What kind of MPG mileage are you getting with your Powerboost?

[JediNut]

Wow... I rarely get over 20 mpg! Is your truck leveled? I am running with Nitto Ridge Grapplers (285/65R20) so they are heavy (61 lbs each)... I am convinced that's what killing my MPG.

Hand calculated last 5 fillups was between 23.9 and 24.5. I have gotten 17.8 when I first bought it. This was a trip to South Dakota ( 3,200 miles) with an average speed of 80 and running around hunting. Best I have ever gotten was 28.3 on a 14 mile trip to town.

My gas mileage improved as the total mileage on the truck increased, this has been the case on every Ford truck I have had since 2009. I am running General Grabber ATX tires and mileage also improved when I increased tire pressure to 40 vs 35 psi.

This is a photo of a recent trip on the interstate with no head wind.

No my truck is not leveled yet. My tires weigh in at 45.4 lbs apiece. That and driving conditions and style could be making the difference. I seldom do over 70 and stay out of boost as much as possible.

Averaging 21 mpg over the last 2 months. Short trips around town so good use of electric only mode.

My truck is leveled on stock sized but AT tires and I average 19.7-19.8 mpg every tank.

I've made several changes including, bed cover, camper, leveled, wheel spacers, small fender flares, tuned, removed front valence and added skid plate... And none of that made any difference that I could measure consistently.

2 things did make a difference in mpg:
1) regular to Super unleaded definitely netted me about 1 mpg increase (and notable power too)
2) going from the stock Hankooks to All Terrain Recons in the same size and weight class cost me 2 mpg right away.

When it was dead stock, tires were aired up, Super Unleaded, stock tires, and driving pretty nice in good weather I'd get 23 mpg, but mostly got 22.

I live off 2 lane country roads that are curvy and hilly and have definitely noticed that when I do the occasional flat Interstate cruising, as long as I keep speeds 65mph and below, can net some pretty high numbers, mid 20s.

19.4 mpg since truck was new after about 5K miles. Got 22 mpg on a 100 mile round trip two days ago.

That’s interesting, the 1 MPG increase for premium gas. That would be about 30 extra miles per tank, so probably not worth it as far as money goes of it costs more than about 1.5 gallons of regular gas to fill the whole tank with premium.

It definitely doesn't pay for itself. Basically a 5% increase in economy for a cost increase of about 20%.

But then you are also gaining notable throttle response and also, if you are already paying for the Super, you can then run a tune that makes the truck a different animal.

For the lowest cost per mile, run regular.
For the highest mpg reading run ethanol free 91-92 (whatever is available where you live).
For the most power run Superunleaded, preferably with a tune.

22.5mpg on the drive today, cruising at 70mph most of that. Truck is all stock.

 

[doolin64]

21.5 in the winter and just over 23 in the warmer months over the last year and half. Truck is all stock although leveling kit and tires go on real soon.

If I drive SUPER conservative (slower in every aspect than anything near me), I might see 18 in very slow around town. I have never broken 19 on level interstate at 74mph. 80? I would not make 16. Ford had nothing to say.

Did you do any powertrain updates and check the air filter?

I have a 22 PB. There’s something wrong with your KR sir.

Morning commute:

Now driving in the city:

and now cruising at 80 on Interstate 10.

 

[TheGoatman]

If you’re not bombing around short tripping it and getting under 19 something’s wrong.

These Powerboost F-150's vary greatly one truck to another. Some get great fuel economy, some not so much. Mine has averaged 19.15 MPG over 38,000 miles (I record every fill-up in a spreadsheet) and above 70mph it gets around 18 unless wind aided or wind opposed when I pick up or lose another mpg respectively. In 21 months of ownership, I've had exactly one long drive (400 miles) on one day where I actually achieved 24 mpg and I honestly don't know how it happened. I drive conservatively as well, using cruise control on highways and whenever possible on longer stretches in town. There are no rabbit starts and I try to break early enough to get my eco report to give me the 100% energy returned message. I find when driving with cruise control engaged on 40 mph roads that electric driving rarely engages unless I tap the breaks and then it will engage for a half mile or so before returning to ICE mode.

Unless something catastrophic happens to the vehicle that triggers a code, Ford isn't going to do anything for you and I doubt you will find a tech anywhere capable of troubleshooting and diagnosing why our trucks aren't getting the 23/24 mpg spec'd.

My overall average is 20.4 last I checked.

Short trips, spirited driving, and extensive idling will drive down that overall number. I'm interested in what mileage my truck is capable of and the pics demonstrate that.

I also find that using cruise control actually lowers my mpg compared to driving the same speed range without it engaged. Cruise control uses boost over rpm to increase speed and stronger than coasting regen braking to slow down. It keeps a tight grip on the speed I select whereas when I'm in charge of the speed I let it coast above and gently increase rpm when below my desired number.

Over my last 6 fillups, I have averaged a hand calculated 21.08 mpg. That includes a trip from Richmond to Orlando and return.
