How Often Should Car Gear Oil Be Changed?
1 Answers
Car gear oil should be changed every 40,000 kilometers. The specific replacement interval should be determined based on the manufacturer's recommendations, as the service life of gear oil depends on factors such as the vehicle model, oil quality, usage conditions, and driving habits. Gear oil is a high-viscosity lubricant specifically designed to protect power transmission components and typically has a strong sulfur odor. Vehicle gear oil is classified by performance and viscosity. Currently, the American Petroleum Institute (API) performance classification and U.S. military gear oil specifications are widely adopted worldwide.
