2014 ford f150 3.7 v6 2wd gets est 17/32.

You will have to go with a smaller engine, smaller truck. And then you are driving a narrower high vehicle more prone to rolling than a full-size. Personally I like a hatchback type 4-banger car for work and a big 4x4 for the heavier duty. And I have taken the hatchback fishing and hunting too plenty of times as well as hauled 8ft 2x4's home in it. My 4x4 is a suburban - discussing its gas mileage makes me a little sad, although on a trip it can squeeze out 17MPG or even 18 on a good day - but it sure doubles well as a family "van" and wood/drywall/lumber hauler.

Our field engineers just upgraded from 2011 and 2012 F-150's to 2013 and 2014's this year, about half of the guys got Eco-Boosts (course of 27 guys, so around a dozen eco-boosts), EVERY ONE OF THEM has said they aren't getting any better mileage than their old trucks were. They're hitting 16-19mpg on highway (all we drive is highway, and we all keep track for reporting purposes). Supposedly, according to the dealerships, the Eco-boost doesn't start working for the first 20k miles (one dealership said 100k!!!! facepalm), so our guys tried to be patient with the trucks. After 50kmiles on a few of them with no improvement, we had 3 guys do warranty returns on their trucks because they thought something was wrong. 3 new Eco-boosts, same story, crappy mileage. This fleet is almost pure highway driving, most guys putting on 3000-5000 miles per month.

On the other hand, I had a 2010 Dodge Ram 4.7L that I got an honest AVERAGE 25mpg over 8mos. When I compared engine hours to miles driven during the lease, I averaged 72mph. Some tanks came out just over 28mpg. I'm the type that drives 7mph over the limit, so my interstate speeds were 77 or 82mph. Truck had ~20k on it when I picked it up, I turned in the lease at ~112k after 8months.

Mine doesn't. I only have 20k miles on it, but I'm getting 16-17mpg highway. My 2010 and my 2012 got the same, over 200k and 180k lifespans for each respectively (both started tailing off a bit after ~165k, dropped down to around 14-15mpg by the time I upgraded). Commuted around Chicago for a few weeks this winter, been getting about 8mpg in town.

Sadly, my 1991 F-150 5.0L used to get 18mpg highway over a 480k mile life, and the 4x4 was WAY better than the new ones. Although she did start drinking about a quart of oil per tank by the end. My 1993 F-150 5.0 4x4 got 16-18mpg, but she threw a rod at ~230k miles, so that was the end of her. My 1997 5.0 F-150 had a lower geared rear end and 'ton and a half' suspension under the rear end, she didn't get as good, ~12-14mpg empty highway, but I rarely didn't have a trailer on it.

1992 Chevy S-10 Ext. Cab; 4x4; 4.3 Ltr. V-6 Standard 4-speed; 27 mpg. highway

1996 F-250 Ford 4x4; 7.5 ltr. auto trans. (you don't want to know mpg)
