Ethanol, a naturally oxygenated fuel, is crafted through the fermentation of organic materials like corn, grains, and various crop and forestry waste. Typically blended with gasoline, it comes in varying levels such as E10 and E85.
E10, a premium high-octane gasoline, can be utilized in any gasoline vehicle without necessitating modifications. On the other hand, E85, comprising 85% ethanol and 15% gasoline, boasts a higher octane rating and is designated for specific vehicles. Major domestic automakers offer FlexFuel Vehicles (FFVs), compatible with E85, at prices comparable to gasoline counterparts.
According to the National Ethanol Vehicle Association, around six million E85 vehicles were in operation on U.S. roads by the close of the 2006 model year. Applications for E85 span a range of vehicles including non-diesel fleet vehicles, buses, light-duty vehicles, and delivery trucks.
