The 5.0 V8 will run on 87 octane but premium fuel of 91 octane or higher is recommended for best overall performance. When you run 87 octane the engine's ecm retards ignition timing among other things to prevent engine damage which lessens performance.

it gets 402 hp with 87 octane, 412 hp with 91 octane. it will run great with 87. Ford does not specifically give a recommendation on fuel. they only say it makes a little more power with 91+ but it will run just as good on 87 (minus the peak 10 hp loss)

I have done several 300+ mile drives in mine and have found that my highway MPG is actually 1 to 2 mpg better with 87 (thats highway driving only). In the city I use 91 or higher for the HP...I don't notice an MPG difference in the city between 87 and 91.

If you intend on using higher than 87 octane, then you may as well get a custom tune and take full advantage. The extra 10 HP is crank and looks more like 30-40 crank or more with the tune.
