Hydraulic oil can not be used as lubricant oil.
1. Hydraulic oil is mainly used in all kinds of hydraulic oil systems. Its viscosity grade is determined by the working condition of hydraulic system. The additives used are anti-oxygen, anti-rust, anti-wear and so on, which are quite different from internal combustion engine oils. Therefore, we must not use hydraulic oil as oil.
2. In the field of application, hydraulic oil is mainly used in the field of industrial lubricating oil, while oil is generally used in the field of automobile, which is some difference in the field of use. From the external color point of view, the hydraulic oil color is generally golden transparent body, while the oil is relatively blue in color.
3, from the point of view of manufacturing, the general hydraulic oil is a semi-finished oil, they have a remarkable characteristic of high pressure resistance, the manufacturing process is slightly worse than the oil. One of the most remarkable features of oil is lubrication. The internal microstructure of oil is smaller than that of hydraulic oil, and its viscosity is generally higher than that of hydraulic oil.
