The engine damage isn't a fair trade for a little extra mpg.

5w-20 yes, 0w-20 no

Read the web sites of Mobil1, Pennzoil Platinum, and all the major brands that make 20 weight oil, and even read the labels on their bottles:

"0w-20 wieght oils can be used in any application that calls for 5W-20 weight".

At operational temperature, BOTH 0w-20 and 5w-20 provide the EXACT SAME viscosity. How come you don't understand this?

And where is the engine damage you write of when using 0w-20? MANY UOA's show there is no more wear then if 5w-20 were used.

It seems you have the habit of talking out your a$$. ;-)

Luser, what part of the Toyota TSB do you not understand? It states do NOT use 0w-20 in the 1.5L

And check these oil threads over the last day or two, I read today where a Yaris owner switched from 5w-30 to just 5w-20 and got back a UOA that had extra wear metals.

Don't know why you keep pretending that what applies to the XD 1.8L applies to your Yaris 1.5L when Toyota's TSB specifically forbids 0w-20 in the Yaris engine...yeah, southern Ca sees lots of really frigid mornings, better use that 0w-20 eventho' the TSB says not to.
