How many kilometers should the differential oil be changed for the Mercedes GLK300?
1 Answers
Mercedes GLK300 differential oil should be changed every 30,000 kilometers. The role of differential oil in protection: Differential oil is a lubricant specifically developed for lubricating the rear differential of rear-wheel-drive vehicles, effectively providing certain protection to the differential. During continuous high-load driving, the temperature of the gear oil in the transmission and differential can sometimes exceed 120 degrees Celsius. Under high-temperature conditions, the lubricating performance of the differential oil decreases, leading to deterioration of the gear oil. Excellent thermal stability: Increased friction between gears in the differential structure can raise the vehicle's fuel consumption and, over time, damage components such as the differential and differential lock. In addition to its functions of lubrication, anti-wear, and cooling, differential oil also offers better thermal stability compared to engine oil.
