Toyota OEM 0W-20 synthetic for the 5.7L?

Check out this vid. this guy does some pretty thorough research. i was surprised pennzoil got that far its one of the cheapest oils out there!!

This has been covered many times. TGMO is Mobil Super Syn with a specific add pack spec'd by Toyota. It has never been claimed to be a special oil from Japan.

 

Well, in all these oil threads I have seen at least one claim that it was Mobil Super Syn, but who really knows? TGMO is labeled as synthetic oil. Anyway, if TGMO really is Mobil Super Syn with a specified additive package, isn't it then starting off as a second-tier ExxonMobil product (with an additive package)?

That part about special oil from Japan was sarcasm. It wouldn't make much sense to ship motor oil from Japan when the US has domestic refining capacity of equal or superior technology.

 

If you look at Virgin Oil Analysis it closely resembles Mobil Super Synthetic, which is the entry level synthetic for Mobil. However, the add package is different in Toyota GMO compared to Mobil Super Synthetic. Same base stock, little different add package.

As far as add package goes, it is very stout. It is highly regarded and many oil geeks run it in all makes and models. It will go 10k with relative ease and a quality oil.

 

Not at all. Mobil Super Syn is a full synthetic oil. It's solid. The add pack that Toyota specs for it contains an extremely health dose of Moly among other things. TGMO is an excellent oil. Use with confidence.

 

This. The moly content is much higher than other similar oils.

It isn't much more than Mobil 1 so I'm sticking with it.

 

Ok there seems to be some confusion. I will state what the owners manual says:

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.

Outside temperature: Good from -20F--- to 105F

You can use any oil you want but my opinion is that these engines have very tight tolerance's and I would stick with what is recommended.

 

The requirement for 0w20 is solely due to CAFE standards and the EPA. The same engine is in the Tundra in Mexico and Toyotas own maintenance information site says you can run 5w30 in Mexico. Also the same 5.7 is in the Land cruiser world wide which is also able to run 0w20, 5w20, 5w30 and even 20w50. I personally have 5w30 in mine and the engine is definitely quieter, in all reality this engine was probably designed initially for 5w30 and then tested to see if 0w20 would improve mileage to meet CAFE. When you're talking the difference in milage you're also talking about the difference overall with all Tundra sold that year. So if 0w20 gets .02 better mileage than 5w30 you wont notice it but it will make a difference with CAFE.

 

You are right. Like I said you can run whatever you want. For USA rigs it says 0W-20.

 

Since you are an oil nerd, I found this somewhere (I think on this site):

Toyota Synthetic Motor Oil is also very close with one MASSIVE difference. Molybdenum is astronomically higher then pretty much every brand out there. Measured in PPM(parts per million) almost are major oils are between <1 - 90 with most in the <20 category. One of the highest, Amsoil, is stated at 60ppm but tested at 153. What I'm getting at is most additives for all highly rated motor oils fall into a "normal" range including molybdenum. This is where Toyota stands out. Toyota Synthetic molybdenum is 787ppm. Not double or triple other leading brands but in general well over 10 times the amount. Other tests have also shown Toyota's moly amounts to be vastly different. Obviously Toyota is not some crap car maker and pretty much owns the reliability scores on all tests.

 

FWIW...My dealer told me Toyota oil is Mobil 1 full synthetic - just branded as Toyota oil.

 

There is, in fact, an oil change alarm on the Tundra. Look in your owners manual under "Do It Yourself Maintenance".

 

Yeah but you need to set it yourself, you can enter your maintenance into the stereo if you are so inclined but there is not an oil life monitor like there is on some vehicles. Honda for example tracks the amount of city, highway, and idling you do to determine the oil life and even that you need to still manually reset after changing the oil.

 

they’re close, but wrong

 

So what oil is the consensus to run in a 2020 Tundra?

Toyota 0w-20, because they order it from Exxon Mobil to their own blend spec and QC?

Or Mobile 1 is >, than Mobile Super Synthetic which is base oil for Toyota label?

Or Castrol 0w-30, because it's the best at everything?

 

All of the VOAs I've looked at for Toyota 0w20 have a moly content of about 100, give or take.

 

Here is also something interesting I've found, now it is 5w30 being tested, but the additive packages are roughly the same as far a 0w20 goes.

Well they are moving to SP rated motor oil.
So here we go again!

 

I know this is a dated thread, nonetheless wanted know how this oil debacle has turned up…
I have a 2012 tundra 5.7, after the two yr. Toyota service ended, began doing the oil change maintenance, started changing every 5000 miles, M1 OW-20 full-syn. Just hit 240,000 a couple weeks ago… never burns oil, no leaks, however the closer it gets to 5000 miles the fuel consumption increases, nearly 13-14 mpg on highway, typically around 16-18 mpg… which has been pretty much consistent after 100,000 miles…. Still just has powerful as the day I drove it off the lot…

 

Very good. You just turned this into a oil and mpg thread. Well done sir.

 

0W20 or 0W30, my MPG stays pretty consistent. I like less engine noise, so I Stick with the 0W30 year-round, going to stretch to 7500 mile OCI's.

 

I drive in what the manual would consider severe driving conditions. Lots of gravel roads and mud. I use kirkland ow-20 and a toyota filter every 5000 miles and drive the piss out of it.
