NOVELTY - Graphene-containing lubricating oil comprises 0.1-1 pt. wt. graphene, 72-85 pts. wt. synthetic base oil, 0.8-3.2 pts. wt. composite antioxidant, 0.5-1.5 pts. wt. metal cleaning agent, 2.3-6.5 pts. wt. ashless dispersant, 0.05-1.5 pts. wt. nano-scale friction modifier, 2.0-10.0 pts. wt. viscosity index modifier, 0.2-1.0 pt. wt. pour-point depressant, and 50 ppm antifoaming agent. USE - Graphene-containing lubricating oil. ADVANTAGE - The graphene-containing lubricating oil solves the prior art corrosion and selectivity problems and has improved ultrasonic dispersion and reduced amount of graphene. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of graphene-containing lubricating oil comprising adding synthetic base oil into a blending kettle, stirring at 60-65 degrees C, sequentially adding pour-point depressant, viscosity index improver, composite antioxidant, metal cleaning agent, ashless dispersant and nano-scale friction modifier, stirring uniformly, adding graphene and antifoaming agent, keeping the original temperature and uniformly stirring for half an hour, standing for half an hour, and obtaining the product.
