What are the maintenance items for a vehicle at 20,000 kilometers?

[VanLucas]

At the 20,000-kilometer maintenance, the engine oil, oil filter, air filter, and cabin air filter should be replaced, along with some routine inspections. The details are as follows: 1. Air filter: Proper installation of the air filter can reduce wear on components such as cylinders, pistons, and piston rings. Generally, it should be cleaned every 5,000 kilometers and replaced every 10,000 kilometers. 2. Oil filter: Proper installation of the oil filter prevents impurities from mixing into the engine oil during use, avoiding wear on moving parts and oil passage blockages. When changing the lubricating oil, the oil filter must also be replaced; otherwise, it may affect the quality of the lubricating oil. The replacement cycle for engine oil and the oil filter is typically every 5,000 kilometers. 3. Fuel filter: Proper installation of the fuel filter prevents cylinder wear caused by impurities and moisture mixed into the gasoline during storage, transportation, and refueling. To ensure optimal engine performance, the fuel filter should generally be replaced every 20,000 kilometers or once a year.
