The invention discloses anti-wearing extreme-pressure-resistant engine lubricating oil which consists of base oil, an antioxidant, a detergent, a dispersing agent, an extreme-pressure anti-wearing agent, a viscosity index improver, a nano-grade rhenium-molybdenum alloy powder material, polyacrylate, an ethyoxyl phenol, benzotriazole and vulcanized dipolybutylene, wherein the antioxidant is an thioether liquid of shielding phenol; the detergent is sulfurized alkyl phenate; the dispersing agent is a styrene ester derivative; the extreme-pressure anti-wearing agent is a composite ester of a high molecular weight; the viscosity index improver is a styrene diene copolymer. The anti-wearing extreme-pressure-resistant engine lubricating oil has the advantages of being scientific in preparation scheme and simple in preparation method, the price of a prepared product is lower than that of a similar product, various property requirements of the anti-wearing extreme-pressure-resistant engine lubricating oil can be effectively and comprehensively improved, the oxidation resistance, the corrosion resistance, the detergence and dispersity, the anti-rusting property, the bubble resistance and the greasy sludge prevention property of the anti-wearing extreme-pressure-resistant engine lubricating oil can be comprehensively improved, the effects of wearing resistance and extreme pressure resistance can be improved to the maximum extent, meanwhile a very good remediation function on a wearing surface of an engine can be achieved, the lubricating oil change period can be prolonged, the noise can be reduced, and the exhaust gas emission can be reduced.
