When is the first maintenance for a sedan?

[StVivienne]

New cars should undergo their first maintenance within 3 to 5 months, with the initial maintenance mileage typically ranging from 3,000 to 5,000 kilometers, whichever comes first. Below is relevant information about a car's first maintenance: 1. The primary tasks during a car's first maintenance involve changing the engine oil and oil filter. It's important to note that when replacing the engine oil, the oil filter must also be replaced simultaneously. Failure to replace the oil filter can result in the new oil being contaminated by the old filter. 2. Different car brands and models are equipped with various engines. Some engines utilize special technologies that impose strict requirements on the engine oil, while others are made from special materials with high precision, resulting in relatively less wear. Consequently, the stipulated time and mileage for the first maintenance vary.
