A composition is disclosed which comprises: (A) at least one neutral or basic metal salt or boron-containing neutral or basic metal salt of at least one acidic organic compound, the metal in said salt being selected from the group consisting of alkali metals, alkaline-earth metals, zinc, copper, aluminum or a mixture of two or more of said metals; (B) at least one metal deactivator; and (C) at least one compound selected from the group consisting of (C-1) phosphorus-containing amide; (C-2) phosphorus-containing ester; (C-3) sulfur-coupled dithiocarbamate; (C-4) sulfur-containing compound represented by the formula (I), wherein R<1>, R<2>, R<3> and R<4> are each independently H or hydrocarbyl groups, R<1> and/or R<3> may be G<1> or G<2>; R<1> and R<2> and/or R<3> and R<4> together may be alkylene groups containing about 4 to about 7 carbon atoms; G<1> and G<2> are each independently C(X)R, COOR, C=N, R<5>-C=NR<6>, CON(R)2 or NO2, and G<1> also may be CH2OH, wherein X is O or S, each of R and R<5> are independently H or a hydrocarbyl group, R<6> is H or a hydrocarbyl group; when both G<1> and G<2> are R<5>C=NR<6>, the two R<6> groups together may be a hydrocarbylene group linking the two nitrogen atoms; when G<1> is CH2OH and G<2> is COOR, a lactone may be formed by intramolecular condensation of G<1> and G<2>; and x is an integer from 1 to about 8; and (C-5) mixture of two or more of any of (C-1) to (C-4). These compositions are useful as additives for lubricants and functional fluids, particularly hydraulic fluids, gear oils, greases and the like. |
