2015 Ford F-150 – The 23 Gallon Tank That Holds 33+ Gallons

You will never get their however.

2015 Ford F-150 4X4 Supercrew Lariet with the 2.7L EcoBoost, NAVI, Sony Audio plus more – $51,175 as driven incl. D&H provides a 18/23 mpg city/highway rating.



Last night I was sitting at my hometown Shell in Gurnee, IL with the all-new 13th generation 2015 Ford F-150 after spending over 2 hours to top it off for the calibration drive...



When Press Fleet vehicles arrive, the handlers fill them up just before dropping the off. They do not top them off but a first click and then they drive to your home to swap out or pick up the vehicle with another driver.



Standard for the U.S. Press fleets nationwide.

The "Ordeal" about to begin

A look back. With that in mind, when we drove the 2011 2WD Ford F-150 with the 3.5L EcoBoost across the country during the 2011 Ford F150 EcoBoost Fuel Economy Adventure Challenge, we discovered that its 26 gallon spec tank was actually the optional 36 gal. tank with some kind of loop seal plumbing to make the 2WD owner believe he had the 26 gal. tank. With 2 East to West and back East cross country drives, I was refueling with between 33 and 35 gallons at each fill when driving it close to and even some times down to < 0 DTE. I perform top off fills to provide fuel economy accuracy from tank to tank.



Back to the present... I drove about 18 miles incl. the photo shoot location before arriving at this Shell. When I began the fill, first click came at about. 9 gallons as expected. I pulled out the fuel filler spout from the truck and began the ordeal. I added 5.410 gallons at a rate of 0.004 and 0.006 gallons at a click for over an hour. At that point I stopped and went inside for a break.

It is in the mid 20 degree F range here right now and falling so you can understand why. After 5 minutes I went back out for another hour plus and added another 4.649 gallons before there was a stable fuel level in the plastic fill spout.

The included external fuel container spout funnel to bypass the refueling port EasyFuel shutoff flap(s).

All told, after over 2,000 pump clicks from a Full indication and maybe. 9 gallons consumed from its press fleet handler fill, I added 10.059 gallons. In other words the standard 23 gallon tank is actually the optional 34 gallon tank on all 2015 F-150s with some unique plumbing but nobody will spend 2+ hours to get it.

Really wish Ford would pull whatever plumbing change out if the new F-150 and just give everyone the true 34 gallon capacity that it can actually hold without all the drama.



On a positive note, 35+ gallons at 30+ mpg provides 1,050 to 1,100 miles range which is excellent for a full sized truck just like the previous 12th gen offered us quite a few years ago. :)
