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.
