Me. My edge evo says a little better, but this is a little misleading. It's all highway driving. I run 70 mph at about 1800 to 1900 rpm. I know if I'm on the highway a lot I can get 350 miles to my tank before my low fuel light comes on which if I fill up then I hold about 21 gallons.

Wow that's awful from just going up to 35's. If it is a hilly area my mileage can suffer, but I usually get at least 15 mpg

Lower gears help more on the highway because yeah, the rpm's are lower. She had a v6 though with 35s Mud tires + random stuff like compressors for her train horns and her bull bar.

My favorite gears are 373s. The in between for mileage and acceleration.

Oh yeah, she also lives at a higher elevation.

^Agree. I have the 4.6 with 35s, 3.73 gears and with mixed driving 11-12 is my average. My old 5.4 3V with 33" tires and 3.73 gears also averaged the same MPG. I'm using the iPhone "Gas Cubby" app to calculate.

Cleaning your MAF sensor with the appropriate cleaner or CRC electric cleaner. can help, as well as cleaning the throttle body really well with throttle body cleaner (don't use carb and choke cleaner) they say it can eat the protective coating off an electric throttle body.

I'd also suggest maybe sea foaming through the PCV valve hose, some guys may tell you not to.

Cleaner your air filter, and change your fuel filter. Use a good quality gasoline.

Maybe somebody else can add something. All of these are common culprits.
23 on the highway?!??!?!?!? i never got anything better than about 12 in my truck - My cats are in tact and my truck only has 61K miles on it... I DO drive hard, but I have never seen a 5.4 get 23..... Are others getting 23 also?

Sorry, no way, 23MPG!? This is unheard of to me.
