I'm not sure if you'll get a huge response on this one mate...i think a lot of guys just use a good quality premium oil,with no particular preference. I always used the Mobil oils,simply because i believed what i read! But they are bloomin expensive now...
Now i use Castrol Edge Sport,purely because my last two cars (both petrol) were supplied with it! (and i had a 15% off voucher from Halfrauds,so bought a couple of cans - the stealers can put that in on my next service,i'm not paying their prices for oil!!)
Do a thread/post search and see what you can find...i think i recall quite a few guys using Millers!
As long as it meets the requirements in your owners manual,i'm sure you'll be fine.
fill her up!
