Abstract
Corrosion caused by gasohol or alcohol motor fuels is inhibited by the addition of a corrosion inhibiting amount of the combination of (A) a polymer of a C.sub.18 polyunsaturated aliphatic monocarboxylic acid (e.g. linoleic dimer and/or trimer) and (B) the reaction product of (i) a polyalkylene polyamine, (ii) a C.sub.18 monounsaturated aliphatic monocarboxylic acid (e.g. oleic acid), and (iii) an alkenyl succinic anhydride, in which the alkenyl group contains 8 to 30 carbon atoms.
