Home Forums Gear Hunting Trucks and Four-Wheel Drives F-150 Ecoboost in the Real World

I just got a new 2014 Ford F-150 Supercrew 5 1/2 foot box pickup with 3.55 axle, Ecoboost engine, 4WD and Off-Road package. Holy wah, I like this truck. I put a Lear cap on the bed. It came with some pretty aggressive all season tires.

However, the gas mileage has been quite disappointing compared to my expectations and the EPA estimates. I am only getting about 15 mpg on the highway, and that is with a very light foot on the accelerator.

I have heard that these trucks get better mileage after they have a few thousand miles on them. Just wondering what anybody else's experience is with fuel economy in a similar truck.

So far my cure for the disappointing fuel mileage is to stop calculating it and just enjoy driving the thing.

Gas has gone up .50+ in the last few weeks. Does that make you feel better?

I have 2 2014 F150's, both 5.0.

After the issues friends and family members have had with the Eco boost, no way was I going down that path.

Ford actually re-mapped my son-in-law's Eco to minimize the inter coolers issues. It was so lame he traded for a 150 with the 5.0.

My 150's are doing 20.5+ highway and 18+ around town.

Son-in-law said he got less mpg, towing, with the Eco.

My brother got an Eco last month and loves the mpg around town.

When the engine doesn't have much asked of it, it will do what the EPA ratings says it will do. But, if you add things like tires, axle ratios, etc. the mileage can go south easily. Towing makes for the big changes in mileage from what I've seen.
The engine has been a big disappointment. If you really need power to do work, like drive off road, or tow, I'd much rather have a diesel. E

I have a new 2014 Ecoboost 4x4 screw with 3.31 gears and 700 miles on the clock!!!!!!! I really like this Motor!!!!! pulls and performs like a Diesel . Just got back from a 300 mile road trip averaged 22 for the trip at 65 and 70 all highway.......This thing will pull Black mountain in NC without coming out of 6th gear.....No worries about the Intercooler Ford took care of the issue , it involved Trucks Built before May 2012....Ford has sold over 500.000 F150s with the Ecoboost engine by far the #1 selling engine!!!!! less than 1% had Intercooler problems.... If I decide I love it and keep it past the 60K warranty!!!! I will buy a Ford ESP extended 100K warranty for a 1000 bucks and keep on rolling!!!!! My 70 year old neighbor Has a new 2014 4x4 with the 5.0 with 8000 miles on it His lifetime average is 14 mpg....

My 2014 F-150 4x4 Platinum Crew Cab with the V-6 EcoBoost also has the 3.31 gears and gets great Fuel economy. 22 mph Hwy and 16 mpg in town.
It also has plenty of power & will pull anything I hook behind it without a problem. Last 3 pick-ups before this one were all Ford F-250 4x4 Diesels. Don't miss them at all and I've been very pleased with the EcoBoost engine.

Motor?

He's talking about the V-6 Turbo EcoBoost.

Same motor as yours?

Is the only difference then the rear ratio?

Yes sir

right....

Apparently you aren't too familiar with the engine. How many have you owned?

As KMM stated, it is the number one selling engine in the F-150 and has been added to other lines as well. The 2017 Raptor and Ford GT will have the 3.5L Eco also. The Raptor with more power than the old 6.2L. Sorry sir, but if it was disappointing, it would be a thing of the past. I love my 2012.

The Ecoboost sells like Hotcakes!!!!! Dealer had about 130 new 2014 F150s on the lot when I bought about a month ago! over 100 where Ecoboost....My son Decided He wanted one last week....They had sold every Ecoboost on the lot. but still had most of the 5.0s and 3.7s left...Son bought a 5.0..... After driving my Ecoboost for 150 miles yesterday.... He is thinking about trading already. I spent about a month researching and reading about the Ecoboost before I purchased.....I did not even consider the 5.0 After reading all the problems with 5.0 engine Knocking, oblong cylinder...Figured I might as well gamble on the Ecoboost...

Currently driving a 2014 Super Cab with the EcoBoost and 3.31 rear, averaging 15.3 mpg around town and 22+ mpg on the highway....about 1 mpg better than my 2012 equipped with the same engine and a 3.55 rear. Highway mpg in both trucks took a dip above 65 mph.

I had a 2011 ecoboost 4x4 with 3.55s. Mileage seemed to improve after a few thousand miles. Much of my highway travel is East to West. On long trips, it generally got 18 mph driving West and 21-22 mph going East at 70 mph. Above 70 and mileage dropped.

I really liked the truck but had it in the shop three times in about a month at right at 60k for fairly major issues. Traded for an identical 5.0. The 5.0 gets a little less highway mileage and a little better city so averages about the same. It has less power than the eco, but sounds faster.

2013 F150 supercrew. Ecoboost. FX4, 3.55 gears. Cab high shell and a large wooden drawer unit in the bed.
29,000 miles.
50 miles round trip to work with 14 of it in town and 36 on the highway.

Average mpg 16.8-17
As high as 21.8 on a semi long (170 miles) highway trip.

Currently running a 2011 5.0, been very good so far, no issues at a bit over 30K miles. Highway mileage is 20-21.5 (US), city/suburbs is 17. Pulls 5300 lb trailer nicely, last trip was about 12 pulling the trailer through the mountains.
My brother runs a 6.2, slightly less mileage empty but definitely more power. His hauls his 8K trailer nicely.

I have a BIL who owns an older F-250 diesel. He works for Pirelli and can usually get some decent prices on tires from them. Last year he replaced his AT's with some mud tires. He said he lost 2 mpg with the more aggressive tire. May be part of the problem.

I wish all you Ecoboost guys a lot of luck!! I have a 2011 Ecoboost with 44000 miles on it. Now the list of troubles. 3 coil packs,3 plugs, 1 inter-cooler 1 timing chain after installed engine BLEW!!! Spun 2 bearings and threw a rod and heads scored. Ford installed new heads and a new block under warranty.The day they call and told me they would fix it I ordered a 2015 Platinum 5.0 with 3.55 rear.I told Ford that Chevy had a flagship engine years ago called a Northstar they said it was the greatest thing of all time 3 years later they SCRAPED IT! Never again will I have a Ecobust. But when it ran it was a freak! Good luck to all you guys.

I suspect you are probably right. I thought about getting an extra set of rims and tires for summer driving, but the prices on such things are ridiculous and I would never save enough money on gas to justify it.

I do love the truck, though.

The guy that sits across from me at work has one. They get about 8 towing their boat on short trips. We took it out to South Dakota a while back. Got about 12 with 4 guys and a boat. He said that they get about the same with 3 guys pulling 2 4 wheelers and whatever they take for elk camp. They get in the low 20's going to deer camp not pulling anything on 55mph roads.
