Actually... no. That TSB has been widely misinterpreted in this forum. Read it carefully, paying close attention to the *title* of the TSB, and particularly to the text in the *second red box*.

The TSB was OK'ing GF-4 rather than GF-3, and further stating that certain future engines would be OK with 5w20 and/or 0w20. So far as I know, no current Yaris engines are really supposed to be using Xw20 oils.
