What items are included in a 20,000-kilometer car maintenance?

A 20,000-kilometer maintenance is typically the third service for a car and is generally considered a major maintenance. The routine items for the third car maintenance include changing the engine oil, oil filter, air filter, cabin air filter, spark plugs, etc. Some brand manufacturers may add additional maintenance items. More detailed descriptions are as follows: 1. Changing the engine oil and oil filter is a mandatory item. Due to the harsh high-temperature and high-pressure environment inside the engine, the shelf life of the engine oil is significantly shortened, and its performance greatly declines. Over time, it fails to protect the engine. The oil filter prevents impurities from mixing into the oil, causing oxidation and producing sludge that can clog the oil passages. The engine oil and oil filter are always replaced simultaneously. 2. Secondly, the air filter also needs to be replaced by this time. If it wasn't replaced during the 10,000-kilometer maintenance, it must be replaced during the 20,000-kilometer maintenance. The air filter's function 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 can lead to dust being sucked into the engine, causing abnormal wear on the cylinder walls. 3. Additionally, if the car uses standard material spark plugs, preparations should be made to replace them at the 20,000-kilometer mark. Spark plugs directly affect the engine's acceleration performance and fuel consumption. When you feel a lack of engine power while driving, maintenance should be performed. The service life of spark plugs varies depending on their material.
