A lot of good information in here, fellas.

With that being said, I'm still unsure what oil I should run, or if there is even a sure recommendation at this point. For what it's worth, I'm a catless stage 2 car running 93. I plan to possibly run ms109 here and there also (don't know if this even matters). So when I get my oil changed next week, should I switch from 5w30 to 5w40? Motul?

I just spoke with Alex from Mission Tuning and he did in fact suggest I run Motul 5-40 as that's what he runs on his M5. I guess I'm leaning toward that way...

Edit: I'm guessing that means Motul Sport, rather than just the Motul brand in general?
