DISPERSANT COMBINATION FOR IMPROVED TRANSMISSION FLUIDS

摘要

A lubricant composition of an oil, a dispersant viscosity modifier of a poly(meth)acrylate copolymer having a nitrogen-containing monomer in an amount to provide at least about 0.4 percent by weight nitrogen to the copolymer, and a succinimide dispersant prepared in the substantial absence of chlorine gives good performance as a transmission fluid.
