Out of curiosity, what is there to love exactly and what filters are you using? I know they have various mileage limits on oils as does Supertech. 5k, 10k and 20k What kind of vehicle, how many miles and what are your oil change intervals?
@Balticblue93 I used to use penzoil high mileage comventional on my then 2007 honda civic. Used to have to add a quart every week. After switching to costcos i only added oil once a month. Sold civic with 265k miles.
@@Balticblue93 other vehicles 2011 Acura MDX and 2015 Toyota Avalon. 5k miles intervals on all my vehicles. No oil loss. Mobil 1 filter for Honda Vehicles and OEM for Toyota.
Great video! You kept your oil analysis spreadsheet up throughout your detailed walk-through. Most other reviewers like more 'face time' and tend to rush through their presentations. I didn't have to pause the vid to absorb the info. Thank you, I'm headed to Cosco right now!
One thing to remember is that some oils, most often the ones with inferior base oil characteristics require more additives in order to meet the automotive specifications. It could be that the additive concentrations in the kirkland is higher due to this, but unless you run a FTIR analysis you can't really know for sure. Thanks for the informative video!
Very true sir. It’s very common with group 4 or 5 oils or the natural gas (GTL) base oils like pennzoil uses to use less additives as the base oil is better. Unfortunately the oil manufacturers don’t provide much information but I’m not aware of either oil using that base stock. There is a possibility Mobil 1 blends different base oils with group 3s to keep costs down.
You can check the MSDS for all oils although they don't have list proprietary additives if they are not hazardous, as is my understanding. But the MSDS will say if the oil is PAO synthetic in most cases.
Nice... too bad they don't make cars like they did back in the early 2000s. Folks need to change their oils every 3 to 5k, depending how you drive and the type of driving you do (in town or highway) Not 10k. That is usually about 2 engine oil changes a year. It's worth it. Espeically if you do it yourself ... get some car ramps (50 bucks)... and it is crazy easy, fast, and you can use the best oil and oil filter .... and you know it was done correctly.
Thank you sir I appreciate and have used oil analysis to set drain intervals and double-check that what I'm doing is still working. Also you are right on when you talk about the difference between group 3 synthetics and the true synthetic there is a difference 'full synthetic' does not equal 100% synthetic it is a marketing term
I stock up on the Costco oil when it goes on sale. Costco has a reputation to protect, that’s why their oil is of high quality, and their gasoline is top-tier.
I haven’t seen it go on sale here in California Costco’s yet. I’ll be sure to buy extra if it does lol. A few years ago the kirkland full synth 2 pack cost 30 bucks and now it’s 40.
I’ve seen it on sale more than twice a year, but I can understand why it might not go on sale in California as they don’t want to promote internal combustion engine use.
Excellent presentation. A few comments that you may take any way you like., I have been using Mobil 1 in my cars since 1976. I have not had a single oil related problem with any engine since that time. Before that I had a major brand nonsynthetic oil lose lubricity and destroy an engine in a Plymouth and another oil failure from sludge build up destroy an engine in a Ford. Then again I had an AMC six that ran over 300,000 miles with no problems on that same brand oil. When I sold it the engine was still solid. I used to change synthetic oil every 10,000 miles, but I have seen some engines so sensitive to things like film build up that I am now changing 5,000-mile intervals.
Sure. I've used mostly conventional and synthetic blends up until maybe a few years ago and have never had an oil related failure. There was , and is nothing remarkable about Mobil 1. If you get the warm fuzzies after installing it into your vehicles well then good for you. Just know that there is nothing superior about the so called holy Grail Mobil 1 . All you've been doing is paying more for advertising and a "reputation".
@@joeblowe7545 I agree that there is nothing about Mobil 1, that is better or worse than other synthetic oils. I was an AMC mechanic for years. I saw the insindes of many engines after only 100,000 miles on standard oils of the sixties and seventies. I have also torn down an AMC 258 six that had over 300,000 miles on it using Mobil 1. The difference was amazing. Cross hatching in the cylinders with no measurable wear. We miked the cams, lifters and rockers. Everything was still well in speck. There was no measurable wear on the bearings. I never saw an engine still in speck with much lower mileage running on conventional oils in the sixties and seventies. True conventional oils have improved a lot since then, but I will stick with synthetics from now on. BTW that engine had filter changes every 5,000 miles and full oil changes every 15,000 miles. Something I would never do in a modern engine. We ended up cleaning the engine really well and reassembling it, changing out only the piston rings, valves, gaskets and seals.. We also changed out the water pump for a newer type developed by AMC.
Thanks for doing the test. Very informative. I've been using the Kirkland oil now for years with great results as all my vehicles generally go to 250K miles or more. However, I change my oil every 5000 miles, not the manufacturer recommended 10K. Oil is cheap--engines are expensive. Especially if you use the cheaper high quality oil from Kirkland. I assume you ran oil to 10K miles to make for easy rounded up number test. But I would never recommend that change interval. The savings from prolonged oil intervals are peanuts to engine wear damage, particularly on turbo engines where the turbos spool at up to 30K RPMs and need oil to keep them cooled, thus degrading the oil faster. Just changed my neighbors oil on 2017 Honda CR-V and it was black because of the turbo even though it had only 6K miles on it.
Consider the fact that he had laboratory analysis done that showed active additive left and no consumption after 10k. I also change at ~5k but I have to admit there is no rational basis to recommend it to others.
@@lenlaskowski7374Trust the test but the analysis was done on a 2015 Toyota Corolla which is one of the most bullet proof motors ever made in the World by Toyota. Change your oil every 5k & don't listen to this guy. If you don't believe me watch The Car Care Nut a 25year certified Master Toyota Mechanic and he screams at the top of his lungs that the 10k recommendation is BS. I trust the guy who has seen and fixed hundreds of blown Toyota & Lexus motors due to oil changes being done every 10k..
Great info…thanks. My former brother-in-law was a petroleum engineer. He was of the mind that the oil you used (assuming appropriate API rating and viscosity grade) was far less important than ensuring regular/shorter oil change intervals, especially for cars with inherent sludge problems created by poor design (e.g., Chrysler 2.7) or more complex engines, such as engines with cylinder deactivation systems. He used to say that full synthetic oils were clearly superior to conventional oils, but unnecessary for most people unless their car maker specifically recommended/required it (e.g., any turbo engine). As he explained it, using synthetic oil was like putting six legs instead of four on the footstool in front of your favorite TV chair. You could do it and your stool would certainly be stronger...but it would just make your stool more expensive and it wasn’t going to make it last any longer.
Agree. It's not just the base oil breaking down, it's the additives that keep the oil healthy. Just look at the oil when you drain it. If its black and burnt you waited too long.
I did 15K oil changes in my 2011 Kia Sedona for years using Mobil 1. Never had an issue, always passed smog, and the engine looked clean when I did the valve cover gaskets close to 200K miles on the van. Modern synthetics are great.
maybe you can get away with that type of interval on a big naturally aspirated 6 cylinder engine, but on a turbo charged engine a 15K mile interval would destroy the engine by 100K miles...especially a 4 cylinder turbo
I have a 4 cy turbo 2.0 VW GTI. I change my oil every 3 to 5k. Closer to 3 than 5. Car has 103k on it... runs awesome. It a 2011, I am hoping to get at least another 100k on it.
my ex works for Chevron engine oil department, even she uses mobile1 and not their own company's top oil, she does analysis on her own car after each oil change as well
I had an uncle that worked for Mobil 1. They did a test where they ran an engine 100k miles .. 3k oil changes. They tore the engine down and it still had the wear marks on it... which means the engine had no wear on it. Crazy impressive. I use Mobil 1 European blend in my 2011 VW GTI. It has 103k on it. Drives great. No isses.
I have a 2010 Toyota Camry 2.5L four cylinder with a 6 Speed Manual. I drive about 400 miles a week back and forth to work all highway/interstate driving. Going between 70 to 80 mph everyday 5 days a week. I still change my oil at the 5,000 miles mark. I do about 3 to 5 oil changes a year. Thats between 15,000 to 20,000 miles a year. I've been using Castrol for many years and i recently switch to Kirkland 0W-20 due to price point and availability. Pretty good so far. Im currently on my 1st Kirkland bottle now in my Camry. I have over 260,000 miles on the clock and the car doesn't burn no oil.
I am a faithful Valvoline Full Synthetic person for my two 2005 Corollas.... I would use Kirkland oil though and have thought about it... It does have a great price point....
i like the valvoline oils as well, especially their full synthetic max life for high mileage engines. it literally stops small oil leaks and stopped my camrys puff of smoke at cold start up
True synthetic oils would cost a few hundred dollars a gallon. This is one of the first videos I have seen that actually gets this correct concerning PAO's and other "synthetic" oils. Just my two cents as a Tribologist. Two thumbs up and WELL DONE!!!
If you live in "The City" or an urban area, your type of driving qualifies as Severe Service; idling at traffic lights, stop and go, short trips, shutting the car off before it's been driven for 30 minutes. Keep that in mind when selecting your oil and determining change intervals.
How does this help us select oil? What you described is exactly my driving conditions, often just twice a day for kids school trip is 2 17 min sessions. My manual says 5W-30
@@NathanBrantleybasically with the type of driving you do, you should be changing your oil every 3-5 thousand miles. Now if you were driving a 100 miles a day to work and back on the highway, you could do 10,000 according to this guy.
Great posting and kirkland & M1 similarities may explain why only those two burned more in my subaru outback. Once I switched to pennzoil or castrol, the burning was less. Also will be getting those Blackstone analysis for our older porsche boxster, especially for metal.
I service multiple fleets and was at one point using Costco brand because of reviews. Things I noticed; the oil leaves behind a yellow tint residue on parts (head, covers, etc...) as it starts wearing, mobile one does not leave this residue. Also with Kirkland brand I noticed it causes gaskets to prematurely leak; seems like maybe the gaskets are hardening up faster than normal. Besides those two things it performed identical for the most part.
Another thing to consider is how long one leaves the oil to drip. We have 3 cars- 2021 Tacoma, 2021 Crosstrek, and a 2017 Jetta. The Crosstrek is done dripping in 10 minutes. The Tacoma is more like 30 minutes, and the Jetta takes 90+ minutes. Let all the drips get out of the crankcase, as you would be surprised how much oil volume a little drip can make! When I took my Taco to the dealership for a "Toyota Care" free oil change, they only had my truck back there for 13 minutes. That was the last time I let somebody else change my oil. I do my cars every 5k. Arguable I should probably change the jetta sooner than that since it is a turbo. I use Castro European oil in the Jetta, and Kirkland and Mobil one interchangeably in the Toyota and Subaru. (They are both 0W-20)
A lot of fuss over nothing. Let it drip for 10 minutes or so. Your cars will never know the difference. My brother once told me he let his oil drain over night!. Some OCD and maybe some insanity going on there.
@@joeblowe7545 Agree. I have an independent Honda garage do mine. They let it drip for about five minutes and cork her up. I have 270K on my 2005 Honda Pilot with 5K conventional oil changes. Probably going to get a 2020 Passport EXL with 17K on it.
Excellent. I have a 2006 Matrix (Corolla) 4WD with 223,000 miles and it runs perfect. Been using Kirkland 5w-30 for the last 100k miles and M1 (at $25/jug) before that with 5k OCI and OEM filter I recently bought 4 jugs for 68 bucks online. Vehicle used for ride share/delivery. I think I've saved over $4000 doing my own oil changes
You are correct on many things but some things I think need clarification. If you have a naturally aspirated engine and drive all highway miles, going 10K miles between oil changes shouldn't be unreasonable providing certain things are met. First Synthetic oil. Second (and possibly more importantly) using a high quality oil filter that can go at least 10K miles. If your oil filter gets used up at 5k miles, you will have another 5k miles where the filter does nothing. So the filter is important. All oils that follow their designated specification should be OK and then it is a matter of brand preference. A Dexos 1 oil is a Dexos 1 oil. However if you drive lots of city/stop and go driving and/or have a turbo engine with GDI, I think going over 5K miles is pushing it. With City v high driving, it isn't so much the mileage as it is the hours. You do 10 hours of high miles at 75 miles and hour v doing 10 hours of heavy traffic where you drive 200 feet, stop for 2 minute and drive another 200 feet. What is the difference in mileage? what is the difference in hours used? GDIs with Turbos are another animal entirely, these motors need oil that is spotless. Changing every 3-5K I don't think is too much after everything I have read. For somebody like you I think using a quality synthetic oil (and they all pretty much are) with a high quality filter (I think overlooked by many people) is just as important. If you want to know about which filters to buy, there are a few guys out there that cut open and inspect filters. Whip city is a favorite of mine but others are out there too. You'll learn more about oil filters than you ever cared to. But you'll learn which filters to buy and which to avoid.
As far as turbo GDI vs NA Port injection I agree but I would guess that the engine setup is taken into consideration when the manufacturer establishes a maintenance schedule in the first place. My owners manual, and I would guess it would be the same for other brands, dictates the conditions for 10K intervals. In order to qualify for 10K Toyota stipulates synthetic, oil, OE filter, and no severe duty driving (stop and go, short trips, excessive idling). If all of the requirements aren't met it clearly states in the manual to do 5K intervals. This is why I keep repeating in my videos for owners to read their manuals to see if their manufacturer even recommends 10k and what criteria must be met to do it.
@@EnthusiastsGarage Turbos put much higher stress on oils and GDI even higher. Honestly I doubt you will see any turbo and GDI engine last 300,000 miles like you would with the Toyota 1.8 or the Honda 2.0 motors. Also , be skeptical regarding OE consumables, though Toyota sources their filters from Denso which is a good filter. Some do not. A little research goes a long way. A Very dear friend of mine was Master Mechanic for Ford and he taught me plenty. Showed me a few cut up filters and it really opened my eyes.
@@rhelouin it gets so clogged up that the bypass filter activates all the time and the oil doesn’t get filtered anymore and in all fairness, it takes a lot for that to happen
Costco Kirkland, Walmart Syntech, Amazon Basics, all made by Warren Manufacturing, and very good oil. Paying more on other brands isn’t going to get you much more. Just use a good filter and change your oil by 5,000 miles.
We also can get Warren oils in other house brands like Meijer Oil and Rural King Oil. I run what’s on sale. Currently I’m using Valvoline Full Synthetic. My Menards had it in sale for $17.99 per 5 qts with 10% back so $16.19 per 5 qts. I picked up 24 5 qt jugs so we are set for 3/4 years. Grab the OE filters at my dealer 6 at a time for $5.49 each.
Thank you, this is the most informative oil lesson I have seen, with the numbers to back it up. I did not realize that synthetic oil can refer to a quality not the origin of the base oil.
I've been doing 10,000 mile changes for about 20 years, driving around 35,000 miles a year on my main work vehicle. Mix of highway and city. I currently have 310,000 miles on my 2014 3.6l Durango and it's running great. My previous 2006 Mazda was sold with 250k and still running great. I used Mobil1 full synthetic for a long time, then switched to Kirkland a few years ago when it came out. Let oil drain completely every time....and run wix/napa gold filters. Don't even check the oil between changes...probably should start doing that lol
It’s funny when you say I change the oil every 10,000 miles, people freak out they’re still doing 3000 and 5000 miles, lol😅 oil companies love them …….and if you actually read the filters or even on the bottles of oil, they say you can do that, I am with you every 10,000 miles I do the filter about 5000 miles out
Trucks hold a lot more oil. As a item that makes them heavy duty. Cars are not sized to have extra oil( quarts). Since they have bare minimum should change cars more often. Just what I am thinking.
@@johnjohnson9980 My Durango is a 3.6 liter and takes 6 quarts... Mazda just a 2.3 liter and takes 5 quarts. Typical car/suv. I do have a full size truck that takes 7 quarts... but it's also a 5.7 liter with two more cylinders so it makes sense to have a little more oil. But none of my vehicles are heavy duty or have a large oil reserve
@@wohoman2005 Not a bad plan, although I'd cut one open and actually see how much carbon is in there, if it looks clean you could probably stretch that safely too
I have been using Kirkland 5w30 for my 2010 Yaris for years, and recently, got a 2004 GMC Sierra 5.3 which also uses the same 3W30, so it makes sense for me to continue to buying the two bottle box as it makes it easy for me to make my regular oil changes, but also my vehicles are running great! I drive them fairly hard, moslty on the freeway, especially the Toyota, which is our daily driver. Toytota last change at 165k and truck at 202k So I average around 5000 miles with a good filter.
The issue I have with these tests are that the Mobil1 wasn’t the Extended Performance or High Mileage. I don’t even like Mobil1 because Amsoil Signature Series, Valvoline Extend Performance high mileage, and the Pennzoil Ultra Platinum are far better oils with top quality oil filters are superior and I have the blackstone labs results on five vehicles. And Most vehicles are severe service usage. I recommend 5000-7500 max.
Good testing and info. Thanks for bringing this to us. I think for these tests, a fuel additive should be used every 2000 miles. But use a lubricant type, and the same one, so the test will not have another variable. Use the recommended concentration. I agree that 10,000 miles on an oil change is ok for 90 % freeway driving, AND a fairly new engine (less than 100K miles). 5000 for mostly city driving.
Interesting. Looks as good as M1 here. I use Walmart Full Synthetic, which I believe is the same oil as the Costco and Amazon oils. All from Warren Industries and quality products. Recent oil change in my V-6 Silverado is noticeably different than the Pennzoil Platinum that was in it. Engine is quieter on acceleration, much quieter once at speed, and normal engine noises are more subdued at idle. I used a Fram Ultra filter and have been doing so, so the only difference is the oil. I do the changes myself. Very impressed. If I had a Costco near me, I'd run that without any concerns.
It is possible that the fuel additive freed up the top piston ring. The additive gets pushed into the top ring during the compression stroke. Better ring sealing keeps fuel from passing the rings.
Statements when it comes to oils around following the recommended manufacturer flat out makes me disagree with you on that.. they don’t ever recommend messing with your ATF either. I disagree. They tell you 10,000 mile oil changes. I disagree. On those two fronts I don’t agree with the manufacturers, plain and simple. I love the Kirkland oil. I wish they came out with OW 16. 😄
I do an oil change whenever one of my cars says it’s time. Usually about 10,000 miles. I use Kirkland synthetic. It’s cheap! Maybe the engines would last longer if I changed it more often? Who knows? I haven’t worn out an engine in decades. I typically keep my cars to 150-200k miles. At that point I don’t want the car anymore regardless of the fact that it still runs well. A little bit of maintenance makes most of today’s cars run a long time. Doubling up on the frequency wouldn’t get me a return.
Thanks for video and your experience. I think the point from this video and many other is today’s synthetic oil are all good enough and go the 10k interval. You have to find your comfort level be it 5k or 10k and then make sure you are consistent with changing it. Regular maintenance interval is the key. I personally do 5k interval based on my mixed driving and average 5k mileage per year. I have used Kirkland 0W-20 no issues. Mobile has YT video testing their mobile 1 on few cars driven over 100k with 10k interval. Engines were dismantled with minimal wear and clean.
Recently saw a Project Farm video comparing a number of synthetic oils. According to the UOA’s , SuperTech did slightly better than the Kirkland version. Essentially, they are identical. Just saying this because if you don’t have a Costco membership or don’t want one (like me), you can still get a quality synthetic oil at a great price. $18.99 for a 5 quart jug .
It's like comparing Bud Light and Coors Light - neither of them is great, but they both get the job done. Try High Performance Lubricants, and change your oil every 35K miles. Also, Boron is usually part of Borate-Esters and it's a multfunctional additive, and it acts mostly as a sacrificial anti-wear additive. The Kirkland and Mobil 1 additive packages are commonly refered to as "Dexos Additive Packages". They are so similar that they both probably came from the same additive supplier. Mobil makes some excelent motor oils in their upper tier product lines like ESP, FS, EP, and Delvac 1. Something like grey-bottle "Fuel Economy" 0W-20 is a vanilla run-of-the-mill product for Mobil, something they don't heavily invest in. If you want to upgrade your oil, get Mobil 1 ESP X2 0W-20 - available at Walmart now. Also, there is no such thing as an "Oil Store" - 😂- Also, Group III base oils are syntethics, and they provide better additive response than PAOs (IV) and Group V. Also... Group V has some real junk in the mix, so it just depends what you want from Group V, which usually is POE - to stabilize and improve solubility, pour point, and heat resistance, at the expense of accelerated oxidation.
I agree wholeheartedly that there is no “one size fits all” answer when it comes to oil change interval. I do a lot of short drives during the week (although in the weekends I do longer drives), and therefore I change the oil every 3000 miles. The reason I think I’m not overdoing it is that the color of oil is pretty dark after 3000 miles. Oil is relatively inexpensive but a modern engine is not…
Interesting but the maintenance light comes on at 5k miles which the manufacturer made it but 10k oil changes is never gonna happen on any of my cars. I personally use Havoline Pro-DS since 2018 which I change at 6 minths regardless of miles. Fuel system cleaner luke BG 44k platinum is key if used once a year. Great video information.
I use Kirkland 0w-20 in my 06 Ranger 2.3, 206,000 miles, Napa Gold filter, changed once a year at the end of summer, spends its life short hopping (commute is 1.3 miles each way) or in the hills on dirt roads, no added oil between changes. MIL 2013 Equinox 3.6, 81,000 miles, Kirkland 5w-30, Napa Gold filter, changed when the computer tells me to (between 5,000 and 8,000 miles) and zero issues. 157,000 on my 2013 Altima 2.5. Oil change every 15,000 miles, Ams Sig 0w-20 and Ams oil filter. 20% short hops, 80% 10 miles or more; zero oil added between changes. 19 Santa Fe 2.4, Ams Signature 0w-20 every 15,000; 10% short hops, 90% highway, zero oil added and 55,000 on the clock. Long intervals do not bother me on my long distance vehicles.
Before it was Costco, I bought PriceClub oil for my Toyota Supra did a change and went on a trip. After 500 miles, the oil pressure disappeared. I checked the level and it was fine, so I limped home at low speed. After another oil change (with real oil) everything was OK. More recently I have used Walmart and Amazon oils without problems, but it may be a while before I try Costco.
The 10,000 mile oil change interval was driven by European regulations which wanted to reduce the consumption of oil by extending oil change intervals. So for my VW’s I only use oils that meet VW specifications.
If I read the containers correctly they're both Dexos spec which is going to give you excellent performance. Supposedly the WalMart Supertech and Costco Kirkland are sourced from the same blender and since the Dexos spec versions of both are exhibiting such good results, they are raising the prices close to the name brands. However the Kirkland goes on sale every several months and seems like the best value to me. Thanks for publishing your study. That Corolla may run a half million miles...
Also Amazon basics oil as well. All 3 exact same oil. There tests to prove on the interwebs. I get whichever I can get cheapest. Only thing is I haven’t been able to get any high mileage Costco
I once asked a trusted source if I should use synthetic in my new daily driver. He said, "Don't bother. Just add one of these to each oil change." Then he plunked down a steel quart can of Bardahl oil supplement. I did that two or three times-didn't do analyses. No problems but I switched to M1 anyway because of convenience. I've also read that the manufacturer of store brand motor oils depends on where you live. In the South, it may very well be Warren. In the NE or MW or West, it may be Mobil or Chevron or any other company capable of refining motor oil.
Thank you for your time on doing all this test. Question for you. Does the bottle for your Kirkland oil say Dexos Gen 3? Or Gen 2? Thank you in advance!
Even though i am that guy who uses what the manufacturer recommends i cannot say costco stuff is bad, i have found that many kirkland products are just as good if not better than the competition, i wouldn’t be scared to use any of there products
Not planning to keep my car for more than 100k miles,but not planning to destroy my engine either. I use the Super Tech full syn and change my oil every 4-5k miles.
Don't forget all the start/stops with almost all new cars with the auto-off/on at the light feature. I hate it, thankfully I only have to just press the button to turn it off. So grateful I don't have to hold it down for 5-10 seconds.
I hate it too with the added drag on the starter plus all the extra electronics. It's a touchy feely thing that makes some people feel good about themselves.
Mobil 1 0w20 $50++/10gal. Kirkland $29.99/10gal (on sale right now). Kirkland just as good. Every oil change for my fleet is 23 quarts across 4 cars. Been running Kirkland in my Suburban from 30k to about now 83k. Doesn't burn a drop between 5k changes. Now startup noise. My Acura with 135k miles... Kirkland for about 80k miles. Excellent running engine not oil burning at all.
The subject of oil filters has been brought up in the comments. Did you use the same brand filter in all your testing and what filter do/did you use? (I know… opening another can of worms…)
My Prius burns oil but loves the Costco oil. Burns a lot less and the price can’t be beat. I change it myself every 3k miles with a OEM filter for around $20 and if it’s good enough for Project Farm it’s good enough for me
In my experience, just changing any oil on a regular basis (conventional oils 3000 or 3 months , synthetics 5000 or 6 months) usually result in long engine life…….for an average daily drivers … Performance engines are a different story…better oils typically is a better choice especially with turbos are in play.
from what I can tell its primarily crude, but it is important to note that oils have usually have more than base group in them. amsoil is usually primarily group 4 pao bases, pennzoil's higher end oils are GTL based which is still technically group 3 but its usually more uniform and pure.
Running 10k miles before changing the oil is a bit long in my opinion. In my opinion, full synthetic oil should be changed at about 5k/6 months. Don't forget to check the oil level every 2k miles (depending on whether the car is old or new), check it more often on older cars. I participate in a lifetime oil change package from Mazda on my CX-5. So I feel very secure about this, because I use the car very little, so every 6 months/2k miles I go to Mazda to change the oil. I don't know how long the motor will last??
I’ve always used Motorcraft (semi synthetic) on all my Ford trucks with good results, no oil consumption between changes at 5,000 miles or one year whichever comes first, Pennzoil on my other SUV’s, I’d say just go with a good quality oil, my cousin for example uses Castrol oils for his vehicles, my father favored Valvoline, we have a family history in construction work traveling hundreds of miles a week to different job locations, we’ve all had cars well over 200,000 - 300,000 miles a few at 450,000 plus miles.
@@marlu6373 Thanks, 5k has always worked well for my vehicles, I don’t use any of the Eco-oils like the 0W-16 or 20, I check oil regularly and top off if needed between oil changes, as far as full synthetic it may only give you an extra 1,000 miles of use compared to conventional or synthetic blend oils!
Would love to see an equivalent oil analysis of the same brands from the older Volvo turbocharged 5cyl engines. Those were known to be very harsh on oils
My understanding is that TBN is an older standard that is not dialed into oil condition as well as the metric called oxidation. Have you considered getting a used oil analysis for another lab that provides that such as Speediagnostix?
Yes, I have terrible experience with Mobil1 long-term full synthetic. And virgin analysis show that it's not very good compared to competitors like Pennzoil and Valvoline or basically any others to be honest because it always comes in last in virgin oil analysis.
@@ronswanson8563virgin oil analysis is just a baseline to judge you used oil analysis! TBN is still a good metric showing an oils resistance to become acidic
@@ronswanson8563 I check with 540Rat for his recommendations and pretty sure he scorched Mobil 1 extended oil and that it was worse than the regular Mobil 1. I personally stay away from extended use.
I use Mobil 1 and change every 10k with no issues. 7 quarts of water cooled engine oil lasts much longer. Doesn't use, never add. 212k and no oil leaks. I haven't been shown why I should switch yet. Sometimes we worry to much about unnecessary things
Why would you go so far over 5k? For oil changes, thats terrible... oils fairly cheap, esp the kirkland synthetic. 5k is like the standard for oil changes. 3k for old school, before synthetic
Hey great vid. So project farm also did these oil tests and Scotty Kilmer, the Kirkland brand and the Walmart super tech are bot made from the same oil manufacturer. Amsoil is and was the on,y oil that beat the supertech across the board. Check out there vids. Really intriguing
10K oil change....hm...sometimes you can get costco oil at $17 per 5q jug....filters are about $5-6 each if you find on sale. $23 DIY oil change !!! 5K is the ONLY way to go !!!
Very good video. My new Grand Cherokee has a clock for oil change. When I am at around 9K, the clock shows 10% life left. The dealer puts a sticker after an oil change to come back at 5K. Hello???? The service manual states to follow the instruments.
Only follow the manufacturers recommendations on OCIs if you only want to depend on reliability of the engine for the length of the warranty. That is how they set that 10,000 mile number. If you want to own it for 10 years and 200,000 miles change it every 5k.
Been using Costco's oil for my 2 vehicles for more than 5 years and absolutely love it.
Out of curiosity, what is there to love exactly and what filters are you using?
I know they have various mileage limits on oils as does Supertech. 5k, 10k and 20k
What kind of vehicle, how many miles and what are your oil change intervals?
@Balticblue93 I used to use penzoil high mileage comventional on my then 2007 honda civic. Used to have to add a quart every week. After switching to costcos i only added oil once a month. Sold civic with 265k miles.

Add a quart a week? there is a leak somewhere.
No better value out there. When on sale it can't be beat even by Amazon or Walmart supertech
Great video! You kept your oil analysis spreadsheet up throughout your detailed walk-through. Most other reviewers like more 'face time' and tend to rush through their presentations. I didn't have to pause the vid to absorb the info. Thank you, I'm headed to Cosco right now!
One thing to remember is that some oils, most often the ones with inferior base oil characteristics require more additives in order to meet the automotive specifications. It could be that the additive concentrations in the kirkland is higher due to this, but unless you run a FTIR analysis you can't really know for sure. Thanks for the informative video!
Very true sir. It’s very common with group 4 or 5 oils or the natural gas (GTL) base oils like pennzoil uses to use less additives as the base oil is better. Unfortunately the oil manufacturers don’t provide much information but I’m not aware of either oil using that base stock. There is a possibility Mobil 1 blends different base oils with group 3s to keep costs down.
@@EnthusiastsGaragelook at this. It'll clarify many questions about mobil 1 brand.

Yes !
Use ACEA
You can check the MSDS for all oils although they don't have list proprietary additives if they are not hazardous, as is my understanding. But the MSDS will say if the oil is PAO synthetic in most cases.
2007 Acura RL with 397,000 miles on it and I've always use OEM filter + Castrol Syntech oil on it. Finaly gave it to my son.
what was the viscosity of the oil you used and how often did you change?
Nice... too bad they don't make cars like they did back in the early 2000s. Folks need to change their oils every 3 to 5k, depending how you drive and the type of driving you do (in town or highway) Not 10k. That is usually about 2 engine oil changes a year. It's worth it. Espeically if you do it yourself ... get some car ramps (50 bucks)... and it is crazy easy, fast, and you can use the best oil and oil filter .... and you know it was done correctly.

Thank you sir I appreciate and have used oil analysis to set drain intervals and double-check that what I'm doing is still working. Also you are right on when you talk about the difference between group 3 synthetics and the true synthetic there is a difference 'full synthetic' does not equal 100% synthetic it is a marketing term

Excellent presentation. A few comments that you may take any way you like., I have been using Mobil 1 in my cars since 1976. I have not had a single oil related problem with any engine since that time. Before that I had a major brand nonsynthetic oil lose lubricity and destroy an engine in a Plymouth and another oil failure from sludge build up destroy an engine in a Ford. Then again I had an AMC six that ran over 300,000 miles with no problems on that same brand oil. When I sold it the engine was still solid. I used to change synthetic oil every 10,000 miles, but I have seen some engines so sensitive to things like film build up that I am now changing 5,000-mile intervals.
Sure. I've used mostly conventional and synthetic blends up until maybe a few years ago and have never had an oil related failure. There was , and is nothing remarkable about Mobil 1. If you get the warm fuzzies after installing it into your vehicles well then good for you. Just know that there is nothing superior about the so called holy Grail Mobil 1 . All you've been doing is paying more for advertising and a "reputation".
@@joeblowe7545 I agree that there is nothing about Mobil 1, that is better or worse than other synthetic oils. I was an AMC mechanic for years. I saw the insindes of many engines after only 100,000 miles on standard oils of the sixties and seventies. I have also torn down an AMC 258 six that had over 300,000 miles on it using Mobil 1. The difference was amazing. Cross hatching in the cylinders with no measurable wear. We miked the cams, lifters and rockers. Everything was still well in speck. There was no measurable wear on the bearings. I never saw an engine still in speck with much lower mileage running on conventional oils in the sixties and seventies. True conventional oils have improved a lot since then, but I will stick with synthetics from now on. BTW that engine had filter changes every 5,000 miles and full oil changes every 15,000 miles. Something I would never do in a modern engine. We ended up cleaning the engine really well and reassembling it, changing out only the piston rings, valves, gaskets and seals.. We also changed out the water pump for a newer type developed by AMC.
Was it a Pacer goldfish bowl? Best visibility of any hardtop in history!
Thanks for doing the test. Very informative. I've been using the Kirkland oil now for years with great results as all my vehicles generally go to 250K miles or more. However, I change my oil every 5000 miles, not the manufacturer recommended 10K. Oil is cheap--engines are expensive. Especially if you use the cheaper high quality oil from Kirkland. I assume you ran oil to 10K miles to make for easy rounded up number test. But I would never recommend that change interval. The savings from prolonged oil intervals are peanuts to engine wear damage, particularly on turbo engines where the turbos spool at up to 30K RPMs and need oil to keep them cooled, thus degrading the oil faster. Just changed my neighbors oil on 2017 Honda CR-V and it was black because of the turbo even though it had only 6K miles on it.
Excellent advice
Consider the fact that he had laboratory analysis done that showed active additive left and no consumption after 10k. I also change at ~5k but I have to admit there is no rational basis to recommend it to others.
So you don't trust the oil analysis?
Oil color does not tell you anything!
@@lenlaskowski7374Trust the test but the analysis was done on a 2015 Toyota Corolla which is one of the most bullet proof motors ever made in the World by Toyota. Change your oil every 5k & don't listen to this guy. If you don't believe me watch The Car Care Nut a 25year certified Master Toyota Mechanic and he screams at the top of his lungs that the 10k recommendation is BS. I trust the guy who has seen and fixed hundreds of blown Toyota & Lexus motors due to oil changes being done every 10k..
Great info…thanks. My former brother-in-law was a petroleum engineer. He was of the mind that the oil you used (assuming appropriate API rating and viscosity grade) was far less important than ensuring regular/shorter oil change intervals, especially for cars with inherent sludge problems created by poor design (e.g., Chrysler 2.7) or more complex engines, such as engines with cylinder deactivation systems. He used to say that full synthetic oils were clearly superior to conventional oils, but unnecessary for most people unless their car maker specifically recommended/required it (e.g., any turbo engine).
As he explained it, using synthetic oil was like putting six legs instead of four on the footstool in front of your favorite TV chair. You could do it and your stool would certainly be stronger...but it would just make your stool more expensive and it wasn’t going to make it last any longer.
I’ll never do 10k oil changes but thank you for this good info
Completely agree with this. Asking for trouble.
My 2006 BMW 3 series is now 190K. The system OCI is 19,000 miles, but I change 10,000-15,000 miles or 1 year.
So you know the new Volvo 860 semi trucks 2024 and actually the 2022s using 15\40 go 45,000 miles between oil changes
Agree. It's not just the base oil breaking down, it's the additives that keep the oil healthy. Just look at the oil when you drain it. If its black and burnt you waited too long.

I did 15K oil changes in my 2011 Kia Sedona for years using Mobil 1. Never had an issue, always passed smog, and the engine looked clean when I did the valve cover gaskets close to 200K miles on the van. Modern synthetics are great.
maybe you can get away with that type of interval on a big naturally aspirated 6 cylinder engine, but on a turbo charged engine a 15K mile interval would destroy the engine by 100K miles...especially a 4 cylinder turbo
@@cantwealljustgetalong2 Fair point. I would not stretch a turbo engine to 15K or even 10K oil changes.
That’s great, I’d have the oil analyse.

With kia you should change your oil every 3 to 5 thousand they tend to burn oil
my ex works for Chevron engine oil department, even she uses mobile1 and not their own company's top oil, she does analysis on her own car after each oil change as well
I had an uncle that worked for Mobil 1. They did a test where they ran an engine 100k miles .. 3k oil changes. They tore the engine down and it still had the wear marks on it... which means the engine had no wear on it. Crazy impressive. I use Mobil 1 European blend in my 2011 VW GTI. It has 103k on it. Drives great. No isses.
I have a 2010 Toyota Camry 2.5L four cylinder with a 6 Speed Manual. I drive about 400 miles a week back and forth to work all highway/interstate driving. Going between 70 to 80 mph everyday 5 days a week. I still change my oil at the 5,000 miles mark. I do about 3 to 5 oil changes a year. Thats between 15,000 to 20,000 miles a year. I've been using Castrol for many years and i recently switch to Kirkland 0W-20 due to price point and availability. Pretty good so far. Im currently on my 1st Kirkland bottle now in my Camry.

True synthetic oils would cost a few hundred dollars a gallon. This is one of the first videos I have seen that actually gets this correct concerning PAO's and other "synthetic" oils. Just my two cents as a Tribologist. Two thumbs up and WELL DONE!!!
I switched to Costco oil. Great quality like pretty much everything Costco has. Always changed oil every 5k miles religiously.
Facts
If you live in "The City" or an urban area, your type of driving qualifies as Severe Service; idling at traffic lights, stop and go, short trips, shutting the car off before it's been driven for 30 minutes. Keep that in mind when selecting your oil and determining change intervals.
yup he does state this at 15:10
How does this help us select oil? What you described is exactly my driving conditions, often just twice a day for kids school trip is 2 17 min sessions. My manual says 5W-30
@@NathanBrantley This goes for all types and brands of engine oil.
@@NathanBrantley
Use the same oil as the manufacturer recomends just change it more often
@@NathanBrantleybasically with the type of driving you do, you should be changing your oil every 3-5 thousand miles. Now if you were driving a 100 miles a day to work and back on the highway, you could do 10,000 according to this guy.
Great posting and kirkland & M1 similarities may explain why only those two burned more in my subaru outback. Once I switched to pennzoil or castrol, the burning was less. Also will be getting those Blackstone analysis for our older porsche boxster, especially for metal.
It's a Subaru thing.
Thanks for making this, great info!
I service multiple fleets and was at one point using Costco brand because of reviews. Things I noticed; the oil leaves behind a yellow tint residue on parts (head, covers, etc...) as it starts wearing, mobile one does not leave this residue. Also with Kirkland brand I noticed it causes gaskets to prematurely leak; seems like maybe the gaskets are hardening up faster than normal. Besides those two things it performed identical for the most part.
Another thing to consider is how long one leaves the oil to drip. We have 3 cars- 2021 Tacoma, 2021 Crosstrek, and a 2017 Jetta. The Crosstrek is done dripping in 10 minutes. The Tacoma is more like 30 minutes, and the Jetta takes 90+ minutes. Let all the drips get out of the crankcase, as you would be surprised how much oil volume a little drip can make! When I took my Taco to the dealership for a "Toyota Care" free oil change, they only had my truck back there for 13 minutes. That was the last time I let somebody else change my oil. I do my cars every 5k. Arguable I should probably change the jetta sooner than that since it is a turbo. I use Castro European oil in the Jetta, and Kirkland and Mobil one interchangeably in the Toyota and Subaru. (They are both 0W-20)
100% correct. I pull the drain plug and then walk away for an hour or two and find something else to do.
Yes for sure on the Turbos... change it every 3k. A Turbo is expensive. Oil is not expensive in comparison.
A lot of fuss over nothing. Let it drip for 10 minutes or so. Your cars will never know the difference. My brother once told me he let his oil drain over night!. Some OCD and maybe some insanity going on there.
@@joeblowe7545 Agree. I have an independent Honda garage do mine. They let it drip for about five minutes and cork her up. I have 270K on my 2005 Honda Pilot with 5K conventional oil changes. Probably going to get a 2020 Passport EXL with 17K on it.
Excellent. I have a 2006 Matrix (Corolla) 4WD with 223,000 miles and it runs perfect. Been using Kirkland 5w-30 for the last 100k miles and M1 (at $25/jug) before that with 5k OCI and OEM filter I recently bought 4 jugs for 68 bucks online. Vehicle used for ride share/delivery. I think I've saved over $4000 doing my own oil changes
Great video, great information, I change once a year, and from now on it's gonna be Kirkland. Thank you
You are correct on many things but some things I think need clarification. If you have a naturally aspirated engine and drive all highway miles, going 10K miles between oil changes shouldn't be unreasonable providing certain things are met. First Synthetic oil. Second (and possibly more importantly) using a high quality oil filter that can go at least 10K miles. If your oil filter gets used up at 5k miles, you will have another 5k miles where the filter does nothing. So the filter is important. All oils that follow their designated specification should be OK and then it is a matter of brand preference. A Dexos 1 oil is a Dexos 1 oil. However if you drive lots of city/stop and go driving and/or have a turbo engine with GDI, I think going over 5K miles is pushing it. With City v high driving, it isn't so much the mileage as it is the hours. You do 10 hours of high miles at 75 miles and hour v doing 10 hours of heavy traffic where you drive 200 feet, stop for 2 minute and drive another 200 feet. What is the difference in mileage? what is the difference in hours used? GDIs with Turbos are another animal entirely, these motors need oil that is spotless. Changing every 3-5K I don't think is too much after everything I have read.
For somebody like you I think using a quality synthetic oil (and they all pretty much are) with a high quality filter (I think overlooked by many people) is just as important.
If you want to know about which filters to buy, there are a few guys out there that cut open and inspect filters. Whip city is a favorite of mine but others are out there too. You'll learn more about oil filters than you ever cared to. But you'll learn which filters to buy and which to avoid.
As far as turbo GDI vs NA Port injection I agree but I would guess that the engine setup is taken into consideration when the manufacturer establishes a maintenance schedule in the first place. My owners manual, and I would guess it would be the same for other brands, dictates the conditions for 10K intervals. In order to qualify for 10K Toyota stipulates synthetic, oil, OE filter, and no severe duty driving (stop and go, short trips, excessive idling). If all of the requirements aren't met it clearly states in the manual to do 5K intervals. This is why I keep repeating in my videos for owners to read their manuals to see if their manufacturer even recommends 10k and what criteria must be met to do it.
@@EnthusiastsGarage Turbos put much higher stress on oils and GDI even higher. Honestly I doubt you will see any turbo and GDI engine last 300,000 miles like you would with the Toyota 1.8 or the Honda 2.0 motors. Also , be skeptical regarding OE consumables, though Toyota sources their filters from Denso which is a good filter. Some do not. A little research goes a long way. A Very dear friend of mine was Master Mechanic for Ford and he taught me plenty. Showed me a few cut up filters and it really opened my eyes.
How does an oil filter get used up?
@@rhelouin it gets so clogged up that the bypass filter activates all the time and the oil doesn’t get filtered anymore and in all fairness, it takes a lot for that to happen
@@jamescaron6465if the filter is really high quality wouldn't it clog more/faster than a low quality filter which is not filtering as well?
With high-mileage engines, I am most worried about fuel contamination / particulate contamination. Going to start buying Costco oil!!!
Costco Kirkland, Walmart Syntech, Amazon Basics, all made by Warren Manufacturing, and very good oil. Paying more on other brands isn’t going to get you much more. Just use a good filter and change your oil by 5,000 miles.
Correct only oil that’s is a little better than Mobil 1 is shell roto full synthetic very hard to find.
We also can get Warren oils in other house brands like Meijer Oil and Rural King Oil.

Thank you, this is the most informative oil lesson I have seen, with the numbers to back it up. I did not realize that synthetic oil can refer to a quality not the origin of the base oil.
I've been doing 10,000 mile changes for about 20 years, driving around 35,000 miles a year on my main work vehicle. Mix of highway and city. I currently have 310,000 miles on my 2014 3.6l Durango and it's running great. My previous 2006 Mazda was sold with 250k and still running great. I used Mobil1 full synthetic for a long time, then switched to Kirkland a few years ago when it came out. Let oil drain completely every time....and run wix/napa gold filters. Don't even check the oil between changes...probably should start doing that lol
It’s funny when you say I change the oil every 10,000 miles, people freak out they’re still doing 3000 and 5000 miles, lol😅 oil companies love them …….and if you actually read the filters or even on the bottles of oil, they say you can do that, I am with you every 10,000 miles I do the filter about 5000 miles out
Trucks hold a lot more oil. As a item that makes them heavy duty. Cars are not sized to have extra oil( quarts). Since they have bare minimum should change cars more often. Just what I am thinking.
@@johnjohnson9980 My Durango is a 3.6 liter and takes 6 quarts... Mazda just a 2.3 liter and takes 5 quarts. Typical car/suv. I do have a full size truck that takes 7 quarts... but it's also a 5.7 liter with two more cylinders so it makes sense to have a little more oil.

I have been using Kirkland 5w30 for my 2010 Yaris for years, and recently, got a 2004 GMC Sierra 5.3 which also uses the same 3W30, so it makes sense for me to continue to buying the two bottle box as it makes it easy for me to make my regular oil changes, but also my vehicles are running great! I drive them fairly hard, moslty on the freeway, especially the Toyota, which is our daily driver. Toytota last change at 165k and truck at 202k So I average around 5000 miles with a good filter.
What does that two bottle pack run you? I've been using Supertech which I believe is the same oil. It's about $19 for a 5 quart.
been using Costco oil for 10 years now...300k miles on an 06 Sequoia and still on original engine/trans.
The issue I have with these tests are that the Mobil1 wasn’t the Extended Performance or High Mileage. I don’t even like Mobil1 because Amsoil Signature Series, Valvoline Extend Performance high mileage, and the Pennzoil Ultra Platinum are far better oils with top quality oil filters are superior and I have the blackstone labs results on five vehicles. And Most vehicles are severe service usage. I recommend 5000-7500 max.
High Mileage just has chemicals to soften old seals.
also lower detergency to let the sludge not go into suspension@@mitchhedberg4415
Great content! Hope you will do this on a regular basis to check if oil formulation will change. Now thinking to switch to Kirkland synthetic oil.
Great job easy to understand
Good testing and info. Thanks for bringing this to us.
I think for these tests, a fuel additive should be used every 2000 miles. But use a lubricant type, and the same one, so the test will not have another variable. Use the recommended concentration.
I agree that 10,000 miles on an oil change is ok for 90 % freeway driving, AND a fairly new engine (less than 100K miles). 5000 for mostly city driving.
Interesting. Looks as good as M1 here. I use Walmart Full Synthetic, which I believe is the same oil as the Costco and Amazon oils. All from Warren Industries and quality products. Recent oil change in my V-6 Silverado is noticeably different than the Pennzoil Platinum that was in it. Engine is quieter on acceleration, much quieter once at speed, and normal engine noises are more subdued at idle. I used a Fram Ultra filter and have been doing so, so the only difference is the oil. I do the changes myself. Very impressed. If I had a Costco near me, I'd run that without any concerns.
Dusty conditions and temperatures above 90 degrees F calls for a more frequent change.
My engine air intake filter is always sparkly white.
It is possible that the fuel additive freed up the top piston ring. The additive gets pushed into the top ring during the compression stroke. Better ring sealing keeps fuel from passing the rings.
Statements when it comes to oils around following the recommended manufacturer flat out makes me disagree with you on that.. they don’t ever recommend messing with your ATF either. I disagree. They tell you 10,000 mile oil changes. I disagree. On those two fronts I don’t agree with the manufacturers, plain and simple. I love the Kirkland oil. I wish they came out with OW 16. 😄
I do an oil change whenever one of my cars says it’s time. Usually about 10,000 miles. I use Kirkland synthetic. It’s cheap!
Maybe the engines would last longer if I changed it more often? Who knows? I haven’t worn out an engine in decades.
I typically keep my cars to 150-200k miles. At that point I don’t want the car anymore regardless of the fact that it still runs well. A little bit of maintenance makes most of today’s cars run a long time. Doubling up on the frequency wouldn’t get me a return.
Thanks for video and your experience. I think the point from this video and many other is today’s synthetic oil are all good enough and go the 10k interval. You have to find your comfort level be it 5k or 10k and then make sure you are consistent with changing it. Regular maintenance interval is the key. I personally do 5k interval based on my mixed driving and average 5k mileage per year. I have used Kirkland 0W-20 no issues. Mobile has YT video testing their mobile 1 on few cars driven over 100k with 10k interval. Engines were dismantled with minimal wear and clean.
Recently saw a Project Farm video comparing a number of synthetic oils.
According to the UOA’s , SuperTech did slightly better than the Kirkland version.
Essentially, they are identical.
Just saying this because if you don’t have a Costco membership or don’t want one (like me), you can still get a quality synthetic oil at a great price.
$18.99 for a 5 quart jug .
Supertech and Kirkland are both made by Warren.
It's like comparing Bud Light and Coors Light - neither of them is great, but they both get the job done. Try High Performance Lubricants, and change your oil every 35K miles. Also, Boron is usually part of Borate-Esters and it's a multfunctional additive, and it acts mostly as a sacrificial anti-wear additive. The Kirkland and Mobil 1 additive packages are commonly refered to as "Dexos Additive Packages". They are so similar that they both probably came from the same additive supplier. Mobil makes some excelent motor oils in their upper tier product lines like ESP, FS, EP, and Delvac 1. Something like grey-bottle "Fuel Economy" 0W-20 is a vanilla run-of-the-mill product for Mobil, something they don't heavily invest in. If you want to upgrade your oil, get Mobil 1 ESP X2 0W-20 - available at Walmart now. Also, there is no such thing as an "Oil Store" - 😂- Also, Group III base oils are syntethics, and they provide better additive response than PAOs (IV) and Group V. Also... Group V has some real junk in the mix, so it just depends what you want from Group V, which usually is POE - to stabilize and improve solubility, pour point, and heat resistance, at the expense of accelerated oxidation.
I have used Supertech from Walmart in all of my autos which I maintain and all vehicles have run in excess of 250K with no oil related failures.
I agree wholeheartedly that there is no “one size fits all” answer when it comes to oil change interval. I do a lot of short drives during the week (although in the weekends I do longer drives), and therefore I change the oil every 3000 miles. The reason I think I’m not overdoing it is that the color of oil is pretty dark after 3000 miles. Oil is relatively inexpensive but a modern engine is not…
Interesting but the maintenance light comes on at 5k miles which the manufacturer made it but 10k oil changes is never gonna happen on any of my cars. I personally use Havoline Pro-DS since 2018 which I change at 6 minths regardless of miles. Fuel system cleaner luke BG 44k platinum is key if used once a year. Great video information.
Good score for Costco but a better +++ rating for Blackstone, their tests are the best for the $$$. Bob in Nevada
I use Kirkland 0w-20 in my 06 Ranger 2.3, 206,000 miles, Napa Gold filter, changed once a year at the end of summer, spends its life short hopping (commute is 1.3 miles each way) or in the hills on dirt roads, no added oil between changes. MIL 2013 Equinox 3.6, 81,000 miles, Kirkland 5w-30, Napa Gold filter, changed when the computer tells me to (between 5,000 and 8,000 miles) and zero issues.
157,000 on my 2013 Altima 2.5. Oil change every 15,000 miles, Ams Sig 0w-20 and Ams oil filter. 20% short hops, 80% 10 miles or more; zero oil added between changes. 19 Santa Fe 2.4, Ams Signature 0w-20 every 15,000; 10% short hops, 90% highway, zero oil added and 55,000 on the clock. Long intervals do not bother me on my long distance vehicles.
The Napa Gold's are junk now.
Before it was Costco, I bought PriceClub oil for my Toyota Supra did a change and went on a trip. After 500 miles, the oil pressure disappeared. I checked the level and it was fine, so I limped home at low speed. After another oil change (with real oil) everything was OK. More recently I have used Walmart and Amazon oils without problems, but it may be a while before I try Costco.
They are exactly the same oil. The same company makes them for all 3 of them
The 10,000 mile oil change interval was driven by European regulations which wanted to reduce the consumption of oil by extending oil change intervals. So for my VW’s I only use oils that meet VW specifications.
I would imagine then , that SuperTech would be right up there with the Kirkland since it’s also made by Warren Distribution.
could be some small variances in the additives package but they should be pretty close.
Excellent vid, very informative 👍🏽
We suggest a fuel system cleaner once a year.
Usually, we suggest the fall to ensure cold weather start reliability.
If I read the containers correctly they're both Dexos spec which is going to give you excellent performance. Supposedly the WalMart Supertech and Costco Kirkland are sourced from the same blender and since the Dexos spec versions of both are exhibiting such good results, they are raising the prices close to the name brands. However the Kirkland goes on sale every several months and seems like the best value to me.
Thanks for publishing your study. That Corolla may run a half million miles...
Also Amazon basics oil as well. All 3 exact same oil. There tests to prove on the interwebs. I get whichever I can get cheapest. Only thing is I haven’t been able to get any high mileage Costco
@@ajmedeiros77If your motor does not leak you do not need high mileage oil.
I once asked a trusted source if I should use synthetic in my new daily driver. He said, "Don't bother. Just add one of these to each oil change." Then he plunked down a steel quart can of Bardahl oil supplement. I did that two or three times-didn't do analyses. No problems but I switched to M1 anyway because of convenience. I've also read that the manufacturer of store brand motor oils depends on where you live. In the South, it may very well be Warren. In the NE or MW or West, it may be Mobil or Chevron or any other company capable of refining motor oil.
great informative video, did a good job of explaining the data.
Thank you for your time on doing all this test. Question for you. Does the bottle for your Kirkland oil say Dexos Gen 3? Or Gen 2? Thank you in advance!
You should check out penzoil platinum vs ultra platinum. These are cheap but extremely high quality oils
Even though i am that guy who uses what the manufacturer recommends i cannot say costco stuff is bad, i have found that many kirkland products are just as good if not better than the competition, i wouldn’t be scared to use any of there products
Not planning to keep my car for more than 100k miles,but not planning to destroy my engine either. I use the Super Tech full syn and change my oil every 4-5k miles.
Likewise
Don't forget all the start/stops with almost all new cars with the auto-off/on at the light feature. I hate it, thankfully I only have to just press the button to turn it off. So grateful I don't have to hold it down for 5-10 seconds.
im honestly surprised more people aren't talking about that. my truck has that so I put an auto start eliminator on it.
I hate it too with the added drag on the starter plus all the extra electronics. It's a touchy feely thing that makes some people feel good about themselves.
Mobil 1 0w20 $50++/10gal. Kirkland $29.99/10gal (on sale right now). Kirkland just as good. Every oil change for my fleet is 23 quarts across 4 cars. Been running Kirkland in my Suburban from 30k to about now 83k. Doesn't burn a drop between 5k changes. Now startup noise. My Acura with 135k miles... Kirkland for about 80k miles. Excellent running engine not oil burning at all.
Thank you. Thank you. Very informative.
The subject of oil filters has been brought up in the comments. Did you use the same brand filter in all your testing and what filter do/did you use? (I know… opening another can of worms…)
Stock Toyota filter in all these tests
My Prius burns oil but loves the Costco oil. Burns a lot less and the price can’t be beat. I change it myself every 3k miles with a OEM filter for around $20 and if it’s good enough for Project Farm it’s good enough for me
Kirkland=Super Tech Full Syn/10k=Amazon Basics Full syn. For all intents and purposes same oils made by Highline Warren, formerly Warren Dist.
All oils have an API, American Petroleum Institute, rating. Please include the ratings of these oils in your analysis.
Oils are like the old VCRs , 3 companies make it but 100 make labels .
In my experience, just changing any oil on a regular basis (conventional oils 3000 or 3 months , synthetics 5000 or 6 months) usually result in long engine life…….for an average daily drivers …
Performance engines are a different story…better oils typically is a better choice especially with turbos are in play.
is the Kirkland base stock composed of petroleum base or natural gas base ? (Amsoil and Pennzoil Ultra Max are Natural gas base stock)
from what I can tell its primarily crude, but it is important to note that oils have usually have more than base group in them. amsoil is usually primarily group 4 pao bases, pennzoil's higher end oils are GTL based which is still technically group 3 but its usually more uniform and pure.
Running 10k miles before changing the oil is a bit long in my opinion. In my opinion, full synthetic oil should be changed at about 5k/6 months. Don't forget to check the oil level every 2k miles (depending on whether the car is old or new), check it more often on older cars. I participate in a lifetime oil change package from Mazda on my CX-5. So I feel very secure about this, because I use the car very little, so every 6 months/2k miles I go to Mazda to change the oil. I don't know how long the motor will last??
Will they just do the "free" oil change or do you have to get and pay for other stuff.
I run synthetic in everything and ethanol free gas in my small engines..mower, blower, generator etc
I’ve always used Motorcraft (semi synthetic) on all my Ford trucks with good results, no oil consumption between changes at 5,000 miles or one year whichever comes first,
Pennzoil on my other SUV’s, I’d say just go with a good quality oil, my cousin for example uses Castrol oils for his vehicles, my father favored Valvoline, we have a family history in construction work traveling hundreds of miles a week to different job locations, we’ve all had cars well over 200,000 - 300,000 miles a few at 450,000 plus miles.
Don"t go 5 K on synthec blend go 3 k
@@marlu6373 Thanks, 5k has always worked well for my vehicles, I don’t use any of the Eco-oils like the 0W-16 or 20, I check oil regularly and top off if needed between oil changes, as far as full synthetic it may only give you an extra 1,000 miles of use compared to conventional or synthetic blend oils!
Now to remove the valve cover to see . And maybe a boroscope ? to see what orfices look like , spark plug holes , etc .
Very informative. Thank you.
I’ve always been a mobile one guy but just picked up 2, 5 quart jugs at Costco for 38.99
Would love to see an equivalent oil analysis of the same brands from the older Volvo turbocharged 5cyl engines. Those were known to be very harsh on oils
My understanding is that TBN is an older standard that is not dialed into oil condition as well as the metric called oxidation. Have you considered getting a used oil analysis for another lab that provides that such as Speediagnostix?
Yes, I have terrible experience with Mobil1 long-term full synthetic. And virgin analysis show that it's not very good compared to competitors like Pennzoil and Valvoline or basically any others to be honest because it always comes in last in virgin oil analysis.
@@ronswanson8563virgin oil analysis is just a baseline to judge you used oil analysis! TBN is still a good metric showing an oils resistance to become acidic
@@ronswanson8563 I check with 540Rat for his recommendations and pretty sure he scorched Mobil 1 extended oil and that it was worse than the regular Mobil 1. I personally stay away from extended use.
I use Mobil 1 and change every 10k with no issues. 7 quarts of water cooled engine oil lasts much longer. Doesn't use, never add. 212k and no oil leaks. I haven't been shown why I should switch yet. Sometimes we worry to much about unnecessary things
Like you said, "do an oil analysis if you plan on keeping a car",
.......but also change your oil every 5k if you plan on keeping it also, not 10k.
Warranty will ask for your maintenance records. 10K is not recommended by most manufacturers.
Of course manufacturer doesn't want the vehicle to last past warranty so you will buy a new one
Why would you go so far over 5k? For oil changes, thats terrible... oils fairly cheap, esp the kirkland synthetic. 5k is like the standard for oil changes. 3k for old school, before synthetic
The head engineer for the GTR said you can use the cheapest oil but change every 3k. I’ll take his advice.
i use costco oil and change it myself every 3000 miles. That's a bit extreme but I'm happy with it.
i do 3K mile oil changes too. oil and filters are cheap i cant justify going even 5K between changes
Hey great vid. So project farm also did these oil tests and Scotty Kilmer, the Kirkland brand and the Walmart super tech are bot made from the same oil manufacturer. Amsoil is and was the on,y oil that beat the supertech across the board. Check out there vids. Really intriguing
Walmart is blended by Warren oil company.
And pennzoil platinum made from natural gas.
Amsoil is a whole class above anything Warren puts out.
My next choice is Pennzoil Ultra Platinum. Everything else is below them.
Thanks for telling the truth about false ads about “Full Synthetic”. But Group 4 Amsoil is $11-13/qt (I use it)
10K oil change....hm...sometimes you can get costco oil at $17 per 5q jug....filters are about $5-6 each if you find on sale. $23 DIY oil change !!! 5K is the ONLY way to go !!!
The lab says you're wrong.
Interesting. The Calcium and Magnesium content is excellent - Best start adding engine oil to my cornflakes?
This is absolutely great video. Where do you get that test from?
Sir:
What group of synthetic oil is the Kirkland oil belong to ? and who is the OEM for the Kirkland oil.
Thanks.
I believe that he said the Kirkland was in group 3 along with most other full synthetic oils in that price range
Very good video. My new Grand Cherokee has a clock for oil change. When I am at around 9K, the clock shows 10% life left. The dealer puts a sticker after an oil change to come back at 5K. Hello???? The service manual states to follow the instruments.
Only follow the manufacturers recommendations on OCIs if you only want to depend on reliability of the engine for the length of the warranty. That is how they set that 10,000 mile number. If you want to own it for 10 years and 200,000 miles change it every 5k.
