Those of you that regularly take your Boxers to tracks and beat up on them for 8 hours, do you change your oil after? I always do on my car and for $50 for liquid-moly for the Boxer, it's not that expensive of insurance. Thoughts? I'd love to see some data from oil tests following track days but let's be honest, this is ADVRider, everyone is going to have the right answer and no one is going to have science to back it up I'll have 500 miles on my oil when I go to a track day on the 16th in CT. Then I ride all day then drive 150 miles home. Should I dump the oil and change it? Do I need to also do the oil filter, too?
