Good Morning, I have a 2012 F 150 Platinum Ecoboost crew cab pickup (14,300 miles) , was wondering what kind of mileage do you get on the highway. I travel east to Atlantic frequently up I29, I680 then I80. As you well know it is not level road, there are continous roaming hills all along the way east. I don't get anywhere near 20 or 21 mpg as Ford advertises. Was wondering if you ever travel this area, what kind of highway mileage are you getting. I do set the cruise at 75, so that may be one of the reason for poor mpg. I have even tried filling up with 91 octane and it still doesn't improve. I realize ambient temperature, wind conditions, and number of folks in the cab can infuence the performance. Appreciate your input.
