Can car maintenance be done outside a 4S shop?

[IsabelaDella]

Car maintenance can indeed be performed outside a 4S shop. The maintenance items for a car include core components and wear-and-tear parts. Core components consist of the chassis, engine, and transmission, while wear-and-tear parts include engine oil and oil filter, spark plugs, air conditioning filters, tires, brakes, and car lights. The replacement intervals for car maintenance parts are as follows: 1. Brake pads should be replaced every 50,000 kilometers; 2. Spark plugs should be replaced every 20,000 kilometers; 3. Engine oil and oil filter should be replaced every 5,000 kilometers; 4. Air conditioning filters should be replaced every 20,000 to 30,000 kilometers.
