A composition is disclosed which comprises: (A) at least one neutral or basic metal salt or boroncontaining 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-contain-ing amide; (C-2) phosphorus-containing ester; (C-3) sulfur-coupled dithiocarbamate; (C-4) sulfur-containing compound represented by the formula <IMG> (I) wherein in Formula I: R1, R2, R3 and R4 are each independently H or hydrocarbyl groups; R1 and/or R3 may be G1 or G2; R1 and R2 and/or R3 and R4 together may be alkylene groups containing about 4 to about 7 carbon atoms; G1 and G2 are each independently C(X)R, COOR, C?N, R5-C=NR6, CON(R)2 or NO2, and G1 also may be CH2OH, wherein X is O or S, each of R and R5 are independently H or a hydrocarbyl group, R6 is H or a hydrocarbyl group; when both G1 and G2 are R5C=NR6, the two R6 groups together may be a hydrocarbylene group linking the two nitrogen atoms; when G1 is CH2OH and G2 is COOR, a lactone may be formed by intramolecular condensation of G1 and G2; 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.
