5w-20 motor oil : who's using it ? ... - Toyota Yaris Forums

here's a concern , on T.S.B. ( http://www.automotiveforums.com/vbul...d.php?t=604802 ) for WARRANTY it states " NOT APPLICABLE TO WARRANTY " , does this mean TOYOTA is not responsible for the use of these oils in their engines ? Makes me wonder if they've done enough research and we are the lab rats . Many TOYOTA owners are having an issue with TOYOTA for the TACOMA frame that's rotting out and breaking . Especially for those who own the 2001 and 2002s , so my trust in TOYOTA is not 100% . Last , since the switch from 5w-30 > 5w-20 there's more engine noise , it's most noticeable at high speeds on the interstate . Seems like it could be the timing chain ,

. I'm considering to dump this fill of 5w-20 and go back to 5w-30 . The oil is PENNZOIL Platinum which is highly regarded at www.bobistheoilguy.com for U.O.A.s . If curious , http://www.bobistheoilguy.com/forums...Board=3&page=1 , there are other good U.O.A.s for the PLATINUM 5w-20 on other pages , so I doubt it's the oil .
