Cars not designed or modified for E85 or flex fuel use cannot be
operated on more than about 10% ethanol or methanol in gasoline.
Since gasoline has a higher heat value per gallon and per pound than
ethanol or methanol mileage will be better on gasoline than on
alcohols.
However, alcohols can increase engine power and act as a powerful
cleaning agent in engines set up for it. It also burns cooler.
