Adopting imported base oil + imported additives to improve the high temperature antioxidant performance of the oil. Add high quality index improver to maintain viscosity stability and shear performance. Effectively improve the friction to reduce the engine running resistance, reduce the generation of deposits, keep the engine internal clean, to avoid abnormal damage to the parts. Low carbon and environmental protection in line with national emission standards. It has excellent anti-heat load performance to maintain good lubrication of engine parts under high temperature environment, and the oil is not easy to deteriorate.
