I have been using Marvel Mystery oil for nearly a year since rebuilding my motor. I have read that a synthetic 2 stroke oil is good too. Which one is better? I know the MMO does not burn off as clean as say Protek-R. The guys that built my motor said that MMO is very good stuff...however it puts off more smoke than a Protek-R would. What do you think?? Should I switch to a synthetic as a pre-mix or stick my my Mystery Shiznit ??

 

Go read the email list, there is a raging debate going on right now about this very topic.
