Improved fuel mileage 2010 5.4L
Hey everybody. I have a 2010 with the 5.4L 6 speed trans. Got a little under 10k miles on it currently. I am looking at doing some upgrades to primarily improve fuel mileage. Currently getting a little under 15. I travel mostly backroads and want to do some improvements that want break the bank or void any warranties. Any suggestions or success stories.

- your stock truck is the only thing ford is accommodating when it comes to warrantee . All the good suggestions u get to better ur performance will put ur truck in a non stock configuration Not in fords best interest- if your dealer is cool with mods you probably be fine but just know ford will cover there's 1st if need be
