Lubricating oil composite

The invention relates to a lubricating oil composite comprising the components in percentage by weight: 2.0-10.0% of high-temperature detergent, 2.0-10.0% of ashless dispersant, 0.2-2.0% of antioxidant antiwear agent, 0.5-3.0% of auxiliary antioxidant, 0.1-0.8% of pour point depressant, 5.0-10.0% of viscosity index improver, 0.0015-0.0025% of anti-foaming agent and the balance of hydrogenation technology base oil. The lubricating oil composite has the characteristics of easy obtaining of raw material, simple production technology and convenient modulation, can furthest reduce faults of a diesel engine due to lubrication, prolongs the service life of the engine and has excellent soot disperse property; oil shows excellent high-temperature detergency, polishing property resistance and the effects of antioxidant and thickening by optimizing the high-temperature detergency and the antioxidant antiwear agent. The main property reaches ACEA E4 and API CH4 quality grades and satisfies the oil consumption requirement
