A lubricating oil composition comprising 0.001% to 10%, based on the total lubricating composition, of a compound of formula I: <IMAGE> wherein x is an integer from 1 to 25; R, R1 and R'' are the same or different and each is hydrogen, an optionally substituted straight- or branched-chain alkyl residue having from 1 to 20 carbon atoms, an alkenyl or alkynyl residue having from 2 to 12 carbon atoms, an optionally substituted cycloalkyl residue having from 3 to 12 carbon atoms, an optionally substituted aryl residue having from 6 to 10 carbon atoms, an optionally substituted aralkenyl or aralkynyl residue each having from 8 to 12 carbon atoms, an optionally substituted aralkyl residue having from 7 to 20 carbon atoms or an optionally substituted heterocyclic residue having from 3 to 10 ring members, an alkylene residue having from 2 to 12 carbon atoms, a cycloalkylene residue having from 5 to 12 carbon atoms or an arylene residue having from 6 to 10 carbon atoms; or R is the group -(S)xR'' and when R and R' are different from R'', R'' can also be one of the following residues: (a) a residue of formula: <IMAGE> II wherein Z is the atom grouping necessary to complete, with the carbon atom, a heterocyclic ring, or (b) a quaternary ammonium cation derived from the reaction of a compound of formula I, wherein R'' is hydrogen, with ammonia or an amine; and when R'' is hydrogen, R or R' can also be an organic residue which links two triazole residues of formula I, wherein R' is in the 4-position.
