It really doesn't matter. And I mean that. Clean oil that is changed often is what matters. I have run name brand oil, I have run house brand oil. The only oil I haven't run is the weird stuff they sell in the grocery store that doesn't have a SAE designation on it.
I would recommend with a older engine to stay away from the 5w oils, they are awfully thin for a truck engine with a lot of miles, but in reality they would work also.
My local parts store had some Peak 15w-40 diesel oil on sale cheaper than their house brand, and I bought a bunch of it and put it in my old Chrysler van. I think it actually made it run a little quieter, that old 4 cylinder hammers pretty loud, but it keeps running and doesn't use hardly any oil.

Any discussion having to do with which oil brand is best will always degrade to something roughly equivalent to arguing over how many angels can dance on the head of a pin. As Franklin said, change it as often as recommended by the manufacturer (Ford). I meet customers all the time at the store that either think there's some way to not change it very often, or ask me if they get the 'expensive stuff' it means they don't have to change it as often...then I get called an a-hole when I tell them such ideas are blatantly false, and to change it as often as the manufacturer recommends, regardless of what kind of 'super-oil' they buy. People...

Walmart is usually the cheapest place for oil and filters. (Get the Motorcraft filter, Frams suck) I usually get Pennzoil 10w30 for the gassers and Motorcraft 15w40 for the diesel.

I agree with what's been said, with an exception. Unless you're running a roller cam motor, you NEED to be using either oil with a very high ppm of ZDDP or a ZDDP additive. After seeing the cam and lifters out of one of my motors that I hadn't run additive in... I'm a believer and see the extra expense as cheap insurance.
Comp Cams markets it's break-in additive for this very purpose, I usually dump a bottle in with every oil change.

Here's some more stuff on it.
5.What solutions does Valvoline offer to the zinc issue?
Valvoline offers two solutions to the zinc issue:
1.Valvoline VR1 Racing Oil: Contains 75% higher zinc than SM motor oil with a balanced additive package designed to work in both racing and street-legal applications. This product will protect older style push-rod and flat tappet engines. Valvoline provides this product in both multi and mono viscosity grades: 20w50, straight 50, 10w30, straight 30, straight 40, and straight 60.
2.Longer-Lasting Zinc/Phosphorus: Valvoline uses an advanced zinc/phosphorus additive that keeps higher levels of phosphorus in the motor oil where it protects the engine instead of poisoning the catalytic converter. Valvoline is the only brand offering this unique additive across its entire line of passenger car motor oils including SynPower -- the only synthetic oil that offers this additive.
I am finding out some of the diesel oils may be ok(Chevron Delo 400 LE 15W-40 Heavy Duty Motor Oil ) but others have had thir zinc levels reduced for protection of emissions equipment.
