I was talking to a buddy of mine and mentioned how the mileage on my 2010 Softail goes in the crapper when I have to put ethanol added fuel in instead of just the premium unleaded gas. He says that his ( I don't remember the year ) Sportster gets 3 to 4 miles to the gallon MORE using the ethanol stuff. Looked me in the eye and said that he checked it 4 different times. Anyone else see their mileage improve using the stuff?
