While Motul may be a great oil for some applications, it isn't cheap and isn't always easy to find. What I'd suggest is before switching to a different oil, send a sample in for analysis at one of the
testing labs to see how well your oil is actually protecting your engine. If you're going to do changes at every 3k miles you'll probably find that even modern conventional, non-synthetic oils will offer the protection you need.
Another thing mentioned is warranty. Since you have a new car and it is more than likely still under factory warranty you'd want to use something that meets Ford's specifications. The chance of an oil related failure is small, but should something fail in the engine due to a manufacturing defect the dealer may still want to see service history documentation and if you were running non-approved oil might have problems getting repairs covered.
According to your owner's manual (which can be downloaded
here), Ford calls for an oil meeting their WSS-M2C930-A standard. For economy reasons and with modern machining tolerances there's nothing wrong with using a 5w20 oil, but if the Motul meets that standard and you live in a hot climate a 5w30 should be fine. For added piece of mind you could ask your local dealer and if due to regional climate considerations if they suggest running the slightly thicker oil.
If it were me and I was following the factory recommended 7500 mile change interval I'd probably try the Motorcraft semi-synthetic 5w20 oil. Its personally what I run in my Chrysler Hemi V8-powered truck that calls for 5w20 and from the independent testing I've seen performs very well. It's also cheap at around $11 for a five gallon jug at Wal-Mart.
If you did an oil analysis and for your driving style and conditions a full synthetic would be more beneficial I'd look into something like the Mobil 1 5w20, Pennzoil Platinum 5w20, or one of the other synthetics that meets Ford's standards, should cost less, and provide just as good (or possibly even better) protection. And as always, test the oil or you never truly know how well it is protecting.
