We're using PENNZOIL Platinum 5w-20 in it for this stretch , haven't decided to continue it's use . So , call your TOYOTA service center for verification of T.S.B. in their computer system , number is EG018-06 .

I looked at the TSB on NapaFix, 5w-20 is listed for Toyota and Scion, 0w-20 is listed for the 2AZ-FE engine, not the Yaris 1NZ-FE engine...their *note* at the start of the article seems kind of confusing though:
