Abstract:
A lubricant composition of (a) an oil of lubricating viscosity; (b) a poly(meth)acrylate ester polymer comprising 0.5 to 5 weight percent of amine nitrogen-containing dispersant monomer units and (c) an esterified copolymer with a backbone comprising units derived from (i) an α-olefin monomer of at least about 6 carbon atoms, (ii) an ethylenically unsaturated carboxylic acid or derivative thereof, further containing nitrogen functionality in groups pendant from the copolymer backbone, provides a good combination of seal performance and oxidation resistance.

Claim (Index 16):
The lubricant composition of  claim 1  wherein the weight average molecular weight of the esterified copolymer (c) is about 5,000 to about 35,000 or about 5,000 to about 21,000 or about 8,000 to about 20,000 or about 12,000 to about 18,000.
