Abstract
It has been found that a composition comprising an alkoxy alcohol, an aliphatic alcohol, a liquid petroleum distillate, a liquid fatty acid, a volatile nitrogen base, polyisobutenyl aminoethylethanolamine, and water may be used as an engine deposit cleaner which removes air and fuel induction system deposits, valve deposits, and combustion chamber deposits. The inventive composition may be introduced into the engine in lieu of fuel, or in conjunction with fuel while the engine is operating.
