He ends up at a Ford dealer, gets a new F150. I tell him I've been reading rave reviews about the eco boost motor. He rolls his eyes, tells me thats what he has. And while it is fast (drag race type fast) He is disappointed with the MPGs, when hauling or running empty. He was saying 13 around town, and 15 to 17 on the hwy empty. Hwy towing was 12 to 14mpg.

Sounds to me like the guy likes to drive with a lead foot and drives lots of short distances.

My truck's overall average for 9,000 miles has been 17.2 mpg according to the truck computer. Only about 600 miles of that has been towing. I expect the average to drop considerably since I'm leaving for a 3,000 mile plus trip with the trailer later this week. When I have calculated mpg manually, it has always come out within 0.5 mpg of what the truck computer says. My truck gets 21 mpg at 55 mph on the highway in gentle terrain. Bump the speed to 72-75 and it drops to 18. Typical commute for me of 7 miles each way(2 miles in town, 5 miles hwy at 60 mph) yields 17 mpg. Pulling the trailer, driving about 60, it gets about 10.

I can't answer all the OPs questions, since mine only has about 9,000 miles, but I'm very pleased so far. I traded in a 2008 Chevy 5.3 and the EcoBoost pulls way better, while achieving slightly better mpg.

I had the moisture in the intercooler issue one time when I had been driving at a steady speed in the rain for a couple of hours and decided to punch it to see if it would happen. It did. I took it to the dealer, they reflashed the computer and I have been unable to duplicate the failure since, and I have tried.
