Is transmission oil the same as engine oil?

Transmission oil and engine oil are different. Oil is the lubricating oil used in the engine system. It has anti-wear, anti-oxidation and anti-corrosion properties, which can increase the service life of the engine. The transmission oil can lubricate and prolong the service life of the transmission system device, and can also keep the gear system clean to ensure the normal operation of the transmission.

in function. Transmission oil is a special oil specially used in the transmission, not only the lubricant of the planetary gear, but also the hydraulic oil of the shifting device, and also the special oil of the transmission. Oil, known as the "blood" of the car, can lubricate the engine to reduce wear, shock absorption and shock, and seal and prevent leakage.

Features are different. Transmission oil has appropriate viscosity, good anti-foaming and anti-wear properties, good rust and corrosion resistance. The oil has a proper viscosity, and has a certain degree of anti-oxidation, anti-wear, anti-corrosion, viscosity-temperature and other properties.

Requirements are different. When the system is working, the gears in the system are rubbed, which requires lubrication, and the transmission oil just plays this role. During the operation of the gearbox, its internal temperature can be as high as 170°C, the speed of the oil can reach 20m/s, and it is constantly in contact with air and non-ferrous metals, so the anti-oxidation requirements of the gearbox oil are relatively high. The requirements of the engine oil for the engine are that the volume does not need to be too large, the weight needs to be light, and the output power is relatively large, so the pressure on the friction surface of its unit is relatively large. In addition to this, it is also affected by combustion, so the temperature of the friction surface is high.
