How do you change the oil in my Peugeot Boxer 2.2 HDI?

To change the oil in your Peugeot Boxer 2.2 HDI, first ensure the engine is warm, then turn it off and let it cool slightly. Place a drain pan under the oil pan, remove the oil drain plug, and allow the old oil to fully drain out. Replace the drain plug, then remove the old oil filter using an oil filter wrench, install the new filter, and refill the engine with the appropriate type and amount of oil through the oil filler cap. Finally, start the engine, let it run for a few minutes, and check for leaks and oil level.
