Howdy, folks. Here's my situation: I'm going to autocross my car in the next month or so, and I was tossing around the idea of changing the oil. The car in question is a 2003 Honda S2000. The oil that's currently in there is Mobil 1 EP 10w30 w/ LC20 and about 6ozs of VSOT with around 4000 miles on it. The car's got 41000 miles on it, and is just fresh out of a Auto-Rx treatment. Whatcha think?
