NOVELTY - Producing engine oil additives comprises (i) separately grinding the graphene material and white carbon black, and sieving to obtain graphene powder and white carbon black powder, (ii) mixing the graphene powder and white carbon black powder obtained in the step (i) according to the mass ratio of 1:1, and (iii) dissolving the mixture of graphene and white carbon black obtained in the step (ii) in the base oil. USE - The method is useful for producing engine oil additives. ADVANTAGE - The additives: improves the dispersibility of the graphene material in the engine oil.
