What does the oil filter mean?How often to replace the three filters and one filter

The three oil filters refer to the gasoline filter, the oil filter and the air filter. The gasoline filter is referred to as the steam filter, and its main function is to filter out the impurities in the gasoline. If the gasoline filter is too dirty or clogged, the power will be slow or unable to come up when the throttle is applied, and the vehicle will be difficult to start. Sometimes it may take a few times to fire. The gasoline filter needs to be replaced every 40,000 kilometers.

The oil filter, also known as the oil grid, is mainly used to remove impurities such as dust, metal particles, carbon deposits and soot particles in the oil to protect the engine. The oil filter has relatively high requirements for filter paper. Since the temperature of the oil varies from 0 to 300 degrees, the concentration of the oil also changes correspondingly under the severe temperature change, which will affect the filtration flow of the oil. The filter paper of a 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 replacement cycle, and a new oil filter must be replaced every time the oil is changed.

Air filter, also known as air filter cartridge, style, etc., is mainly used for air filtration in engineering vehicles, automobiles, agricultural locomotives and various precision operating rooms. The engine needs to suck in a lot of air when it is working. 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 relatively large particles enter the piston and cylinder, it may also cause a more 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 after driving 20,000 kilometers, and check the use of the air filter every six months. If the owner often drives in dusty places such as construction sites and wooden factories, it may need to be replaced after driving for half a year.
