A phosphorous- and sulfur-containing additive and its use to impart anti-wear properties to oleaginous compositions such as fuels and lubricating oils, particularly power transmission compositions, such as automatic transmission fluids, is disclosed. The additive comprises a mixture of products formed, for example, by simultaneously reacting (1) a beta-hydroxy thioether, such as thiobisethanol, (2) a phosphorous- containing reactant, such as triethyl phosphite and (3) optionally, a nucleophilic reactant capable of reacting with the episulfonium cation Image to form thioether species.
