How do you change the engine oil on the citroen Picasso 1.6?

To change the engine oil on a Citroën Picasso 1.6, first, ensure the engine is cool and position the vehicle on a flat surface. Remove the drain plug from the oil pan to drain the old oil into a container, then replace the plug once drained. Next, replace the oil filter using an appropriate tool, ensuring the rubber O-ring is lubricated. Finally, add new oil through the oil filler cap, checking the level with the dipstick to ensure it’s at the correct mark.
