Oil brand does not really matter. Changing it regularly is 1000x more important than what brand you use. If the oil meets the API SM spec (and pretty much every oil does, even Autozone), it's good for at least 5k miles and your engine will outlive the rest of the truck if you change the oil on time. Synthetics are great if you drive in extreme temperatures, beat the crap out of it, or want to extend change intervals. If you don't do any of that, it's probably not necessary. But you certainly still could use it if you want.
The brand is usually the LAST thing I consider when buying oil. When I buy oil, my priorities are:
1. viscosity. Go with what Ford says (5w30)
2. type of oil (conventional, synthetic, syn blend) See paragraph above. I personally use synthetic in everything I own, even my lawnmower. It's not that much more than conventional, and gives me extra peace of mind.
3. Price. Whatever's cheapest for me.
