Figured I would throw in the 1 year update.
If you don't want to go back to the beginning, just a few days over 1 year ago I bought a 2016 F150 XLT Supercrew 5.5 Box 4x4 with the 2.7L Ecoboost to replace a 2004 F150 XLT Supercrew 5.5 Box 4x4 with the 5.4L V8. Other options on my new truck included the 302A package, 36 gallon gas tank, FX4 package, Sport Package, Trailer Towing package, electronic locking rear axle, upgraded LT All Terrain tires (factory). I added a tonneau cover (Truxedo lopro QT), rear wheel well liners (Ford Accessory), splashguards front and rear (Ford Accessory), and all weather mats (also ford Accessory pieces), and a dualiner bed liner.
Stats to date:
Current Mileage: 15,800 miles
Average Fuel Mileage to date (computed - not the lie o meter): 19.1 MPG (Old truck in the exact same usage was at 14.2 MPG)
Repairs - warranty or not: None
Maintenance: 2 Oil Changes, both dealership done with motorcraft 5w30 and filter
All in all, I'd buy the same truck again in a heartbeat. No warranty issues or other issues to note. Sync 3 was updated and now has Android Auto which works well for the most part. Excited to get waze on that platform someday...
Fuel mileage is great for this size of vehicle (and this one is likely the heaviest configuration you can get with the 2.7). If you keep your foot out of it, it does very well. Just did a 350 mile run last weekend and averaged 23 MPG doing between 65 and 75 mph. The engine has wonderful power and will move the truck in a hurry!
Towed a boat and was loaded near payload recently. Zero issues with power and honestly was in just about every way superior to towing with the old 5.4 3V. Averaged just shy of 14 mpg on that run. You get eco or boost - not both. I expected this and for the frequency I tow, this is just fine for me. This is also similar to the MPG delivered by the 5.4 3V towing the same boat and payload.
Using Torque, I can monitor and note that the engine does take note of higher octane fuel (recommends 91 octane when towing or for additional performance) but runs just fine on regular 87 octane.
The only quibble I've had is with the dealer service on the oil changes. The first dealer (my sales dealer) did the change correctly, and took their time. The second dealer (closer to work) did not. They badly overfilled it on the first shot (discovered a few days later). You have to wait at least 15 minutes to check the oil level, preferably longer or the overfill can happen. Even Edmunds had a dealer do this to them. Fairly common to hear on the F150 boards too.
All in all, super pleased and I smile everytime I drive it. Would easily recommend one to anyone looking at a full size truck. Don't let the small displacement fool you - the 2.7 is super capable. I drove the 3.5 EB and the 2.7 EB back to back at the time and could not tell enough of a difference to warrant buying the 3.5EB (and I don't tow heavy enough to require it or the V8).
