The invention relates to a novel lubricating agent comprising the following components: 90-95 parts of base oil, 2.8-3 parts of polymethacrylate, 3-3.5 parts of base zinc salt of dioctyl thiophosphate, 1-1.2 parts of trihydroxybenzoic acid, 1-1.5 parts of dialkenyl succinimide, 0.8-1 part of phenylalanine, 1-1.5 parts of calcium sulfonate, 0.8-1.2 parts of graphite powder, 3.2-3.5 parts of modified molybdenum disulfide, 2-2.5 parts of naphthylphenyl phosphate and 1.5-1.8 parts of polyvinyl n-propyl ester. According to the technical scheme, all the components take a synergistic effect, so that the performance of the base oil is improved; and all the components can be uniformly dispersed, so that the lubricating property of the lubricating oil is good, and particularly the wear resistance and high-temperature resistance are remarkable.
