摘要： [Problems]
An object of the present invention is to provide a viscosity modifier for lubricating oils and an additive composition for lubricating oils, for obtaining a lubricating oil composition excellent in storage stability under low temperature conditions as well as in viscosity characteristics at a low temperature.
[Solution to Problems]
The viscosity modifier for lubricating oils according to the present invention contains a resin (α), wherein the resin (α) satisfies specific requirements, and contains a grafted olefin polymer [R1] which is composed of a main chain and a side chain(s) and which satisfies the following requirements (i) and (ii). (i) The main chain is composed of a copolymer of ethylene and at least one α-olefin selected from α-olefins having from 3 to 12 carbon atoms, and contains the structural units derived from ethylene within the range of from 74 to 86 mol%. (ii) The side chain(s) is/are composed of a copolymer of ethylene and at least one α-olefin selected from α-olefins having from 3 to 12 carbon atoms, and contain(s) the structural units derived from ethylene within the range of from 30 to 65 mol%.

摘要： The present invention is directed to a method for improving the fuel efficiency of large low and medium speed engine oil compositions by reducing the traction coefficient of the oil by formulating the oil using a blend consisting of one or more Group I base oils having a kinematic viscosity at 100°C of from 2 to less than 12 mm2/s in combination with a Group IV base oil having a kinematic viscosity of at least 38, the difference in kinematic viscosity between the Group I and Group IV oils in the blend being at least 30 mm2/s in combination with a detergent.

摘要： Disclosed are uses of lubricant compositions comprising copolymers of monomers (A) selected from C6-C10 alkyl methacrylate monomers, and monomers (B) selected from C10-C18 alkyl methacrylate monomers, and a base oil or comprising a copolymer obtained by combining at least monomers (A) selected from C6-C10 alkyl methacrylate monomers, and monomers (B) selected from C10-C18 alkyl methacrylate monomers in a mixture and co-polymerizing the monomers for increasing the spreading and/or the self-spreading of the lubricant on the cylinder liner surface after its delivery.
