Generally, a car should undergo maintenance every 5,000 kilometers or approximately every six months. 4S shops typically recommend maintenance intervals ranging from 5,000 to 10,000 kilometers. For new cars, the first maintenance is usually required after three months or 3,000 kilometers. During the initial break-in period of a new car, many components need to be properly run in. Therefore, the oil filter should be replaced at 3,000 kilometers, and the engine oil, oil filter, and air filter should be replaced at 7,500 kilometers. After the break-in period, maintenance should be performed every 5,000 kilometers. It is also important to choose an authorized 4S shop for maintenance. The primary purpose of car maintenance is to keep the vehicle clean and in good technical condition, which helps eliminate potential safety hazards, prevent accidents, slow down the aging process of components, extend their service life, and ensure the car operates properly. Routine maintenance items include replacing the engine oil and oil filter; cleaning the air filter; inspecting spark plugs, brake fluid, transmission fluid, battery, throttle body, and fuel injectors; checking tires and their pressure; and examining the chassis components such as brake pads, brake discs, brake lines, steering linkage ball joints, and shock absorbers.

Last time, my neighbor Lao Wang mentioned this while changing his oil. Most regular gasoline cars are recommended for maintenance every 5,000 to 8,000 kilometers, but it's not a one-size-fits-all situation. My Japanese car's manual suggests maintenance every 10,000 kilometers, but my buddy who's always on construction sites needs it every three months. The key is to monitor the oil life—for those often stuck in traffic with frequent engine start-stop cycles, it's wise to check 1,000 kilometers early. Turbocharged cars require even more frequent maintenance, especially those using full synthetic oil. While they might last up to 8,000 kilometers, an early check never hurts. Remember, over-maintenance can also hit your wallet hard!

Having run an auto repair shop for over a decade, I've seen countless cases. German cars generally have longer maintenance intervals - my BMW manual specifies service every 12,000 km, but in reality the engine oil turns black by 7,000-8,000 km. Japanese cars recommend shorter intervals; Fit owners should ideally get inspections every 5,000 km. Hybrid owners take note: while electric motors require no maintenance, the combustion engine's service schedule must follow the manual strictly. Northern drivers should pay special attention - frequent short trips in winter can cause oil emulsification, suggesting a 20% reduction in maintenance mileage. Always check air filters during each service, and in dusty regions, reduce maintenance intervals by 20%.

Those who are into car modifications know that maintenance is like extending its life. A stock car can go up to 8,000 km, but a car with a tuned ECU requires earlier maintenance—my Civic gets a full synthetic oil change every 4,000 km without fail. If you've modified the suspension, inspect the chassis components more frequently, especially if the car is lowered, as bushings wear out about 30% faster. For those who participate in track days, it's not excessive to perform maintenance immediately after a session. If you've just bought a used car, don't delay the first maintenance—change the engine oil and transmission fluid right away. For older cars, the maintenance interval should be shortened by another 15%, as rubber components really can't afford to be neglected!
