Wow I have a 6" and 35's CAI and exhaust and I only get like 8-9mpg

I have a 2006 Supercab 5.4L 4x4 with 3.55 gears, an Edge Evo, Gotts Mod, Flowmaster 3" si/so exhaust and 295/70 Cooper STT's on Raptor wheels.

My truck averages over the span of a whole tank about 14-14.5 mpg and that's a pretty fair mix of highway and stop-n-go driving.

I don't know exactly but I get around 350 per tank, that's a 26 gallon tank in a 2007 4X4 Screw. I guess it's around 13-14mpg, that's mostly highway driving but I drive 80+ a lot and romp on the gas.

I get around 14-15mpg mixed, more on the city side, reg cab FX4 with the a/c on blast during the day, windows down at night

rmb_crew

I have a 2010 screw 4x4. Getting 17-18 around town and 20-21 on the highway. Got exhaust and a soft tonneau cover. Hopefully get a intake and tuner soon.

2010 FX4, scab, I get the same as rmb_crew. Gotta change the abbreviations for crew and super cab. The current ones just are not fitting.

Mike FX4

My truck is a 2010 FX4 SCab on 33s and stock suspension. It has zero performance mods. My normal per tank average is about 12mpg mixed city/hwy. Highest I've averaged is 16.5mpg all highway on a road trip cruising about 65-70mph. Most trips (same route) I hang with traffic around 80-85 mph, which usually gets me 15.5 mpg. So for the 1mpg hit, I'll take the quicker trip.

BTW, normal winter mileage is usually down by 1mpg. It drops considerably if there's snow on the ground and nobody around.

I have a 2010 SCrew FX4 with 6.5 foot box. All stock. Highway I get 19-20 mpg. Around town, 13-14 mpg. No engine mods. Just a cover on the box....
