They actually recommend a minimum octane rating of 87 for the GT. They recommend 87 for the V6 and the Ecoboost. You lose HP using 87 octane (35 HP in the Ecoboost). The 435 hp rating in the GT came with 91 octane. You will lose 1% of the HP rating using 87 octane.Ford recommends 87
I use 87, get 34 MPG and more on the highway and have plenty of power. I may try higher octane just to see if I can feel the difference.
