+1 on running C12 since you can’t go wrong there. I ran “100” octane from a local 76 station pump which wrecked the piston and cylinder from detonation in only a few sessions. Turns out that fuel has a 95 motor octane. Recommended motor octane for these engines is at least 100 to prevent detonation.
