20+ mpg through the Rockies is surprising indeed. This is curious. I wonder why the difference.
Fuelly reports a 13.4mpg average for the Platinums (no records for the King Ranch, which ours is). That's similar to my experience and what other locals here report.
But then Fuelly reports a 16.6mpg average for the Lariats, with a larger sample size.
70-ish mph highway speed may account for some of it. 10% ethanol in the fuel perhaps. More weight in the higher trim levels. Might be lots of little variables driving the number down... but 20 on the TransCanada in the Rockies vs 13 in Iowa is weird.
I might try a Scangauge to see if the computer is reporting correctly.

Part of the problem with Fuelly and pickups is the various configurations of trucks, etc. Those '13 KRs could be 2WD with 3.31 diffs so it's hard to know if they're comparable to yours or not. That's why I picked the FX4 set, at least I'd know they were all 4WD to reduce the variability a bit. The extra weight of a KR is probably much less of a mileage hit than 4WD vs 2WD and it's a much bigger sample size.
You said you're thinking about using a Scanguage to see if your truck's computer is accurate... I don't know if the '13 behaves the same way as my more primitive '07, but the average MPG on my computer is the average since I specifically reset the MPG display, unlike the average since the last time I reset the trip odo like several other vehicles I've had with an MPG readout. I run a scanguage and check that with hand calculation for each tank, but I'm a big nerd.

On my way to Ford dealership this morning. Stopped in to visit a very good friend who is the GM at a Lexus dealership. He showed me a GMC Sierra crew cab, 2015, 4x4, SLT Z71 with 1,563 miles on it he took in trade late last night from an old customer of his. 5.3 V8 Ecotek engine, 3.42 axel, GVW of 7,200#'s, trailer package, Nav, 20" wheels, brake controller. Test drove it and ride was much quite and smoother than the XLT I drove at Ford dealer on Tuesday! Bought it and it's now in the garage.
@Tao, why do you think they traded it in for? Geez. Here's what I have to say- 5.3L @70mph 40% of torque or 153 ft lbs available (without shifting) to pull that trailer VERSUS 72% of torque@70mph or 305 ft lbs to pull without shifting (Eco Beast).
Just kidding- even though they are facts- congrats on the new truck deal even though it is a Ford mpg thread! Sounded like good move.
Forum topic post:
I am getting 12mpg still as a tow average at an average speed of 68mph- I use pump calculation as the computer is a bit higher in mpg at times. I used the navigation to get average speed. This mileage is no different with the 2015 aluminum truck towing as my 2009 F150 steel truck; HOWEVER, as I shared, the power is immense in comparison with all that low-end torque. So, more power. Not towing I do better though- about 2mpg better in town and about 3-4mpg on highway. I haven't enough highway traveling in yet to know exactly- I give the just so far figuring as 3-4mpg difference. Note the percent of torque at highway speed jabbing Tao with to understand what I am talking about regarding power. My old truck was similar to the 5.3 with 140 ft lbs at 70mph so as a result I had the shifting and the roaring going on in hill country.

I also have a GMC with more options that I can find. I have the 6.2 engine with a eight speed transmission and the heavy duty tow package. It pulls a little more than your 5.3, I assure you I can out pull a f150 any day of the week and I pull a 34 AS. I have infinately more power and torque with a nicer ride and silence inside the cab. You made a great choice.
Hey WVollans! Yes he did get a nice truck but what's this about outpulling an Ecoboost on an Ecoboost thread? Ok, your specs are 40% of torque available @70mph without a shift or 184 ft lbs to pull that 34' silver hotel! You're down about 121 ft lbs. Just sayin! The Fords are quiet too.
What I am interested in is how the ecoboosts 2011-2014 do towing compared to the aluminum ones. It seems to me that is makes no difference since my '09 V8 got the same as the new truck. It stands to reason that it makes little difference then if towing with an EB- don't know about non-towing.

This sounds very strange, coming from a couple of Canadians. Are you in some previously unknown-to-me- section of Canada where it doesn't snow??
I live in Vancouver, where it rarely snows. But coming back from Calgary through Roger's Pass three days ago it was -20 C and snowing. I have an AWD vehicle (no low range). But I also find that tires matter much more than drive system, and I rarely tow in the snow.

Agreed. My last three AWD vehicles have included Hill Descent Control. HDC was developed by Landrover, but BMW acquired it some years back.

No, that is the spelling is the entire English speaking world, apart from the US. Given that you are now, what is it, 123 years into your still-in-progress implementation, you probably shouldn't be throwing stones.
PS. Most of us love Americans. Even if they spell colour and labour wrong. And even though they don't write cheques.
Odd. I have a 2013 Ecoboost. 4x4, max tow. 82K miles total. 26K towing a 2013 28' International.
Max MPG not towing is 13.2. Iowa - all flat. Friends report similar here.
20.6? Not buying it. 15.5 towing a car trailer? No way.
Great truck to be sure - fantastic in fact. But 20+ MPG is a reporting error.
Please don't call me a liar. I'm driving this truck, not you. I know exactly what it is getting for fuel mileage. I am the person putting the fuel in the tank. I'm probably just a much better and more careful driver than you are.
I've tried 91/92 octane in my truck and it literally made zero difference. Same power, same MPG. The motor is tuned for 87, so that is what it gets. I've never heard a single ping up any grade towing any load.
I did a test this afternoon. Me and a 90lb German Shepherd. Otherwise empty truck. Fairly flat I-80 in Iowa. Engaged cruise control ~70mph, reset the computer, sat for 45 minutes. Result attached.

13.6 mpg.
Truck window sticker attached.
Weird. Speed related clearly.
Hmm... 4WD KR. Didn't the '13 KR have the "4A" setting like the current series? I wonder if your truck is never fully disengaging the clutch packs that manage the 4WD system and causing more drag than it should be when you're in 2H.

Hi, I think something is wrong with your truck; Mine gets about 10.8 MPG while towing a 6,300 lb rated 25' Airstream. Just generally driving around, I get about 16.5 MPG. On a freeway test, [reset mileage computer] going 65 and 70 MPH I was getting around 20 MPG. [This was only about 40 miles on the freeway with slight ups and downs. Not really hills]
Seems like a lot of people are getting quite a bit better mileage than I do, but they have 3:55's or 3:31's compared to my 4X4 with 3:73's. And they might drive slower than me too.

For what its worth here is my 2 cent worth
I drive a 2012 F-150 Platinum with 36 gl tank Ecoboost. HD Tow 3.7 rear with 76,000 Miles. The last couple of years strictly used for towing. AS 2013 - 30' International.
Around town in FL and IL average mileage 15.2 without trailer.
At 70 Mph no trailer cruise control set average between 17.0-17.5.
Same conditions at 80 Mph it drops to between 15.5 to 16.
Towing flat country at 65 to 67 Mph it is 10.5 mpg. Cruising at 70 to 72 Mph
(this seems to be the sweet spot 2,000 RPM) it is around 9.0 to 9.5 mpg.
The grade of gas doesn't seem to matter although I use mid-grade when towing. I experimented early to see if I could get the advertised 21 Mpg, on a flat road in southern Illinois at 50 miles mpg no stopping just rolling, I was able to coax 20.5 but that is not possible in normal driving. As soon as you have to stop at a stop sign and restart it drops drastically.
