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.
