NOVELTY - Graphene automobile engine oil comprises 500 g base oil, 7-12 g graphene, 1-2 g detergent, 1-1.5 g dispersant, 2-3 g oxidation and corrosion inhibitor, 3-5 g oiliness agent, 10-12 g viscosity index improver, 0.5-1 g antirust agent, and 2-4 g antifoaming agent. USE - Used as graphene automobile engine oil. ADVANTAGE - The method quickly and simply produces graphene, meets need of engine oil production, and improves mixing efficiency of base oil and graphene. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing graphene automobile oil, comprising (i) sieving the base oil using polymer filter membrane, and filtering the impurities in the base oil, (ii) crushing, grinding, sieving, mixed solution and chemical reduction of the graphite block to obtain graphene, (iii) mixing automobile oil with base oil, graphene, detergent, dispersant, oxidation and corrosion inhibitor, oiliness agent, viscosity index improver, rust inhibitor and anti-foaming agent.
