(a) at least one functional fluid base stock; and
(b) an additive package comprising at least one derivative of a mono-, di-, or poly-alkylated naphthalenesulfonic acid selected from the group consisting of:
(i) neutral metal salts of said mono-, di-, and poly-alkylated naphthalenesulfonic acids;
(ii) basic metal salts of said mono-, di-, and poly-alkylated naphthalenesulfonic acids;
