NOVELTY - Lubricating oil comprises 80-90 pts. wt. base oil, 3-6 pts. wt. lithium hydroxide, 8-14 pts. wt. stearic acid, 1-2 pts. wt. aluminum isopropoxide, 0.6-0.7 pts. wt. benzoic acid, 0.25-0.5 pts. wt. graphene oxide, 0.2-0.4 pts. wt. nano tin, 0.05-0.1 pts. wt. coupling agent, 3-5 pts. wt. polyisobutene and 2-2.5 pts. wt. water. USE - Used as lubricating oil. ADVANTAGE - The oil has excellent high temperature wear resistance, and reduces the friction loss. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing the lubricating oil, comprising (i) mixing the lithium hydroxide and the first part of stearic acid to obtain lithium-based thickening agent, (ii) mixing the aluminum isopropoxide, benzoic acid, residual stearic acid, the first part of base oil and water to obtain the aluminium base oil, (iii) mixing the graphene oxide, nano tin and coupling agent to obtain modified graphene, and (iv) mixing the lithium-based thickening agent, aluminum base oil, modified graphene, polyisobutene and residual base oil.
