Your Maintenance and Warranty book will give you the correct oil to use but it is probably Total INEOS ECS 5w30. You can get 5 litres for around £25 from Nielsen of Swansea and delivery is in a couple of days. I would buy the oil filter and drain plug washer from Citroen to make sure you get the right one, plus the washer will be less than £1 but a lot more from other shops. The oil amount should be 5.25 litres with the filter change but you may find 5 litres will be enough since the min to max on the dipstick is 2 litres. When filling up though put in about 4 litres, let it settle and then keep putting in a bit more to get the level right to avoid the risk of overfilling. Using a clean funnel when adding the oil helps prevent spilling it over the engine.

 

If you have hydractive suspension it helps access if it is raised to max. To get to the sump plug you will need to remove the engine undershield and it might need a socket or square or hex bit to undo it so best to check before removing the oil filter, its torque setting might be 35 Nm. If you do not want to bother checking first, you could always get a new one from your dealer and then you will know what to use - or ask to look at one when buying the filter and drain plug washer. The filter cover will need a large socket (27 mm) and torque wrench for when doing it back up, the torque is marked on the cover and is usually 25 Nm. A new rubber seal for the cover will come with the filter and a bit of oil on it will help when tightening the cover. Note where the old seal is located in the cover top groove before removing it. With these filters I have found it makes less mess to replace it before draining the sump, use a bowl underneath on the floor to catch the oil that runs out as it is undone and have a lot of rags around it to help catch the drips. Once the new filter is in place, then move the bowl under the sump plug, undo it and let the oil drain out. Use the new washer on the drain plug when putting it back. If the bowl is on a large bit of cardboard, it helps keep the mess off the drive.

Hi Paul thank you for the time for writing a comprehensive reply. I can now carry get everything and have a go myself . I had my cam belt changed by Citroen recently and noticed there was no undertray which should make things a lot easier .
