Abstract
A gasoline composition comprising (a) gasoline, (b) a deposit inhibitor or a detergent containing a basic nitrogen atom, (c) a carrier oil, and (d) one or more compounds selected from the group consisting of an ester of a fatty acid and an alkylene oxide addition compound to bisphenol, a compound obtained by the ester exchange reaction of an alcohol and a triglyceride-type fat or oil, an aliphatic or aromatic carboxylic acid, a metal salt of an aliphatic or aromatic carboxylic acid, an ester of an aliphatic or aromatic carboxylic acid and an alcohol, and an ester of boric acid. The composition has superior heat resistance and is excellent in removing deposits in the fuel intake systems and in keeping the systems clean.

A gasoline composition comprising,
- (a) gasoline,
- (b) 1-10,000 ppm of a deposit inhibitor or a detergent containing a basic nitrogen atom,
- (c) 1-10,000 ppm of a carrier oil, and
- (d) 1-5,000 ppm of an ester of a fatty acid and an alkylene oxide addition compound, wherein the compound to which the alkylene oxide is added has the following formula (1), ##STR13## wherein X represents ##STR14## wherein Z.sup.1 and Z.sup.2 are individually a hydrogen atom, a trifluoromethyl group, or a substituted or unsubstituted alkyl or alkenyl group having 1-6 carbon atoms, or a phenyl group, and Y.sup.1 and Y.sup.2 are individually a hydrogen atom or a substituted or unsubstituted alkyl or alkenyl group having 1-6 carbon atoms, or a phenyl group.
