摘要 |
A lubricating composition, method of making, and method of use are disclosed. The lubricant includes an esterified copolymer including a backbone that includes units derived from a vinyl aliphatic monomer and units derived from a carboxylic acid monomer, the carboxylic acid monomer comprising an alpha,beta-ethylenically unsaturated dicarboxylic acid or derivative thereof. The lubricating composition also includes an oil of lubricating viscosity. The lubricating composition includes no more than 2.5 wt. % of dispersant for dispersing oxidation products, other than the esterified copolymer. |
