Thanm Mikey jd that is ex actor what I am talking about.

"Hate" is kind of a strong word for reality check; this thread needed and still needs it.

Does winter not exist? Pretending it doesn't serves no purpose. The fe is what it is, unless you park your vehicle all winter and walk.

Ever do any towing with that Ecoboost? I've heard some truly horrendous numbers coming from buddies that own them while a trailer is attached. I think the Ecoboost is a good idea, and its a step in the right direction...but it is far from perfect. You seem to be doing pretty good so far.

Next year the farm will need a new 1/2 ton to depreciate out, and its looking like the Dodge V6 is the clear winner in this department right now. Hopefully Ford keeps improving the Ecoboost technology with the competition coming from 'Detroit" and they all come up with something competitive that holds up to regular use.

Good fuel economy in a full-size truck is not an easy task. And many on here try. Very few are able to maintain 20mpg or more with a full-size gasoline truck.

I say this from experience. My old truck was a 2003 Silverado. Rated at 14/18 mpg (15 combined), it took me a fair bit of effort to exceed 20mpg for a whole tank. I did manage it though, and even had my 90 day average over 20mpg for a while. And that is driving it daily, in traffic, stop lights, etc.

I've had my Ultragauge show all kinds of impressive numbers, but at the end of the day, it's the mileage for the whole tank that matters.

I think part of the negative responses come from the fact that many here may expect more from your truck. The Ecoboost F-150 is touted as being very efficient by Ford, and your aero lid should help significantly. By your own reporting:



You seem to be averaging 17-18mpg which is on par with the combined EPA rating of 17mpg.

Averaging that good in cold weather is a coup. We shall see what the next three months bring. Towing is another matter. I had a 4x4 4 Runner towing a 22 ft trailer and was doing good at 12 mpg. It was a 3.5 L V 6 normally aspirated engine. I bought the truck so we can tow a 5th wheel but I don't expect higher numbers for a heavier longer trailer. If I can do nearly as well I will be happy. The aerodynamics of trailers is a separate matter.

for what its worth, "the fast lane truck" on youtube tested a new lincoln navigator with the 3.5 ecoboost towing a trailer up the mountains in colorado. IIRC the average over 7 miles was around 4 mpg. Worst case scenario but it does highlight that even a relatively small engine can be extremely thirsty when you have a couple turbochargers.

3.6 mpg

As compared to what? Up hill both ways I presume? There are no free lunches in thermodynamics. It is a energy equation involving rolling resistance, mass, and air resistance. A diesel might do better but the engine and the fuel cost more. Some of the new 5th wheels have nice rounded noses, completely paneled in under bodies, but still need boat tails to make them work properly. My guess is a V-8 would do as poorly and it weighs more and has more internal friction. We shall see and when I get one I will report on it.

My little 2.0L turbo engine can go from 44mpg to 0.55mpg with about 3" of throttle pedal movement.lol

51 alfa grand prix 1.5 liter was about 2 mpg racing.
