Abstract

Disclosed is a lubricant composition for internal combustion engines which comprises a base oil containing at least one substance selected from an a-olefin oligomer having 16-40 carbon atoms which is obtained by oligomerizing an a-olefin having 2-20 carbon atoms by using a metallocene catalyst, a hydrogenated product of such an a-olefin oligomer, an a-olefin oligomer having 16-40 carbon atoms which is derived from an a-olefin dimer obtained by using a metallocene catalyst, a hydrogenated product of such an a-olefin oligomer and the like. This lubricant composition for internal combustion engines is excellent in low-temperature fluidity, while having low evaporativity and good oxidation stability.

Description

technical field

[0001] The present invention relates to a lubricating oil composition for an internal combustion engine, and more specifically, to a lubricating oil composition for an internal combustion engine having excellent low-temperature fluidity, low evaporation, and excellent oxidation stability. Background technique

[0002] In order to save energy, improving the fuel consumption of vehicles is one of the most important issues. As a countermeasure against global warming, CO 2 Reduction considerations are also important for humans.

[0003] As a fuel-saving measure for internal combustion engine oil (lubricating oil for internal combustion engine), it is known that reducing the viscosity (reducing the viscosity) is effective in order to reduce the friction loss due to the internal combustion engine oil. However, if the viscosity of the internal combustion engine oil is reduced, the wear resistance that the internal combustion engine oil should have decreases, and t...
