I don't care what kind of gauges you have, the only way to figure fuel mileage is to:

1)fill truck up
2)drive
3)fill truck back up
4)divide # miles traveled by # gallons required to fill.

If you do this I think you will find that you get neither 24 MPG on the highway empty or 9 MPG towing your boat. Your hwy miles will likely be a little worse and towing a little better. Most non turbo v-6 half ton truck wont make 24 on the hwy empty and a turbo is just gonna make it harder to do.

Didnt mean to start a 'Haters' group!
I am 58 yo, starting fishing in a 16' jon boat with 10hp. Sears motor. Took one helluva long time and hard work to finally get a dream rig set-up.
Didnt say i couldnt afford the gas. Just asking if anyone else has this problem and if so, did you know of a cure or issue.
You boys are tough!

The 14-15 mpg is the average I'm receiving when towing.
A lot depends on the fuel and habits you have.
Mid grade is great.
The instant mpg on the screens is not your overall avg.
Do a trip with a full tank. It now displays all four areas of use.
Gallons used.
Exact miles driven.
Time.
Mpg avg.

i have a 2012 eco bosst gets 13.5 towing 20 foot bass boat at 70. and 21-22 not towing on the freeway. 18-19 pure city driving.

That's why it's good. I love that motor

This is pretty much what I am getting too. I've only had the truck for about 6 months and have 16,000 miles on it though.

They start getting even better around 20 k
Takes longer to brake in because they are balance and have closer tolerances.
Synthetics.
Keep in mind guys. I make incredible deals on these trucks.
So call me if I can help.

mine is one year old with a little over 31000. for sale in the classifides by the way.

DO NOT use your computer to brag about gas mileage on any new vehicle these days. The odds of your computer being accurate compared to doing the proven hand calculation are slim to none.

Towed a 25' enclosed motorcycle trailer from Colorado to Georgia, moderate load, at reasonable freeway speeds. Kept pretty good records for a business on gas mileage. Almost broke 9mpg.

I only hand calculate mileage. Besides my old truck doesn't have those fancy mileage computation thingys. lol

I have a 2012 FX2 Ecoboost and I pull a 19' BassCat with it and my results are pretty much the same as above.
Here is the difference between this truck and the rest>>>The Ecoboost pulls like a diesel. No huff, no puff, no gear switching. Put on cruise on non hilly terrain or lock out 6th on hilly terrain. It is a beast thru out the torque curve.
Hands down the best truck with or without a boat behind it I have ever owned.

Your right Nitro. That's why I said to use the mileage and gallons used calculator.

I am currently looking at Ford Trucks but have not pulled the trigger as yet. I am trying to decide if I want the ecoboost or go with the small V8. I have had good reports about both but am trying to filter out the mis-information that you normally get from current owners. I currently have a small chevy V-8 that in my opinion does not pull my z-21 Ranger as it should. Any help would be appreciated.
I can go either way on the new truck but I want something that will pull the boat without changing gears all of the time and where I don't have to stop at every corner gas station.

Numbersguy, I was in the same place as you for the last 6 months. finally went with f150 and eco. Not at all disappointed and would do it again.
