New energy vehicles do indeed need to replace gear oil. Here is a detailed answer:
1. The function of gear oil: Gear oil is mainly used for lubricating the transmission and rear axle of new energy vehicles, which can prevent wear and corrosion, help dissipate heat from gears, and maintain the cleanliness of the transmission system, thereby ensuring the normal operation of the transmission and extending the life of the transmission device.
2. Replacement cycle: The gear oil replacement cycle for new energy vehicles is generally 40000 kilometers or 2 years. However, this cycle may vary depending on the vehicle model and manufacturer, so it is recommended that car owners follow the specific regulations in the vehicle maintenance manual for replacement.
3. The importance of replacing gear oil: If gear oil is not replaced regularly, impurities may be generated in the oil due to chemical changes, causing blockages in the oil passage and affecting the shifting function. Long term high-temperature operation can also reduce the lubrication performance of gear oil, intensify the wear of clutch plates, and even cause stall phenomenon. Regularly replacing gear oil is an important measure to maintain the normal operation of the gearbox and extend the life of the transmission device.
New energy vehicles require the replacement of gear oil, and it should be strictly carried out in accordance with the regulations in the vehicle maintenance manual.
