Got the TOYOTA service department where the '08 YARIS sedan was purchased to e-mail the T.S.B. as confirmation and saved the T.S.B. ( copied from P.C. ) in case of warranty issues with the use of the 5w-20 , says 5w-30 on oil cap and in owners manual . Best to be safe than sorry .

If Toyota says we can use 20 weight oil, then that means 0W-20 and 5W-20. At operational temperature both these oils will protect the same. The only difference is that in very cold temperatures, the 0W will pump a bit easier, but not a lot easier then the 5W.
Same for 5W-30 and 0W-30....an engine that runs on one can run on the other.
