Abstract
The invention relates to a composite additive applied to engine oil. The composite additive is composed of base oil, an antioxidant, a dispersant, a cleaning agent, a corrosion inhibitor, a foaming inhibitor, a metal passivator, a demulsifying agent, a viscosity index improver, an extreme pressure additive, tungsten oxide powder, and molybdenum oxide powder. The composite additive has the advantage of simple production method, waste oil is biodegradable, an environmental protection requirement is completely reached, the usage period of a product is longer, antiwear and anti-extreme pressure efficacies of lubricating oil are improved; a plurality of efficacies of oxidation resistance, corrosion resistance and foaming resistance of the lubricating oil are increased simultaneously, a cleanliness efficacy of the lubricating oil can be maintained for a long term, and the comprehensive efficacy of the lubricating oil of an engine can be completely enhanced.
