Abstract
The invention discloses a dibutyl cis-butadiene diacid ester engine oil composition. The dibutyl cis-butadiene diacid ester engine oil composition is prepared through adopting castor based dioctyl sebacate and oil-soluble polyether as base oil and enabling the base oil to be matched with a variety of compound additives, including an antioxidant preservative, an antifoamer, a viscosity index improver, a metal deactivator, a friction modifier, a detergent, a dispersant, an antioxidant, a rust preventive, an oily agent and a reinforcer. The engine oil composition disclosed by the invention has excellent cleaning and dispersion properties and viscosity-temperature characteristics, can control the generation of polar substances, such as high and low-temperature oil sludge and the like, has excellent fuel dilution resistance, filterability and solubilization property and can keep an engine clean and a lubricating oil system smooth; the engine oil composition has good high-temperature oxidation stability, soot solubilization capability, wear resistance, shearing resistance and antifriction and corrosion resisting properties, and the low-temperature startability is good, so that the generation of carbon deposits and paint films of the engine at high temperature can be reduced, the abnormal wear and bearing bush corrosion of the engine during start-up and acceleration are prevented, and the service life and oil drain interval of the engine are prolonged.
