My feeling is that msot oils behave this way. If there are any you think don't let me know. I'd be interested to know.
Could it be becuase you're bike is a high reving bike (15,000 rpm) as opposed to my speed triple which is 10,000 rpm max?
So it degrades after 2500km instead of 5000km becuase of the higher reving bike??????
