ABSTRACT:
Improved fuel compositions with decreased tendency to form deposits in the carburetor and on "early fuel evaporation" heating elements, inlet valves and the like contain a normally liquid fuel (usually a hydrocarbon fuel), a carboxylic acid ester which is either (1) an ester of a polyol and a C.sub.5 -C.sub.15 monocarboxylic acid or (2) an alkanol ester of a substituted succinic acid, and an oil-soluble, ester-type, nitrogen-free dispersant derived from a polyhydric alcohol and characterized by the presence therein of a substantially saturated aliphatic hydrocarbon-based radical having at least about 30 carbon atoms.
