I top off the tanks of my two Pilots with 1/2 Race Gas (110 Octane Leaded) and 1/2 Premium (94 Sunoco or 93 Amoco Silver) waiting for the blends to change to winter blend (no ethanol if you can find it)with Amsoil 32:1. I fog the
Engine and pull the piston to TDC (Top Dead Center) and cycle it once a month pulling the pull rope to keep the crank lubricated and put some Amsoil in the spark plug hole. I pull the batteries and hit them with a charge every couple of weeks while stored indoors. In the spring I have drain the gas completely if I didn't run them at all during the winter or if I didn't put Stabil in with the gas. I'd rather run $30 of race/prem gas in my lawnmower/weedwacker then fry a pilot Engine.
