What is generally replaced during a car's first maintenance?

The key items for a car's first maintenance are changing the engine oil and oil filter. Additionally, a full vehicle system inspection will be conducted, such as tightening nuts, checking the chassis, tire inspection, and system computer diagnostics. The first maintenance service is relatively simple and can usually be completed in about half an hour to an hour. Since the period before the first maintenance is the vehicle's break-in period, the gradually breaking-in engine will continuously mix mechanical impurities like dust, metal wear, and carbon deposits into the engine oil during operation. Therefore, changing the engine oil and oil filter during the first maintenance is crucial. If the debris and impurities generated by the engine operation are not promptly removed, it may cause abnormal damage to the internal parts of the cylinders.
Last time when I accompanied my best friend for the first maintenance, the technician said there are three essential items to replace: engine oil and oil filter are standard, as metal debris may mix into the oil during the break-in period of a new car. The cabin air filter is replaced based on condition, but the 4S shop usually changes it for free. They also checked the tire pressure and brake pad thickness. The mechanic used a flashlight to inspect the chassis bolts, mentioning that they might loosen after the first 1,000 kilometers on a new car. An extra fun fact—some cars require transmission fluid change during the first service, especially performance models. Remember to bring the maintenance manual, or you might get charged! Don’t miss the free first service deadline—exceeding the mileage or time limit would be a huge loss.
