Im at a loss on my 2015 2.7 Eco, around town on all kinds of roads my first tank I got 21.5 mpg second tank it went up to 22.5,just took a trip to New York from Ohio all freeway and it went down to 19 MPG,we did the math ourselves and it was the same as what the computer in the truck figured,never had something that got worse mpg on the freeway then around town,Really hoping this changes after more miles are on the truck.

Thats really good. What tires do you have? The size of the cabin? Any other mod done?


Also, on a side note, is there really a difference with a tonneau cover?

Heh, here are some cherry picked miles for ya'!

I'm not sure about a tonneau cover but a cab-height cap did not improve my mileage. Improved the ride a bit though.

I went for a trip i had the same mileage as you at 120 k am having the same motor i had change the tires when new for Michelin LTXM/S2 pressure at 35 psi

Fastskiguy

Did those Michelin tires change your mileage?

supercab '15 4wd 3:55 5.0 200 miles@ 75-78 and some traffic for 20miles. 20.3mpg
200 miles on truck
I'm not upset with that. That's basically I4 tampa to daytona and passing through orlando at 4:30pm.

I have a 2015 supercrew, 5.5ft bed. It has the 5.0 engine. I have checked mine both with the computer and by hand calculation, they are very close. At last check I was at 18.6 in town driving, and I got 22.8 on a trip to Columbia, s.c. it is an XLT and has the 3.31 e-locker. I am very happy with those numbers. This is my daily driver.

BTW, Happy New year to everyone.

Echoboost

Well.. for the 2015 ecoboost 3.5, the city gas millage that is listed is generous to say the least. Living in rural areas, I was getting an average of 21MPG and 23MPG when I had stock tires, so I was getting the listed MPG. Having moved to the city I have noticed that my MPG is around 13. So I couldn't get 17MPG in the city if someone was pushing me at the line. Another issue may be this is my first winter with the ecoboost, and I have heard that these engines do not like the cold weather. But I didn't buy the truck for mpg, just thought I would share my MPG experiences.
