I have owned my Eco for about 2 months. I traded in my 04 Screw 5.4 and am not looking back. Absolutely love the truck. Just took a 2 hour trip to Detroit on the expressway running 75 and averaged 19.5 for the trip. At least that's what the cluster told me. I didn't check it with math. I only have 2,300 miles on it so hopefully the mileage will get even better. The Power is awesome, They are quiet and have a awesome ride. I don't think you would be disappointed. I know I am not. I just hope it lasts.
Lots Of Mustangs and a 2014 XLT Ecoboost Supercrew!!
