Be cautious not to use hypoid gear oil in regular vehicle gears; replace gear oil regularly according to quality standards. Change the gear oil while the engine is warm, draining the old oil completely. Select the appropriate gear oil based on the user manual. Clean the gears and gear box with diesel. During the磨合 period, use high-grade gear oil, then switch to regular gear oil.

Ensures the normal operation of equipment, reducing wear on gears and other moving parts. Extends the service life of relevant components. Reduces the friction system to decrease frictional force, minimize power loss, and enhance efficiency, as well as lower energy consumption. Dissipates heat and provides cooling. Reduces vibration, diminishes noise levels, and alleviates the impact between gears. Washes away dirt and solid particles on gear surfaces, decreasing abrasive wear. Prevents corrosion and rust.

Reduce friction to prevent jamming and hard friction damage to parts. Also, it can reduce heat generation.

The contact stress in the tooth meshing section varies greatly, and the relative sliding speed is also significant. The lubricating oil used for transmission and rear axle gear drive mechanisms is commonly referred to as gear oil. The axes of the gears are positioned differently, and the tooth shapes vary. Therefore, different types and varieties of gear oil are required.

The old classification of vehicle gear oils in China was based on the former Soviet Union's specifications, categorizing general-purpose gear oils according to their kinematic viscosity at 100 degrees Celsius into three grades: 20, 26, and 30. Hypoid gear oils were divided into four grades based on their kinematic viscosity at 100 degrees Celsius: 18, 22, 26, and 28. Currently, they are categorized by quality into three types: General Vehicle Gear Oil (CLC for medium load vehicles), CLD Heavy Load Vehicle Gear Oil, and CLE.
