I work at Costco and they have the cheapest gas anywhere you want to look. There gas states up to 10% ethanol in the fuel.With any gas that says that is it best to always use the ethanol chip in your sled. Has anybody ran that type of premium fuel and ran it with the standard fuel module? I would like to buy my sled gas at Costco, but I don't want any problems with my 011 Pro.
