Disclosed is a lubricating oil composition for use in a marine piston engine. The composition comprises the following components by mass percentage: 1-15% of alkyl sulfonate detergent, 1-15% of alkyl salicylate detergent, 0.1-5% of synthesized polyether, 0.1-5% of dispersant, 0.1-5% of anti-wear agent; the remainder is a Group II base oil. The lubricating oil composition for use in a marine piston engine, provided by the present invention, has good rust prevention and antioxidant properties; the alkyl salicylate detergent has a special structure, and mixes well with the unburned part of a heavy fuel, thereby effectively inhibiting the black sludge caused by the unburned part of the heavy fuel. Furthermore, since synthesized polyether is added, the lubricating oil composition for use in a marine piston engine, provided by the present invention, may be used in Group II base oils so as to cause said base oils to have better lubricating properties, thus satisfying various requirements for lubrication of marine piston engines. |
