1. The gasification of hydraulic oil for shock absorber should be as small as possible. When the car is running, the hydraulic oil evaporates with the increase in temperature, and the hydraulic oil with small vaporization makes the service life longer and the shock absorption effect is good. At the same time, it satisfies various use environments and has a wide range of use.
2. The freezing point of shock absorber hydraulic oil is low. The lower freezing point allows the shock absorber to run normally in the cold climate in the north, and it is generally required to be lower than -40 degrees Celsius. At the same time, it has good viscosity index and viscosity-temperature performance.
3. Cleanliness of shock absorber oil. Clean hydraulic oil can reduce the wear of the shock absorber, ensure the shock absorption effect and increase its service life
4. The shock absorber oil must have anti-rust and anti-wear effects, and protect the shock absorber from rust and wear damage.
5. The shock absorber oil must have good working stability, anti-air-gas mixing stability, and anti-oxidation stability
