Abstract:
1. A lubricating oil composition comprising a first base oil and a second base oil; wherein the first base oil comprises at least one component selected from the group consisting of (A) an α-olefin oligomer having 16 to 40 carbon atoms obtained by a process comprising oligomerizing an α-olefin, having 2 to 20 carbon atoms, in the presence of a metallocene catalyst; (B) a hydrogenated derivative of the α-olefin oligomer (A); (E) an α-olefin oligomer having 16 to 40 carbon atoms obtained by a process comprising adding, in the presence of an acid catalyst, an α-olefin having 6 to 8 carbon atoms to a α-olefin dimer comprising a vinylidene bond obtained by a process comprising dimerizing an α-olefin having 2 to 20 carbon atoms, in the presence of a metallocene catalyst; and (F) a hydrogenated derivative of α-olefin oligomer (E); and wherein the first base oil is present in the composition in an amount of from 20 to 40 mass %, and the second base oil is present in the composition in an amount of from 43.4 to 63.4 mass %.
