Although this may seem really obvious to a lot of people, for the people who aren't as mechanically minded as others, heres a quick guide on how to carry out an oil change, potentially saving you a fair bit of money rather than having the local garage charge loads for the pleasure.

Note: Oil changes alone not to replace full services at the correct intervals

What you will need:

Trolley Jack and Axle Stands or car lift
T40 Torx bit and associated ratchets, extension bars
Clean Oil
New Oil Filter (Oil and Filter available from Vauxhall on Trade Club for Members)
New sump plug O-seal
Oil Filter wrench
Plenty of rags

1) Run the car at idle from car for 5 minutes to warm the oil which allows it to flow easier.

2) Jack the car up and place on axle stands. Also chock the rear wheels ensuring car is safe on axle stands or lift on car ramp,

3) Locate the oil filter (circled red) and loosen slightly with filter wrench. Alternatively hammering a screwdriver through the filter body is the quick but messy way of loosening it.

4) Using the T40 Torx bit crack open the sump plug slowly, ensuring the bucket is beneath it to catch to oil. Fully unscrew the sump plug and allow the oil to drain out.

5) Fully undo the oil filter allowing the oil to drain into the bucket.

6) With both the sump plug and oil filter removed, allow all the oil to drain out of the engine for about 10 minutes.

7) Replace the old sump plug seal with the new one (available from main dealers)

8) Once all the oil has drained out, give the engine a good wipe over to remove any dirty oil that has run down the sides.

9) Prepare the new filter by oiling the rubber seal with fresh clean oil.

10) Screw it the new oil filter and tighten it up hand tight. (Oil filters do not need to be tightened up massively, and over-tightening only make it harder to remove next time)

11) With the sump plug still removed, pour clean oil into the filler cap, watching for the oil draining out of the bottom to be clear and golden.

12) Once clean oil is flowing out, replace the sump plug and tighten it up. Again slightly nipping up the sump plug with a small ratchet spanner is all that is needed. Theres no need to over-tighten it.

13) Fill up the sump with the correct amount of oil, adding small amounts at a time and allowing the oil to drain to the bottom. Regularly dipping the sump with the dipstick prevents over filling.

3.5 litres for 1.4/1.6
4.25 litres for 1.8/2.0
5 litres for 2.2

14) Once the level in the sump is correct, check for any leaks from the oil filter seal and sump plug.

15) Give the engine a final wipe down and clean as necessary.

16) Remove the car from the axle stands or lower to the ground off car lift.

17) Run the car for at least 10 minutes at idle, allowing oil to warm up. Check for leaks again.

18) Stop the engine, leave for 10 minutes and carry out a final dip on a level surface checking oil is between the lines.

Smoke may be given off from the engine bay whilst running the engine, this is just spilled oil burning off and won't last long or cause any harm.

Remember to ditch the old engine oil responsibly and at the correct disposal facilities;)
