The present invention is a mono- or di-acid generating moieties (preferably a dicarboxylic acid or anhydride moieties) of about 20,000 to about 500,000 can be at least one terminally unsaturated ethylene alpha having a mean molecular weight of the substituted olefin polymer (here, the terminal unsaturated groups present invention relates to oil compositions useful additives include include a terminal ethenyl unsaturation alkylpiperidinyl). Mono of the present invention and a dicarboxylic acid or anhydride substituted polymers are useful as additives for oil-based compositions, such as lubricants per se, and a nucleophilic reagent (e.g., amines, alcohols, amino alcohols, and reactive metal compounds) and in response to, for example, it can form a useful oil composition additives, the product improvements zero multifunctional viscosity index.
