What Needs to Be Replaced in a 20,000 km Maintenance?
1 Answers
For a 20,000 km car maintenance, it is necessary to replace the engine oil, oil filter, air filter, cabin air filter, and spark plugs, among other items. Here are the specific details: 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 deteriorates substantially. 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 the formation of sludge and clogging the oil passages. The engine oil and oil filter should be replaced simultaneously. 2. The air filter's role is to block dust and particles from being sucked into the engine during the intake process. If the filter is not cleaned for a long time, dust can enter the engine, causing abnormal wear on the cylinder walls. If the air filter was not replaced during the 10,000 km maintenance, it must be replaced at the 20,000 km maintenance. 3. If the car uses standard material spark plugs, they should also be prepared for replacement at 20,000 km. Spark plugs directly affect the engine's acceleration performance and fuel consumption. If you feel a lack of engine power while driving, it's time for maintenance.
