Why should the dry dual clutch transmission oil never be changed?Dry dual clutch transmission oil change

It is not that the dry dual clutch transmission oil cannot be replaced, but it should be replaced carefully. When replacing the dry dual clutch transmission oil, special transmission lubricants need to be used. This type of gearbox has a very high temperature and fast running speed during operation, and needs to be replaced regularly so that it will not affect normal use.

The effect of not changing the transmission oil for a long time

Once it is not replaced for a long time, the gearbox oil will deteriorate, and the volatilization will cause excessive wear of the internal parts of the gearbox, which will affect the service life of the gearbox. Therefore, the lubricating oil of the dry dual-clutch gearbox of the motor vehicle needs to be replaced regularly, and the replacement time is generally two years or 40,000 kilometers after the vehicle has been driven.

Dry dual clutch transmission oil replacement method

There are many ways to replace the transmission oil. The transmission oil can be replaced by gravity oil change, the transmission oil can also be replaced by the circulating machine, or the transmission oil can be replaced by removing the oil pan. , The amount of gearbox lubricating oil replaced by different oil changing methods is different.

The difference between different oil changes

1. The method of gravity oil change is relatively low cost, and the replacement process is faster. The oil change method of gravity oil change can only replace about 50% of the gearbox lubricating oil.

2. Use the circulator to replace the gearbox lubricating oil, the oil discharge rate can reach 80%, the replaced oil is relatively clean, and the replacement operation of the circulator is relatively long, and once the intermediate operation is wrong, it may lead to failures.

3. The price of using the dismantling oil pan to change the gearbox lubricating oil is moderate, the oil replacement rate can reach about 80%, the operation time is relatively complicated, and the replacement time is long.

When replacing the motor vehicle gearbox lubricating oil, it should be selected according to individual needs. When operating in different ways, the replacement time, operation method, and replacement price will change.
