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 one or more C16 to C18 polyunsaturated aliphatic monocarboxylic acid (e.g., linoleic dimer and/or trimer) and (B) a polyisobutenyl succinimide of an alkylenepolyamine. |
