024 1794 4x4 OR CM Tundra HV. I did my 1st engine oil change and filter at 1500m. But will also change the systems in question at the 3k mile point along with the 2nd oil change.
Question: I have a bunch of cars that I don’t drive more than once or twice a year. How often should I change the oil in them? (High compression sports car engines running mobile 1)
Going off Blackstone UOAs I change my oil every 25,000 miles running Red Line (POE base) or Amsoil signature series (PAO base) heavy duty 15w40 and the 2 micron Amsoil bypass filtration system. At 25k it still has plenty TBN and anti wear additives left with minimal wear metals and fuel dilution. It probably would be safe to run 30k intervals but 25k gives me peace of mind. I’ll change the full flow filter every 12,500 miles. For that I use the Purolator Boss
i understand there can be varnish build up from long interval changes even though the TBN and wear additives are good
@@fitnesspoint2006 That’s a fair concern. I plan to pull the valve cover off soon at 80k and inspect. I’ll report back!
There is almost nothing in a modern engine large enough to be removed by a full flow filter. I have no way of measuring microns.The Australian Jackmaster Classic claims 1 micron. Motor Guard has always claimed submicronic. I believe Gulf Coast filters claims 1 micron. I have all of them in use. I gave up allowing oil to get dirty then draining it in 1963 with a Frantz oil cleaner. I normally dont drain oil.
@@ralphwood8818 interesting…you’re talking about bypass filters, correct?
Yes bypass toilet paper filters. Toilet paper is high quality cellulose. They are trying to hide the fact that they are toilet paper filters. Jackmaster puts a high quality roll of Australian toilet paper in a sock and charges 20 bucks for it. I use Great Value 1000 from Walmart in mine. Most use Scott 1000. People assume toilet paper comes apart in oil. It gets stronger in oil. I started with a Frantz in 1963. Went to the top loaders in the 80s. The Jackmaster needs a firm roll. It has no center tube. They depend on the 1 15/16 core seal at the bottom. All I have used is the classic. Not familiar with the Ultra or the bigger models. I sold Frantz Motor Guard and Gulf Coast filters years ago. Motor Guard only makes compressed air filters now. I think Gulf Coast filters only makes paper towel filters now. When I was selling Frantzs Gulf Coast filters had Frantz 3 stackers all over the Gulf of Mexico. At some point the Frantzs went out of production. We also lost the FAA approved AeroFrantz. In 1963 I was working in a full service Standard station. A Standard oil engineer told me to use a Frantz and Delo. Delo came in 20W and 30W. Couldnt use multi grade in a diesel.
