For a new car, the engine oil should be changed approximately every 5,000 kilometers. The replacement method is as follows: 1. Use a jack to lift the vehicle, locate the oil drain bolt, and loosen it to drain the oil; 2. Unscrew the oil filter and place a container beneath it; 3. Replace with a new oil filter and add fresh engine oil. The functions of engine oil include: 1. Reducing friction and high temperatures; 2. Cooling and lowering temperature; 3. Cleaning and purifying; 4. Damping and cushioning; 5. Preventing rust and corrosion. Engine oil, also known as motor lubricant, is composed of base oil and additives. The base oil is the main component of lubricating oil, determining its basic properties, while additives compensate for and improve any deficiencies in the base oil's performance.
