Don't use it. Burned out a piston in my Summit 800 and local dealer says cause was leaving ethanol fuel in tank even though fuel stabilizer was present. Says E10 is only good for 30 days then will clog carb, idle jets first with result oil injector doesn't work properly. I believe him, cost me plenty to fix. You can still buy non ethanol fuel if you look around and now the Feds want to increase it to 15% which is even worse. My advice-don't use ethanol fuel in any 2 cycle engine.
