5w-20 Oil

And before you say it's okay because Amsoil says it's okay, when Toyota says not okay, remember that Amsoil does NOT offer an API approved 0w-20...you'd have to go the XL 5w-20 or XL 5w-30 to get an API approved oil to keep from voiding warranties.

You are very, very confused. The reason toyota does that has NOTHING to do with 0w and 5w. The reason is the differences in additive packages. For example, I would not put any 0w-20 in my Yaris, however I would put in AMSoil 0w-20 and Mobil1 0w-20, but not others.

It's about the additive packages, and not the viscosity. Now as time goes on, more 0w-20 brands will be good for the Yaris, but today not all.

Show me where Toyota says do NOT use 0w-20 because of additive packages, but use 5w-20 and 5w-30 for the Yaris (1NZ-FE) because their additive packages pown 0w-20's...all I see in Toyota's TSB is that they will allow 5w-20 but NOT 0w-20 in the Yaris motor, and there have never been little footnotes about *additive packages* as far as I can tell, plus you've ALWAYS stated that the TSB states 5w-20 is okay, so "with that being said 0w-20 is okay because it performs exactly like 5w-20" without ever mentioning certain additive packages in certain oil brands being the deciding factor.

And why would you use Amsoil 0w-20? It's not API approved...hmmmm...but the Amsoil XL 5w-20 is API approved ...bet that's another reason why the Toyota TSB says yes to 5w-20 and no to 0w-20. Bottom line: Until the TSB says yes to 0w-20 it's wrong to use it, but keep using it year round in southern California.

You must wake up in a new world every day. How many times have you claimed that brand doesn't matter, that the cheapest discount synthetic will make an engine last just as long as an expensive synthetic, like Royal Purple? I'm not the one that's confused; I use API certified oil, and the proper viscosity, you don't.

You want a link? Go to AMSoil's web site. Go to Mobil1's website. You can run BOTH 0w-20's in your Yaris with absolute confidence. So why theirs and not others 0w-20?

ADDITIVE PACKAGE.

For example, this is why SL grade 5w-30 can be run in car X but not car Y, yet BOTH cars call for 5w-30, but not ANY 5w-30.

So if two oils are 5w-30 yet only one can be run in car X, why?

ADDITIVE PACKAGE differences.

There are cars out there that call for a particular brand of 5w-30 or 5w-20 or 0w-20 because not any brand will do even if the viscosity range is perfect....why? Additive package differences, again.

Go to AMSoil's web site.

To find a non API approved listing? No.

Go to Mobil1's website.

To see them disagree with Toyota's TSB? No.

You can run BOTH 0w-20's in your Yaris with absolute confidence.

Wrong. Not listed as approved by Toyota, AMSOIL 0w-20 is not API certified.

So why theirs and not others 0w-20?

Why you but not Toyota?

ADDITIVE PACKAGE.

For example, this is why SL grade 5w-30 can be run in car X but not car Y, yet BOTH cars call for 5w-30, but not ANY 5w-30.

ANY car that calls for SL 5w-30 can run ANY brand of SL 5w-30.

So if two oils are 5w-30 yet only one can be run in car X, why?

If Toyota says 5w-20 for your Y than why do you run 0w-20 when their TSB says it's only for their X?

ADDITIVE PACKAGE differences.

There are cars out there that call for a particular brand of 5w-30 or 5w-20 or 0w-20 because not any brand will do even if the viscosity range is perfect....why? Additive package differences, again.

Right back to you saying that Toyota's TSB allows particular brands of 0w-20 because of those special non API approved additive packages...again...proof? Or just your need and not Toyota's need, again?

I've said it many times and I will say it again: BRAND DOES NOT MATTER.

However this thread is about 0w-20 vs. 5w-20. In regard to this particular and specific issue, brand does in fact matter because not all brands provide the appropriate additive packages required by certain cars.

Now if one wants to use oils found in their manuals/TSBs (5w-20, 5w-30) in their Yaris then as long as the oil is either made by AMSoil or is API-SM certified, then BRAND DOES NOT MATTER.

For example, when I run 5w30 or 5w-20 the brand of the synthetic does not matter. But for 0w-20 the only brands I will use are Mobile1 and AMSoil. This is the EXCEPTION, and not the rule.

Hope this clarifies.

It does

I've never seen you make viscosity distinctions until now, when I called you on it.

And they have to have the appropriate additive packages to even produce a 0w-20 viscosity, fyi.

And as in certain cars, our 1NZ-FE Yaris? Still haven't seen where Toyota lists 0w-20 for it yet.

And, again, stick to that lose/lose formula of:
1) Use an Amsoil grade that isn't API approved
2) Use a viscosity that isn't listed on Toyota's TSB
