 What octane gas? What octane gas should I be running with my stock motor? I see some people running 93 octane... I've been running regular unleaded in mine the whole time. Will changing the octane give me more performance?

Re: What octane gas? On stock motors some have backfire issues (mine did) 93 squared it away and I just run it that way.

Re: What octane gas? Only buy Chevron 93 octane from one of two trusted
stations - always burn any left over fuel in the truck
that is over two weeks old.... In all my boats, not just
the MM....
No performance gain - just a reliability gain...
