Bob Rosadini Posted April 30, 2015 Share Posted April 30, 2015 Friend of mine has a 2013 F-250 Super Cab, 6.7, 3.55 rear, bed cover. This guy is meticulous-clean as a whistle,maintenance by the book and its probably never carried anything more than a bag of trash. He just got back from Fla, a 1550 mile trip (I-95, I-287 across Jersey, back on I-95 to Mass.) He set the trip when he started trip , averaged 63 MPH, was cruising at 80 mph, and got 18 mpg. Just he and his wife, luggage for a three week stay. Any comments on that MPG? Quote Link to comment Share on other sites More sharing options...

Just he and his wife, luggage for a three week stay. Any comments on that MPG? Sounds about right. Slow down to cruise at 63 MPH instead of 80 and he'd probably pick up 3-4 MPG. No joke. These trucks are not aerodynamic at all and speed kills MPG! My 6.4L gets 2-3 MPG better at 62 than 72. Quote Link to comment Share on other sites More sharing options...
KTMsc Posted April 30, 2015 Share Posted April 30, 2015 I have a 2015 6.7 F350 with 3.31 gears and at 75 I got 18 exactly over 900 miles. Everyday driving however is 13. 1 Quote Link to comment Share on other sites More sharing options...
Bob Rosadini Posted May 1, 2015 Author Share Posted May 1, 2015 Thx guys-also posted on DieselStop and comments pretty much in line--18 mpg with a heavy foot (80mph) is not surprising.take it to 65 and you get 3-4 gain. Quote Link to comment Share on other sites More sharing options...
Remodelboy Posted January 25, 2016 Share Posted January 25, 2016 Bought my 2016 CC 4x4 just after Christmas and finally had a chance to put some miles on it. Took it from So Cal to Las Vegas and made a few side trips - about 560 miles. The computer said 18.1 mpg when I got all the way into Vegas and by the time I got home, it said 18.5. That was driving an almost empty truck (except for fuel). That's with 3.31 rear end, driving between 65 - 75 and using cruise control as much as I could. I was expecting about 14 to 15, so this is a nice surprise. Gets better mpg's than my FJ Cruiser plus fuel is cheaper. Quote Link to comment Share on other sites More sharing options...
blwnsmoke Posted January 25, 2016 Share Posted January 25, 2016 Were you hand calculating or only going off the display? I see about 17mpg with regen.. if I can go without a regen, I can get between 20 and 21mpg but that regen always tanks my fuel mileage and still net a 17-18mpg average. Towing 13,000lbs I get between 11.1 and 11.5mpg all hand calculated. Just bought a tuner for it that I'll be loading tomorrow. Everything that I've read (experiences from owner with this particular one) is that the regens have gone from every 350 or so miles to 500-600. This should net some really good fuel mileage gains since one is going anywhere from 50-75% further distance per regen. Quote Link to comment Share on other sites More sharing options...
Remodelboy Posted January 28, 2016 Share Posted January 28, 2016 That was just going off of the display. I've read that the display tends to be off by a half mpg or so, but I get sloppy when it comes time to write down the miles. Maybe i'll do it by hand once i get comfortable playing around with the trip a and trip b settings. Quote Link to comment Share on other sites More sharing options...
TP431 Posted October 13, 2016 Share Posted October 13, 2016 Our 2011 250, with about 50k miles on it, consistently gets @ 18 mpg on hwy with cruise on 75; towing is generally @ 12 mpg. Strangely enough when it was brand new it got much better mileage than now (it used to get 22-24 hwy) Quote Link to comment Share on other sites More sharing options...
