NOVELTY - A lubricating oil composition comprises 0.5-3 wt.% cooling additive, 8-15 wt.% friction modifier, 2-4.5 wt.% cleaning agent, 2-10 wt.% lubricant additives and remaining is base oil. The lubricant additive is chosen from one or more of defoamers, viscosity index improvers and high temperature antioxidants. The friction modifier is fluorinated graphene which is obtained by using liquid phase stripping method. USE - Lubricating oil composition suitable for automobile engines with high cleaning and self-cooling capabilities. ADVANTAGE - The lubricating oil composition is added with cooling additives, so the operating temperature of the automobile engine can be significantly reduced during the running process of the automobile, and the running performance of the automobile can be improved. The engine lubricating oil uses friction modifier containing fluorinated graphene and cleaning agent, so the abrasion proportion caused by friction in an engine system can be significantly reduced, and the cleaning agent can keep the interior of the engine clean.
