ABSTRACT:
A method to prevent intake valve sticking, or to reduce or eliminate intake valve sticking when it has already occurred, in an internal combustion engine which comprises contacting the engine intake valves with a fuel composition comprising a major amount of hydrocarbons boiling in the gasoline range and an amount effective to prevent, reduce or eliminate intake valve sticking of a hydrocarbyl poly(oxyalkylene) aminocarbamate having at least one basic nitrogen atom and an average molecular weight of about 500 to about 10,000, and wherein the hydrocarbyl group has from 1 to about 30 carbon atoms.
