ABSTRACT:
Liquid fuels having anti-corrosion properties for use in internal combustion engines comprising (i) a major fraction of a monohydroxy alkanol having from 1 to about 5 carbon atoms, and (ii) a corrosion inhibiting amount of a mixture of (a) from about 5 to 95 parts of an alkyl or alkenyl succinic acid and an ester formed from that acid, or from a related alkyl or alkenyl succinic acid, and a glycol of 2 to 4 carbon atoms wherein the alkyl or alkenyl groups in the acid and in the ester each contain about 8 to 30 carbon atoms, and (b) from about 95 to 5 parts of at least one polymerized unsaturated aliphatic monocarboxylic acid having about 16 to 18 carbon atoms per molecule.
