Generally, the second maintenance for a car is performed when the vehicle has been driven for 10,000 kilometers or between 9 months to a year, which means it is spaced 5,000 kilometers or 3 months to half a year after the first maintenance. However, some models have their first maintenance at 8,000 kilometers or 10,000 kilometers, in which case the second maintenance will be correspondingly delayed. Relevant details about the second maintenance are as follows: 1. Items for the second maintenance: It includes inspection and maintenance of 63 items across eight major systems—engine, transmission, braking system, steering system, air conditioning system, body system, tire system, and suspension system—along with quality inspection and test driving. The key tasks, similar to the first maintenance, involve changing the engine oil and oil filter. 2. Replacements needed during the second maintenance: The air filter and cabin air filter also need to be replaced during the second maintenance. These parts can be replaced at the 4S shop, or you can purchase matching parts online and replace them yourself, which can save some costs.

The second maintenance is generally most suitable around 10,000 kilometers. My car had it done at 9,000 kilometers last time. It ultimately depends on your vehicle manual's recommendations—for example, German cars might require it at 15,000 km, while Japanese cars often suggest 10,000 km. If you drive in harsh conditions, such as frequently on dusty rural roads or in congested urban traffic, advancing it to 8,000 km is better. The second maintenance mainly involves basic items like changing the engine oil and oil filter, checking brakes and tires, ensuring engine lubrication to prevent wear. Neglecting it may lead to increased fuel consumption or component damage, and delayed oil changes can cause carbon buildup. I always book an appointment with the dealership in advance for each service—costing a few hundred yuan—which offers good value for money, extends the car's lifespan, and provides peace of mind for daily commuting.

I usually commute and shuttle my kids, and the second maintenance for our family car was done at 9,500 kilometers. The vehicle manual typically recommends a 10,000-kilometer interval, starting after the first maintenance at 5,000 kilometers. The second maintenance isn't just about changing the oil; the technician also checks the braking system, cabin air filter, and electronic devices to prevent sudden malfunctions. If you frequently drive short distances or on highways, the mileage can be slightly adjusted. For example, since I drive short distances daily to drop off my kids, the oil quality deteriorates more easily, so doing it a bit earlier is safer. Remember, timely maintenance can save a lot on fuel costs, keeps the engine running smoothly, and ensures safety—especially important when you have elderly and children on board for peace of mind.

The mileage for the second maintenance depends on the vehicle model, mostly around 10,000 km. Based on my experience, if the manual specifies 10,000 km, perform the second maintenance on time, including oil changes and inspections. This saves fuel and maintains engine health. Don't delay to avoid expensive repairs later.
