1 minute to understand the car filter, car maintenance without stepping on the pit!

  In automotive maintenance, oil filters, air filters, air conditioning filters and fuel filters, collectively known as the four filters of the automobile, each play an indispensable role.

  The main function of the four filters is to filter impurities and provide a clean working environment for the lubrication system, air intake system, air conditioning system and fuel supply system.

  When faced with a wide range of choices when it comes to automobile maintenance, it is especially important to understand the detailed functions and replacement intervals of the four filters. Below, we will introduce the four filters one by one, to help you easily deal with the challenges of automotive maintenance.

1.oil filter 

Function: Filter out impurities in the lubricating oil to ensure the cleanliness of the oil.
