Why is it not recommended to change the rear axle oil of a car?
1 Answers
Here is the relevant introduction about the rear axle oil of a car: 1. Lubrication effect: Rear axle oil is gear oil, which not only provides excellent lubrication but also has a certain cooling effect. If the rear axle oil is not changed for a long time, it may deteriorate, and naturally, it can no longer protect the rear axle gears, thereby accelerating gear wear and even seriously affecting the car's fuel economy. 2. Replacement cycle: There is no fixed interval for changing rear axle oil; it depends on the car's driving conditions and environment. Additionally, different oil brands may have varying intervals, generally around 20,000-30,000 km. For new cars, the rear axle oil should be changed during the 12,000 km maintenance, and then checked every 24,000 km thereafter. If obvious discoloration or thinning is observed, it should be replaced immediately.
