How Often Should Gear Oil Be Changed in a Car?
1 Answers
The gear oil in a car generally needs to be replaced every 40,000 kilometers. The specific replacement interval should be based on the manufacturer's recommendations, as the service life of gear oil is influenced by factors such as the vehicle model, oil quality, usage conditions, and driving habits. Gear oil typically possesses the following essential properties: 1. Appropriate viscosity and good viscosity-temperature characteristics—viscosity is the most fundamental property of gear oil. 2. Sufficient extreme pressure and anti-wear performance. 3. Good demulsibility. 4. Excellent oxidation stability and thermal stability. 5. Effective anti-foaming properties. 6. Strong rust and corrosion prevention.
