摘要： The present invention provides a lubricating oil composition which has a viscosity much lower than that of a conventional lubricating oil composition, and which is excellent in metal fatigue life, wear resistance and electrical insulating properties. The lubricating oil composition according to the present invention comprises: (A) a lubricating base oil; and (B) from 0.6 to 4.0% by weight, based on the total weight of the lubricating oil composition, of a polydiene having a number average molecular weight of from 500 to 3,000 and containing a functional group on at least one end thereof. The above described lubricating oil composition does not comprise a viscosity index improver, and has a kinematic viscosity at 100°C of not less than 1 and less than 5 mm 2 /s.

摘要： A lubricant composition comprises (A) a major amount of an oil of lubricating viscosity and (B) a minor amount of a diblock copolymer comprising a poly(monovinyl aromatic hydrocarbon) block and a hydrogenated poly(conjugated diene) block where the diblock copolymer has a weight average molecular weight of 10,000 to 50,000 and a poly(monovinyl aromatic hydrocarbon) content of 5 to 45% by weight. A concentrate composition, a method for improving viscosity performance of a lubricant composition for an internal combustion engine, and a method for lubricating an internal combustion engine comprise the diblock copolymer which is especially useful for reducing soot­induced viscosity increase in a compression-ignited internal combustion engine equipped with an exhaust gas recirculation system.
