Car maintenance refers to the preventive work of regularly inspecting, cleaning, replenishing, lubricating, adjusting, or replacing certain parts of a car, also known as car servicing. If the car is under warranty, maintenance must be done at a 4S shop. Relevant details are as follows: Advantages of 4S shops: 4S shops representing the manufacturer are responsible for the maintenance and repair of the vehicle during the warranty period. The engine oil, gear oil, and other lubricants used for maintenance at 4S shops are specified by the manufacturer. The parts used are original factory-installed components, whose performance is unmatched by other parts. All parameters meet the requirements of the vehicle, ensuring the longest service life, optimal economy, best handling, and highest safety. If maintenance is done elsewhere, without the manufacturer-provided lubricants and parts, the quality of maintenance cannot be guaranteed. If issues arise due to lubricants, parts, or other factors during the warranty period, the manufacturer will not be responsible. Therefore, maintenance during the car's warranty period must be done at a 4S shop representing the manufacturer. Maintenance items: Typically, during car maintenance, technicians will perform additional checks based on the specific condition of the vehicle, such as inspection, cleaning, and maintenance of the engine-related systems, tire alignment checks, inspection of various fastening components, etc. The fuel filter is an essential part. The function of the fuel filter is to provide clean fuel to the engine, filtering out water and impurities from the gasoline. This optimizes engine performance and provides the best protection for the engine.

I used to believe that going to the 4S shop was a must, but later I realized it's really not necessary. As a veteran driver with ten years of experience, I now go to the auto repair shop near my home. Master Li's shop has been open for twenty years, and changing the engine oil and filter is half the price of a 4S shop, with no compromise on quality. The key is that they don't push unnecessary cleaning services—they just follow the maintenance manual, and my car has been running perfectly without any issues. For new cars still under warranty, I still recommend going to the 4S shop to avoid disputes. But once the warranty period is over, you're free to choose a reputable repair shop, which can save you a lot of money. Nowadays, many chain quick-service shops offer professional services, and their records can be uploaded to the cloud, so there's nothing to worry about.

For the first two years after buying my car, I always took it to the 4S dealership for maintenance, just for peace of mind. They have the manufacturer's complete set of testing equipment and even give the whole car a check-up each time, adjusting things like tire pressure with precision. But honestly, every bill was painful—minor maintenance starts at 800, and replacing spark plugs costs over a thousand. Later, a friend recommended an independent repair shop specializing in my car brand, equipped with original diagnostic tools and using genuine parts at just 70% of the dealership's price. Especially for things like wiper blades and cabin air filters, I could buy genuine parts online and pay just 50 for labor. As long as it doesn't involve core components like the engine or transmission, going outside is really cost-effective.

The choice of maintenance location depends entirely on personal preference. My childhood friend works as an after-sales supervisor at a 4S shop, and he said they dread customers who don’t visit for two years. For services like tire and wheel maintenance, brand specialty shops are more professional and cheaper. However, transmission fluid changes must be done at a 4S shop because they have the original factory circulation equipment. Last month, my car’s battery died, and a technician from Tuhu arrived to replace it within half an hour after I placed an order. Nowadays, many apps allow you to check complete maintenance records, so there’s no need to worry about affecting the resale value. The key is to keep the repair receipts and parts invoices to prove that qualified products were used.
