As Jeff alluded to, I'd suggest going with the recommended 5W-20 as well. It's proven that the lighter 20 weight flows better and get into the tighter clearance parts better during the critical startup and warmup period. In other words, engine wear is reduced.
As far as brands, I use to use Mobil 1 but recently started using Royal Purple in my supercharged F150. I'll probably go with Royal Purple in the Edge when it's time to change the oil in it.
