What Oil do you guys recomend/Use ?

You're confused, but that's okay. I do follow my rules. The TSB shows 20 weight for our engines, and I use 20 weight, and the UOA's show less wear then if I used 30 weight. Sure, the filler cap shows 30 weight, BUT the TSB which came out later says otherwise. I'm sticking with the TSB. As to 0W weight, I use that because at full operational temperature 0w-20 and 5w-20 protect exactly the same; hence the 20 part of those grades. The 0w on cold mornings flows to the upper parts of thje engine faster and gets to more parts of the internals faster.

It's okay that you're too dense to read...the TSB *notes* the 0w-20 is for the 2AZ-FE engine, not the Yaris 1NZ-FE engine...you did a XD motor swap in your Yaris?!

And if you live in CA why worry about those "cold mornings flows"...besides, in that TSB that you're swearing by, take note of the note @ the top of the page:

"The recommended viscosity grade for this oil differs according to vehicle model. Use the recommended grade specified on the oil filler cap or in the Repair Manual or Owner’s Manual for each vehicle."
