ABSTRACT OF THE DISCLOSURE A composition comprising: (A) a first component selected from the group consisting of: (i) an oil-soluble ethylene backbone polymer having a number average molecular weight in the range of about 500 to about 50,000; (ii) a hydrocarbyl-substituted phenol of the formula (R*)a-Ar-(OH)b wherein R* is a hydrocarbyl group selected from the group consisting of mono-olefins of from about 8 to about 30 carbon atoms and polymers of at least 30 carbon atoms, Ar is an aromatic moiety having 0 to 4 optional substituents selected from the group consisting of lower alkyl, lower alkoxyl, nitro, halo or combinations of two or more of said optional substituents, and a and b are each independently an integer of 1 up to 5 times the number of aromatic nuclei present in Ar with the proviso that the sum of a and b does not exceed the unsatisfied valences of Ar; (iii) mixtures of (i) and (ii); and (B) as a second component, the reaction product of (B)(I) a hydrocarbyl-substituted carboxylic acylating agent with (B)(II) one or more amines, one or more alcohols, or a mixture of one or more amines and/or one or more alcohols, the hydrocarbyl substituent of said agent (B)(I) being selected from the group consisting of (i') one or more mono-olefins of from about 8 to about 30 carbon atoms; (ii') mixtures of one or more mono-olefins of from about 8 to about 30 carbon atoms with one or more olefin polymers of at least 30 carbon atoms selected from the group con- sisting of polymers of mono-1-olefins of from 2 to 8 carbon atoms, or the chlorinated or brominated analogs of such polymers; and (iii') one or more olefin polymers of at least 30 carbon atoms selected from the group consisting of (a) polymers of mono-olefins of from about 8 to about 30 carbon atoms; (b) interpolymers of mono-1-olefins of from 2 to 8 carbon atoms with mono-olefins of from about 8 to about 30 carbon atoms; (c) one or more mixtures of homopolymers and/or interpolymers of mono-1-olefins of from 2 to 8 carbon atoms with homopolymers and/or interpolymers of mono-olefins of from about 8 to about 30 carbon atoms; and (d) chlorinated or brominated analogs of (a),(b),or(c).
