Gearbox oil plays a vital role in the gearbox of a car. It is not only a lubricant between the various components inside the gearbox, but also has multiple functions such as cooling, cleaning, and sealing. It plays an important role in maintaining the normal operation of the gearbox and improving the performance of the vehicle.One of the main functions of gearbox oil is lubrication. The gearbox contains many precision gears, bearings, synchronizers and other components, which generate a lot of friction and heat when running at high speed. Gearbox oil can form a protective film between these components to reduce friction and wear, thereby extending the service life of the gearbox.In addition to lubrication, gearbox oil also has the task of cooling. During the operation of the gearbox, a lot of heat is generated due to friction and interaction between components. Gearbox oil can absorb and take away this heat through circulation, maintain the stability of the internal temperature of the gearbox, and prevent failures caused by overheating.Gearbox oil also has a certain cleaning function. It can take away impurities such as metal debris and dust inside the gearbox, prevent these impurities from damaging the gearbox components, and keep the inside of the gearbox clean.In addition, gearbox oil can also form a certain pressure inside the gearbox, improve the sealing performance of the gearbox and prevent oil leakage. This is essential for maintaining the normal working pressure and oil circulation of the gearbox.When selecting and replacing gearbox oil, you need to pay attention to the following points. First, you should consult the vehicle manual or contact the manufacturer to find out the type of gearbox oil suitable for your vehicle and the recommended replacement cycle. The gearbox oil requirements of different brands and models may vary.Secondly, when replacing gearbox oil, you should choose a well-known brand of gearbox oil with reliable quality to ensure the performance and quality of the oil. At the same time, pay attention to the viscosity grade of the gearbox oil to meet the lubrication and cooling performance required by the vehicle.Finally, the replacement cycle of gearbox oil varies depending on the model and the use environment. Generally speaking, the gearbox oil replacement cycle for automatic transmission models is 40,000 to 60,000 kilometers, and for manual transmission models it is 60,000 to 80,000 kilometers. If the vehicle is used less frequently, the gearbox oil can also be replaced according to time.In short, gearbox oil is an important part of keeping the gearbox running normally. Correct selection and replacement of gearbox oil is of great significance to extending the life of the gearbox and improving vehicle performance.
