I've got a question for you guys. I'm considering going to M1 and I would like to know if a consensus has been formed as to whether the new 0w30 M1 is better than the 5w30. I've seen all this talk of additive packages, vi improvers, etc and was wondering which one of these perform better (lower wear #'s in UOAs). I'm assuming that they would be interchangebale in most climates. I live in VA and it's never below 20f here in the winter. Thanks!
