Message So I've heard many positive comments with RP engine oil. Went to pick up some Racing 41(10W40) from Vinny and changed it a while ago. Cranked up the engine, noise was noticeably lower. Out for a spin, engine felt smoother than MOBIL 1, thus couldn't resist for a few shots of boost :-)

Now, at a double cost than MOBIL 1, RP better increases MPG as I heard. No experience with Amsoil, so no comparing stats. Will post an update about a week later on MPG.

BTW, MOBIL 1 10W30 only lasted about 2200 miles before I noticed engine noise increased and rough running. I did too many redlines, races and boost, etc.
