    摘要: A lubricating oil composition for internal combustion engines comprising a base oil containing at least one component selected from an α-olefin oligomer having 16 to 40 carbon atoms obtained by oligomerizing α-olefin(s) having 2 to 20 carbon atoms using a metallocene catalyst, and the hydrogenated derivative thereof, an α-olefin oligomer having 16 to 40 carbon atoms derived from an α-olefin dimer obtained using a metallocene catalyst, and the hydrogenated derivative thereof; and the like. The lubricating oil composition has an excellent low-temperature fluidity,a low evaporativity, and a good oxidation stability.
