Default Another Ecoboost MPG thread

Hi i have ecoboost FX2 with 3.55 rear end and usualy drive empty. Everyone complaining about mpg not being up to par. here is my numbers since i bought it have about 5400 miles now

55-60 mph average 27-30mpg
60-65 24-27mpg
65-70 21-23mpg
70-75 19.5-21mpg depending on how many hills im going over

many fill ups now and never got below 19mpg average for whole tank and im about 500+ miles on 26gallons

but i only get below 19mpg when driving city and lots of stopping and going not sure why yalls mpg sucks so bad try using cruise control more even in 30-45mph zones will help a ton

ps drove 170 miles to austin this weekend one wa and got 21.5 mpg at 70mph whole trip

I shouldn't encourage another EcoBoost mileage thread but I can't help myself.

I think the differences in mileage you are experiencing versus many of us other EcoBoost owners may include:

1) FX2 - driving a 2WD, not a 4WD
2) empty bed
3) Sounds like Texas to me - no topography (except maybe the Guadalupe Mountains)

Did I mention 2WD? No hills?

I'm with OP. Most of my driving is in town and my average for the 2200 mike life of my truck is around 17-18. Which is great compared to my old 5.4 which was 10-11. Never seen over 25, but I love this truck and am very impressed with the mileage in a 6000# vehicle!

The best I have seen is about 19mpg highway ( after a ECU re-flash). I get about 16-17mpg city....

I do not think my truck will ever see 20mpg....

I'm losing faith. My mpg has recently gone way down. I used to avg. 20 combined. Now I struggle for 18 hwy. Heck I even got better than 18 towing a pop up his summer. Don't know whats going on but the issues are starting to pile up. Lost faith in my dealer too...had my oil changed...supposedly. went to start truck next day and made a funny noise which prompted me to check the oil...black and still had factory filter. They put sticker in my window as if they changed but never did. Not happy.

Maybe fuel stations are switching to winter gas. I'd be wayy pissed about the oil change thing. Even call ford, your dealer will get in soo much crap for that, rightfully so too.
