    Abstract: This invention relates to a composition comprising (A) a major amount of an oil of lubricating viscosity and (B) a minor amount of (i) a reaction product of (a) at least one dimercaptothiadiazole, and (b) at least one alpha, beta-unsaturated ester prepared by reacting an alpha, beta-unsaturated carboxylic acylating agent with a hydroxy compound, or (ii) a salt of the reaction product, provided that when the acylating agent is a monocarboxylic acylating agent then the hydroxy compound is a monohydroxy compound, and provided that when the ester is formed from a maleic acylating agent, then the ester is formed from a sulfur-containing hydroxy compound or a combination of a polyhydroxy compound and a monohydroxy. The invention also relates to aqueous fluids, greases, and concentrate compositions containing the reaction products and its salts. These additives generally show an ability to improve antiwear (including extreme pressure) and antioxidation properties of lubricants, aqueous fluids, and greases.
