How can you refit oil filter in a citroen saxo?

To refit the oil filter in a Citroën Saxo, first ensure the engine is cool and remove the old filter using an oil filter wrench. Clean the mounting surface on the engine to eliminate any debris or old gasket material. Apply a small amount of new oil to the rubber seal of the new filter and screw it on by hand until it is snug, then give it a slight additional turn. Finally, refill the engine oil if necessary and check for leaks after starting the engine.
