Better Fuel Economy

[mach14604]

I have a 2015 Expedition with the 3.5 Ecoboost. I would like to get better fuel economy. What if anything is out there for me? Any info or links would be appreciated.

Get a tuner or programmer to start. Search this forum for links.

I bought a new 2015 Ford Expedition Limited 4x4 and consistently achieve the mileage ratings for the vehicle (15 mpg city / 17 mpg combine / 20 mpg highway). I use mid-grade, top tier fuel (89 octane). I now have 9,8xx miles on it.


What mileage are you getting with your vehicle? Do you have the 4x4 option?

5startuning in the vendor section can help you...they provide a programmer and also has a performance tube that will help specifically for ecoboost

I was highway driving over New Years and was knocking down only 16ish. I have 5800 miles on the truck.

Were you driving faster that posted speed limits? Using 4-wheel drive? A lot of cargo and passengers? Do you use top tier fuel? I know the vehicle is rated for 87 octane, but I've found that using 89 octane improves the mileage by about 1 mpg.

I often drive rural state highways and occasionally an expressway with mine. I use 2-wheel drive, unless there is inclement weather. Even when using a/c in the warm weather - I consistently get between 18 - 20 mpg. Very little cargo but a driver and several passengers.
