The ecoboost is good at towing and sitting idle. Nothing eco about twin turbos. I've read alot of forums and 16mpg is the avg number. For starters you shouldn't be towing with a brand new eco and if you live in hills or city your gonna be getting 12-14. 16-23 on freeway depending on speed

Calculating Fuel Economy
Do not measure fuel economy during the first 1000 miles (1600 kilometers) of driving (this is your engine’s break-in period); a more accurate measurement is obtained after 2000 miles–3000 miles (3200 kilometers–4800 kilometers). Also, fuel expense, frequency of fill-ups or fuel gauge readings are not accurate ways to measure fuel economy.
1. Fill the fuel tank completely and record the initial odometer reading.
2. Each time you fill the tank, record the amount of fuel added.
3. After at least three to five tank fill-ups, fill the fuel tank and record the current odometer reading.
4. Subtract your initial odometer reading from the current odometer reading.
5. Calculate fuel economy as follows:

5. Calculate fuel economy as follows:
Standard: Divide miles traveled by gallons used.
Metric: Multiply liters used by 100, then divide by kilometers traveled.
Keep a record for at least one month and record the type of driving (city or highway). This provides an accurate estimate of the vehicle’s fuel economy under current driving conditions. Additionally, keeping records during summer and winter show how temperature impacts fuel economy. In general, lower temperatures mean lower fuel economy.Metric: Multiply liters used by 100, then divide by kilometers traveled.
BREAKING-IN
You need to break in new tires for approximately 300 mi (480 km). During this time, your vehicle may exhibit some unique driving characteristics. Avoid driving too fast during the first 1000 mi (1600 km). Vary your speed frequently and change up through the gears early. Do not labor the engine. Do not tow during the first 1000 miles (1600 km).

And how are you determining your MPG? *Hopefully not from any screen read-out.

Yes I know I am not suppose to tow during the first 1000 miles but my trailer is only around 3000 lbs and I only have made short trips of about 10 miles each and did not push the truck. That being said, I feel that the risk is minimal that I put too much load on the new engine.
Besides, who reads the stinking owners manual anyway?

I have a lifetime average of 16.7MPG after 19K miles. 99% of the miles are in town.
If I maintain 67 MPH or below over 20MPG on the freeway easily unloaded (5 people inside). Stop and go traffic around 16MPG.

I to came from a dodge diesel. After 26000 miles my lifetime mileage is 15. We live in south central PA with rolling hills and I think that kills my mileage. I average 14.8-15 on the highway running to work. This will be my first and last ecoboost.

Not towing anything but with 5 people and a box full of camping gear we just got 24.77mpg on a 500 mile round trip driving at 65mph with the cruse on.
2012 SCREW 4x4 w/3.31 open rear... Guess I'm one of the lucky and got a good one.
BTW....3hr driving in the rain and no issues when passing.

I had an Eco rental for a few days while my truck was in the body shop. I averaged over 16.5mpg with 3.31 gears. And I drove it like, well, a rental.
