What are the filter paper requirements for oil filters?

The oil filter has higher requirements for filter paper than the air filter, and the temperature changes from 0 to 300 degrees. Under the severe temperature change, the concentration of the oil also changes accordingly, which will affect the filter flow of the oil. . The filter paper of the high-quality oil filter can filter impurities and ensure sufficient flow under severe temperature changes.

The filter paper of the fake and inferior oil filter is of poor material, and it is immersed in the oil for a long time. The filter paper itself has poor filtering effect under the environment of high temperature and high pressure. At the same time, it also produces a large amount of paper dust, which causes the oil circuit of the engine lubrication system to block or cause parts and components. Abnormal wear, in severe cases, the engine will not be oiled, resulting in serious damage or scrapping of the engine. The gasket of the sealing part of the fake oil filter has poor rubber toughness and is easy to age and crack at high temperature. Therefore, the oil is easy to jump out from the joint surface of the machine filter and the cylinder block, resulting in oil leakage, poor engine heat dissipation and other faults. The cylinder will explode.
