Will 5W30 oil damage my Toyota (2GRFE)?

[@robertwilson5615]

Really good investigation. Thanks. BTW, it's not engineers that chose the 0W-20, it's the people on mahogany row trying to squeeze more MPG. For me, I'd use 0W-20 during cold weather (I'm in NH) and 5W-30 in warm.

[@doublebase6509]

Agreed…and I’m surprised to find that more and more people are starting to realize that the engineers are not making major decisions in the auto industry. Warranty plays a roll and government regulations plays a huge roll. Then there’s advertising, cost of the vehicle and marketing. All this^^^has to be factored in to any findings/suggestions engineers have.

The low tension piston rings will hydroplane on thicker oil. The only thing you can do is keep clean oil in them.

Oil appears to be at the same level at which is was at the oil change. Crazy thing is when I check the oil before the next change, the oil is still relatively clean. Still has the original spark plugs. Average gas mileage between 26 to 28, higher on a road trip. Thank you again.

Wow, I am surprised how much research you have done on this topic. Your research is what I needed to feel comfortable about using 0W-20 on my 2007 ES350 with 2GFRE engine. I just received four 5qrt Kirkland oil shipment from Costco, which tested as good as any other more expensive brands by Project Farm. I actually meant to order 5W-30 as the manual calls for but I accidentally clicked wrong one and received 0W-20 instead. So I was wondering if it would be ok to use lower viscosity oil, which brought me to this video. Thankfully you had all the information I needed to feel comfortable about using 0W-20. Basically it seems to me whether you use 0W-20 or 5W-30, it should not make a whole lot of difference, which is why Toyota engineers specify different grade oil on exactly same engine. What concerned me the most is whether 0W-20 would cause more wear than 5W-30. But, based on your test results, it does not seem to. So I am just going to stick with 0W-20 I got instead of going through the hassle of returning it and getting an exchange. Thanks a lot for providing so much valuable in-depth information I was looking for!!!

I was so surprised to see such dramatic difference. I will never use thin oil on my car any more. I will even use thicker oil, such as, 10W-30 or even 10W-40 as my car gets older and the seals get worn out more. Here in CA, winter is very mild so I can afford to use thick oil. So I think you are doing the right thing by using thicker oil as your car gets older.

[@gzhang207]

The general understanding is to use thinner (or Toyota recommended) oil in the winter and the thicker oil in the summer. If you are in southern states, there is probably no difference if you use the same thicker oil all year around. Your suggestion of using thicker oil for aging engines makes sense too. The trend is Toyota is using even thinner oil, e.g. 0w-16 for newer cars. Why do they do this considering global warming?

[@doublebase6509]

I did consider using (or sticking with) the 0W20 for the winter months, but I decided to run the 5W30 right through the winter. I don’t think it’ll be a problem because the difference between the 5W and 0W at zero degrees is minimal, and where I am it rarely ever gets bellow -10 degrees. At worst my cold temp startups will maybe hit 15 degrees once or twice (I have a garage). Regarding the 0W16, I believe Toyota is now introducing the 0W8 oil (I’m nit sure for what applications, maybe hybrid). But the lighter weight oils were introduced to improve fuel economy, and therefore reduce the carbon footprint of the car manufacturer. The manufacturer is required to produce a certain number of fuel efficient vehicles in their lineup to comply with corporate average fuel economy regulations (CAFE regulations). They’ll try all sorts of things to get themselves within parameters for those regulations, because if they don’t, they’ll be heavily fined. It’s a driving force behind the industry.

I use the Amsoil SS 0W-20 in my 2016 Camry Hybrid that and Amsoil SS 5W-30 in my 2013 Subaru Tribeca (as well as Amsoil SS ATF and Amsoil Gear Oils). These Amsoil lubricants are "100% Synthetic" (without containing a drop of "hydrocracked petroleum," but conversely "hydrocracked petroleum" is used as a main ingredient in the majority of "Full Synthetic Lubricants). These Amsoil Lubricants deliver more power to my vehicles (who wouldn't want that), gives my vehicles increased gas mileage, helps quiet engine noise and extends the length of time or mileage between oil changes. There are verified customers of Amsoil (who have temperature guages in their vehicles) claiming that their vehicles run cooler with Amsoil (as an additional bonus). Since 100% Synthetic Lubricants (a combination of PAOs & Esters) don't contain any petroleum, they are much less likely to have oxygen molecules attach to their molecular backbone of these lubricants, compared to petroleum and hydrocracked petroleum, which contain much more of these oxygen molecules that in turn attracts sludge formation. Amsoil SS 0W-20 oil has a Pour Point of -63 F, whereas Amsoil SS 5W-30 oil has a Pour Point of -58 F (not that much of a difference). Another benefit of these Amsoil oils are a rapid flow through the engine maintaining proper lubricating properties which is due in part to their equal-sized molecules & a lack of undesirable contaminants (found in petroleum and hydrocracked petroleum) allowing less friction. Less friction means less heat, greater efficiency (in terms of gas mileage), more power and more circulation through the engine. A typical 0W-20 oil will flow through an engine more rapidly than a typical 5W-30 oil, so a 0W-20 will help dissipate heat better than a 5W-30.

After putting in a new oil & new filter. Try keeping at a fixed 2000 or 2500rpm, in the middle of a road trip for 5 miles in a hot noon. Note down the oil pressure vs rpm vs water temperature or oil temperature. Repeat this just before next oil change. Would you expect an increase of 0.5barg in oil pressure? Then for the next oil change switch back to 0W 20 with a new oil filter and repeat this test. I just made a verification on my newly installed oil pressure gauge for an 18 years old car having done about 129k miles. Holding it at 2400rpm and oil pressure is at 2.4bar for 5W40 oil.

[@yt-xe8ws]

Zero-weight oils are designed to reduce emissions during warm up. If the wrong oil is in the crankcase, it will change the three to five minutes it takes to bring the combustion chamber up to temperature. This will also alter how the variable valve timing works. It can also have implications for the catalytic converter. Always use the motor oil viscosity recommended by your vehicle manufacturer. Using a different viscosity (thinner or thicker) may cause oil pressure and oil supply problems, especially in late-model engines with cylinder deactivation and/or variable valve timing (VVT).

[@doublebase6509]

Every vehicle runs onboard emission testing every 15 seconds (or less) on every vehicle in America. Test/pass, every 15 seconds. If it tests/fails. It’ll run it again. If it fails again a check engine light will turn for federal emission failure. Plain and simple, if a 5 weight oil made a negative difference in emission control it would fail onboard testing and a check engine light goes on. A lot things happen to reduce emissions on a vehicle, if oil was a detriment to emission reduction a check engine light will turn on. That’s just facts.

I have a 2008 Highlander with 255k miles and I use fully synthetic oil every 5k miles with 5w30 as specified and when the light comes on. 10k between oil changes is too many miles in my opinion. I often wondered about that what changed inside the engine with the thinner oils. It looks like the only thing that Toyota changed on the 2GRFE engine was the oil cap. Lol

[@doublebase6509]

Yeah I might agree with you on the 10,000 mile intervals. It’s something I usually don’t adhere to, but I am experimenting a bit, and it is their recommended interval for ideal driving conditions (which I do almost qualify for, except for the cold temps, but then again I’m not short tripping in cold temps, it’s all long distance). Good luck with your Highlander! Great vehicles!

[@frankbiz]

@@doublebase6509 thanks, yes they are great. If you do a lot of long trips then yes, you can go longer between oil changes. I just changed my oil, but I wonder if it will be ok to try 0W20 on my next oil change if it's still winter. What do you think, I'm sure it won't hurt?

@@frankbizprobably be ok, but keep in mind, your engine is spec’d for the 5W30 and now you have a lot of miles on it at 255,000 miles. Going with a lower viscosity might cause some oil consumption, not sure.

@@doublebase6509 I agree, thanks! 👍🏻

[@SuperMan-uj7dh]

Why would you sacrifice cold start wear protection? 90% of the wear occurs when the engine starts up, regardless of whether it is hot or cold. A 0W-30 would be better. I'm guessing that you will have more wear metals with 5w30. Also, the VVTI issues of these engines were ususally the older ones with 5w30. The gear itself was updated when they changed to 0w20. Maybe you might get the VVTI sound due to thick oil on startup? Idk. I have the same engine in my venza and i never go more than 4000 miles regardless of the oil I use. I used Mobil 1 EP 20000 miles and change it at 4k, recently switched over to Pennzoil Ultra Platinium and the engine noise is considerably reduced. Project Farm did a test and PUP was 2nd, very close and basically a tie with Amsoil. I actually recorded a video after I changed my oil with M1 and PUP, there is a significant difference!

[@doublebase6509]

I understand that 90% of wear occurs upon startup, but keep in mind, you have to start your car (unfortunately), and oil does remain on all metal moving parts even when you shut your engine off, but I agree - engine wear occurs at start up. Regarding the cold starts - 0W protects up to -35 degrees, 5W protects up to -30 degrees. The absolute worst I’ll ever experience in a cold start is 10 degrees (maybe twice a year, max). Car is garaged. The only other start during a day is much later after work, and it’s usually 30 degrees when I do that start. And it’s not about flow, it’s pumpability. The pumpability of both oils when cold is pretty similar. I did consider the 0W30, and I still might use it, BUT the wide spread of a 0W30 will contain more viscosity index improvers, and VII tend to shear and contribute to sludge/deposits. Now, do I think that’s a problem? I’m not sure, kind of doubt it, but it has scared me away from it a tiny bit. Regarding the VVTI system, I’m not sure what you’re referring to. The oil is directed through solenoids/actuators to the cam phasers. There are chain sprockets on the outside of the phaser, where the timing chain will ride on, but there is no gears (internally or externally). The timing is changed/altered slightly by hydraulics (oil), modulation of the oil being directed into chambers of the phaser, where it will effect timing depending on which side of the vane it goes to. It will wear out eventually and cause the early morning startup rattle. Usually at 200,000 plus. I don’t have that. I don’t expect that to happen any sooner or later than anyone else will get it. Regarding Pennzoil Ultra Platinum. Never tried it, but I’d love to. It contains esters and some PAO’s (I’ve read), and for the price, it seems to be a bargain compared to an Amsoil or whatever full synthetic base stock you compare it to. It may be may next oil for sure. I do like Project Farm’s videos but his tests and testing equipment are not on par to real world testing or the testing equipment oil manufacturers have at their disposal. Yet I think he does a great job! And I don’t totally discount what he does at all. Thanks for posting. I love oil talk.

That is silicon not silicone. However I strongly feel that the 5W /xx provides better sheer margins and the 0 w stuff is only CAFE garbage compliance. I would reconsider in -20 temps for that one winter oil change, Not a fan of 10 K changes.

Good stuff, thanks. I’ll make sure I pronounce that correctly next time. I always assumed it was a way of saying silicates, and the “silicone” didn’t make much sense to me.

[@exploringsydneyandbeyond9059]

in australia i’ve used 5w-30 and always will - 0w-20 is too thin and will cause more wear long term . engineers are not always right , they are also steered by marketing and the environmental groups . bearing clearances haven't changed in decades 5w-30 for cooler times and even a 5w-40 in hot summers , along with intervals halved from what toyota says your engine will last incredibly longer . If your buying a car for only 5 years ownership then do whatever you want but if your buying for 15-20 yrs then service it like i mention above , you’ll never need an engine .

[@bobthrasher8226]

Wonder how it affects VVTi? They depend on oil pressure to do their thing so oil viscosity might affect timing. I think protection of bearings largely depends on oil pressure rather than viscosity. With sufficient oil pressure, the bearings just float on the oil.

[@doublebase6509]

Those are good questions. The VVTI is the same as the previous models (that used the 5W30), as far as I can tell, but I could be wrong. I will say I have noticed ZERO difference in performance/fuel economy/check engine lights/misfires. It’s all been normal. As far as protection, you might be right, but I went with the higher viscosity oil for a higher level of HTHS (high temp high shear) rating. Should have I been concerned with that in a daily driver? I’m not sure. The used oil analysis I posted was with the 0W20 - and that analysis came back phenomenal (and that was a 10,000 mile run). I’m four oil changes into this car now with a 5W30, and I’m 6,000 miles in on Amsoil Signature Series 5w30…I may send a sample out at the end of this interval. I’m not sure.

[@doublebase6509]

Thank you. You’re absolutely right; the demands that CAFE regulations has put on manufacturers (and oil) has completely driven all the changes in the industry. We’re now into ISLAC GF6A (GF6B), this change is because of the turbos, timing chains and direct injection/LSPI (low speed pre ignition)…and the never ending quest to reach corporate average fuel economy numbers. I’m not saying it’s all bad design and function, but there has been plenty of problems along the way. And I agree, Ultra Platinum and Mobil1 0W30 are excellent oils. I’m tempted to run Mobil1 0W40 FS (because it has a nice slug of PAO in it).

[@jimn.9990]

@@doublebase6509 From reading the Safety Data Sheet of the M1 0W-40 FS, I detect they are using anywhere from 42% to 60% hydrocracked petroleum oil, whereas the 100% Synthetic Amsoil SS oils contain only a mixture of base oils consisting of mostly PAO with some percentage degree of Ester (the exact mixture is a trade secret, to keep ahead of the competition). Rafe Briton, a former Lubrication Engineer of Mobil (who really puts forth highly educational KZbin Videos under the channel "Lubrication Explained," says any company that states on their label they are 100% Synthetic, then it follows they are ONLY using a combination of PAO & Ester. In addition I speculate that Amsoil uses a more expensive, higher-quality PAO (known as a mPAO) containing metallocene, which costs more, thereby delivering extra-desirable characteristics, since the SS line of oils have greater measurable statistics than other Amsoil lessor-grade 100% Synthetic Oils that are probably conventional PAOs (which Rafe calls cPAOs). By now you have guessed I am an independent Amsoil Dealer (all Amsoil Deralers are independent contractors, having no employment with Amsoil). The following true story occurred over a year ago that you could find interesting: I found an owner of a repair shop near my house using Mobil 1 0W-40 FS in both of his two Dodges with each containing the high-powered 6.4 liter (392 ci). He agreed to try the Amsoil 0W-40 Signature Series oil, after I explained to him all the wonderful benefits and attributes of Amsoil, together with my personal story as follows: I was a devoted Mobil 1 user until I bought Amsoil as an ordinary customer about 20 years ago, whereupon I was flabbergasted by the extra power of Amsoil (in comparison to all the various synthetic oils I have used over the years), so that solidified my sole allegiance to Amsoil from that point in time. About three weeks later, that mechanic/owner of a mechanical shop ordered 3 cases of oil, including the 0W-40 oil (for himself) and the Extended Life (mid grade) for his customers and he became one of my steady customers! I realize that you more than likely bought the Amsoil SS 5W-30 Oil from another Amsoil Dealer, so I therefore don't want to interfere with your business relationship with that Amsoil Dealer. However, anyone else interested in learning more from me (who is not working with an Amsoil Dealer), can send me an email to automotivebuff at my gmail address.

[@oficeptel6493]

Great information, thank you I have 2010 Highlander Base with 2GR-FE Version-2 (98K), as you said the oil cap says 5W-30 and I use that. However last winter I put in 0W-20 and I found that it cranks a lot easier in cold mornings (Northeast) but I start to hear my lifters ticking bit more. So I change it back to 5W-30 in a month or so. Looks like you have 2GR-FE Version-3. The Version-3 engines have different VVTi gears. VVTi gears works with oil pressure and oil viscosity could change oil pressure. I am not sure but maybe they compensate that with using 0W-20 oil. My understanding is heavier oil better for older engines as long as the oil goes though tiny holes in the hydraulic lifters. I do not have that much detail specs; do you see any spec or info about VVTi gears or hydraulic lifters? Also engineers usually good however, when it comes to the cost savings and sales pitches no one listens engineers 🙂

I can't talk about your engine. But I have the same opinion about the 1NZ-FXE. 😉 It's not an engineer's decision, it's a decision of the marketing department! They ask the engineers if it's possible. And they say that you *could* do it. So the marketing ppl tell you to do it. That's all. 🤪 As I'm living in the middle of the city I go for 0W-30, but that's my personal preference. Nobody can tell me that a HTHS of 2.9 to 3.5 or even above should "demage" the valvetrain in the long run while 2.6 to 2.8 does not. The engine runs more silently and if you add boron nitrate (ceramic) additive it runs even quieter. 🤭😉 There is something more: I see a difference if you drive just a few km/mi in the Winter in Siberia or if you drive full throttle for 1 h on a German Autobahn in summer. 😎 I had the 1NZ-FXE in a Prius mk 2 before, that ran on LPG. The oil was chrystal clear after 15,000 km and started to get a bit of color at 22,000 km. After 26,000 it hadn't even been black yet but middle to dark brown. I sold the Prius at 384,000 km due to rust. But the engine ran just fine. I'm having the same engine now in a Yaris Hybrid (XP13).

[@doublebase6509]

I get what you’re saying. And I don’t think there’s much difference between a 0W20 and 5W30 under normal operating conditions anyway. All oils tend to drop in viscosity a little bit and shed down through an interval…some very quickly. The oil will then thicken - or could thicken - if you go much too long on an interval. We are talking of course about the second number, the operating temperature number. The winter number of 0 in a 0W20 is obviously the viscosity at 0 degrees. There’s not much difference between the 0W and the 5W unless we are talking about -35 degrees bellow 0. I don’t operate in those temps, ever. Engine oil does not oxidize quicker in cold temps, it oxidizes quicker in hot temps. No worry with that part. Oil thickens in cold temps, which reduces flow, however oil is pumped in an engine…which is why these videos on KZbin showing cold oil racing down a track when poured cold are virtually useless. Oil is pumped and there isn’t a lot of difference between a 0W and a 5W at zero degrees. I probably should consider a 0W oil like a 0W30 or 0W40 just in canes I ever have to start my car in temps -35 or something close, but I was slightly concerned about the VII (viscosity index improvers because that’s a large spread).

Interesting, and this is what I mean when I tell people that your engine may suggest a different weight oil depending on what country you’re in, and what regulations the government may implement. In the US we have CAFE regulations (corporate average fuel economy), and because of those regulations manufacturers in this country go to extremes to meet fuel economy regulations. If they can’t they are fined. For a company like Toyota, who sells lots of cars, them not achieving CAFE would mean heavy fines. So, they and others will put lighter weight oils into engines that where heavier weights may be suggested elsewhere. Mexico is also a hotter climate, and climate plays a role too. But this engine (2GRFE) used to be spec’d for 5W30 regardless, and the change to 0W20 I believe e was made exclusively because of CAFE regulations.

Exactly they are trying to let a Fed Gov employee sitting behind a desk decide which oil we use. I bought a new Toyota with a 4 cylinder and I am in Florida. First oil change(1500m) I went without hesitation to 0w-30. No way I would run anything in Florida on 20 weight oil. That motor oil geek on KZbin probably works for the Feds. My next car will be a Mazda because I do not wants a turbo, CVT or hybrid, all will fail early and cost a whole lot to fix. I am age 65 and have serviced my own cars for 50 years.

[@doublebase6509]

Agree 100%

[@machine7767]

Is there a way to look up piston ring part numbers? Curious if rings changed at all.

[@doublebase6509]

I haven’t done that but I bet a google search would definitely give you some answers.

[@littlet7556]

Where did you get all the engine tolerance information from?

[@GameArmorGameplay]

The 2005 Avalon had this engine too.

[@doublebase6509]

Now was that the 3.3 with the timing belt? Or were they using the 3.5 2GRFE back then?

[@GameArmorGameplay]

@@doublebase6509 2005 Avalon had the 2GRFE with timing chain. 2004 Avalon had the 3.0L and the Solara V6 had the 3.3L

You _WILL_ start to burn oil FASTER with a higher viscosity oil. The reason is NOT MILEAGE or bearing clearances. It is because of low tension piston rings. IF you live in a semi or tropical climate and want 'extra protection' use 0W-30 full synthetic.

[@doublebase6509]

Interesting, I haven’t experienced any oil usage since switching to 5W30 compared to the 0W20 in the 20,000 miles since I switched. Can you explain why low tension rings wouldn’t benefit from a higher viscosity oil? Does the oil hover around the lands and not flow through the oil control ring as quick, causing the oil to coke up? Does the lighter weight oil get behind the low tension rings in their groove and help the rings press against the cylinder wall a little more (adding tension)?

[@dieselscience]

I can't give you a semester in tribology in a YT comment thread but I can get you started. I'm an engineer IRL but I won't go into the weeds.... -The low tension rings don't rely on oil behind them but between them and the cylinder walls. Lower tension doesn't require higher viscosity that would otherwise prevent good ring seating to keep adequate film strength. The advantage is less bore friction and more mileage. -It's not the 'weight' of the oil but the _viscosity_ that matters most. That is it's ability to with ease. @@doublebase6509

Odd my ‘12 Lexus es350 calls for 5w30

[@doublebase6509]

Lexus/Toyota switched to the 0W20 officially in this engine in 2013. It could have been a mid year thing, not sure. But it’s a further testament to 5W30. IMO

[@Noypi54494]

For Toyotas that spec 0w-8 or 0w-16 would 5w-30 be OK?

[@doublebase6509]

I would NOT DO THAT. The new Toyota engines are just that, new. If something is calling for a 0W8 or 16, using a 30 weight is a big difference.

[@Noypi54494]

@doublebase6509 Thanks!

[@toobeer]

You should first ask if the internals were changed and when you find out the answer is no, then realize that Toyota had to meet fuel efficiency standards the Goment imposed. Stay with 5W-30 IMHO>

[@doublebase6509]

Definitely!

[@tonywhite425]

So we are questioning the engineers on what weight oil to run hmmmmm

[@doublebase6509]

If you want to ask a question and get an answer from the video it would be why has Toyota changed their viscosity recommendations in the same engine they previously recommended (and still do in other countries) 5W30?

[@yosefkugel]

My 2AZ-fe 4cy 07 Camry claims to take 5w20-0w20, I put 5w30 runs better

[@Phone-sh7jg]

I added a quart of 20w50 to my 5w20 Ep oil. The valvoline 20w50 has made my 2011 tucson gls purr. Not click click click. I wanted to add lucas oil stabilizer, but it has no add pack. I mean, this engine is smooth. it's crazy quiet. The engine allows for 5w30.

[@dustinnop]

Running 0w40 in mine

[@doublebase6509]

I’ve definitely considered doing that. How’s that gone for you? Any noticeable drop in fuel economy?

[@dustinnop]

@@doublebase6509 Runs and sounds great. mpg seems the same

Stick w/the thin oil but add 1/2 quart of the original Lucas, should thick'n it up just enough👌

[@chief1193]

I don’t see how, 15w40 is recommended in this engine in the service manual. 😂😂😂

[@doublebase6509]

What service manual would that be?

👍🇨🇦

[@tonywhite425]

130k is nothing for those engines

[@doublebase6509]

You’re not wrong. The problem with owning one of these things is that- and it’s a good problem to have - no one is impressed with high mileage on these units until you reach 300,000 plus. Even then it’s not all that impressive.

[@doublebase6509]

@@GrantBillingsly no honestly, I’m not telling anyone to do what I’m doing, but this engine is spec’d for 5w30 and higher in other countries. Here, in the us, it’s not because of CAFE regulations. I just went 12,000 miles on an oil change interval using 5W30, I’m awaiting lab results from my oil sample. I’ll do a video on it. I’m pretty sure the oil/engine will be good. But we’ll see.

I’ll edit the video for you Ox. 😂

[@Nick-n3n2r]

Opinion only from online research. If you live in a very hot climate area's like Arizona /Florida 5w30 is better in that type of hot climate for your vehicle protection, Cold/snow country climate =0w20 / 5w 20 = could be even slightly better for vehicle protection / safer engine startup.ghtly

[@doublebase6509]

Yeah a lot of people go with the lower viscosity in winter and bump it up in the summer. My climate and commute is pretty decent for a 5w30 in winter (garaged/highway). Not a lot of extreme cold starts, etc. But I agree
