NOVELTY - Lubricating oil comprises 30-40 pts. wt. poly- alpha -olefin, 15-20 pts. wt. fluorosilicone oil, 1.5-4 pts. wt. pentaerythritol ester, 2-5 pts. wt. modified nanodiamond, 1-3 pts. wt. castor oil, 3-6 pts. wt. graphene, 1-3 pts. wt. molybdenum disulfide, 0.4-0.8 pts. wt. Tweens (RTM: Polysorbate), 0.5-1.2 pts. wt. sorbitan monooleate, 0.2- 0.6 pts. wt. antioxidant, 0.4-0.8 pts. wt. anti-emulsifier and 0.7-1.5 pts. wt. viscosity index improver. USE - The lubricating oil is useful for mechanical equipment (claimed). ADVANTAGE - The lubricating oil: has excellent viscosity, lubricity and oxidation resistance, wear resistance and durability. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for producing the lubricating oil, comprising (i) taking all the raw materials of the lubricating oil, (ii) mixing and stirring the poly- alpha -olefin, fluorosilicone oil, pentaerythritol ester and castor oil, and placing in an ultrasonic disperser for high-frequency dispersion at 55-60 degrees C for 20-30 minutes, (iii) adding the remaining raw materials to the mixture in the step (ii), heating to 40-45 degrees C, and stirring and mixing the mixture at a speed of 800-1000 revolutions/minutes (rpm) for 20-30 minutes, and placing in an ultrasonic disperser for 15-20 minutes, cutting with a high-speed shear for 3-4 hours, shearing at 50-55 degrees C, and naturally cooling to room temperature.
