All that ethanol kills 2 cycle engines.
I just got another 15 gallons of ethanol-free 92 octane at my neighborhood feed store today.......
I run all my vehicles on E0. It is more expensive, but my chainsaw, my surviving lawnmower (of 3), my surviving other small engines thank me. My father gave up commercial fishing last year, (in his 80s), but part of the reason was an outboard failure a mile offshore because of E10. In their area of the tidewater he cannot get no ethanol gasoline, not even at the marinas, and the fuel systems in his outboard motors were getting wrecked on an annual basis.
