NOVELTY - Graphene lubricating oil comprises 0.001-0.5 wt.% graphene powder, 1-7.5 wt.% dispersant and suspension mixture and 90-92 wt.% automobile lubricating oil. USE - Graphene lubricating oil is useful for automobile engine. ADVANTAGE - The graphene lubricating oil has high dispersibility and stability, improves abrasion resistance and mechanical protection performance of the automobile engine, effectively reduces the emission of carbon monoxide and hydrocarbon compounds in automobile engine, and saves fuel consumption. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for the method for preparing the graphene lubricating oil, which involves adding graphene powder to a mixer, adding dispersant and suspension mixture to the mixer, uniformly mixing the dispersant and suspension mixture and graphene powder to obtain an uniform graphene dispersion, adding the graphene dispersion to the automobile lubricating oil, and uniformly mixing under stirring condition to obtain the graphene lubricating oil.
