    摘要: The invention relates to a lubricating oil composition for an internal combustion engine excellent in fuel saving property and heat resistance property, more specifically to a lubricating oil composition for an internal combustion engine containing a mixed base oil (AB) comprising a mixture of a base oil (A) being a mineral oil and/or a synthetic oil with a kinematic viscosity at 100°C of not more than 3.5 mm 2 /s and a base oil (B) being a mineral oil and/or a synthetic oil with a kinematic viscosity at 100°C of more than 3.5 mm 2 /s, wherein the ratio of the base oil (A) to the entire base oil is not more than 40 mass%, a calcium salicylate-based detergent (C) in 0.05 mass% to 0.5 mass% as a calcium amount based on the total amount of the composition, and a calcium sulfonate-based detergent (D) in 0.002 mass% to 0.2 mass% as a calcium amount based on the total amount of the composition.
