What details should be paid attention to when using gear oil

The viscosity selection of automobile gear oil has a definite impact on the fuel economy of automobiles. Therefore, under the appropriate ambient temperature, low-viscosity multi-stage vehicle gear oil should be used as far as possible to meet the lubrication requirements of the vehicle gearbox, and can also play a better oil-saving effect. Especially in northern winter, gear oil with good low-temperature fluidity and suitable for the local ambient temperature should be selected; During overhaul and running-in, the viscosity of vehicle gear oil should not be too high

When it is difficult to start in winter, replace low-viscosity multi-stage vehicle gear oil in time. It is forbidden to bake the rear axle and transmission to avoid serious deterioration of gear oil, such as colloid or carbon deposit

Low quality automotive gear oil cannot be used for vehicles with higher requirements, that is, ordinary automotive gear oil cannot replace medium and heavy duty automotive gear oil for hyperboloid gears, otherwise it will cause equipment wear and shorten service life; However, higher gear oil can be used for vehicles with low requirements. Add gear oil properly, if too much, it will not only increase the mixing resistance and fuel consumption, but may even make the gear oil leak to the hub bearing through the rear axle half shaft seal ring, forming a dilution of bearing grease, thus causing mechanical failure; Too little will also cause poor gear lubrication, and too high temperature will accelerate gear wear and oil oxidation. Generally, the gear oil level should be added to the level of the bottom edge of the fuel port of the gear box. It is necessary to frequently check the gear oil tank for leakage and ensure that each oil seal and gasket is intact
