To explain better. With my 2000 F250, I could coast down a hill to my work and make it back to the top of the next hill without even having to hit the gas. Now, I can't even make it halfway up the next hill after coasting and engine braking before I have to hammer the gas to get to the top.

I bought a new 2012 about a month ago of the 4X4 Platinum flavor and now have about 4000 on it. If I keep it about 70 on the highway it seems to hover around 19-20. Town driving is 15. The first oil change is around the bend and Ill be going with Amsoil.

I have a FX4 supercrew with the 5.0 and a 6" lift with 35" bfg AT's. Also put a Air Raid CAI and Magnaflow cat back exhaust and I consistently get 12-13 mpg in town and 16 on the highway at 70 mph.

I almost went with the 5.0 kind of wish I had. The Eco doesnt seem like its going to be that much greater on gas.

I drove the EB but I couldn't get over the sound of the V6 in that big of a truck. Just like the old school V8 sound. I know if you ad a good programmer you can get some really good gains because of the turbos.

Thats probably down the road for me if I keep it. I really wanted the Raptor but had zero practical application for what I use it for. The diesel was probably the best option but I could not get over swallowing another dollar a gallon for gas.

I traded my f150 11 with 5.0 for the 12 eco boost. Now Kind of wish I would have kept the 11 5.0. Don't get me wrong I like the truck but with the problems the ECO is having ( I've been lucky, just had the stall issue at 22000 miles for first time. ) I thought the Eco would get at least 2 mpg better than 5.0 and they are almost identical. Seems like staying under 65 is big difference in mpg with ECO I can average almost 18 doing that but as I spend most of my time on Hwy where 70 is norm averages about 16 on Hwy.

Ive had both, the difference between the Eco and 5.0L over 18500km on the Eco, and 17,000km on the 5.0L is 0.1mpg in the difference. You're right, the Eco does do better at lower speeds when its out of the boost. Mileage shouldn't be the reason to choose the Ecoboost over the 5.0L. I'll probably go back to the Eco once I'm sure the intercooler issues are resolved. Maybe... I love this 5.0L lol.

Exactly, I got it because it does not like to down shift hauling heavy loads like a na engine. Not that there is anything wrong with the 5.0 downshifting to make power, personally it just annoys me when towing which is why I went with the Ecoboost, MPG had nothing to do with it. I'm not bashing the 5.0 and its capabilities, just my personal preference that I do not like a lot of downshifting.

The bad ecoboost gas mileage in a 6,000 lb truck is simple to understand. Twin turbos = more fuel from fuel pump, it baffles me that everyone with a eco loves the big rush of torque when the turbos start spooling, but don't understand when they can see their fuel guage moving toward empty

That said, the guys with the great eco mileage MUST be staying out of the turbos...
