A film-forming corrosion inhibitor suitable for use in 2-cycle engine oils is prepared from the reaction product of 1 mole of dodecenylsuccinic anhydride with 0.6-0.95 moles propylene glycol. The anhydride-glycol adduct is prepared in a relatively short reaction time, and the engine oil containing the corrosion inhibitor is compatible with other oil and fuel additive components, while industry standard performance properties are maintained.
