Does Differential Oil Never Need to Be Replaced?

[AshlynLee]

Automotive differential oil does require replacement, typically every three years or 60,000 kilometers. Differential oil serves as a lubricant, providing lubrication and protection to the differential. Here are the specific details: 1. Consequences of not replacing differential oil: The car differential is a mechanism that allows the left and right or front and rear drive wheels to rotate at different speeds; failure to replace the differential oil in time can cause the differential to malfunction, leading to severe consequences during turns, such as vehicle rollover or instability. 2. Function of differential oil: Differential oil is a lubricant specifically developed for the lubrication of the rear-wheel differential in rear-wheel-drive vehicles, effectively providing certain protection to the differential.
