Automobile gear oil is a kind of maintenance oil commonly used in car maintenance. It is mainly used in various gear transmission devices. Its functions are to lubricate, reduce gear wear, prevent parts from sintering, help the gear to dissipate heat and prevent it from being corroded by dirt. . So, in general, how many kilometers should the car gear oil be changed?
Gear oil generally needs to be replaced after the car travels 60,000-80,000 kilometers, and some special models may need to be replaced after 20,000-40,000 kilometers. If you want to know how many kilometers you have driven, you need to replace the gear oil. You can decide according to the maintenance manual that comes with the vehicle, or you can decide the replacement frequency according to the viscosity of the gear oil, the location of use, etc.
Generally speaking, gear oil can be divided into transmission oil and rear axle lubricating oil according to the purpose. Transmission fluids can be divided into two categories, namely automatic transmission fluids and manual transmission fluids. Different from the free gearbox, the replacement cycle of the gear oil in the manual gearbox is longer. Generally, it needs to be replaced after the car has traveled 60,000 to 80,000 kilometers.
The replacement cycle of the rear axle lubricating oil is related to the quality of the gear oil, the number of kilometers driven and the driving conditions of the car. Generally speaking, the rear axle lubricating oil needs to be replaced after the car has traveled 20,000-30,000 kilometers. In addition, it is also possible to decide whether to replace the rear axle oil according to the service life. The service life of the rear axle oil is three years, and it can be replaced after three years. If the gear oil is not replaced in time, the working efficiency of the gear will be reduced in light, and the gear parts will be damaged in severe cases, which must be paid attention to.
