what kind of gas mileage are you guys getting from your stock trucks ? im seeing 12-13 mostly city driving . A/C is on most of the time.

 

with my 4.2L I get 19 Hwy, and 16-17 City (with AC)

 

05 5.4 k&n intake + flowmaster... 12city 16-18highway

 

When my truck was stock (with stock tires) I got around 13-14 or so city and 21 highway. People hated driving with me on the highway though, No AC and no more than 65mph.

 

I get an average of 15. Stock 4.6 with baffle removed, new plugs, synthetic oil, new fuel filter and new paper air filter.

 

Oh yeah. Thats a scab stx BTW. Hey medic, where you from? I'm an intermediate in sc.

 

South Florida... I forgot I had a k&n drop in.

 

All stock 4x2 5.4L 2006 f-150 I used to get 17-18MPG no matter where I was.

Now I get 14.5.
Went from 225/70/17 to 247/70/17
93 perf tuned Gryphon
Aem CAI

 

14.2/18.7 mpg prior to mods on Shell 87 (E10) gas.

 

In an attempt to get a better idea of where I stand. Let me be a bit more specific.
My truck is an :
05 Screw 4x4 5.4L. 86K miles
K&N Drop in
Stock wheels and tires
Flowmaster muffler SISO (came with truck when I bought it)

 

04 F150 5.4L stock wheels and tires, Y pipe duals, hell bent leveling kit
City 12-13
Highway 16-17

Best i ever got on highway was 20.7. cruise set at 58 mph. but thats just to slow for me.

 

I average 17+mpg on 60/40 (hi-way/city) driving using Shell 87 (E10) gas and 20+mpg on hi-way with cruise at 70 mph.

A best of 21 mpg on hi-way using Conoco 87 100% gas.

 

I was getting around 15 MPG back when everything was completely stock and boring. Now I get around 17.5 during the summer, but I'm sure it's going to drop to around 16.5 when the winter blends are released.

 

I do about 14 city, 18 hwy. 5.4 with k&n drop in. That's it.

 

Got 14mpg on my first tank last week.
