What are the main items for car maintenance?

Car maintenance mainly involves replacing the three filters and engine oil, as well as inspecting the vehicle's electrical system, tires, and braking system. The functions of the three filters and engine oil are as follows: 1. Oil filter: It filters out impurities, metal shavings, and sludge carried by the engine oil inside the engine. 2. Cabin air filter: It filters out solid impurities such as dust, pollen, and abrasive particles in the air, as well as moisture and harmful gases. 3. Air filter: The engine needs to intake a large amount of air during operation. If the air is not filtered, the suspended dust particles in the air can be sucked into the cylinders, accelerating the wear of the piston group and cylinders. 4. Engine oil: Engine oil lubricates the engine, reduces internal wear, aids in cooling, prevents rust and corrosion, and cleans the engine.
