0W-8 Motor Oil: Too THIN to Trust? Let's Find Out!

- Опубликовано: 13 июн 2024
- How thin is 0W-8 motor oil? Toyota now calls for 0W-8 motor oil, which was only recently approved for use by the API. Can it actually protect the engine? Do Toyota dealerships actually install 0W-8 when they do the "free" oil changes? In this video, we put used oil analysis to work to get the answers to those questions, and the results are quite shocking!
Speaking of thin oils, we also took a sample of the CVT fluid from the transmission as well, so check out those results at the end of the video.
In a previous video, I changed the oil in my daughter's new Toyota Corolla before it had 1,000 miles on it. Here's the link to that video: • AVOID the ONE MISTAKE ...
Then we changed it again after about 3,000 miles. Here's the link to that video: • NEW Engine BREAK-IN: T...
At both oil changes, the Toyota recommended 0W-8 was not yet available because the American Petroleum Institute (API) had not yet approved the use of 0W-8 oils in the US.
Now that it is time for the first "free" oil change at the dealership, are they going to use the Toyota 0W-8 oil? By taking a sample of the oil from the engine AFTER the oil change with a vacuum extraction pump we find out!
Since we are talking about oil changes, here are some links to previous videos on oil filters and oil change procedures:

Here's the link to the research report from Oak Ridge National Lab on the special 0W-12 oil. www.osti.gov/biblio/1798600
Who has written that and nobody read it...?😂
In abstract:
"up to 9.9% better fuel economy for the IL-containing SAE 0W-12 experimental oil compared with selected commercial SAE 5W-30 and 0W-20 engine oils."
The 0w-20 had no info in the paper and the table just say "n/a".
So there is NO measured benifits in this paper anyway that there is ANY fule economy savings to be had going from 0w-20 to 0W-12 with or without whatever additives (IL) in it.
A misleading abstract and a assumption that is unverified by the report. (it probably has likely one but they can not claim something they have not tested!)🤔 💖
Did this pass for turbo charged? :)
Speaking of transmission fluid, the myth of ATF having miraculous cleaning abilities would be a great topic for a video. I personally think ATF doesn't have special cleaning abilities, and people just think it does because they don't understand transmissions don't collect carbon like engine oil does. But getting the facts from you could finally end or confirm this myth.
@@AmazonasBiotopagreed. My car calls for 0-W16 and I never saw more than 38.5 mpg around town. Funny thing is the oil change place didn’t have 0-W16 so I just told them use Mobile1 5-W20. Since the oil change I’m getting 40.5 mpg around town. 🤔
@jalofanclub
Yes, yesterday I did a oil change on my 2010 Prius gen 3.
Been using 0w-20 and decided to put 0w-16 in it for the first time..
The gen 3 have never been recommended in the owner manual to have a 0w-16..
There is a couple of reasons I did the switch to 0w-16 anyway:
1. It is not that far of a jump in viscosity to begin with.
2. The 0w-16 did not exist 2010. So Toyota could not specify it, when it don't exit..
3. The same Prius gen 3 engine is used in gen 4 there they specifying 0w-16.
4. And and I am a oil geek since 30 years. 😅
It went well and it seams to work super and the gasoline usage seams to begin going down also.
My take on it is that viscosity is not as important that it used to be..😅
In the old days the additives were not that many and as good as they are today..
So we needed then to more than today relay on viscosity so that higher viscosity at 100°C were that engine protection.. With higher viscosity.
Today viscosity is less of an importance when the additives are far better that creates that protection that higher viscosity did on the old days.
And the base stock oil today is probably that thin so that we can deliver the additives in a more timely matter.
And probably that is more important than anything else nowadays.😅
It’s always 10,000 miles when the dealership pays. It’s 5,000 miles when it’s on your dime.
Well said
You still paid for the 10K change. Why do you think these rigs have tripled in price?
Long service intervals look good when selling a car as low maintenance, though they may not be that great for the vehicle in practice. How many engines have timing chain wear problems these days? Changing oil at 5,000 miles may not guarantee you never have problems, but it is better for the engine than waiting for the oil light.
This is because when you pay, they usually sell you 'conventional' oil, which is a 5K mile oil. It's not the same they use when you are under the free oil changes. Unless you ask for Synthetic oil, then it will be 10k mile. But, it is more expensive.
Uh, use the good stuff, e.g. Mobil-1 or similar, and change it every four to six months? (NOTE: This is when you’re only driving a hundred miles or so per month, with at least one session per month where the engine gets warmed and stays warm for an hour or two, e.g. “bill-paying and groceries, about forty miles at 25-40 miles an hour on longish surface streets with little stop and go traffic.” Not quite the “ninety-two mile oil change” of mid-seventies Mad magazine, but under a thousand miles per instance.)
Toyota tech seeing Lake come in with his daughter's car-"Oh man, we better use that 0W-8 on his because he is going to analyze it for sure". LOL
Well I don’t think they could have stocked it because they knew he was coming. It had to already be there.
😂😂 That's exactly what came trough my mind too. The garage knew that there was no time to play with the oil type
I’m not into conspiracy stuff like that. They may not even know who Lake is because they’ve got so many people working. The vehicle is in his daughter’s name.
But who knows they may have something written in the notes in this vehicles file if they should find out. It’s a possibility. Yet I highly doubt it!
It comes down to the individual dealership. A lot of them will not use OEM oil and just use the cheapest synthetic oil they can buy in bulk or a different OEM oil from one of their other brands that is cheaper. Prime example, the Toyota dealer I bought my 2019 Tacoma from used Ford OEM oil because they were also a Ford dealer and that was the cheapest they could get. The Toyota dealer I use now since I moved uses Toyota OEM oil as they are exclusively a Toyota dealer
@@mrvwbug4423 I think Motorcraft is still Citgo.
I have the same 0W-8 spec’d car that I took to the dealer for the free ‘Toyota Care’ service and I asked the service advisor what oil they put in it. She didn’t know and had to ask her colleague who said 0W-20. I said “Are you sure, because the sticker on the engine says 0W-8.” She said “We don’t have that but can use 0W-16 if you want” So I walked over to the dealer parts counter, who had 0W-8 sitting on the shelf. Thankfully he told the service advisor they could use it for my car.
I’m guessing the average customer gets whatever oil is most convenient for the dealer. When someone comes in and hands them an oil sample bottle to use I bet they call the boss, who tells them to make sure and use the good stuff on this one!
LOL, good point.
Dealers aren't as bad, but Most places are hacks and give everyone 5w30 dino oil.
Most don't even change the filter.
Using an oil with higher viscosity, will increase fuel consumption, right?
Good thing you were smart enough to check with parts dept and not accept what the, clueless, Service Writer had to offer.
I would imagine they have a pump and dont even normally use oil from jugs.
I have the 2024 Corolla Hatch. The American manual states to use 0w-8 and 0w-16. However the Australian manual says that you can use 0w-16, 0w-20, 5w-20, 5w-30 and 10w-30. From what I read, the lighter oil slightly increases fuel efficiency which is required by US law
You are on it!
Interesting! Is it a myth then about the different API starburst symbol on 0W-8 & 0W-12 products to show it is not backwards compatible with 0W-20 through 20W-50? I heard that engines designed for 0W-8 and 0W-12 have different bearing finishes. So that's not true?
This. It’s strictly a tactic to meet CAFE standards. Has nothing to do with longevity or “tight oil passages” engineered for 0w-8. It’s not. Thicker oil is fine.
You better of using 5-20 or 5-30
I agree
They are not manufacturing different engine with different tolerances in 2.0l f example for Europe and for USA!
That would cost alot..
As far as I know the CVT Transmission fluid cannot be completely drained from the drain plug. Additionally from the evidence I've seen the transmission fluids only last about 60,000 miles at most. They go from red to black so I don't believe the story about them never needing to be changed. I also believe there should be a law against making the fluid level so difficult to check it's almost impossible for the owner.
Planned obsolescence Baby….
they got a big lobby
VERY few people even know that a CVT needs frequent oil AND filter changes. Some manufacturers recommend servicing between 30,000 and 60,000 miles, depending on driving conditions. I don't know of anyone who rebuilds them, and they all have very short warrantys!!
@@bradhuffjr777
Nissan infinity cvt transmissions had issues.
Maybe the fluid is more expensive than the transmission?
@@thisisyourcaptainspeaking2259 it isn’t. i have diy serviced my toyota cvt along with the filter change. The fill port is behind the wheel and getting the right level is bit of a process but still easy enough.
No speculation on this channel, all science. So many myths that have been engraved in our minds for decades regarding engine oil and you are dispelling them. Excellent work Lake.
Thank you!
Still a little, to be truly scientific you needed a control, where you did the changes exactly per the mfg and compare the results
I use Castrol 10W-40 for my 1989 Mazda, changed every 5000 km's since new; just did a borescope of each cylinder after over a third of a million km's and the bores look like new, not a mark on any of them.
CVT note: if you have a planetary gear-type CVT, it may call for ATF, instead of CVT fluid, just be sure to check the owners manual.
I stick to oem fluids for CVTs. Not going to risk a 5k trans to save 40 bucks.
Not sure what type of CVT my 07 Prius has, but it can use plain old Valvoline MaxLife ATF. Same stuff I use in my 07 GX470 which has an A750.
@@VuickB6The Toyota hybrid CVTs use a planetary gear set. It's pretty cool! The engine drives either the ring gear or the planets, the electric motor powers the other, and the output comes from the ring gear. So, depending on the speed of the electric motor, you can set the engine RPM and essentially have any output speed you want.
The belt CVTs are the ones that need the special fluid, but since yours is fully geared, it takes ATF.
Best to stick to whatever the manufacturer says to use, and in fact, would just buy it from the dealer. It's the one thing I would say you're best off just paying the extra money for the OEM stuff. Besides a few quarts of CVT or trans fluid in general is far cheaper than a new transmission down the road. I mean how often do you change your trans fluid? Maybe once every other year if you have a CVT (say every 30k-50k miles) and perhaps every 5 years (or 60-90k) if you have a manual or traditional (geared) automatic. And if you have a CVT you should be changing your fluid about every 30-50k miles anyway for best longevity.
Just watched you on Dave's engine shop in utah. Great advice
Me too, Two High achieving individuals 🇺🇸👍
Saw Lake there too!
Thanks!
Everyone should watch that.
Me too !!!
Some Toyota hybrids take regular Toyota ATF. They use 2 electric motors and a planetary gear set to change the gear ratios rather than a belt or chain. Super reliable and durable
Ok you’re talking about the Hybrid not the gasoline motor only
@@AB-yc1np as far as I know, yes. The eCVT trans is for sure belt/chainless, but I'm unaware of Toyota's gas only trans construction.
eCVT
@@ElPants21 the two are different. The eCVT in the hybrids is incredibly reliable with countless examples having well over 200,000 miles. The CVT in the standard gas powered vehicles on the other hand, I have not seen any that are known for their reliability regardless of the manufacturer. Subaru, Nissan, Mitsubishi, Honda, Toyota, it doesn’t matter. Some are slightly better than others, but none carry the same reliability as the eCVT.
This. My 07 Prius uses the same Valvoline MaxLife ATF that my 07 GX470 uses with no issues. ✌️
I'm still sceptical of any filled for life claims.
Me too!
Life of vehicle is usually only 100,000 miles for most manufacturers, so... 100k is what you can expect.
It just means the life isn't as long. The oil life didn't get longer, the transmission life just got shorter.
@@cup_and_cone Or change the transmission fluid every 30k miles and the car may last 50% or 100% longer...
Why. There’s no legal length on life. They’ll just say sorry that was its life, but you can change the fluid now based on our specs lol. I think in the manual by the lifetime fills they should have to put estimates of their interpretations of lifetime at the very least.
It's truly a breathe of fresh air to see someone with a channel that has actual scientific data to explain what is happening instead of speculation and conjecture. Would you ever do an episode or maybe even a series on engine oil additives? Specifically Liqui-moly Ceratec. Thank you : )
Hells yeah
Lake is doing a great job bring many oil myths to light. I threw him a shout-out on my channel and I’m in the process of doing the same mileage test on Costco oil.
Thank you so much!
He's like a wise Wolf 😊
I trained as a mechnic and also spent many years on the superbike racing circuit. We experimented on fully synthetic low viscosity oils and found them wanting in maintaining a sufficiently safe hydraulic wedge. Many journals both crank and cam were lost as a result. It's your money, but I would stick with a decent 5W-30 even if it means marginally higher fuel consumption.
You are totally right. An engine takes on a greater load than a sewing machine.
My 2022 Ram with the HEMI is specced to run 0w20. After 30,000 miles of 5,000 mile OCI, it developed a tick at cold start. No. I swapped it out to 5w30 and started doing all of my own oil changes. The cold start tick disappeared and I have not seen any measurable drop in fuel economy(average 21-23 mpg on the highway, hand calculated). I’m convinced that, for this vehicle, 0w20 is just for that slightly improved fuel economy for EPA ratings.
5w30, greatest human invention ever
@@BF1-P0W-40 ist better!
Funny how you turned your daughters car into a science experiment
I still remember using W20-50 Duckhams Q in early Minis in the 60’s, the oil was green in colour.
You can still buy Duckhams Q 20W-50 (it's now API SJ in the UK) and it's still green in colour! They do a Q 10W-40 too, which replaces the old Q 5500 (10W-30) oil.
My box goes on about this all the time he said it was recycled oil
You mean gear box lube?
@@thisisyourcaptainspeaking2259 the Mini gearbox lived in the engine oil pan, so it was engine and gear oil.
@@chrisbarnes2823 Makes sense. I only had the opportunity to spend quality time with an mg that had no roof, chrome bumpers and no rust. I really wanted that car.
I will never go 10k between oil changes. I wouldn’t be able to sleep at night. Oil is cheap, engines aren’t.
I feel like my issue is if there is a oil/coolant/gas leak into the oil you will not find out until its way too late. So even if the oil can last that long there are still other issues. A good user will check and find those things but I feel like a lot of people will be lazy and never know until their next oil change.
He didn't
@@pleasedontwatchthese9593Just smell it on the dipstick each time(fuel) any significant water would make it milky.
your probably using the wrong oil son. i let my oil analysis of my motor oil tell me if its good or needs to be changed. your a dumbass if you do the factory recommend internals. HELLO!!!! they dont want your car to last because they want you to buy a new one.
Sure thing. You can see why van operators push it out to the 20k miles / 30k km though that Fiat (Dodge), Mercedes, Ford, Renault etc say (with e.g., 2.0L turbo diesels), as they want to keep the costs down. Plenty of people see that this is what it says for their passenger car Mercedes C300 diesel or Renault Talisman diesel as well and just follow it too. In theory this should be OK as long as the oil stays in spec and doesn't get diluted with fuels, though these Euro engines following these schedules do tend to be varnished up when they are opened up.
I love this channel so great to see real results!!!
Thank you!
One of your early subs. I love your videos. We bought a 2024 Corolla Cross and followed your advice. First oil change at 1,000, second at 3500. Going for our first dealer service and we will do an oil analysis and CVT analysis. Thank you so much!
What anybody tells you on any media channel is suspect. The vehicle manufacturer guides you on proper maintenance. They know more than anybody . That said , changing your oil more often will not hurt the vehicle. Just keep in mind that a new vehicle may have special oil to help break in the engine. I would not change the oil after 1,000 miles on a new vehicle. Any metal flakes will be filtered out by the OIL FILTER . JMO
Those first 2 are the most important. Same for trans and differentials. I do those around 12K. 10 if any significant towing.
@@rayRay-pw6gz "The vehicle manufacturer guides you on proper maintenance." Wrong. They guide you on maintenance, not proper maintenance. Case in point, BMW recommending 5,000 mile oil change intervals in their engines that have disposable rod bearings. The results are not shocking, the bottom end comes apart at 60,000 miles.
@@bubbleman2002 Toyota has never let me down . 2018 Camry. The best build and engineering of any vehicle I have owned. 2.5 L. 203HP 8 speed auto/manual . Solid platform and perfect suspension. Fun and comfortable to drive. This is a drivers car. With great safety features. 6,700 redline . I change the oil at 5K or less.
Thanks for sharing, Lake! I enjoy your content.
At this point I’m convinced we’re gonna go back to straight weight oils since I’m sure they’ll eventually make 0W-0 Oil
Just use water
LOL
As far as I know 0w16 can already be a straight weight oil since it’s representing two different scales. The Valvoline offering seems to be close.
Yeah that's the weird part, one of the benefits of synthetic is having a larger viscosity range. But 0W-8 is 1/3rd of conventional 5W-30.
You made me laugh. Thx.
It is always interesting listening your explanations backed with data.
Lake, your content and topics you cover is always top notch. Super interesting and useful to know. Thank you so much for all your hard work. I am always impatient to see more videos from you! God bless
Thanks!
I’d never wait for 10,000 miles! Agree!
The videos you make on this channel are so important for consumers like myself that are a bit obsessed with trying to make sure we keep our vehicles running the best we can for as long as we can. I really appreciate you taking the time to make them.
Thank you!
that’s awesome we spoke on the phone just before New Years I have a 2021 Toyota Corolla Se, amazing information and great video
*clutched my heart and winced after reading "-so it's time for the first free oil change at the-" and not reading "i did first oil change super early due to engine break in shavings" edited: thank god right after i continue playing the video i found out you changed it twice already.
LOL
Wait a minute! You son of bitch!😂 just when I let me guard down after work day. It's still April's fool. Legit thought to myself "what's next, 0w-0? -1w-(-1)? -1w+1?😂"
Amazing Dad. And great technical analysis 👍
Thanks!
What a great dad you are, looking after your daughters car like this. 😊
😊 thank you
Thank you for addressing transmission fluid change.
Hopefully you have more information.
CVT transmissions can work well as long as you know what you have, fluid needs changed every 20,000 miles, the Jatco transmissions have 2 filters, one in the pan, the other where the cooler lines come out, make sure both are changed, also they will not stand hard driving, that is why you will only find them behind low power 4 cylinder cars, so drive easy and get the fuel economy benefit, never let your 18 year old son borrow it lol
Way back when, I used 20w50 oil in everything and it seemed to work great. Over the years it has been hard to adapt to the ever-thinning viscosities. I am struggling with the 0w20 requirement in my newly-purchased 20011 FJ Cruiser and now they come along with ow8! Your extensive testing is helping this aging gear head adapt to a new reality.
cus engine tolrances are much tighter now. old 60s 70s 80s where horrible specs, lots of slop in engines. things do improve. If you use too thick on modern engines you will cause damage, ever think the makers know what they make?
@@cengeb That's very true, but I still would be extremely skeptical to run anything less than 20 weight in anything that's going to haul or tow. Too much stress on the drivetrain to depend on sub 20 weight oil keeping parts from touching.
Also, manufacturers aim is economy not longevity so v thin oil may not be in your best interest.
@@bobbygetsbanned6049 Thanks for this! I say that because I have the lowest power, production car in America. The Mitsubish G4, and it revs a lot more, it's built for that, but I wonder if just pulling itself, is why they went with 5w-30....but it also makes me consider that they've made them similarly for so long, that maybe the cheapest car in America, which is going away by the way, that maybe, just maybe, they haven't built them any tighter or newer, so they were wise enough to still insist on 5w-30. Sure, cafe keeps pushing the limits, but since it sips gas, they didn't have to compromise on the oil choices.
@@cengeb THEY ARE NOT TIGHTER SINCE 2000
Awesome video. Very interesting the lower viscosities are going.
Thanks! More to come!
I love the idea you have about testing the oil at different intervals. I'm curious to see how well the oil is doing at 10K miles.
Great video - watching your others!
I'm a huge fan of these videos! Extremely educational and on a completely different level than most others on RUclips. 👍
Glad you like them!
My wife's Subaru calls for 0-w20. It started burning oil at 120,000 miles requiring a quart every 2500 miles. I switched to 5w-20 and it hasn't burned a measurable amount of oil for 80,000 miles since.
That's cause subarus seem to only call for 0w 20 in the US I have a new wrx an it say 0w 20 but in Japan Australia an Canada manuel says 5w 30 it's emissions crap they don't care about the life of your engine
The W number is strictly a cold measurement, it's likely something different between the two.
@PSA78 they recommend 5w 30 so they want higher weight in cold an hot also higher weight oil you get less blow by on these di engines so less intake buildup
@@JoshDillon-lm3hw It's not "weight", the W(inter) is just a measurement of cranking force at a specific temperature (really low) and the last number is regular viscosity (span) at 100c (converted to a number for each specific type of lubrication; like engine or transmission). The W number can theoretically always be reduced (diesels sometimes excluded practically as they don't like the high amount of viscosity modifiers that might be needed).
How much oil they burn is more down to how volatile the oil is, a small change in viscosity isn't going to matter when all things are considered. There's possible wear reductions with lower viscosity as well as the additives works more efficiently in mixed and boundary lubrication regime, it all has to come together in the end.
It's like Lake says, let the UOA tell what's happening
@PSA78 the numbers are the weight of the oil lol weight is what viscosity was to called the last hundred years why people who don't know oil think that's what w stands for
It would be very interesting to get your take on the new Valvoline restore and protect. It claims to be the only oil that actually removes deposits. If it does what it claims, it would be great to clean coking from oil control rings on DI engines.
I would bet that adding something like Marvel Mystery Oil to your engine oil achieves the same deposite removal results at a cheaper price point.
I've asked in another video for him to do this as well! I hope he does
@stephenh809l2 lol
It's not going to clean deposits from the intake ports on DI engines. And coking on oil rings is not just a DI thing that is most modern engines as they all have low tension oil rings now. I've only seen two design solutions that reduce or eliminate the intake deposits on DI engines, either dual DI/port injection like Toyota D4S and the newer Ford EcoBoosts or water jacketed intake ports like Mazda has on the SkyActiv engines.
Stay tuned! We are going to do an in-depth video on the Valvoline Restore & Protect.
RepairGeek recommended your channel. Great educational video’s your sharing. Appreciated ❤
Loved your interview with Dave Auto Center 😊
Thanks!
Toyota Hybrid CVT is a e-CVT and dos not have a chain. It has a planatery gear set and 2 Electric motors.
I heard the hybrid CVT is indestructible
That CVT has a first gear. The engine uses Toyotas D4S system, it has both port and direct injection.
Seems like the most reliable way to do it, by using a standard gear set for getting the car moving to eliminate stress.
Toyota is the KING of making cars that work well and last long. I ❤️ Toyotas 😀💕🚗
Thanks Lake. Great job. Good info. God bless. Happy trails.
Thanks!
i love your videos please just keep doing them
Thanks!
Thanks for all the videos. I really enjoyed them. Have you analyze Super Tech oil? Is it any good?
Stay tuned! We are going to feature that in a future video
I really rock the boat on my DIY oil changes. Use Shell Rotella T6 full synthetic 5W40 diesel oil in my 2007 Volvo XC70 with turbocharged 2.5 liter gas engine. Change every 5K and doing fine.
Awesome content - thanks Lake!!!
Glad you enjoyed it!
Thanks Lake Speed Jr!
Really enjoy your “daughter’s Toyota saga”!
Nice car btw!
Yes, I was scared of the low viscosity 😅
Maybe I can put that 0-w 8 in a ‘95 powerstroke if it reduces wear even better that regular oil, due to it’s top secret super sauce! 😆
I have to agree Lake that when you monitor it by samples you get the real data. My gut feeling is telling me to stay away from this water thin oils but the data show otherwise. So i have to adapt my auto mechanic brain.
Thinner oil is needed for tighter tolerance bearings. Tighter tolerance bearings wear less and last longer.
@@deelowe3false. The only real reason is tighter emissions and mileage requirements.
@@deelowe3 These Toyotas do not have tighter tolerances. That's an urban myth. These thinner oils are driven by C.A.F.E. standards pushing for ever more MPGs. Nothing more.
In Australia the exact same engine is allowed to use oil even up to 10W40. Do the Aussie Corollas have lesser bearing tolerances?
Tolerances and design clearances are two entirely different things. Manufacturing tolerances have improved over the years, but engine bearing clearances are determined by factors outside of oil viscosity.
@@pete1342 You're right. I meant clearance, not tolerance.
The issue with the corolla cvt service, at least the prior one is you only get something like 1.5 quarts to drain due to the location of the drain plug on the pan, it holds about 8 quarts. There are 3 or so magnets in the pan no need to worry about service for a while. Best/most cost effective way to service is drop the pan, clean the magnets and replace the gasket. Or use a flush machine but 12 quarts of toyota cvt fluid is expensive, and the fluid level still needs to be set/verified after flushing.
Man I didn't know ornl was doing research like that. Cool video and surprising info.
Glad you enjoyed!
A greatly appreciate your Channel ,you do a great job
Thank you so much 👍
Thanks for the video, appreciate the topic a lot because I personally feel very bad using thin oils.
As a Toyota dealer technician in Europe, I can tell you we use 5W-30 in this exact engine, and on basically all the other common Toyota models and engines.
We only have 0W-20 for the 1.2 4 cylinder turbo (8NR-FTS engine), thats as thin as we go.
Oh and by the way, we don't even use OEM Toyota engine oil, just some generic brand (with Toyota specification approval) which is still mindboggling to me since the oil changes are not so cheap
I can assure you, dealerships buy bulk oil from whoever gives them the best deal with the best perks. The Yota dealer I used to work for built a new building and Quaker State bought them two Rotary lifts and gave them two NASCAR body go-carts to get the contract. The GM dealer was using Kendall, Chrysler/Dodge/Jeep was on a Valvoline contract. They are not required to use a manufacturer’s oil. Hell, tons of places use BG for their trans flushes.
I haven't worked with CVT's much, but normal gear shifting transmissions definitely do better with BG. My manager at Chevy was working hard to get BG products going and the data and studies were very convincing. The BG work for CVT's, I'm told was better too, but it's been some years since I upgraded my life from being a mechanic, got into IT, but if AI takes a bunch of jobs, maybe I'll have to work on cars again. LOL Nah, I'm top at my IT experience level so that should add some safety for a while, especially since I can do a lot of hands on work that much of the IT industry can't do.
Tell me who, other than a mechanic is going to figure out that the wall socket is dirty (clean on the outside). We have so many more variables we're usually fighting than with computer building. I hope they never get into computers like they did cars, intentionally making them hard to work on, but if they do, my automotive background will be huge. LOL I guess the car equivalent is bad gasoline, which happens most from customer errors.
Can depend. Dealership I work at, Dodge size uses bulk oil, chevy side uses bottled genuine ac-delco oil.
@@LovesHina It’s up to the franchise owner. It’s interesting that the owner is going through the heavy profit loss of using individual quarts, and on top of that rebadged bulk oil sold as AC Delco. I assure you, AC Delco does not own a refinery. Who knows what these owners think.
@@blackhawk7r221 I also find it a bit strange, as it does add a non insignificant amount of trash, and time to each oil change as well. I assumed it's a GM/Chevy thing, since they do have a few varieties of oil for different applications. Dexos 1, dexos 2, Dexos D.
@@LovesHina With the way the LS cams were being eaten up a while back, this may have been a measure to ensure that a legit factory approved oil was used. I doubt it, but like I said, we never know what’s going through the minds of owners. I’ve seen them do some oddball stuff.
Not our 2022 Toyota Rav4's 1st oil change here in Honolulu at Servco Toyota. It was 5,000 miles but the dealer said no oil change, only at 10,000 and 20,000 miles but I used the 10,000 mile free oil change. Instead of the MFR's recommendation of 0W-16, they used bulk 0W-20 oil. I did my own changes after than using Mobil 1 Advanced Fuel Economy 0W-16 and Toyota's OEM filter.
I really like your videps and I appreciate the information. Have you ever reviewed Valvoline Maxlife ATF?
I had heard that the newest Corolla CVT's have a conventional 1st gear and then CVT for the other "gears", but I haven't confirmed which engine comes with which CVT, etc. Thanks for the great info!
Yup that’s right. New Toyota/AISIN CVTs (not ECVTs) have a launch gear.
Love that series.
I wish you did one on selecting an oil for a used car.
Great suggestion!
@@themotoroilgeekyes please, specially for 90s to 2000s TDI engines with north of 250.000km.
I've been running 5w40 since the beginning :-)
Amazingly good content Sir.
Holy moly this is the first time I’ve hearing of these type of viscosities
I’ve watched several of your videos and I respect your knowledge and expertise. Let’s say for purposes of this discussion, you are right about all of it.
For me, and for most guys who buy and use cars in an average way, none of it matters. I’m in my 60s and like lots of other guys my age, I’ve owned lots of different vehicles. I’ll sell a car when I don’t need it, or don’t like it anymore, or sometimes too many little things go wrong with it.
But it’s been a long time since I owned a vehicle with engine trouble. Todays cars and trucks run a long time with just a little bit of ordinary maintenance.
To the guy who buys new and wants to keep it past 300,000 miles … To that guy, if he exists, what you say matters. To the rest of us, buying and selling on the front end or the back end, we’ll never get a reward from persnickety oil maintenance.
That said….i enjoy the videos!!
Thanks for the comment. Maybe in my world of engine building we see all the failures, so our vision is different than the ordinary customers.
When I'm in my 60's I'll be grateful for my picky oil and filter selection, 5k OCI's, and rabbit holes on rust-proofing, when I'm still driving my '18 Camry and hopefully '12 Civic LX MT. I hear ya though! LOL
1999 4Runner. 10,000 oil change interval, factory filters. 513,000 miles, runs great.
What oil?
99 4runner had 10,000 mile intervals?
@@DaDaDo661 Yes, I did 10,000 oil changes with 5W-30 mobile 1 oil and Toyota factory filters.
I also never missed a spark plug change every 30,000 miles, again with factory plugs
🧢
I appreciate the confirmation that the manufacturers know what they're doing. I hear so many people accuse manufacturers of giving bad advice to make you ruin your engine so you have to buy a new car. I bet what is actually happening is that people use cheap oil and then run it for 10k+ miles...
Wow that's surprising that the dealer actually used the specified oil!! I've had cars where the dealer didn't use the recommended oil unless you explicitly told them to!
Love your videos! Will be using your oil analysis to see how my Toyota vehicles are doing, I’m a firm believer of oil is cheap, engines are not😂
Rock on!
Cool video! It would be interesting to see how these new ultra thin oils perform against traditional oils when both are using the same type of base oil and additive package. While it's cool to see that a 0W-12 can perform as well as a 5W-30 in a lab test, it would also be great to see a true apples to apples comparison with the only difference being the viscosity.
Great suggestion!
@themotoroilgeek please do a series or video comparing the amsoil levels like you did Pennzoil! I love seeing these details so I can make the best decision on my 2019 Civic Si. I plan to do big mods with it but for right now it's been my daily since I got it brand new in May of 2019. Thank you for your videos and science behind these oils!
Nice! I had that same oil sample pump when I used to work on rotary air compressors
Right on
Back on the farm, the combines we ran had variable drive on them as well, but it wasn't directly in the transmissions. Our International combines had a regular 3 speed transmission, then had a mechanically actuated belt drive on the side of the machine that gave almost infinite ground speed. Granted at top speed in 3rd gear, it maybe went 12 mph specifically for highway use, but the field speeds were pretty much miniscule adjustments. 1st and 2nd were the field gears and you operated the variable speed either by a hand lever on the floor or a foot lever depending on how old it was. It made for very easy forward motion control without changing the engine speed. The machine thrashing speed had to be maintained at a constant speed so changing ground speed has to be done separate from the engine speed and it's cumbersome to change gears. It worked fairly well.
Our newest combine had hydrostatic transmission where the ground speed was contained within the transmission and actuated by a hand lever on the steering column. It used the same process to increase or decrease speed but it didn't have the big belt drive on the outside of the machine. It also didn't have a reverse gear, the hydrostat had the ability to move in reverse in whichever gear it was in by just pulling the lever back to the neutral position which stopped the forward motion, then continuing to pull backwards on the lever and the combine went in reverse. The variable speed combines did have reverse and the variable speed mechanism did operate in reverse too.
It's kind of interesting that they modernized the process and put it into transmissions in modern cars. Subaru also has a CVT transmission too.
If those lower viscosities can still protect under load, the big benefit will be much faster pressurization and protection at startup, especially in colder weather.
Really dig these videos. Have you done or plan to do a video on time frames for drains ? I have an old Corolla that I barely drive and try to change the oil 1 time a year.
Stay tuned!
My Honda 1.5T CVT transmission i changed it @ 15K & 30K worked fine & i drove it hard & it was tuned. I think CVT is decent u just gotta take care of them.. change the hell out of the fluids lol. 🆒 video. Thanks 💯
I feel like you are the right person to ask this and I would love to see a video on this as it seems no one is in agreement. Techs believe 3-5k is max even with advances in technology while OE’s are pushing that 10-15k while aftermarket’s like Mobile 1 and Amsoil are pushing 20-25k. Obviously the question is quite load and dependent on many variables but with everyone is disagreement it’s hard to come to an educated opinion
At 49 yrs old, and owning a shop, working dealerships, just 25 yr recert ASE Master +, having loyal customers nearly 20 yrs in my shop, I can give proven, experienced advise. Stick to around 5k miles. I tell certain ones with newer cars they can stretch a little if they have good driving habits. I get to see their oil when it comes out. Personally my vehicles all go 3-400k miles on original engines. I stay between 3-5k max. Because I know my driving habits. lol. 80's to mid 90's get 3k on the sticker. ALL others get 5k unless they demand otherwise. I generally rotate every time now. I switched to full syn oils back about 2010 (syn-blend about 2006) for all vehicles and never used cheap filters. Mostly OEM. Don't like it? Go somewhere else. I'm not an oil change shop. I only do oil changes for my regulars so I can monitor for other upcoming issues. A 5 quart oil change is running about $84 total May 2024. But how many have a $100/hr tech changing your oil and checking everything over at that time? Not many.
Cars rust. 10k oil changes are fine. It will rust first
Hey! Love your channel man! I was wondering if you could make a video between fluid recommendations from the 70s compared to the more modern fluids available nowadays; For example SAE 50 and 30 that used to be recommended for Differentials/Transmissions/Transfer cases and the newer 75w90 and 80w90 more modern gear oils. Can modern fluids be used on older applications (70s fords, gmcs and such)?
Great suggestion!
Got my results after this commmercial…. Wild timing
Man, for a second, I thought you really went over 10,000 miles without changing the oil! I've been doing mine every 5k with Mobil 1, but recently started doing it every 4k.
the way i see it is they are to meet EPA requirements so if 0W-8 works for 100K miles and the engine wares out that's the problem of the sec or 3rd owner.
and 10k mile oil changes are ridicules 5k max.
I had the dealer change the oil in my 2023 RAV4 at 1,000 miles, and then six months later, I brought it back for another change at 3,000 miles. My Toyota dealer surprised me when they said this one was free based on the date and not miles. They also rotated the tires. (Love the fluid sample pump)
Thanks for sharing that tidbit!
I just bought a Mazda CX-90 and asked about the free maintenance for a year. They couldn't give me a straight answer on how many times I could change my oil in a year or if it was based upon mileage
@@TheBasscow@TheBasscow Please listen to Lake Jr. and change it between 500 and 1000 miles the first time and every 5,000 or six months, whichever comes first after that. Pay if you have to because it's worth it.
i hope you check to make sure they actually changed it. dealerships check the oil and mileage and if the oil looks clean they dont change it but they pretend they did
@@cantwealljustgetalong2 I saw my RAV on the lift and draining the oil. I hope my Toyota delaer would never consider something so dishonest.
Thanks for the info! I recently took mine to the dealership I bought it from and after debating with them that I wanted an oil change at 1k they agreed . I had to pay out of pocket no biggie but they put 0w16 gtmo back in it. I asked if they had the 8 and got told they 16 was perfectly fine and so on. Do you think running the 16 will have a negative impact long term?
Great video, as always.
Really interesting.
Is your daughter’s warranty on the car void if you’ve serviced yourself?
Not at all. As long as the correct oil is used, doing an oil change yourself does not void the warranty.
Not if you don’t tell them it’s not
Love this geeky stuff man, keep it up.
Don’t think you got any special treatment?
Maybe would have been good to send your daughter in with the car lol
LOL, I don’t think they know who I am.
Lake your advice about cvt fluid was a hallelujah moment for me. My cvt calls for Toyota tc fluid but most out there seem to be universal fluids also covering later cvts requiring lower viscosity fluids. Other than genuine Toyota fluid, I can only find one fluid in New Zealand which only covers up to TC. It's the one I'll continue to use.
I would enjoy a future video on oil additives.
Filled for life means until it breaks. I'd still change the trans oil every 30k.
On a CVT, I AGREE!!!
💯💯💯💯
Filled for life means until the warranty expires.
LOL
Man, you almost got me with that 10,000-mile first oil change 😅 I was like Motor Oil Geek let his daughter drive her car 10k miles without any intermitted oil change?! What? Hehe. Thanks for the informative video.
I think car /engine manufacturers 'thin' the oil cuz the start-stop function to make the engine start easier, higher efficiency like less oil resistance/drag, and the even more strict emission
LOL, the fuel economy benefits of the thin oil is what makes them spec it.
@@themotoroilgeek0w30 (Mobil is the only one with this) literally disappears on bigger engines with looser tolerances. 5w and 10w30 is much less respectively. Even in winter, any mileage gain (couldn't see any) is way offset with the need to buy so much more top off oil.
They’ve had start stop for years now and no it has nothing to do with the engine oil being easier to start not sure what made that go through your mind the actual reason in MPG that’s the only reason. There’s a lost efficiency in pumping and by splashing the thicker oil but it breaks down much quicker if you look in any book from any manufacturer they all recommend a specific weight but will always have a chart in it for using other weight oils mostly thicker too
@@inductionbyforce8656 so what I wrote is the same as you repeated but with different words.
What do you think less oil resistance means? Less drag, quicker oil pressure build, smaller tolerances on rings, pistons, bearings, etc. Splashing is nonsense, many cars for many years have oil baffles/windage trays to prevent oil splashing onto the crank...
What do you think efficiency means? Higher mpg or in Europe less liters/100km, higher thermal efficiency.
What do you think more strict emission means? Maximized amount of CO2, Hydrocarbons, NOx, and particle emission of an exhaust. Emission limits have essentially halved from EURO 5 to EURO 6. This is the drive for the innovations and engine efficiency to increase (downsize, forced induction, hybrid, using flame speed manipulation). You should also know that a vehicle manufacturer has a total annual emission limit also per manufactured car models/engines, look it up.
I am using simple words because of other comment readers, to understand it easily, not to read words that they do not know how to pronounce, let alone understand.
The trick to see what oil you should actually run in your car is to check the manual in different countries to see what oil is listed. Most of these engines arent actually made for the thinner oil that is called for in the usa.
Its just for mpg improvements and there so small its funny. I would never put anything less then a 20 weight in.
Manufacturers can always put those "great" additives in there 8 weight oils in the heavier weights 🤷♂️
Being that you’re a Porsche owner, I’d appreciate if you do a video on the Liqui-Moly oil from Germany. Appreciate your informative channel.
In the Netherlands the Toyota dealerships do not use 0W20 in the RAV4 Hybrid (2015-2018). They all fill them up with 5W30. 5W30 is also approved by Toyota but for the lowest fuel consumption the factory advises 0W20...
Меняю масло в двигателе каждые 5000км(летом), а зимой каждые 4000км(из-за прогревов). И никаких проблем с двигателем! В автоматической коробке меняю жидкость каждые 30000км, заправляю полный объем методом вытеснения! Живу в Сибири, в ста километрах от Байкала!

Brrrrr! Stay warm.
That sounds good. Maybe change the oil more often in the winter, cold oil flows less easily, and how hot are summers in Siberia? Surely not as hot as southern USA.

So, the manual says you can use 0W-16 but you must replace it with 0W-8 at the next oil change. I was surprised you didn't highlight that fact during the New Car oil change video you did with your daughter's car.
Correct, my 2024 Corolla owner's manual says that, but has the same decal as his under the hood. 0W-8 is now available through Walmart. Mobil came out with GLV-1 approved oil in March 2024.
That's just legalese for the EPA.
I think Geek did mention that in his video IIRC. He opened up the manual and clearly stated that 0w8 was the proper oil to use, but that 0w16 could be used if no 0w8 was available. I don't see how he could have been any more clear than that.
Anything lower than 0w40 is junk.
@@themotoroilgeekYep, all the cert. testing was done with the 0w8 oil.
Been waiting on this one for my new 2024 Toyota Corolla LE. Thanx Lake! Need that vacuum pump for my oil diag test kits I got from SpeedDiag. Back to the website I go...
Great Channel..never knew there are so much additives and what they do..was wondering if you have a video on what the differences are on oil for Turbo engines do they have xtra additives' to fight heat breakdown or turbo cokeing.. Have new CX30 turbo...I do let it cool down for 2 or 3 minutes before turning of the car, was planning on doing an oil change at 1000 miles....was just going to run a full synthetic ..just a bit early for peace of mind...watched your break in video..also a great info...do you have a Favorite oil for turbos?
It's great that the Henricks Toyota Dealer in Concord used the proper quality oils. I don't know the policy of Toyota over their dealers on what lubricants they're permitted to use. But typically dealerships will order in bulk from whatever oil distributor they get the best deal from.
To be clear, whatever oils they use are not some cheap no-name oil. They will get a known quality name brand that we have all heard of. But it isn't always the "OEM" branded product.
I was pleasantly surprised as well!
As a hendrick Toyota Tech, I've only ever seen the toyota genuine oil ordered in bulk, I see pallets of the shit piled in parts every time I go to grab a box, we have pumps for 0w-20, 5w-20, and 5w-30. They use a synthetic blend so I've heard from the older techs, when it comes to off brand vehicles we usually source what they recommend (Mobil1, DEXOS, etc...) if the manufacturer doesn't specify what the vehicle needs then they get whatever is coming out of the pump. My favorite oil I've seen was this green shit we had to special order for a BMW weird euro spec stuff
@@S1Lent_Wanderer Thanks for sharing!
@@S1Lent_Wanderer Good to hear that your dealership makes this effort. Many don't. I know of a Chevrolet Dealer and a Dodge dealer for example that buy the lowest priced stuff in a drum they can get at the time they order more oil for their service departments.
Even then, it is good oil and isn't really likely to hurt anything. I know that the Dodge Dealer gets a 0W/20 and a 10W/30 no name synthetic and the same weights in a conventional no name oil.
10k interval is ridiculous
Very interesting! Thanks!
Glad you liked it!
We appreciate your videos
Thanks! That’s so nice of you.
I mean I know you’re an engineer and all; but some guy named Jim on Facebook says he would never trust oil that thin, so I’m just going to go ahead and use 20W50 on my car
LOL, best one yet!
And not only do you make sure to use CVT fluid in a CVT, read what the vehicle manufacturer calls for. There are a variety of CVT fluid types.
Great point!
@@themotoroilgeek Surprisingly, "Valvoline MaxLife Multi-Vehicle ATF" is a replacement for Toyota WS ATF (conventional shifting auto trannies) AND Toyota CVT FE, yes, both. I think they just added a big list of CVT's to their compatibility List, as seen on their latest Product Information spec sheet. Since that stuff is very well respected (runs in about any automatic around, with good shift quality!!), I would not doubt the Valvoline "experts" in claiming this universality (kv100 5.9 cSt), and I guess the frictional characteristics work in conventional style AT clutches and CVT chain systems too! I don't know how they do it. Heck, it would prob work in my '24 Honda CRV Hybrid e-CVT, but that one did NOT make the list for some odd reason.
Jesus... bless this dude and people watching hearts... wow.
Great content, love the hard science. Would like to see a test on re refined motor oil and the stats compared to conventional and synthetic.
Great suggestion!
