I just did a 422 mile round trip from south central pa to western pa. I would say that 85% highway. I hit 19 mpg at one point but when I got in the mountains on interstate 68 in md it dropped to 16.4 mpg. With 3000 miles on the truck my overall mileage at this point is 15.2 mpg. I had my cruise set at 68 mph. I still believe I have a miss or studder at 65-70 mph. No codes or cel.

EPA test's at Highway speeds is a average of 48 mph. Max of 80. But the average is 48.
Look at page 2.

I have the 3:55's in an 11 screw 4x4. The mileage over the 3:73's is barely noticeable, there are many new ford trucks where I work and when we compare mileage between the two you will only see about 1 mpg better, on good day. At 115 kmph i get a steady 22mpg, that's on a full tank to and from work with 90% highway. I work 75km from home.

hey i have 2013 fx4 screwand 3.55 gears. the truck has 20 in wheels with 33x12.50 on it and was wondering if anyone with similar wheels on was getting reasonable mpg's? gonna throw the factories back on to see but dealer thought after 1000 miles it would get around 18 to 20 mpg with the big tires

2018 F150 Platinum FX4
My 2011 FX4 SCREW 3.73, 10,000 miles has never come close to 20 mpg highway. The best that I have gotten is high 17's on extended trips, 70mph mostly on cruise control. After reading about similar EcoBoost owners getting over 20 mpg, I was curious if there is something the service dept. could check/adjust to up mileage. Although my in town driving can deliver 15-16 mpg, I would like to get the "advertised" fuel economy. Love the truck, just want better mpg.
Thanks

...My wife drove the truck for the first 20,000 miles, and averaged between 15.8/16.1mpg. I assumed that it was just because she drove in rush hour. But, on a 700 mile road trip where I reset the mpg display before hand, I witnessed her STILL only get 16.5mpg on the highway.
If I had to describe why she gets crap mpg, I would say that it has to do with not knowing when to "coast", not being able to predict the behavior of slow moving traffic (ie: knowing when to creep forward at idle, and knowing when to push on the gas), and knowing how far to depress the throttle when accelerating on the highway, without causing the transmission to downshift. I know it all seems petty and stupid, but it's the little things that account for the extra 2-3 mpg.
