Several
common ethanol fuel mixtures are in use around the world. The use of pure hydrous or anhydrous ethanol in
internal combustion engines (ICEs) is only possible if the engines are designed or modified for that purpose, and used only in
automobiles,
light-duty trucks and
motorcycles. Anhydrous ethanol can be blended with
gasoline (petrol) for use in gasoline engines, but with high ethanol content only after minor engine modifications.
