You might have to click "refresh" if it doesn't show up the first time.

Why they didn't state 0W20 is okay for the 1NZFE in that TSB is beyond me, probably so arguments like this could be started on the Internet...

20wt is 20wt, it's going to be from 5.60-9.29 cSt, regardless if the first number is 0W or 5W.

I don't even know why I bothered posting, watching you two fight over oil viscosity is much more entertaining...

If I lived in Japan, that's what I'd use. In the US we're given 2 choices by Toyota: 5w-20 and 5w-30
What the Toyota TSB and the owner's manual says is an approved viscosity for the US is what matters, but certain people just know better than Toyota when it comes to what'll work best.

And I guess 0w-20 and 5w-20 isn't the same, or the Toyota TSB would allow both for our 1NZ-FE, but they don't...and funny that Amsoil's 5w-20 is API certified, but their 0w-20 isn't.
