The newly bought gear oil with running-in horsepower cannot be used. Be sure to change the transmission oil after the running-in period of the new car. Because the gears of the new car are not well run-in, the surface of the gears will be uneven, and the running-in between gears will produce metal powder sinking into the lubricating oil, so the lubricating oil mixed with metal powder should be replaced. When changing oil, viscosity is the most basic selection factor of gear oil. If the viscosity is too large, it will overheat the friction surface and cause unnecessary power loss.

The function of gear oil

In order to effectively improve the power efficiency of gear-driven engine, prevent the corrosion and rust of gears and parts, reduce the noise of gearbox and reduce the vibration and impact between gears, good viscosity can reduce the wear of gear surface and prolong the service life of gears, gear oil can reduce the wear of gears and other moving parts and prolong the service life of gears, gear oil can reduce friction and power loss, and can dissipate heat and play a certain cooling role.
