I usually change my oil every 3,000kms. I have now started using Kawi S4 full-synthetic. My question is...does racing/track-riding shorten the intervals for when I should be changing my oil? I've heard guys say that they change their oil after every race weekend and stuff like that...I'm not gonna go to that extreme, but I just put about 300kms of track mileage on my bike...so that was 300kms of redline (or more, oops) shifts. Should I take some extra precaution with the timing of my next oil-change?
