    The present invention relates to a luboil additive with dispersivity and antirusting property, which contains the following structural characteristics: the naphthenic acyl group is connected on N atom of polyenic polyamine group in polyisobutenyl succinimide molecule, and the mole ratio of naphthenic acyl group and N atom is 1 : 1.5-6. Said invented luboil additive is made up by using succinimide to react with naphthenic acid. The new functional group is introduced on the succinimide molecule, so the said additive possesses dispersivity, and at the same time, also possesses antirusting property, and further can meet the requirements for oil-soluble property.
