5w30 it is. Use oil that meets API certs and Ford spec WSS-M2C929-A for warranty coverage resons.
Keep your OCI at 5000 or less, Ecoboosts have a reputation for higher than normal fuel dilution. I believe it's a byproduct of direct injection.
Motorcraft semi syn 5w30 is a great oil for the price. I'd steer clear of the higher priced full syn oils, being that I wouldn't run a longer OCI. Unless you have money to burn, then the best performing oil I've heard about from the forums seems to be Pennzoil Platinum.

There's another reason for running full synthetic oil - heat. Turbos are hot and the EB's turbos are cooled by both oil and water, so the oil is going to be exposed to quite a bit of heat. Synthetic oils handle higher heat better then non-synthetics. I'm sure the blended oils do fine, but synthetic will handle it better.
In addition, synthetics have lower friction than non-synthetics, so it follows they'll have less friction than a blended oil. What'll I use? Synthetic.

API specifies the acceptable viscosity range for a 5W-30 oil at different temperatures, and ANY API certified 5W-30 oil will fall into that range, regardless if it's Synthetic, Conventional or a blend.
Synthetic oils can be designed "thinner" than conventional oils, which is why you see the 0W-xx type oils available, but to say that a synthetic oil is thinner than a conventional oil of the same API spec is false.

I don't want to start a huge argument on the merits of sythetic vs "conventional" oils, but I have to take issue with your statement.

There have been plenty of studies done that show the reduced friction, and I've seen it myself through improved economy when I've changed out conventional engine, t-case, or differential oil to synthetic. In fact, that's exactly why synthetics aren't recommended for break-in. They don't allow the rings to seal properly, and that's a bad situation.

For the EcoBoost 3.5L V6, I just follow the owner's manual, which states to follow the oil life monitor. That's about 7500-8000 mile change intervals. Also to use 5W-30 that meets WSS-M2C946-A which is at the least a non-synthetic 5W-30 API SN etc... (like Pennzoil non-synthetic). I don't understand where all the conjecture and Internet advice regarding shorter OCI's and the use of full synthetic is coming from if we're to follow the manufacturer's recommendation that is backed by a 5-year 100k mile powertrain warranty

Not an eco-boost, but speaking of the 5 year 100k mile power train warranty. My F-150 is 12 yrs old with 197k miles and I've used Mobil 1 synthetic since the first oil change and have done all the oil changes myself, so I can confirm the oil used. Only thing I've done on the engine is plugs/wires/coils and intake gasket/isolator bolts.

Just got my new 2016 F150 with the 3.5 Ecoboost. After the break in period I'll run full synthetic oil. I have a 2003 Explorer with over 200,000 miles that I've used full synthetic oil in since new and have had absolutely no problems with. In fact, I can't remember if I've ever even changed the plugs in it! Still runs strong, no oil consumption, no smoking. I still be driving it if I didn't need something bigger for towing.
