You will need:
- 5l oil, new sump plug seal, oil filter
- 10mm socket to remove undertray
- Sump plug key (7 or 8mm square socket – can’t remember which)
- Suitable ratchet
- Possibly, a strap wrench to remove the old filter
- Catch tray; eg. old oil can with the side cut out
- Clean rags
1. Take the car for a run to warm and thin the oil. Don’t get it too hot.
2. With the undertray removed and a catch tray under the sump plug, start to undo the plug with the key/ratchet. Once it has started to turn, remove it carefully by hand together with the old sealing washer. Be careful as the oil will be hot.
3. Whilst it’s draining (will take a few minutes), clean the sump plug with a rag and fit the new sealing washer over it. Once it has finished draining, wipe any excess oil from the sump and refit the plug/seal nice and tight.
4. Remove the oil filter – it may or may not spin off by hand (counterclockwise). If it doesn’t, use a strap wrench. Clean the mating face on the block once the old filter has been removed.
5. Pour a little of the fresh oil into the new filter so that it starts to soak it up; smear a little of the oil around the rubber seal on the filter and spin it on to the engine – tighten it by hand only.
6. Pour your fresh oil into the engine slowly; stuff rags around the filler aperture to minimise the risk of spills.
7. Clean up any spills around the sump/filter/filler.
8. Take the car for a run and bring it back to check the oil level and to check for leaks.
9. If it’s all OK, replace the undertray.
