See attached official Toyota TSB, and you will see that the Yaris 1.5L engine can use 20 weight.

NO, you're drawing your own stupid conclusions again to alter their "5w-20" recommendation to fit into your straight 20 and 0w-20 needs for a southern Ca. climate condition that never needs 0w oil in the first place.

And yes, I've been using 0W-20 in my Yaris for the past 54,000 miles. Increase in MPG is just around 1% however. I use the light stuff so that it gets circulated quick during cold morning starts. Quick circulation means less wear and tear during the first start up. And it is during the first start up that 90% of engine wear happens. My engine does not consume any oil after 5,000 miles. The engine runs smooth and no strange sounds coming out of it either.

You don't need to worry about cold morning startups, you live in so. Ca. ...and film strength always plays a part in not wearing and tearing your internals. Not saying you'll blow your motor or make it drink oil, just saying that you're asking for trouble for using a viscosity that is NOT listed for the Yaris in the Toyota TSB...did you do a XD engine swap? Yes? Then that'd be okay...Yaris 1.5 still, not okay, according to the Toyota TSB that you like so much but can't comprehend.
