How Often Should Gear Oil Be Changed in a New Car?

[VanAliyah]

New car gear oil should be changed every 40,000 kilometers or every two years. Once it exceeds 20,000 kilometers, you need to pay attention. As long as gear shifting is smooth and there is no significant change in transmission noise, you don’t need to worry too much. The actual replacement interval and mileage for gear oil depend on factors such as the driver’s proficiency in vehicle operation, the road conditions the vehicle frequently encounters, the mileage covered within a certain period, and frequent high-speed driving. Functions of automotive gear oil: 1. Excellent oxidation stability and thermal stability; 2. Appropriate viscosity and good viscosity-temperature characteristics; 3. Good anti-foaming and anti-emulsification properties; 4. Sufficient extreme pressure anti-wear performance; 5. Good rust and corrosion resistance.
