I drove a eb as well and saw 15 range with mix highway and city driving. Funny cuz the window sticker said 15 city 21 highway. But my 2010 window sticker Showed 14 city 18 highway and in 7000 miles I have never had a tank better then 15.5 mpg. 100% highway best was 15.5. My guess is the eb motor will not come close to the advertised fuel economy on the window stickers

My 2010 Screw, 4x4, 6.5' bed 5.4 averaged around 14 mixed driving. My wife's 2009 Screw, 4x2, 6.5' bed with the 4.6 averages 16.8 same routes. I'm hoping the Ecoboost (same configuration) will get close to the same mileage as her 4.6 3V, I love that truck.

Another thing to consider is gas mileage might increase as the engine breaks in.

We do not know for sure what axle Ford tested each configuration with. Just because a window sticker for a 3.7 4x4 has a 3.73 does not mean that the
epa numbers on the sticker was for that configuration

The ecoboost 4x4 is rated at 21 and I have heard multiple reports of folks getting around that and better. All of the Ford guys taking the demo trucks around the states were reporting better than 20- give them time to break in before you guys start crying.

I read somewhere today, this forum or another that the ecoboost is programmed to run rich for 3000 miles to break the engine in gently. After that expect mpg to increase

Here's a video a guy put up with his 2011 fx4 ecoboost w/ 3.73 gears. He puts the cruise on at 70mph and resets the mpg guage for 7-8 miles. Pretty good video:

The ecoboost for sure will get better than any 5.4 did. But to expect 25mph is just not gonna happen. This is still A full size pickup. With 365hp and 420 lbs of tourque. If I can get 18 I will be jumpin for joy. Afterall I am buying it to do some hauling! The best I do now with my 4.7 durango is 16 and that is empty going down hill. It only has 295 hp and 300 lbs of tourque.

This..Again? Really.
The increased fuel consumption on these vehicles when new is nothing more than mechanical friction causing parasitic loss until the engine is "broke in".
That is all.

I have never had any engine that's mpg increased considerably once "broke in". So if an ecoboost gets 12mpg when new, its not ever going to get much better.

Maybe you should search around and read about "supposedly" how Ford has it programmed for the first 3000 miles to break it in gently.

I wonder if winter blend gas has anything to do with the lower than expected fuel mileage people have been getting?? Living up here in the northeast, my fuel mileage has always dropped in the winter. It seems even worse now with this 10% ethanol crap.

Why is there seemingly no 3.55 axle available??? With that much torque available down low, it shouldn't pose a problem for most Folks.

That's the axle ratio I would get in an EB. I have it in my current 5.4, and it tows just fine. 3.15 and 3.31 drops the tow rating too much. Not all are available with every trim anyway.

New Ecoboost

Just drove my brand new EB from Houston to Ft. Worth yesterday evening on I-45 and got 18.2 averaging 75 mph. It is a 4x4 3.73 157 with 120 miles on it at the beginning of the trip". Thought that was decent, but it also seems to be improving a bit as the engine wears in. I expect to continue to see a little improvement.

What are you getting city or mixed? I want to pull the trigger on one but I'm nervous about getting rid of my wife's 2009 4.6L. She's averaging around 17 mixed, best we've EVER gotten out of any truck we've had so far including diesels. Makes me nervous to get a truck that might get worse mileage though I LOVE love LOVE that EB powertrain!

Man, it's tough to say this early into owning one. I will keep tabs on it closely and feed info when I can. I just drove home from work, 36 miles, of mostly highway and managed 22, but i was trying REALLY hard. I maintained speed, but was barely pushing down at all. I also had a 4.6 and got around 17 as well with 3.08 gears. This is just a projection, but I am kind of thinking the average mixed is going to be about the same, but highway will be a little bit better - time will tell

ecoboost mpg results

I have put 1300 miles on so far. I have four wheel drive crew cab with 3:73 gears. My average mpg so far is 17.5- 18.3. On highway @ 75mph on cruize I got 19.4mpg. On flat rd @ 55 with cruize I got 23-24mpg. Most of the time 55-62 normal driving hills, curves etc. Average is 17.5-19.5 THATS AVERAGE I tend to speed, I will say so far its awsome for a big powerfull truck. I have a diesel that doesn't do as good. I also have diehard chevy friends that a very impressed. I traded a 2010 chevy silverado 4 wheel drive crew cab for this truck because chevy didn't ever get over 15mpg and when I towed my trailer I got 8mpg. I will be towing enclosed trailer that weighs about 7200-7500lbs in april so will see what mpg are then.
