1. The amount of lubricating oil added is not as much as possible. Because too much lubricating oil will increase the rotational resistance of the crankshaft, thereby reducing the output power of the engine.
2. Lubricating oil does not need to add additives. Because the lubricant itself is composed of base oil and additives, the formulation has been tested and screened in many ways.
3. Pay attention to distinguish the pros and cons of lubricating oil. The first is to observe the color and sediment, the lubricating oil that is clear and yellow-brown is of good quality. A cloudy or emulsified color means there is a lot of water in it. A burnt smell indicates premature oxidation or mixing with other oils. Second, the lubricating oil can be dripped on the iron plate or exhaust pipe above 110 ℃. If there is a popping sound, the lubricating oil contains water. The third is to drop the lubricating oil on the filter paper and compare with spot chromatography.
4. Select the appropriate viscosity grade according to the specific location to ensure that it can also play a normal lubricating role under the condition that the working temperature changes greatly.
5. Select lubricating oil with good oxidation resistance and stability to ensure that it is not easy to oxidize and deteriorate under high temperature and high pressure conditions, and has a long service life.
6. Choose lubricating oil with good defoaming property. Foaming from oil disappears easily under working conditions.

In general, high-quality lubricants should maintain suitable wear resistance, viscosity, corrosion resistance, and oxidation stability. Lubricating oil plays an indispensable and important role in the operation of the machine, so it needs to be filtered in time after aging and deterioration. The lubricating oil purifier produced by YUNENG can meet the above requirements. YUNENG can also produce Hydraulic Oil Filtration Machine.
