How Often Should Engine Oil Be Changed in a Van?

[DiCarson]

Van engine oil should be changed every 7,500 kilometers or every six months. The functions of engine oil are: 1. To cushion the impact load on pistons, piston skirts, connecting rods, and crankshaft bearings; 2. To form a sealing ring between the piston rings and pistons, reducing gas leakage and preventing external contaminants from entering. The method for changing engine oil is: 1. Lift the vehicle, remove the underbody shield, and place a container of about 10 liters under the oil drain plug; 2. Unscrew the oil drain plug, use an air gun to blow into the oil filler port for two minutes, then tighten the oil drain plug after draining and wipe it with a tissue to check for leaks; 3. Reinstall the underbody shield and lower the vehicle, then use a funnel to pour new oil into the filler port.
