Within how many kilometers is the second maintenance for a new car generally required?

The second maintenance for a new car is typically required after the car has been driven for 10,000 kilometers or around one year, which means it is spaced 5,000 kilometers or six months apart from the first maintenance. Of course, for some car models, the first maintenance is due at 8,000 kilometers or 10,000 kilometers, in which case the second maintenance will also be delayed accordingly. After the second maintenance, the performance of the new car will be basically stable, and subsequent maintenance is usually performed every 10,000 to 15,000 kilometers. The second maintenance for a new car is very important. The maintenance items involve inspection and maintenance of dozens of components across multiple systems, including the engine, transmission, air conditioning system, steering system, braking system, suspension, body, and tires. The key items are changing the engine oil and oil filter. Additionally, during the second maintenance, both the air filter and cabin air filter need to be replaced. In fact, these two parts can be replaced by yourself—simply purchase the parts online and replace them manually. Notes for the second maintenance: For the second maintenance of a car, there is no need for other replacements or cleaning, such as engine cleaning. Just stick to these maintenance items. Other checks, such as coolant, brake fluid, and tire pressure, are usually free of charge. Before the second maintenance, make sure to carefully review the maintenance checklist and avoid unnecessary items.
