The oil-soluble azo compounds of this invention are useful as dispersants, corrosion inhibitors and anti-wear agents in lubricating oil and fuel compositions. The predominant oil-soluble azo reaction product may be represented by the following formulas: STR1 wherein R represents an oil-solubilizing, synthetic, polymeric organic radical containing at least 20 carbon atoms, Y is independently selected from the group consisting of --NR2 R3 and --SR4, R2, r3, and R4 are independently selected from hydrogen, alkyl, cycloalkyl, aryl, alkaryl and aralkyl, X is independently selected from oxygen, sulfur and =NR5, with the proviso that when X is =NR5, Y is --NR2 R3, R5 is selected from the group consisting of alkyl, cycloalkyl, aryl and alkaryl, Z represents a polyvalent organic radical having a valence of n and selected from hydrocarbon, oxahydrocarbon, azahydrocarbon and thiahydrocarbon radicals and their oxygenated and halogenated derivatives, E is a monovalent radical selected from alkyl, cycloalkyl, aralkyl, aryl, and alkaryl, and n is an integer from 2 to 5.
