Hi guys, I picked up a new(er) integra with only 80km (50K) miles. Im switching it to synthetic from whatever mystery juice is in there, just because of the daily stop and go and occasional track time it sees. Should I shorten up my oil change interval after Ive switched? Or would it be better to run a flush? Or should I just say screw it and change it as usual and not look back? I've search, and the search engine keeps showing me the same results?? Thanks for any input. Ryan
