NOVELTY - A biodegradable plant-based wear-resistant lubricating oil comprises 20-35 pts. wt. low-viscosity plant-based polyolefin base oil, 60-80 pts. wt. high-viscosity plant-based polyolefin base oil, and 1-3 pts. wt. modified molybdenum disulfide. USE - Biodegradable plant-based wear-resistant lubricating oil. ADVANTAGE - The modified nano-molybdenum disulfide enables the lubricating oil to have excellent anti-wear and anti-friction performance, and can effectively reduce the friction between the engine components, improve gasoline mileage and durability, ensure the engine to exert the performance. The selected plant-based polyolefin base oil is environmentally-friendly. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of the biodegradable plant-based anti-wear lubricating oil, which involves: (a) mixing low-viscosity plant-based polyolefin base oil, high-viscosity plant-based polyolefin base oil, and modified molybdenum disulfide.
