Same for 5W-30 and 0W-30....an engine that runs on one can run on the other.

Not exactly correct engine lubricant may not get to designated operational temp and viscosity of the 0W will be much less than the 5W at say 75 celcius. I am Chemist!
Make Love not Bombs! I see TSB b4 it states NO 020!

If you're a chemist then you should know better....the 20 in 0W-20 and 5W-20 provide the same protection at full operating temperature (around 212 degrees F).

It is the first number, the 0 in 0W-20 that is thinner at cold temperatures then 5W.

And Gid yes you are correct, the Yaris engine is not TSB'd for 0w, but rather for 5W-20. However I do use 0w because the UOA reports I've seen from other Yaris owners show the same wear metals as those that used 5W-20.

You are dangerouse person with a little knowledge to be bad, but not enough education to make interpolation. You may have to study some more - This Bob OIly Guy is no Koran!
