This is not going to be popular, as most here are going to tell you that you "need" a premium motor oil, but here is the reality:
From the owner's manual for a 2014 F-150, page 301 found here:

You need anything that will meet WSS-M2C946-A; that's Ford's 5w-30 oil spec.
Let's see what we can find in the market place ...

Right there are four brands of conventional base-stock oil that specifically meet the Ford spec for your engine. I'm sure there are others, but my point is made.
You can "want" other fancy lubes, but the engine "needs" an oil that meets that spec. Several inexpensive lubes do just that, and they do so very well.
No lube "
resists fuel dilution very well". And why your M1 has a "
fuel smell" is because the GDI engines tend to have this issue; not unheard of by any means in a Ford EB engine. Using the T6 (or any other brand of oil) isn't going to make this "
fuel smell" go away ...
You call yourself a "
synthetic guy"; that's probably not something you're going to give up easily. But the reality is that your engine requires a lube that meets a Ford spec, and plenty of conventional oils do so. I realize that's hard for some lube-bigots to swallow, but that is the reality of the market place. So if you're true to your self, and intend to save money, then consider these (and others). If you want to follow the herd and just buy the expensive stuff, then just do what you want; that's OK too.
What I perceive is that you're tired of paying for Mobil 1, and want to "
save money" by choosing some other product that still says "synthetic" on the label. You're trying to have your cake and eat it too. Well - I have news for you ... You can!
You can buy any of a number of good quality conventional motor oils that meet the Ford spec for your engine! You can have the appropriate protection for the engine AND save money!
Maybe you only want to save a little money, and not a lot of money? Just remember; what you want and what your engine needs are not always the same thing.
Do as you see fit.
