The third maintenance for a new car should be done after running 20,000 to 25,000 kilometers. Below is relevant information about new car maintenance: 1. Maintenance intervals: The first maintenance for a car is around 3,000-7,500 kilometers; the second maintenance is around 10,000-15,000 kilometers; the third maintenance is around 20,000-25,000 kilometers. 2. Maintenance items: Car maintenance items include core components and wear-prone parts. Core components include the chassis, engine, and transmission, while wear-prone parts include engine oil and oil filter, spark plugs, air conditioning filter, tires, brakes, lights, etc.

I've been driving for over a decade. The third maintenance for a new car usually occurs around 20,000 to 30,000 kilometers, depending on what car you drive. For example, my SUV's manual states the first service at 5,000 km, the second at 15,000 km, and the third around 25,000 km. However, don't just focus on mileage—timing is crucial too. A friend of mine neglected the time factor and only drove 10,000 km but went six months without maintenance, which led to chassis issues. The third maintenance typically involves changing the engine oil, replacing the air filter, and inspecting the brake system. These items significantly impact vehicle performance, and long-term neglect can shorten engine lifespan. Therefore, it's good practice to keep maintenance records while driving and schedule regular appointments with the 4S shop.

As an enthusiast who enjoys studying cars, the mileage for the third maintenance of a new car actually depends on the brand. For example, German cars might be in the range of 18,000 to 28,000 kilometers, while Japanese cars tend to be slightly higher, around 22,000 to 32,000 kilometers. Since I drive frequently, I recommend adjusting based on actual driving conditions: if there's a lot of city traffic, consider an early check at 15,000 kilometers; if you drive more on highways, you can delay it to 30,000 kilometers. Key items for this maintenance include engine oil, oil filter, and tire balancing. Don't skip these to save trouble, or you might face increased fuel consumption, unstable steering, and compromised daily driving safety. Remember to refer to the owner's manual for regular tracking to avoid unexpected damage.

As an office worker myself, the third maintenance for a new car is usually around 20,000 to 25,000 kilometers. For my sedan, the first maintenance was at 5,000 km, the second at 15,000 km, and the third will be over 20,000 km. It's important to be flexible with long or short trips: delay a bit more if you drive a lot on highways, but don't exceed the upper limit of 30,000 km. The main maintenance items include basic upkeep like oil and filter changes. Developing a habit of recording mileage is crucial for timely repairs.
