Abstract

The invention relates to pedal motorcycle special-purpose long-life low-noise lubricating oil. The pedal motorcycle special-purpose long-life low-noise lubricating oil at least comprises 5.8%-7.8% of a gasoline-engine oil compound, 0.8% of an antioxidant, 1.1%-1.3% of an anti-wear friction reducer, 3.5%-4.5% of a viscosity index improver and 86.6%-87.8% of mixed base oil. The lubricating oil also comprises a compound anti-foaming agent. The gasoline-engine oil compound comprises an ashless dispersant and a total calcium-based detergent. The anti-wear friction-reducing agent is one or more of molybdenum dialkyldithiocarbamate, a molybdate and a molybdenum-amine complex. The viscosity index improver is ethylene-propylene copolymer liquid sol. Compared with the commercial oil, the lubricating oil needs longer time in consumption of the same amount of oxygen and has good oxidation resistance and abrasion resistance and a long service life. The pedal motorcycle using the lubricating oil has low noise and friction.

Description

technical field [0001] The invention relates to the field of lubricating oil, in particular to a special long-life and low-noise lubricating oil for scooter motorcycles. Background technique [0002] Among modern means of transportation, motorcycles have entered people's lives earlier. With the rapid development of the automobile industry, the number of existing motor vehicles in my country has reached 264 million; among them, the number of motorcycles is 160 million. Motorcycles can be divided into: straddle bikes, underbone bikes, small scooters, large scooters, etc. according to their models. Among the motorcycles, the scooter is welcomed by consumers because of its safety, comfort and speed among people's travel vehicles. In the past, motorcycle engines have always used automobile engine oil, and the working conditions of motorcycles and automobile engines have many differences, the most prominent being high temperature, high speed, clutches are divided into wet clutch...
