OP surely understands that the 2.7L 4 cylinder engine found in his 1995 Tacoma is the 3RZ FE engine, which does not have oil pressure-controlled variable valve timing.

My 2005 2TR FE and my 2018 2TR FE have been significantly affected in terms of performance and fuel economy by variances in viscosity grade.

Both M1 0W40 and Motul Specific 508.00 509.00 0W20 would likely avoid piston ring coking and excessive valve stem seal wear.

Gokhan notably used M1 0W40 right after replacing the valve stem seals on his Corolla, then switching to TGMO 0W20, and now M1 EP 0W20.

Anybody care to chime in about oil condition? Getting pretty tired of “warranty theory 101” around here.

How do the knowledgeable posters feel the lube performed?

I have two of these...ones a v6. no diff in fuel economy between the 40 and 20. No difference in sound either fwiw. Both spin over 3k in normal highway driving...both are dog slow

Wrong!
The last sentence in that Bulletin states the warranty will not be covered. They are recommending we do not void their warranty.

Well, if we are going to lawyer this to death, it could be said that the document does not say what country the oil specification must be from to maintain warranty, so if the oil used could be found in specification anywhere in the world it would be ok to use....which also backs up the owner's manual which does state a thicker oil may be required for protection.


I use the overseas manual to choose my viscosity.

It says if engine damage occurs because of the oil then it will not be covered under warranty. Obviously engine damage is not occurring per the posted UOA (and would not due to an oil such as Mobil 1 0W-40). And, this is a Toyota under consideration not a Hyundai.

if you have a plausible and technical scenario where using Mobil 1 0W-40 will result in damage his engine then let's hear it. That's one of the best oils on the planet.

TBN looks good. Hoping some of the numbers are high due to break in. TBN looks money and it looks like the m1 held up great. You guys think i have a winner here?


Thank you for the report.

I will offer a counterpoint FWIW.

I have driven two different 2TR FE's for a grand total of 870k miles.
Local deliveries of small parcels, light pallets and such has been on the front burner for me. Like you, I put a lot of freeway miles on my Taco.

TBN does not concern me as much as you, with all the freeway miles. TBN is not linear. My personal preference is a carefully selected lower viscosity oil.

Watch for the proverbial piston ring coking and valve stem seal wear as you approach 200k miles, with the accompanying oil consumption.

Enjoy your sled, Sir !



He'll likely avoid those issues using 0W40.



Yepp, agree, i can bet my 2 cents on that.

Bottom line, it’s foolish to put your warranty at risk because you think you know more than the engineers who designed the vehicle.


That's how I feel. I'm one of those people who follow the manufacturers recommendations "to the letter" while the vehicle is under warranty. Why take the risk of giving the service department (and/or the manufacturer) an easy way to refuse service if / when you ever have a problem by using a product other than what is specifically called for?

I see forums just littered with people bitterly complaining that the dealer won't work on their vehicle after they've altered / changed the vehicle, used different fluids than what were explicitly called for in the owner's manual, etc., etc.

Here’s directly from Toyota manual. Pay specific attention to the last sentence.

Quote

Engine oil selection
“Toyota Genuine Motor Oil” is used in your Toyota vehicle. Use Toyota approved “Toyota Genuine Motor Oil” or equivalent to satisfy the following grade and viscosity.

Oil grade: ILSAC GF-5 multigrade engine oil

Recommended viscosity: SAE 0W-20

SAE 0W-20 is the best choice for good fuel economy and good starting in cold weather.
If SAE 0W-20 is not available, SAE 5W-20 oil may be used. However, it must be replaced with SAE 0W-20 at the next oil change.

Oil viscosity (0W-20 is explained here as an example):

• The 0W in 0W-20 indicates the characteristic of the oil which allows cold
startability. Oils with a lower value before the W allow for easier starting
of the engine in cold weather.

• The 20 in 0W-20 indicates the viscosity characteristic of the oil when the
oil is at high temperature. An oil with a higher viscosity (one with a higher value) may be better suited if the vehicle is operated at high speeds, or under extreme load conditions.

Good stuff. I ran M1 0w40 once in my Prius - engine ran like a top... just effected my MPG more than I'd like (more due to the way the Prius engine works, probably negligible difference in your application). Congrats on the truck btw... love a good Tacoma.

I think you have a winner with the 0w-40! I would continue to use it. You have evidence to back up its performance.
