What items should be maintained for a car at 15,000 kilometers?

[VeraLynn]

For a car at 15,000 kilometers, the following maintenance items should be performed: 1. Replace the engine oil and oil filter; if the engine speed is unstable during idling or starting, a throttle cleaning can be added. Typically, the replacement cycle for the air filter is 20,000-30,000 kilometers, and for the fuel filter, it is 40,000-60,000 kilometers. 2. Air filter: The engine inhales a large amount of air during operation. If the air is not filtered, the dust in it can accelerate the wear of the piston group and cylinder. Larger particles entering between the piston and cylinder can also cause severe "cylinder scoring." The function of the air filter is to remove dust and particles from the air, ensuring that sufficient and clean air enters the cylinder. 3. Fuel filter: The fuel filter provides clean fuel to the engine by filtering out water and impurities from the gasoline. This optimizes engine performance and provides the best protection for the engine.
