F150 Ecoboost real world mileage

[96firephoenix]

I dunno, not my truck. I'd have to ask. Rule of thumb is 1mpg drop for every 5mph over 55. So 18-19mpg maybe?

not always true with a really torque-y engine. My firebird gets 28 at 55 and 31 at 70...

I have a 2014 got it in August and have about 25,000 miles so far in warm weather highway got about 20 right now running 17.4? Mine is a 4x4 Eco boost and put a trailer behind it and it will sink to about 12 going through mountains on I-68 in WV. I like my truck and like the Eco boost but I had a 2007 with 5.4 4x4 and it didn't get much worst than the Eco boost honestly. Just glad to be back in the f-150 than my 2011 explorer.
