Viscosity index improver, engine lubricant composition, and concentrate |
| abstract |
Disclosed are a viscosity index improver which comprises a copolymer (A) consisting essentially of an alkyl methacrylate (a1), and one or more monomers (a2) selected from the group of conjugated dienes, acetylene, substituted acetylene, alkyl vinyl ethers and alkyl allyl ethers; an engine lubricant composition comprising said viscosity index improver and base oil; and a concentrate comprising an increased amount of said viscosity index improver and base oil. The viscosity index improver gives reduced amounts of coked products, while improving the fuel-related performance characteristics of cars that use the engine lubricant composition comprising the improver. |
