Is there any harm if a car exceeds the maintenance mileage?

[Gianna]

Whether exceeding the maintenance mileage is harmful depends on the kilometers: 1. Exceeding by about 500 kilometers is not very harmful; 2. Exceeding by 1,000 kilometers is more harmful. Car maintenance refers to the preventive work of regularly inspecting, cleaning, supplying, lubricating, adjusting, or replacing certain parts of the car. The regular maintenance items include replacing the oil filter, air filter, gasoline filter, and engine oil. The purpose of car maintenance is to filter impurities in the engine oil and gasoline to prevent them from entering the engine and affecting its normal operation. Regularly replacing these parts can effectively extend the engine's service life, keep the car clean, maintain normal technical conditions, eliminate hidden dangers, prevent faults, and slow down the deterioration process.
