![Best Synthetic Oils 2024 [Don't Buy Until You WATCH This!]](/img/n.gif)
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.
@@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.
@@violinforever
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
My Honda I used Castrol I change 3k miles no matter what oil it has 355k miles on it now still runs good
It also depends on the oil type.
smart
I change the oil in my Toyota every 20,000 to 23,000 miles with mobil -1 and it now has 276,000 miles on it, is nice & clean inside of it, doesn't use a drop of oil in the 20kmile interval. I've also sent my oil to the lab as this guy has done and my report values are the same as his and in some cases better even though my change interval is twice as his. 3k miles is only warranted if you short city driving, especially in cold weather (severe service)
And you are changing WAY too frequently
@@WaterDR-tw8rethere's no such thing.
Thanks for this test! Good to know Kirkland oil is good.
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.
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.
This guy is quite smart and his content is organized, interesting, and relevant. Great stuff!
Thanks for making this, great info!
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.
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 vid, very informative 👍🏽
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.
ua-cam.com/video/NJanSk3hBus/v-deo.htmlsi=2z1V25YDGAmx_Tt0
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.
Thanks for the video! I’m a 5k mi OCI guy with all of our DD cars.
Great video, great information, I change once a year, and from now on it's gonna be Kirkland. Thank you
Great commuter you have there. I rock a ‘12 civic coupe manual transmission and plan to run it for another 20 years.
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.
awesome info! i was alway curious about the lab analysis on kirkland oils
Thank you for sensible advice on oil change intervals
Nice garage, very organized.
great informative video, did a good job of explaining the data.
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.
@@Rojaktube change every 5k man, dont do that to your poor engine
😮The last couple minutes talking about oill change interval is the best I've seen😃
Great job easy to understand
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!
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.
@@erike7297it’s on sale in warehouse right now. 2 jugs of 5 qt each jug. 30.99.
@@erike7297 it goes on sale about twice a year
@erike7297 Kirkland oil is on sale right now. I just nought 10 quarts on Sunday. Their sales should be nationwide.
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.
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.
Very informative. Thank you.
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..
Nice job
I first used synthetic oil in 1977. I purchased Amsoil back then and yes it was EXPENSIVE!
Big Daddy Don Garlits, Kendall Motorola got me hooked, but then they quit selling it around here
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....
Do it. Value is key
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
Well done
Always been using Kirkland/Walmart oils for years at 4k miles with no issues but switched to ST advanced synthetic.
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.
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.
Dusty conditions and temperatures above 90 degrees F calls for a more frequent change.
My engine air intake filter is always sparkly white.
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.
Kirkland is exactly the same as super tech and Amazon oils. Can’t beat it for the price. I use valvoline synthetic high mileage or Penzoil ultra. Great informative video Thanks
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 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.
What brand and model of oil filter you use for your application?
@@armando9293 I use either the TRD Oil filter or the OEM Oil Filter, which I both buy from my local Toyota Dealership.
You can't beat a Toyota engine. Change oil and they'll run forever
@@armando9293 Always OEM nothing else.
Great video thanks. I use Kirkland oil as well. What type of fuel system cleaner did you use? Thxs again.
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?
Should I wait for my dashboard check engine light on an oil change monitor notification before my oil change?
Should I still change my 2011 Lexus RX 450h's oil, even if my SAE 0W-20 synthetic oil is a clear amber color (not dark), after 3 years of driving 1000 miles only?
You should check out penzoil platinum vs ultra platinum. These are cheap but extremely high quality oils
Racing green. Beautiful color.
BRG, even better.
What about the “Base” oil pennzoil PUP oil uses since it’s made from Natural Gas? Is that the “Best”? What base oil does Amsoil use?
I change the oil (PUP) in my ‘19 Power Wagon by the hour meter, not the mileage.
My first oil change on my performance motorcycle in the mid 90's resulted in a 200 rpm idle speed increase with Mobil 1. That sold me. My current Silverado and Tahoe each have 200,000 miles with no mechanical problems and no sludge. What was the difference in mileage(or did I miss it)?
It’s different on motorcycles because the engine oil is also the clutch fluid. Mobil 1 in motorcycles is golden.
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 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.
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!
That lovely JVC on top of your shelf.... still works?
I switched to Costco oil. Great quality like pretty much everything Costco has. Always changed oil every 5k miles religiously.
Do they have a high mileage blend?
Looking at this, I'm taking the M1 every day. Looking at the add pack, seems like whoever is formulating the Kirkland isn't using as high a grade of base oil as M1 and having to add more additives to get up to the same standard. Don't like the high calcium in the Kirkland either. That's fighting the zinc and phosphorus. Just remember, more additive does not equal better.
Exactly right.
Well I’d say that fine but I’d bet anything both our engines will make it to 300k it’s just that Kirkland will save you a bunch of cash over that timeframe
Since I have a high performance engine, 3.5 Ecoboost in my 2019 Raptor, I change my oil every 5,000 miles or annually whichever comes first with Costco 5W-30 and the Motorcraft FL-500S filter.
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
Until I see a picture of a cam sensor or the underneath of a valve cover I ain't believe in none of it
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.
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)
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.
Nice video.
Where do the averages come from, that is my issue. Are the averages specific to this specific engine with this level of mileage ? I highly doubt it.
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
Ive been using pup on my ram 5.7. Shpuld I give kirkland a try? Why mess with a good thing.
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
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.
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.
Was going to guess Northern NuJoisey or Southern upstate NuYawk. NJ it is!
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.
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.
My car recommends the 0-40 dexosR type oil. Only the dealer had it & it was expensive. I don’t take my car to the track, so do you think I must go with type R, or the regular Mobil 1?
depends if it meets the manufacturers specs.
Nice double cassette deck boombox.
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
Could you do a comparison between Amazon basic oil vs. Kirkland oil?
they are basically the same.
Love the SVT flag. Had two Contour SVT’s back in the day. Wish Ford made some comparable today.
With high-mileage engines, I am most worried about fuel contamination / particulate contamination. Going to start buying Costco oil!!!
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.
I've switch from Mobil 1 to Costco oil and save 50% percent over Mobil 1. i don't feel any different driving with costco or mobil 1 oil?
Compare the ingredients of each product new vs used.Many have very different ingredients too begin with,not equal amounts of the same ingredients for each oil brand,some have more of each or less,so the numbers are somewhat moot unless you compare the exact starting ingredients,then see what remains after each brand used.But good job on the presentation.
What filter was used? Did you use the same type each time? some filters can filter better than others because they have higher efficiency. This will make a difference in some of the impurities you see in the oil.
all tests with the OE toyota filter
We suggest a fuel system cleaner once a year.
Usually, we suggest the fall to ensure cold weather start reliability.
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
Good video.
What determins a quality oil is the VI (Viscosityb Index 11:25) of the oil. The higher the number the better the oil.
The viscosity index doesn’t have anything to do with the bare stock. Viscosity index is your oil weight, which can shear down, get diluted with fuel, or thicken overtime due to oxidation. Which is why they test it in the oil analysis at both a cold and operating temp. The base stock is what you’re referring to. And yes higher is better to an extent. Although a group IV is a true full synthetic and would be the best. Group V is for oils whos base does not fit into any of the I-IV categories, so it’s not necessarily better than a group IV.
@@jfitz9624 From what I understand the VI is the oils ability to stay in grade at vareing tempatures.
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.
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 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…
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.
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.
@@chrisanderson4799 You’re from the Upper Midwest then. I wish we had Menards in my area.
Totally agree! Amazon oil is very good! A lot of the oil is made by the same companies
Couldn’t have said it better!
Should I look for synthetic oil in my 40 year old Mercedes, or the old 20/50 mineral oil as it was designed for?
I would see what API service standard is recommended. some older cars use older standards.
Old school seals don't like synthetic.
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
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.
I drive a 2002 ford 7.3 diesel whatever oil do you recommend. Oil change every 5,000
Rotella T6
And 5k OCI is probably too soon for a diesel running full synthetic
Wonder how it would hold up in a turbo direct injection motor
Bad

I’ve always been a mobile one guy but just picked up 2, 5 quart jugs at Costco for 38.99
Both use basestock and purchase an additive package from lubrizol or afton... so it doesn't matter...
Now to remove the valve cover to see . And maybe a boroscope ? to see what orfices look like , spark plug holes , etc .
been using Costco oil for 10 years now...300k miles on an 06 Sequoia and still on original engine/trans.
My Prius burns oil but loves the Costco oil. Burns a lot less and the price can’t be beat. I change it myself with a OEM filter for around $16 and if it’s good enough for Project Farm it’s good enough for me
Which company do you use to have a engine oil analysis done
Good score for Costco but a better +++ rating for Blackstone, their tests are the best for the $$$. Bob in Nevada
Post link where to get the oil analysis test.
Blackstone labs
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.
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
