But thanks for the backpedal, because on this very thread I asked if 0w-20 was okay according to Toyota's TSB and you jumped on the thread with your little TSB link pretending that it was some sort of proof that Toyota thinks 0W-20 is okay for the Yaris.


Quote:

"ALL the oil brands that sell 0w-20 make the claim that that their oil is a great match for ANY 5w-20 application. AMSoil, Mobil1 and others make this claim.

And you are dead wrong about California and 0w weight oil. Anytime the ambient temperature is below 40F one will IN FACt benefit from 0w oil. You are also very foolish to think that it does not snow in California. It does in fact.

Film strength and viscosity have NOTHING to do with each other. And in fact, there are some 20 weights that provide film longer then heavier oils.

What you fail to understand is that 0w-20 and 5w-20 provide the SAME protection at full operational temperatures. The difference is during the first morning start of the cold day. And if a 5w is fine, then a 0w will be too. This is true according to AMSoil, and Mobil1 and ALL other makes that make 0W oils.

According to Toyota, 5w-20 can be used safely in a Yaris 1.5L engine. Now, that being true, one can ALSO use 0w-20, 0w-30 too for our Yaris engines, and this according to ALL the makers of 0w oils.

It is too bad you behave like you know more about oil then Toyota, AMSoil, and Mobil1."

You are wrong again! I didn't backpedel because there is no need to.

Toyota's 800 customer service line says you CAN run M1 or AMSoil 0W-20 as these do meet all their criteria for Yarii engines. The TSB published came out AFTER they drew this conclusion. Call Mobil1 and AMSoil and see if you know more about oil then they. You don't.

And I certainly would never run an oil that would damage my engine for grins or giggles.

Really?

Toyota says to use "AMSOIL" even when it's NOT API approved?

AMSOIL's XL series is API approved, but it doesn't come in 0w-20

as these do meet all their criteria for Yarii engines.

They require API approval and AMSOIL's 0w-20 isn't API approved.

The TSB published came out AFTER they drew this conclusion.

OH, I see...the TSB came out AFTER, and not before And the TSB says do NOT use 0w-20 in the Yaris, gotcha! :)

Call Mobil1 and AMSoil and see if you know more about oil then they. You don't.

They don't know enough or they wouldn't go against what Toyota wants to see in their Yaris crankcases.

And I certainly would never run an oil that would damage my engine for grins or giggles.

Of course you would to get that extra mpg...in a southern California climate that doesn't need better than 5w, any better than what Toyota recommends, especially if you're running synthetic.
