Actually, if you read the manual, it states that the car is tuned to run on Regular OR Premium. There is a slight performance increase if you fill up with premium.

And the difference is a paltry 2 hp, so unless anyone happens to have a preference for any of the additives a particular brand dumps in at the terminal, running premium gas in the MKS is all about psychological, rather than actual, benefit.
P.S. My mileage was also with 2 occupants and 100% dual zone climate conflicting to its maximum (mine set at 60, my wife's at 75).
Ford really has NOT communicated the message about how amazing the MKS' relative fuel economy happens to be even with the base 6 and AWD, something made even more remarkable by the M1A1-like mass it hauls around. To hit the EPA estimates, not just under controlled circumstances (like downhill and with a tailwind) but to peg them with additional "real world" considerations like 1 hour of crawling traffic and perpetual A/C just goes to show the fundamental nature of the quality improvements that Ford is letting speak for itself.
And not that I'd ever advocate substituting marketing "hype" over actual accomplishment, but I'd sure like to see Ford's vehicles enjoy the kind of marketing support they truly deserve. They continue to make the absolute right decision by building vehicles that turn people into brand evangelists, but the "message" can only go so far until they reach the segment of the market that requires their information served to them on a plate. As a taxpayer, I'd have absolutely no qualms about the government handing Ford a $1B honorarium in recognition for their self-sustained existence and renaissance if it meant Ford spending each of those dollars on getting backsides into seats.
That 3.7 L V6 is a gem. I'm off to spend 1/2 hour "walking the lot" at a local Toyota dealer and discourage their potential customers in favor of Ford.
