I don't use it because owner's manual and cap states 5w30, and Toyota TSB adds 5w20 as a suitable viscosity for the 1NZ-FE Yaris 1.5 ...no where does Toyota list 0w20 for the Yaris, but sites for Mobil 1, Amsoil, etc do list 0w20, so believe who you want. I wouldn't chance it unless you're in a cold climate. Some that have used it mention increased noise.

I know that too thick of a viscosity can have a detrimental effect on cars with VVT, don't know if the same holds true with an oil that's too thin.
