Good to know it most likely is e free
also you can buy fuel from a marine place NOW and stabilize it for use through the winter, just dont fill the machine yet, its the fuel in the carb that causes problems not fuel sitting in your gas can. (at least in terms of the length of time we are starting).
I buy 5 gallons of fuel every novemberish just for the snow blower to make sure i dont run out mid storm.
