most of the time around here 90 octane is the cheapest and about 30 cents a gallon cheaper.
Would 1 or 2 octane really affect it that much?
On my jet ski it say to use premium but i have always used what is cheapest and the only difference i have found was on 87 it ran 7800 rpms WOT on 90 it ran 8200 rpm WOT and 91 it ran 8300 rpm WOT. so that is why i was asking about the use of premium. The dealer that had on said that they never put premium in just what ever is the cheapest.

Thats an expensive engine, why take a chance with cheap gas. Ford says premium.
Our Aviator is an 03 with about 34k miles on it. Its real easy to get the fuel mileage down real low.
Around town I get 13-14, on long trips 17-19.
The wife on the other hand will get that city number down to close to single digits.
Its a ball to stand on the gas and have people look around for the Mustang, the Aviator really hauls for a big heavy, Luxury SUV.

I don't want to assume too much, but my guess is, the reason it's a question for this poster is the price difference (multiplied by the low gas mileage of SUVs).
Having said that, the basic rule of thumb (KISS) is to follow the manual.
There most likely is a technical reason for this requirement (if they were just doing it to cover there a$$es, they would have it for all vehicles). I know that when I bought my Echo leaf blower (high-end model), the dealer (and manual) told me never put anything but high-test gas in it, something to do with protecting the valves (I don't recall the details, if he really even got that detailed). Granted, the thing sips gas so it's not like filling an SUV, but I wouldn't want to pay to have that motor rebuilt, or to replace the whole thing because I did something preventable.
