Ethanol is an alcohol fuel with very high octane. It burns cooler than gasoline, and protects engine components by fiercely resisting knock. The trade-off of ethanol is that gas mileage will decrease by up to 35%. Per-gallon savings at the pump offset the increased consumption. Modern Audi’s have no corrosion issues with Ethanol fuels.
