I was wondering what the recommended OCI would be for my 01 WR250F? I don't race, very rarely go to the track (taken it twice, and I ride the mini track). Usually pretty easy on the throttle and shift around 10-11K. I do fire roads riding and occasionally a trip to the desert in southern california.

Currently I'm running Mobil 1 Syn 10W40 or Castrol Synethic 10W40 (whatever's cheaper).

Thanks for the tips.
