Fuel Mileage.

I pretty much average around 15 and don't do much city driving.

 

I just got 18.3mpg!
And here's the proof


This was done in 2hrs and 20mins for an average of 60mph. The first 30min were into a strong headwind that caused my instant mpg to show 10-11!

My biggest change to the truck recently was adding a plywood bed cover, I guess that my 8ft bed had a lot of drag!
I also have my Edge adjusted to drop into O/D 3mph sooner, running larger tires (speedo is off 4%), timing adjust 2.25*, and ran midgrade (88.5) the last 3 tanks.

 

I voted 16-18. With my 4.6L, 3.55 ls, stock tires, Gotts mod and new custom 87 perf tune on the Gryphon.
I was getting about 13-15 when I had my WASHOOBI installed with custom tunes. My truck gets much better mileage now without a CAI.

 

Wtf is a WAHOOBI ? Your mpg is pretty common either way, how fast are you driving on the highway?

 

13-16 mpg.

I knew what I was getting into when I traded in my '05 Hyundai Elantra with a 2.0 4 banger and 5 speed for my '06 F150 4x4 with a 5.4 v8.

I just wanted a truck. Blame it on country music I suppose.

 

i average 16 in my 06 4.6 with stock tires and pretty sure 3.55 since thats most common in them. and that was a year ago when i was freeway the whole time maybe three block of city driving

 

For one, that's all city driving. And a washoobi is : F150online Forums - View Single Post - Question about getting a programmer..

 

Thats good for city driving!

 

I've been getting a steady 16.6-17.0 the last two months. No lie I don't know why. But I'm definitely not complaining

 

Consistently get 10-11. 37s, 4.56s, exhaust, CAI. Mostly mountain driving at power robbing altitude.
