Abstract
This invention relates to a composition, comprising: (A) a compound represented by the formula ##STR1## wherein in Formula (A-I), G.sup.1 and G.sup.2 are independently R, OR, SR or NRR wherein each R is independently a hydrocarbyl group, X.sup.1 and X.sup.2 are independently O or S, and n is zero to 3; and (B) an acylated nitrogen-containing compound having a substituent of at least 10 aliphatic carbon atoms. In one embodiment, the inventive composition further comprises (C) a phosphorus compound. In one embodiment, the inventive composition further comprises (D) an alkali or alkaline earth metal salt of an organic sulfur acid, carboxylic acid or phenol. In one embodiment, the inventive composition further comprises (E) a thiocarbamate. These compositions are useful in providing lubricating compositions and functional fluids with enhanced antiwear properties.
