What maintenance items should be performed at 20,000 kilometers for a car?

[ZoeyLee]

The maintenance items to be performed at 20,000 kilometers for a car include changing the engine oil, oil filter, air filter, cabin air filter, spark plugs, etc. The function of the air filter is to block dust and particles inhaled by the engine during the intake process. If the filter is not cleaned for a long time, it will cause the engine to inhale dust, resulting in abnormal wear of the cylinder walls. If it was not replaced during the 10,000-kilometer maintenance, it must be replaced at the 20,000-kilometer maintenance. If the car uses ordinary material spark plugs, then preparations should also be made to replace them at 20,000 kilometers. Spark plugs directly affect the engine's acceleration performance and fuel consumption. When you feel the engine's power is insufficient while driving, maintenance should be performed.
