Engberg, that is horrible mileage. I can get 13 pulling my 21' enclosed trailer on the highway. Normal hwy mileage for me going 75 is 17-18 depending on wind. Worst I've done is 15mpg at 75 with strong winds.

I do hear some stories of guys around town here getting horrible mileage. Makes me wonder if its not just the driver?

Im on my second ecoboost. Current is a 13 screw with 3.55's

I love the ecoboost so far, though I haven't had the chance to tow anything yet.

Pros: Good power, sound of those baby turbos, fairly quick, easy and inexpensive plug and play power
Cons: 14.5 MPG highway or city, $130+ to fill it up, sometimes when getting on the gas there is lag(not sure if gearing or engine or a comb of both).

Last weekend took a 200 mile trip on the interstate. Set the cruise at 75 and got 13.4 mpg, with a tailwind. got 12.4 on the return trip.

I've owned trucks since the 70's. only one got worse mileage, a 1976 Dodge with a 440. It got 10mpg, not much improvement in 38 years.

I have a 2013 eco, has been flawless so far. No PVC issues, like some seem to think. No fuel dilutioin as others have had. No CAC issues...

I drove her super hard the first 200 miles. I wanted those rings to seat...

Have you talked to a dealer about the MPG?


I have a 2013 4x4 Platinum, 3:31 gears and everything else stock and get 14.7 MPG in the hills of Austin, TX. When I bought it last year in October, the next day I took it to Santa Fe, NM and back for the weekend (~1500 miles R/T) and averaged 17.5+ doing 75-80 MPH virtually the whole way.


Something does not seem right on yours and I hope you get it fixed. This truck blows my lifted, 2005 FX4 AWAY and is a pleasure to drive!

Love the power. Beats the wife's 2014 Mustang. Far as mileage, I am at 16.4 this tank. Never been below 15.9.

You have issues dude. Get it in to the dealer and have them fix it (or drive better?:-)

I have the 3.73 gearing and get 20mpg on I/80 strafing runs from California to Wyoming. That makes a 720 mile range for the 36 gallon tank.

The 5.0 I had in my '11 Lariat was a good engine but no low end torque like the EB does. Amazing how a 213 cubic inch engine can make these heavy truck's haul ***. I've been averaging 17 to 18 mpg with only 2,500 miles on the truck so I'm satisfied so far.

I would have to disagree with you there. The 5.0L never matches the Ecoboosts low end pulling torque even when revved. The 5.0L may get closer as it is revved higher, but it still is far from the pulling power which this is very apparent with when pulling a trailer with both. Unloaded WOT, they are similar since the Ecoboost starts to loose more of its torque up high, but still keeps it above the 5.0L. The power of both of these engines are at their closest points between 4,000-5,500 rpm, but before that the Ecoboost has way more power hands down.

OP, you will not be winning any awards with the Ecoboost when it comes to fuel mileage, but if you are looking for power over a broad powerband then the Ecoboost would be your engine. It is not necessarily how much power it has but when. Think about it this way. The new 2014 GM 5.3L has to climb all the way to 4,100 rpm to get its 383lb-ft of torque for a brief instant and then it quickly falls after that. The Ecoboost is above that 383lb-ft from about 1,800 to 5,300 rpm, and well above it at 2,500 rpm. So it is basically which would you rather have..... A brief instant of peak torque at 383lb-ft at a higher rpm or being able to have more than 383lb-ft on tap for over half your rev range. It makes a BIG difference when pulling a trailer and even more so with a tuned Ecoboost.

The other downsides to the Ecoboost are the issues it had coming out of the box like the CAC condensation issue. However, that is to be expected with ALL new engines and you can either decide it is worth it for you or not. For some it may be and other it may not. For the most part the issues have seem to be ironed out by now so bringing up past problems that have been fixed is about as useless as a one legged man in an **** kicking contest especially when you are looking to buy new.
