Currently running 5*'s 91 octane perf only tune on a 6" rough country lift with 35's... can easily get about 18 combined on it with about 20 on Highway.
Have yet to try the 91 Octane Perf/Tow tune where it is said that the ECo Mode on that is way better and more apt for it.
Well, i took a trip this weekend from Boise to the Bruneau Sand Dunes. On the Speedo it was @ 80mph facing head wind. come to find out, through a GPS app, it said we were going bout 95mph. Now i have to try and figure out why I programmed the speedo to accomodate 35" tires but it is stillway out of whack...
Avergaed about 12mpg doing the 91 performance only tune. Tuned it to 91 perf/tow at the dunes before returning home (speedo still messed up) and it was about 11mpg...

I've got a 95 150 with the off road package, K&N intake, and I believe the throttle body has been changed. On a trip I've gotten over 18mpg, but in town 10 or 11, would an electric fan help, seems like the fan really sucks up the power?

It could but I really don't think it will...and if it did, it'd be nominal at best. Those older gen fords that I grew up with were never fond of boasting nice mpg's.
Doing 80 on cruise gets 11.5 MPG, anyone else with a similar setup getting the same gas mileage? 70-75 MPG gets me 13-15MPG, anyone else getting these MPG with the same/similar setup? City driving gets 13.5-14.5 MPG
I have a similar setup but get a little better mileage than you. I’ve got a ‘17 XLT supercab 5.0 3.73 gears 6” lift on 35’s. Highway gets me 17-20 mpg and city I get 14-16. I should note that highway I’m cruising about 65-70 most of the time. After 55 its all aerodynamics dictating the fuel economy. I noticed efficiency goes way down after 65mph.

I've got an '18 xlt supercab 5.0, and have noticed the same. I'm averaging over 20 mpg, and getting 24ish on the highway usually, but if I'm on the interstate much over 75 it starts to drop. Aerodynamics are the only explanation, since in 10th gear the motor is not even turning 2K rpm at that point.
2016 3.5 ecoboost xlt supercab sport and fx4 package. Just bought it a few days ago (and loving every moment driving it!!). Averaging 19 mpg with mostly highway driving after 300ish miles in a few days. 42,000 miles on it currently. I realize this is super junior to be posting figures, but I've driven it a lot since getting it, both around town and on the highway. Quite impressed with the mileage considering I've put my foot into it a few times.
@BlueE30 Glad to hear about your new ride. We just stepped up to the 3.5L after owning two 2.7L vehicles. There is a difference for sure between the two engines. Loved the mileage we got with the smaller engine.

Great to hear about your new 3.5 too. This is my first ever pick up and first Ford. A good friend owns the 2.7 and I’m pretty impressed with the mileage he gets. I’m coming from a couple 4Runners which get 16-17 mpg routinely so getting better than that is quite impressive for me considering this has a ton more power and a lot more size.
Hi All, I've driven 4K miles on my 2011 3.7 XL so far. Average MPG stays pretty much in the 18.5 range and is generally within 1 MPG when comparing the PCU's read out and manual math. Mileage did increase from an initial average of ~17 MPG by switching from 87 octane to 89 octane. Moving up to 93 octane didn't change fuel mileage nearly as much, only around a .25-.5 MPG improvement.
Regardless of ambient temperature I warm the engine to the first mark the needle hits.
I've never been overly concerned with fuel mileage as I tend to be a bit heavy footed and am driving a 6.2L. Mileage is what it is really.. My daily drive is roughly 60 miles round trip, all highway and I'm usually right at the top end of the speed limit (140KPH). I've been averaging about 10.5 MPG. I finally got around to getting a tuner the other day and installed it last night (SCT X4, 95 performance tune). Drove to work this morning and there is quite a bit of difference in the drive, feels more lively, shifts better but what surprised me a bit was that at 80MPH I was just under 2000RPM, before I was sitting at around 2300. Also the registered mileage took a pretty significant jump to boot. I reset my trip A odometer this morning as I do every morning. I dont have GPS and often we get some pretty nasty fog so I know that at around 12 18 and 27 miles I need to start looking for my turnins. I keep Trip B going to remind me for services. Long story short was averaging 10.5 as per fist pic below. And now over 13.. the main odometer readings are the same. Am guessing this will even itself out but thought was a bit impressive just the same.
