Was getting some drain plug gaskets at Toyota dealership today for the Pontiac Vibe and it's rear diff, transfer case, and transmission. Was doing drain&fills on all of it. And while I was there - I had a little chat with the parts guy. According to him - TGMO 0w20 is basically Mobil Super Synthetic 0w20. Not Mobil 1 0w20, like I heard before. How accurate is his statement? Anyone has any proof of either? I tried searching, but all search results lead to TGMO vs Mobil 1, not Mobil Super Synthetic... Maybe I just suck at searching. So what do y'all think? I was gonna use it in my dad's Tacoma. He doesn't want SRT 0w40 from my stash in his engine.
