New cars require at 5,000 kilometers. Vehicles need maintenance after reaching certain mileage intervals. Car maintenance refers to the preventive work of regularly inspecting, cleaning, supplying, lubricating, adjusting, or replacing certain parts of a car, also known as car servicing. Modern car maintenance mainly includes the engine system, transmission system, air conditioning system, cooling system, fuel system, power steering system, etc. The purpose of car maintenance is to keep the vehicle clean, maintain normal technical conditions, eliminate hidden dangers, prevent faults, slow down the deterioration process, and extend the service life.

Don't just focus on driving your new car - the first service is particularly crucial. My neighbor's Japanese car had its first service at 5,000 kilometers, where they changed the free engine oil and oil filter. The 4S店 technician specifically reminded that new cars now come with factory-installed break-in oil, which needs to be replaced between 3,000-5,000 kilometers. I remember my German car's manual stated the first service at 10,000 kilometers, but a mechanic secretly told me to go in by 8,000 kilometers because metal particles during the break-in period can contaminate the oil. The differences between brands are significant - most American cars recommend maintenance at 8,000 kilometers. Actually, the most accurate way is to follow the dashboard alerts, as new cars now have smart maintenance reminder functions. The key is not to exceed the first service interval, otherwise it may affect the warranty.

When I first got the car, I was also confused and asked Old Zhang from the repair shop. He said the first for a new car is like a baby's one-month celebration. Full synthetic oil can last up to 10,000 kilometers, while mineral oil starts to degrade significantly after 5,000 kilometers. The key is to check the brake pad break-in condition, especially in the first three months of a new car. Once before a long trip, I checked and found the tire pressure was off by 0.5 bar. He suggested checking fluids frequently in the first six months, especially for cars often driven on rough roads. In dusty areas, the air filter should be replaced every 3,000 kilometers. Always get the maintenance dates stamped in the record book, as it's crucial for resale value.

As a mechanic with ten years of experience, I recommend doing the first ahead of schedule. I've seen too many cars that waited until the full mileage, with oil pans full of metal shavings. It depends on the oil type: full synthetic must be changed within 10,000 km, semi-synthetic within 7,500 km, and mineral oil should not exceed 5,000 km. For the first three months of a new car, focus on checking the chassis bolts. I had a customer whose new car's steering ball joint loosened after just 2,000 km. Also inspect the brake fluid lines—last year, an SUV leaked brake fluid after only 4,000 km. Don't blindly trust smart reminder systems; things like uneven tire wear can't be detected by computers.

We female car owners pay more attention to details. I remember the first maintenance of my Toyota was at 8,000 kilometers, and the 4S shop offered a windshield washer fluid top-up service. The maintenance manual clearly states that hybrid car maintenance requires checking the battery vent, which many owners overlook. Last time, my best friend's electric car went for maintenance at 3,000 kilometers, and the technician found oxidation and poor contact at the charging port. It's recommended that new owners use their phones to record each maintenance item, especially keeping an eye on replacing the cabin air filter. With a lot of pollen in spring, I basically change the filter every three months, as the six-month cycle suggested in the manual is too long.

Veteran drivers know to adjust based on driving conditions. For regular commuters, 10,000 km intervals are fine. But like me, frequently driving to construction sites—my new car hit 5,000 km in three months for an oil change, with the oil turning chocolate-colored. The mechanic said prolonged low-speed driving easily causes sludge buildup; for frequent short trips, change oil at 7,000 km. Last time helping my son shop for a new car, I discovered a great feature: the center display shows remaining oil life percentage—prepare for maintenance when below 80%. Don’t wait until 10,000 km for tire rotation; swapping front/rear at 7,000 km reduces uneven wear. Northern drivers, remember to check antifreeze freeze point before winter.
