How do you change oil filter on xsara Picasso?

To change the oil filter on a Citroën Xsara Picasso, start by ensuring the engine is cool and the vehicle is securely lifted. Remove the old oil filter using an oil filter wrench, and make sure to drain any oil from it into a container. Before installing the new filter, apply a little fresh oil to the rubber gasket on the new filter for a proper seal, then screw it on hand-tight. Finally, refill the engine with fresh oil, check for leaks, and dispose of the old filter and oil responsibly.
