How often should a major car maintenance be performed?

Major car maintenance is typically performed every three years or 60,000 kilometers. The main components of a major car maintenance include: 1. Oil change. An oil change is a mandatory part of major maintenance. Engine oil lubricates and reduces friction, aids in cooling, seals against leaks, prevents rust and corrosion, and provides shock absorption. 2. Oil filter replacement. The oil filter is replaced at the same time as the oil. The oil filter removes debris, sludge, and moisture from the oil, delivering clean oil to the lubrication points. 3. Air filter replacement. The air filter prevents dust and particles from being drawn into the engine during the intake process. If the filter is not cleaned regularly, dust can enter the engine, causing abnormal wear on the cylinder walls. 4. Cabin air filter replacement. If the cabin air filter is not cleaned or replaced for a long time, the car's air conditioning system can become contaminated, reducing the performance of the cooling system and potentially affecting the health and safety of passengers.
