V8 petrol engine: Anyone changing oil at home?

[notorious]

OK, I'm going to change oil today and I'm going to do it myself in future.

Why Myself? Why not?

* I hate to "outsource" operations I can do myself since I know I will do my best for quality. Not for time, or for low cost.
* I like to change oil frequently. As soon as oil starts to get dirty. And oils with high washing properties gets dirty relatively soon (3000 miles), so I change it often. Yes, I'm that crazy.
* Ben has disappeared. I can't let even this simple operation for people I don't know, including Audi dealers. Besides, I'd like to visit Ben with serious stuff, not oil change. Oh well, hope Ben will return soon.

I'd like to communicate with someone who do this operation at home. BTW, is it legal in the UK to change oil at home? It is illegal to eat apple while you drive in this country, this is why I'm asking.

I've read ETKA and http://www.audipages.com/Tech_Articl...oilchange.html, but still not completely sure I know all the detail.

Here's what I have:

1. Parts: New genuine Audi filter with rubber O-ring. New oil sump plug sealing washer. Don't have oil filter plug sealing washer. Not sure if this required to be changed every time. I don't write here part numbers since they can be different for different V8 petrol engines.
2. 3 x 5L bottles of Mobil one 0W-40 New Life oil (VW 502 00 specification). Should be good to 2 oil changes (7.5L per change?)
3. Pela Pro 14L Marine Oil extractor. Ben doesn't recommend to use extractor. ETKA recommends to use the extractor. Not sure I will use the extractor, but here it is: http://www.pelapumps.co.uk/default.aspx?a10page=pl14k
4. ~ 20 L canister for used oil
5. Relatively small tray from Halfords that they claim was designed to collect spilled oil. Looks a bit small for me.
6. Halfords torque wrench. Love that one.
7. Halfords 100 peice tool set with different wrenches.
8. This is absolutely cool one. Two piece 67 inch Race Ramps: http://www.raceramps.com Love them.
9. Paper towels and surgeon's gloves
10. Halfords mats to work under the car

If you change oil yourself please give me some tips. Don't write War and Peace. Important tips only. And please don't use this thread to discuss which oil is best.
