Motor fuel that consists of a mixture of gasoline and alcohol, typically methyl alcohol or ethyl alcohol.
Alcohol blends up to 10 percent alcohol can operate in essentially the same type of internal combustion engine as gasoline, (high-speed racing cars burn pure alcohol). Each fuel, however, has its own advantages and disadvantages. Alcohol creates less air pollution than gasoline, but alcohol-powered vehicles get fewer miles per gallon.
In an effort to reduce crude oil consumption while simultaneously lowering pollution and improving engine performance, refiners have developed various blends of gasoline and alcohol. The original blend was marketed under the name of Gasohol. Gasohol consists of 90 percent gasoline and 10 percent ethanol (alcohol). Another blend, M-85, consists of 85 percent methanol (methyl alcohol) and 15 percent unleaded gasoline.
