What is the optimal mileage interval for car maintenance?

Generally, it is best to perform car maintenance every 5,000 kilometers, as this can effectively extend the vehicle's service life. Typically, cars require maintenance every 5,000 kilometers, primarily referring to the lubrication system. Additionally, consumable parts of the vehicle should be replaced on schedule, such as brake pads, wiper blades, tires, belts, batteries, brake fluid, etc. Regular inspections of various electrical and oil systems are also necessary. Below is an introduction to car maintenance: 1. Car maintenance refers to the preventive work of regularly inspecting, cleaning, replenishing, lubricating, adjusting, or replacing certain parts of the vehicle, also known as vehicle upkeep. 2. Modern car maintenance mainly includes the engine system, transmission system, air conditioning system, cooling system, fuel system, power steering system, and other maintenance areas. 3. The purpose of car maintenance is to keep the vehicle clean and in good technical condition, eliminate potential hazards, prevent faults, slow down the deterioration process, and extend the usage cycle.

Having driven various cars for so many years, I've found that maintenance intervals are definitely not one-size-fits-all. Generally speaking, following the car manual's recommendations, most new cars are perfectly fine with minor maintenance every 8,000 to 10,000 kilometers - especially oil and filter changes are crucial. If you're doing lots of short city trips with frequent stop-and-go traffic and red lights, it might be safer to shorten it to 5,000 kilometers to prevent engine carbon buildup that could affect longevity. Don't forget to check tire wear and brake systems - in harsh environments like areas with lots of rain/snow or poor road conditions, wear happens faster. Be slightly more diligent during the first two years with a new car, then you can relax a bit after the break-in period. Following the manual and regular inspections can extend your car's lifespan, saving both hassle and money. Don't delay too long or small issues might turn into major problems.

When driving long distances on highways, I pay more attention to maintenance intervals. Based on personal experience, I go for a check-up every 5,000 to 8,000 kilometers. For someone like me who frequently drives on rural roads with heavy dust and constant vibrations, the oil quality deteriorates faster, and filters get clogged more easily. In rainy or humid environments, the risk of metal component corrosion is higher, so early inspections can prevent rust. During the break-in period of a new car, maintenance intervals should be shorter, starting at 5,000 kilometers. Older cars, on the other hand, can endure longer, with intervals around 7,500 kilometers being fine. Don’t just focus on mileage—consider driving habits too, such as frequent acceleration or heavy loads, which accelerate part wear. Regularly listen for unusual engine noises and monitor oil color changes to adjust flexibly and avoid sudden breakdowns, ensuring safety.

For new cars, it's advisable to maintain a higher frequency of maintenance, with oil changes every 5,000 kilometers to avoid engine break-in issues. For older vehicles, you can be more relaxed, extending intervals to 8,000–10,000 kilometers. The key is to regularly check the engine oil—take immediate action if it turns black or thickens. Don’t overlook replacing the air filter to prevent dust buildup. For city driving, shorten the intervals slightly, while highway or long-distance trips allow for delays. Always follow the car’s condition and the manual’s recommendations for the wisest approach, as maintaining steady vehicle performance is paramount.
