I was in a local Wally World and was of course at the oil asile and saw 1 gallon jugs (5 qts) of M1 0w-30. According to th einfo on the bottle, it exceeds Fords, Gms, Hondas, and Toyota specs and recommendations. Toyota recommends 5w-30 for my Venza. Would I or anyone else in a similiar situation have any problems if I ran the green cap M1 instead of the 5w-30????? I don't want to void my warranty but if the oil exceeds what they say put in; i'd think i'd be ok. What are ya'lls thoughts? Would just like the best MPG possible---VenzaTRD
