How many kilometers should the Qiao Ge change the gear oil?

[MacLilah]

After 500 kilometers, the Qiao Ge should change the engine oil every 1000 kilometers, and change the gear oil every two engine oil changes. Benefits of changing gear oil: Reduce the wear of gears and other moving parts, and extend the life of gears. Reduce friction and power loss. Disperse heat and play a certain cooling role. Prevent corrosion and rust. Reduce working noise, vibration and impact between gears. Flush away dirt, especially the dirt between the tooth surfaces, and reduce wear. Selection of gear oil: The selection of viscosity should consider both the temperature of the area where it is used and the anti-wear and transmission properties. Use 75W oil in winter and 90 oil in summer. The difference in viscosity is only to consider the anti-wear and transmission properties, while the lower viscosity gear oil in the manual transmission makes the feeling of shifting gears when the car is cold much better, but the anti-wear and noise are sacrificed a lot.
