Abstract
The lubricating oil composition of the invention comprises a lubricant base oil, a 3,4,5-trihydroxybenzoic acid ester at 5-5000 ppm by mass, and a phosphorus compound at 0.001-10.0% by mass, based on the total mass of the lubricating oil composition. The lubricating oil composition of the invention significantly lowers wear and exhibits a stable low frictional coefficient, while having a high rust-preventing effect for iron-based sliding sections. The lubricating oil composition of the invention is therefore suitable for prolonged use, and exhibits a notable effect for energy savings as well due to its stable low frictional coefficient property.
