How Many Kilometers for the First Maintenance of a Sedan?
1 Answers
New cars require their first maintenance at 5,000 kilometers. Regular preventive maintenance on certain parts of the vehicle aims to keep the car clean, ensure normal technical conditions, eliminate hidden dangers, prevent faults, slow down the deterioration process, and extend the service life. Maintenance items include the following two aspects: 1. Minor Maintenance; (1) Engine Oil Change: Lubricates, cleans, cools, seals, and reduces friction in the engine, thereby decreasing wear on engine components; (2) Oil Filter Replacement: Engine oil contains a certain amount of gum, impurities, moisture, and additives. During engine operation, metal shavings from friction, airborne impurities, and oil oxidation products are all filtered by the oil filter. If the oil is not filtered and directly enters the oil circulation, it will adversely affect the engine's performance and lifespan; 2. Major Maintenance; (1) Air Filter: The engine inhales a large amount of air during operation. If the air is not filtered, the dust in it can accelerate wear on the piston group and cylinder. Larger particles entering between the piston and cylinder can also cause severe "cylinder scoring." The air filter's role is to remove dust and particles from the air, ensuring sufficient and clean air enters the cylinder; (2) Fuel Filter: The fuel filter's function is to provide clean fuel to the engine, filtering out moisture and impurities in the gasoline, thereby optimizing engine performance and providing the best protection for the engine.
