Is differential oil the same as transmission oil?What is differential oil

Differential oil and transmission oil are the same, both are gear oil. Differential tank oil is a lubricating oil for the rear wheel differential of rear-drive vehicles, which can protect the differential to a certain extent. The transmission oil is a kind of oil products, keeping the gear system clean, can play a role in ensuring the normal operation of the transmission and prolonging the life of the transmission.

What is differential oil

Differential gear oil is a lubricating oil for the lubrication of rear wheel differentials of rear-drive vehicles, which can effectively protect the differentials to a certain extent. When the car is continuously running under high load, the differential gear oil may exceed 120 degrees, and the lubricating performance of the differential oil will decrease under high temperature conditions, which will cause the gear oil to deteriorate. If you do not pay attention to maintenance, after the performance of the differential gear oil declines, the friction force of the gears in the differential structure will increase, which will increase the fuel consumption of the vehicle, and will damage the differential and differential lock for a long time.

In order to prevent insufficient lubrication of the differential oil, it is generally necessary to replace the differential oil when the maintenance is performed at 60,000 kilometers or 40,000 kilometers. Of course, this is best to follow the arrangement of the 4S shop. After all, not all models have the same working conditions, especially for four-wheel drive, hard-line SUV models or high-performance and fast-speeding models. The lubricating effect of the gear oil must be higher, otherwise it is easy to cause damage to the differential due to insufficient lubrication.
