Is the gearbox oil still usable after 9 years?

For transmission oil that has not been changed for a long time, we need to carefully evaluate its availability and impact.Transmission fluid quality degrades over time, which can adversely affect your car's performance. According to experience, transmission oil that has not been changed for up to 9 years may accumulate a large amount of harmful substances and impurities.

In addition, if the transmission oil has not been changed for a long time, its viscosity and cleanliness will be affected. Transmission oil should have good lubricity, clean gear system and heat dissipation function, but transmission oil that has not been changed for a long time may not meet these requirements. The result is a stuck or unsmooth feeling when shifting gears, which is very uncomfortable for the driving experience.

So, when the transmission fluid is 9 years old, we recommend considering changing it. Regularly changing the transmission oil can maintain the good control performance of the transmission and improve driving safety and driving comfort. For most vehicles, it is a reasonable recommendation to change the transmission oil every 3 years or about 80,000-100,000 kilometers.

Considering the importance of transmission oil, we strongly recommend that car owners develop the habit of regular inspection and timely replacement of transmission oil. Choose a regular and professional maintenance organization for replacement to ensure that the quality and specifications of the selected transmission oil meet the requirements of the model, thereby extending the service life of the transmission device.
