Yeah the mpg's on these trucks is terrible. My cummins diesel gets better mpgs than both me and my wife's f150s combined

when I bought my truck I barley made 9, did some stuff and it jumped to 12-13 city. that's what my cousins 5.9 mag makes

For me I guess it's not bad considering the lift and 35" tires I got on it...I've talked to a few other people that's getting just a ad more with 265-285/70s on

Adams21

What did you do to yours cuz I need ideas...I'm alrdy looking into lower gears which people talked about on here...I need horsepower more than anything without compromising my mpg of gas

Guess I'm doing good with 12-13 on 37's. Got almost 15 with mostly hwy miles on a 400 mile round trip last weekend.

Edit:: that was cruising at a leisurely 60 mph also. No hurries no worries & lots of scenic back roads.

Yes sir your doing dam good...do you have the 5.4?

Jefk

the best ive done is 15 on 32's cruising at 50-55 for a couple hours. I suppose that's not bad when you ad a 200 pound steel bumper/grille guard. gotta love them back roads

My lead foot finally trimmed a few pounds when I turned 18. My gears 3.55 stock, k&n air filter, GOTTS mod, aftermarket exhaust( I run a dynomax bullet, its straight through), basic upkeep, wix oil and fuel filter. I'm going to swap the fan for electric and I figured out how to bypass the rear o2's on the rear two cats so I'll probly knock those out soon. The way I've heard it, more hp = more mpg because to motor doesn't work as hard. My gains are essentially from clearing up/smoothing the trucks airflow basically. depending on which motor and gear and stuff you currently have the butt dyno will feel a difference. haha

I get 12-12.5 constantly, I don't know what my type of drive would be considered, my drive to work typically backroads going 50 for about 10 minutes is the extent of my work commute. I have gotten 15 before on the highway, cruise control set at 60.
