Silky,

With all due respect if Dr AE Haas can run 20 wts in an Enzo and a Lamborghini I think a stock Yaris will do fine on it if it's a quality oil formulation. I bet the Enzo and Lambo don't mention 0W-20 or 0W-30 in there manuals either. :)
I thought you were initially pleased with the Syntec? I believe you had "padded" it with some 10W-40, correct? The noise you keep referring to-when is it occuring? My Yaris is a little noisy when "cold" but is very quiet when fully warmed up and the oil is at it's "thinnest". I have always used 20 wt so far and have heard rumors the factory fill was a 20 also (I have no proof for this yet). Engine loves to rev but rarely gets to as I putt around and gawk at my ecometer!

The Rotella is a nice oil but would make me uneasy during a NH winter! Sure, I think it will start fine but it may (rather loudly) protest. Hope it works out for you better than the Syntec-let us know!
