How Many Kilometers for the First Maintenance of a Sedan?
4 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.
I've been driving for many years. The first maintenance for a new car is usually around 5,000 kilometers, mainly to change the engine oil and filters, because the initial run of a new engine produces metal debris. If not removed in time, it can lead to increased wear and affect the lifespan. I remember when I bought my first car, a friend suggested doing it between 3,000-5,000 kilometers, but I delayed until 6,000 kilometers. Later, the fuel consumption increased significantly. Actually, the manufacturer's manual is key. For example, my Toyota is at 5,000 kilometers, while my friend's BMW is at 7,000. So don't guess, check the manual for the most accurate information. During maintenance, also check the brakes and tires to ensure safety, and to avoid voiding the warranty, which could lead to expensive repairs later.
When I first got my driver's license and bought a new car, I didn't know when the first maintenance should be done. The mechanic told me that usually the first oil and filter change is done at 5,000 kilometers. It's important to clean out impurities after the new engine breaks in, which takes about 1,000-3,000 kilometers. I went on schedule, and it didn't cost much but made a noticeable difference—the car ran much smoother. I recommend that beginners don't skip this expense. Check the vehicle manual to confirm because it may vary by model. For example, most domestic cars are at 5,000 kilometers, while imported cars might be slightly higher. Regular maintenance extends the car's lifespan and saves on major repair costs.
The recommended mileage for the first maintenance of a sedan is around 5,000 kilometers for an oil change to protect the engine and prevent early damage. The actual operation is simple and takes little time. Do not exceed the manual's specifications. My experience is that 5,000 kilometers is just right—the car runs more smoothly, and it also allows for checking tire pressure and brakes to ensure driving safety. Neglecting it may lead to performance degradation and increased fuel consumption. There's no harm in following the manufacturer's recommendations.
