Abstract

This invention relates to a composition comprising the combination of(A) at least one alkyl phenol of the formulawherein each R is independently a substantially saturated hydrocarbon-based group of an average of at least about 10 aliphatic carbon atoms; a, and b are each independently an integer of one up to three times the number of aromatic nuclei present in Ar with the proviso that the sum of a, b and c does not exceed the unsatisfied valences of Ar; and Ar is an aromatic moiety which is a single ring, a fused ring or a linked polynuclear ring having 0 to 3 optional substituents selected from the group consisting essentially of lower alkyl, lower alkoxyl, carboalkoxy methylol or lower hydrocarbon-based substituted methylol, nitro, nitroso, halo and combinations of said optional substituents, and(B) at least one amino compound with the proviso that the amino compound is not an amino phenol.Lubricants and lubricating oil-fuel mixtures for two-cycle engines which include the above compositions, and methods for lubricating two-cycle engines are also within the scope of this invention.
