After a new car is driven off the lot, the 4S shop generally requires the owner to perform the first within 3,000 kilometers. Here are some details about the first maintenance of a car: 1. The period from when a new car is driven until the first maintenance is called the break-in period. 2. During the break-in period, because the gears of the engine, transmission, etc. have not yet fully broken in smoothly, the driver generally should not drive too fast, preferably not exceeding 80 km/h. 3. During the break-in period, in addition to not exceeding 80 km/h, the engine speed should also not exceed 3,000 rpm, and acceleration should not be too harsh, otherwise it will not be good for the engine's break-in.

The first of a new car should not be approached with a one-size-fits-all mentality. My German car requires its first service at 10,000 kilometers, but a friend who drives a Japanese car mentioned needing to go in at 7,500 kilometers. Most first maintenance intervals fall between 5,000 to 10,000 kilometers—the key is to check the owner's manual. First maintenance isn't just about changing the oil and filter; dealerships also inspect hidden items like the tightness of all screws, undercarriage damage, and battery condition. From my experience, it's best not to exceed 10,000 kilometers, especially for those frequently stuck in traffic, as engine carbon buildup occurs earlier than in cars that mostly drive on highways. Missing the first maintenance period might affect the warranty, so this is something to be particularly cautious about.

When I first got the car, I kept a close eye on the odometer every day, afraid of missing the first . The salesperson told me maintenance could be done within 8,000 km, but when I checked the manual, it said '6 months or 7,500 km'—shorter than what I was told. Doing the first maintenance a bit earlier isn't a bad idea, as there are metal shavings in the new engine, and replacing the break-in oil early is good for the car. Hybrid models require even more attention—while the electric motor doesn’t burn oil, the reducer oil needs to be changed. My friend’s car had transmission issues because she exceeded the first maintenance by 2,000 km, and the dealership almost refused to cover the repair.

Nowadays, the interval for the first is getting longer. The manual for my American SUV directly requires the first service at 12,000 kilometers, but the 4S shop recommends going at 8,000. There's a catch here: vehicles using full synthetic oil can extend the interval appropriately, but those with turbochargers must go on time. Avoid aggressive driving during the break-in period of a new car, and keep the RPM below 4,000 for the first 3,000 kilometers. For plug-in hybrids, pay attention to the engine's first start time; even if the mileage isn't reached, the oil should be changed after 6 months.

Last time I accompanied my buddy for his first at only 6,000 km, the technician said it was a huge loss. Turns out he drove straight to National Highway 318 with his brand-new car, where the high-altitude road conditions accelerated oil degradation. In cold regions, maintenance should be done even earlier, as engine oil fluidity worsens at -30°C. Pure electric vehicles are more worry-free—their first maintenance just involves checking brake fluid and AC filters, which can wait until 20,000 km. Remember to bring the warranty certificate for the first service, as some shops push paid add-ons like undercoating, which are completely unnecessary.

Noticed a pattern: the more expensive the car, the longer the first service interval. My friend's had its first service at 15,000 km, while domestic cars mostly require it at 5,000 km. But don't be misled—the core purpose of the first service is to drain the initial factory oil containing metal particles. I prefer taking a highway drive at 3,000 km to promote engine break-in and then heading to the shop right at 5,000 km. For full-time 4WD vehicles, pay attention to the differential oil replacement schedule, which comes earlier than for 2WD cars. For cars with start-stop systems, remind the technician to check the dedicated battery. Actually, you can check the maintenance schedule on the manufacturer's app—it's more convenient than flipping through the manual if you're feeling lazy.
