DIY oil change - what oil?

[GSE]

Got the Monaro MOT'd today with no problems. Car is 5 years old with 32k miles on the clock. I usually have it serviced at the same time as the MOT, but Monkfish couldn't fit me in in time. Looking through the service schedule, as well as all the regular checks, and oil & filter change, it appears that the only 'extra' check at this mileage is the parking brake lining check (which I know is working fine) so I'm considering doing the oil change/service checks myself to save a few quid. I have an oil filter sitting on my desk ready to go on - AC Delco PF46 - the service book says for oil use SAE 0W-30, 5W-30, or 10W-30, so what's a recommended oil to use that is available in the high street - Mobil 1? Car has the Wortec Focus pack and is not used over winter. Also can someone post a photo of where the oil filter is, and do it need a sump plug ring? Couldn't seen anything on the FAQ's re-oil. Thanks!

I've found some photos on the net of where the oil filter is so I know where to look. It looks like it's mounted vertical so it won't piss oil all over the place when unscrewed? However, couldn't get the car up in the air as the ramps I have are too steep and the front spoiler catches. So this weekend I have to do a cut and shut welding job on 4 steep ramps that i have to make 2 long shallow ones. Think I'm going to use the Vauxhall oil.
