I'd had several F150 customers come into my welding business over the years and I always ask about their trucks. Every one that was an ecoboost said they never ever got the gas mileage the window sticker said. One guy said it went back to the dealer three times and the last time the service manger said we've checked everything we can and the mileage is the MPG that your gonna get. Nothing more. I have a diesel mechanic that lives down the street from me. He is a Ford Man through and through. He says any Ford at 200 miles gets that same MPG at 100K miles. Not diesel but all gas Fords he claims. My last truck I got 17-18 mpg when new and when I traded at 70K miles. I think hes right.

I'm still amazed how this big heavy truck can get 16 mpg around town and 18-19 mpg on the highway. About the same as when it was new...close to 30K miles on it now.

Default Thanks

Thanks to all that replied, I really appreciate you taking time to advise me. I love my truck, but I'm not much of a mechanic so any & all advice is appreciated.
Thanks, Tom G

Default MPG on Ecoboost

Similar situation as the OP. Purchased a 2013 lightly used about 6 months ago. XLT Scab with 6.5 bed, 4WD. Most of the "usual" options (not heavily loaded up) but only unusual option is truck is equipped with 3:31 gears. Would not have been my ideal choice but everything else was "right" with the truck and couldn't find another cleaner or better maintained. Had a friend mechanic go over the truck and am confident that all is within spec.

I've put about 10K on the truck and these are my findings:

Overall since purchase I've averaged 18.1 mpg with combination about 60/40 highway/city driving. Seen highs of 20.0 highway (no load) and lows of 8-12 towing (22' pontoon boat on 30' tandem axle trailer. App.3500lbs total).

Because of the gears (3:31) the vehicle takes some time to get up into 6th gear. Good mileage only happens when the rpm's are around 1500-1700 in any gear. Pushed beyond those revs and mileage goes south in a big hurry.

I've found the key to decent highway mileage is using cruise control as frequently as possible. Truck is VERY sensitive to throttle input and a heavy foot will have it dropping down a gear quickly and into a higher rpm range and consequently lowered mpg. The cc seems to do a better job of throttle modulation than my foot.

Anything over 70mph and mileage suffers. Face it.....these trucks are about as aerodynamic as a brick. As speed goes up, resistance goes up dramatically.

All in all I'm very satisfied with this vehicle. Ride is great (for a truck), it's comfortable, like the looks, etc. This is all based upon coming out of a 2007 Silverado rustbucket with the V6. Any mpg beyond 15 is a real treat now.

I'm averaging 18.1 mpg around town and am very pleased. 3.5L EB and the design of the roads on my side of town are extremely poorly designed for efficient travel (too much stop and go). However I posted about how happy I was in regards to my mpg during a road trip to AZ when I first bought the truck. I got over 23 to Tucson in the canyon, and over 21 back through the southern route with strong head and lateral winds.

Maintenance is going to be key with these trucks and how technical these new engines are. I purchased the maintenance plan with mine to ensure I'm not skipping on scheduled maintenance because of cost. My dealership here in town is highly recommended and very good with its customers, not something that can be b said about others.

If you're concerned about 1 MPG, or any MPG for that matter, sell your truck and buy a Prius...

My family has grown since the 2002 Ranger and 2012 Edge I owned. Was getting 20 mpg around town in the edge and 17 in my Ranger. For me I have a government ford explorer for work and am on call continously so that gets most use. However my wife mostly drives the f150. MPG is important still. My friend has a Raptor and it's a bad *** truck and he gets 13.5 around town. My 4x4 F150 saves me around $607.00/yr in fuel costs if he fills up every two weeks like I do. He probably fills up more but that's how often I fill it up. It may not be a lot to some people but I didn't get ahead in life financially by blowing money unnecessarily. Vehicles are some of the worst investments out there in general because they are depreciating assests, but I keep mine for long periods of time usually. I should not grow out of this truck and can use it for the towing I do now and then, plus it's getting decent mpg and not costing me unnecessarily high fuel costs.

Hey Boossted, I just asked a question, I didn't ask for stupid comments

I don't think I've ever seen (or had) a vehicle that got the advertised MPG. My '13 Escape sure as heck didn't even come close. even off the lot. Bought a six month old Honda Accord that didn't get the advertised MPG, nor did my '92 F150, but that was a few years old when I got it. That number they put on the sticker is just a number they got "in the lab" under ideal conditions as far as I know.
