What items are required for a 20,000-kilometer car maintenance?
1 Answers
Car maintenance items required at 20,000 kilometers are as follows: 1. Engine oil and oil filter: The maintenance of engine oil and oil filter is something almost everyone knows, as these are nearly mandatory items for every maintenance session. Engine oil generally serves functions such as lubrication, cooling, and rust prevention. Over time, its quality deteriorates, which can increase engine wear. The oil filter is primarily used to filter out impurities in the oil. Not replacing it for a long time can lead to a decline in filtration performance, thereby reducing the engine's lifespan. Therefore, replacing the engine oil and oil filter is almost an essential part of every car's maintenance. 2. Air filter: The air filter is a maintenance item that many car owners often overlook, thinking it has little effect and that replacement is optional. However, this is incorrect. The air filter acts like a human respiratory filtration system. If it becomes too dirty, foreign particles can enter the combustion chamber, increasing engine wear. Its replacement cycle is generally around 7,500–10,000 km. Additionally, using a high-pressure air gun to clean the air filter is not recommended because the filter relies on surface fibers to trap dust and other particles, and the high-pressure air gun can damage these fibers, reducing its filtration efficiency.
