What should be replaced during the second maintenance of a new car?

Maintenance items include inspection and maintenance of dozens of components such as the engine, transmission, air conditioning system, steering system, braking system, suspension, body, and tire system. The key items remain oil change and oil filter replacement. Below are the details regarding oil change and oil filter replacement: 1. Oil change: For the second maintenance, the same oil used during the first maintenance can be continued. If desired, a higher-quality oil can be used. Naturally aspirated engines can upgrade to semi-synthetic oil, while fully synthetic oil is unnecessary. Turbocharged engines have relatively higher requirements for oil quality, so semi-synthetic or fully synthetic oil should be used, preferably fully synthetic oil. 2. Oil filter replacement: Its function is to filter out harmful impurities from the oil in the oil pan, providing clean oil to moving components such as the crankshaft, connecting rod, camshaft, turbocharger, and piston rings, serving the purposes of lubrication, cooling, and cleaning, thereby extending the lifespan of these parts.
As a novice taking my car for its second maintenance for the first time, I learned a lot. The main tasks included changing the engine oil and oil filter, as the oil turns black and becomes ineffective after thousands of kilometers—replacing it keeps the engine lubricated. The air filter also needs replacement because dust buildup in the intake affects performance. The cabin air filter was checked and replaced if dirty to ensure air quality. Tires were rotated to ensure even wear and extend their lifespan. Brake fluid and coolant levels were inspected for safety. The lighting system was also checked for any issues. The entire maintenance process took about an hour at a reasonable cost. Never delay maintenance—it protects the engine, reduces faults, and keeps the car running smoothly. After experiencing it myself, I feel more confident driving. Next time, I plan to ask the mechanic for more maintenance tips.
