Your using auto oil? I've always been told to use motorcycle-specific lubes, as automotive oils contain a much greater quanity of "friction modifiers" (to improve C.A.F.E. regulations in cars/trucks), which will cause clutch slippage. Never have used auto oil before, but don't think I'm gonna try either.
