Until 2009 the yaris was using 5-20 for fuel economy now they are back up to 5-30 again because it doesnt make a difference in the 1.5.

I once tried 0W-20 full-syn 300V Motul in my old Honda Jazz 1.3 and that made a significant difference from 5W-30 fully-synthetic engine oil.
I'd get 12km/liter before and after swtiching I'd get 13.5-14km/liter but I could feel the engine was hotter everytime I popped the hood open when I got home.

Agree. But worth finding out. :)
I think 5W-30 is spot on for hot and humid weather and daily driving. I'd use something slightly thicker for track use, like 5w or 10w-40 plus an oil cooler for added oil capacity :)
