Document Type and Number:
WIPO Patent Application WO/2013/145037
Kind Code:
A1
Abstract:
The present invention relates to a lubricating oil composition for an internal combustion engine which has excellent fuel efficiency and heat resistance, and more specifically to a lubricating oil composition for an internal combustion engine which is characterized by containing, in a mixed-base oil (AB) which is a mixture of a base oil (A) which is a mineral oil and/or a synthetic oil with a kinematic viscosity at 100°C of 3.5 mm2/s or less and a base oil (B) which is a mineral oil and/or a synthetic oil with a kinematic viscosity at 100°C of over 3.5 mm2/s, the percentage of the base oil (A) in the total base oil being 40 mass% or less, 0.05 to 0.5 mass% of a calcium salicylate-based cleaning agent (C) in terms of calcium content based on the total amount of the composition, and 0.002 to 0.2 mass% of a calcium sulfonate-based cleaning agent (D) in terms of calcium content based on the total amount of the composition.
