Ethanol (CH3CH2OH) is also referred to as ethyl alcohol or grain alcohol. It is a clear, colorless liquid made up of chemical compounds whose molecules contain a hydroxyl group, -OH, bonded to a carbon atom. Fuel-grade ethanol is blended with a percentage of gasoline to form motor oil.
The Clean Air Act Amendments of 1990 mandated the sale of oxygenated fuels in areas with unhealthy levels of carbon monoxide. This led to a strong demand for ethanol as an oxygenated blend with gasoline.
About 2 billion gallons are added to gasoline to increase octane and improve the emission quality of gasoline in the United States each year.
