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 select- ed 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 Image (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 independ- ently 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 hydro- carbyl 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.
