Well I will be switching to PP 5W-30 about the end of october before it starts getting really cold out. It has a great add pack, but I like my moly. I saw a VOA of this stuff and it seems to have a ton of moly and alot of boron. Is this good stuff? I have a 4-quart oil sump. Would it be a good add for my oil? And how much should I add to my oil at the next OCI?
