Answer 1

Cars in the mid 80s and older dont run off of Ethanol that they put into gas now a days try getting gas at somewhere that dosent add ethanol to the gas or even try finding a place that has no ethanol in the gas. Ethanol damages fuel systems in older cars, they cant take it its to thin. Ethanol burns faster to and it dosnt produce as much power as regular gasoline.
