What does the oil filter refer to? How often is the filter core replaced?

Three oil filters refer to gasoline filters, oil filters and air filters. Gasoline filter is called steam filter for short, and its main function is to filter out impurities in gasoline. If the gasoline filter is too dirty or blocked, it will slow or fail to start when filling the fuel door, making it difficult for the vehicle to start, and sometimes it may take several times to fire. The gasoline filter should be changed every 40,000 kilometers.

Oil filter, also known as oil grid, is mainly used to remove impurities such as dust, metal particles, carbon deposits and soot particles from oil, thus protecting the engine. Oil filters have higher requirements for filter paper. As the temperature of the oil varies from 0 to 300 degrees, the concentration of the oil changes correspondingly under the drastic temperature change, which will affect the filtration flow of the oil. The filter paper of high-quality oil filter should be able to filter impurities under severe temperature changes, while ensuring sufficient flow. The oil filter is determined according to the oil change cycle, and a new oil filter should be replaced every time the oil is changed.

Air filters, also called air filter cartridges and styles, are mainly used for air filtration in engineering cars, automobiles, agricultural locomotives and various precision operation rooms. When the engine is working, it needs to suck in a lot of air. If the air is not filtered, the dust in the air will be sucked into the cylinder, which will accelerate the wear of the piston group and the cylinder. If larger particles enter the piston and cylinder, it may cause serious cylinder pulling phenomenon, so the air filter is particularly important.

There is no fixed replacement cycle for the air filter, but most car owners will choose to replace it once a year or every 20,000 kilometers, and check the usage of the air filter every six months. If car owners often drive in dusty places such as construction sites and wooden factories, they may need to be replaced after driving for half a year.
