What maintenance is required for a sedan at 20,000 kilometers?

Generally, the 20,000-kilometer maintenance for a car is considered a major service, typically the third maintenance session. Routine items include changing the engine oil, oil filter, air filter, cabin air filter, and spark plugs. Below is a detailed explanation: 1. Replacing the engine oil and oil filter is essential. Under the harsh conditions of high temperature and high pressure inside the engine, the shelf life of engine oil is significantly shortened, and its performance degrades considerably. Over time, it fails to protect the engine effectively. The oil filter prevents impurities from mixing with the oil, which can cause oxidation, leading to sludge and clogging the oil passages. Both the engine oil and oil filter should be replaced simultaneously. 2. The air filter's role is to block dust and particles that the engine might inhale during the intake process. If the filter is not cleaned regularly, it can lead to dust entering the engine, causing abnormal wear on the cylinder walls. If it wasn't replaced during the 10,000-kilometer maintenance, it must be replaced at the 20,000-kilometer service. 3. If the car uses standard material spark plugs, preparations should be made to replace them at 20,000 kilometers. Spark plugs directly affect the engine's acceleration performance and fuel efficiency. If you notice a lack of engine power while driving, it's time for maintenance. The lifespan of spark plugs varies depending on the material used.
