ABSTRACT:
Low sulfur lubricating oil compositions are provided which are extremely excellent in anti-wear properties for the valve train system of an internal combustion engine and are also excellent in long-drain properties, and thus is suitable for used in an internal combustion engine. The lubricating oil compositions comprises a lubricating base oil, (A) a specific alkali metal or alkaline earth metal salicylate and/or an overbased or basic salt of the salicylate, (B) a phosphorus-containing anti-wear agent, (C) an ashless dispersant, and (D) an ashless anti-oxidant, as the essential components, and contains boron in an amount of 0.01 to 0.15 percent by mass and sulfur in a total amount of 0.3 percent by mass or less, based on the total mass of the composition.
