[Lorraine]

The basic maintenance provided by 4S stores mainly includes the replacement of components such as engine oil and oil filter, air filter, gasoline filter, and pollen filter, as well as the maintenance or replacement of spark plugs, and system inspection and maintenance related to transmission oil, brake fluid, battery, throttle, fuel injector, brake pads, etc. Below are some descriptions of the maintenance items: 1. Engine oil and oil filter: Primarily for the maintenance of the lubrication system. The main function of the lubrication system is to effectively lubricate various components of the car engine to prevent excessive wear. The oil filter's function is to remove various impurities from the engine oil, ensuring the normal operation of the lubrication system. The oil filter should be replaced along with the engine oil during an oil change. 2. Air filter: The air filter's role is to filter the air before it enters the cylinder, removing impurities, dust, sand, and other foreign particles. The cleaning and maintenance of the air filter depend on the usage environment. The gasoline filter is generally replaced after driving 20,000-25,000 km. 3. Spark plug: The spark plug is a consumable part and should be replaced every 20,000 km.
