Following advice form guys on the forum (thanks) I've decided to do an oil change on my 05 Impreza WRX. I'd like to do it myself but unfortunatley I'm as mechanically minded as a 8 year old. Does anyone know if there is an idiots guide on the net for changing the oil?

1. warm the engine
2. whilst warming, prefill (prime) the new filter, and keep doing so until it won't take any more oil. This may take 2-4 go's as it soaks into the filtration material inside.
3. remove sump plug to drain old oil (with oil cap and dipstick removed)
4. remove old filter
5. fit new filter and replace sump nut with a new compression washer
6. fill with new oil adding about 4 litres, then check the level and add a little at a time until it's exactly halfway between the marks on the dipstick
7. start engine and leave to run for 10 minute
8. switch off and leave to stand for 10 minutes
9. check oil level and top-up if req'd
10. take car for a gentle drive for 10 minutes
11. leave stood for a further 10 mins and recheck levels and for leaks
