How do you change oil filter on a Xsara Picasso?

To change the oil filter on a Citroën Xsara Picasso, first, ensure the engine is cool and safely elevated. Locate the oil filter, typically found near the oil pan, and use an oil filter wrench to unscrew it, allowing any remaining oil to drain into a container. Apply a small amount of new oil to the rubber gasket of the new filter, then install it by hand until snug. Finally, refill the engine oil through the oil filler cap and check the oil level with the dipstick.
