What gas mileage are you guys getting with the 5.4L V8, in a 4x4 with the auto trans.

I was more looking at a truck with 3.73 gears, in the 4DR cab design.

Thanks for any and all info!

 

I am getting mid 13's that is with a mix of city and highway. The only mod's I have are the airaid intake tube and superchips tuner. I want to add an exhaust before too long.

 

Wife's '06 Expy 4x4 (same drivetrain as F-150: 5.4, auto, 3.73, etc.) = 13 and change on avg. It may get close to 17 on interstate trips, but very seldom.

Dad's '05 4x4 Supercrew = same

Just for comparision: My '99 5.4 4x4 (I think I have the 260HP version) = 14 and change, but can get 18 on interstate.

All vehicles are stock.

Ford touts the new 3V 5.4s were to be more efficient and they are, but that does NOT mean better fuel economy. They make a hell of a lot more power, but maintain similar, if not slightly worse, fuel economy. Decent tradeoff IMO.

 

I have a 2007 Screw 4x4 5.4 and I get around 14.2 in the city and 18 to 18.5 on the highway

 

My dad's 04 gets 16 with mixed city and hwy, and can easily get 20 mpg on hwy trips. This was checked on the read out in the truck and hand calculated many different times. All it takes is easy acceleration.

I drove it on a 100 mile trip w/out a/c and cruise between 50-55 with light acceleration and got 24.6 MPG!
With a/c and decent acceleration doing 60mph it can get 20 without much trouble.
It is a 5.4 screw lariat 4x4 with 3.73 gears.

 

nope, actually, the 2004+ trucks weigh more than the previous generation. they got more power, and at least 500 lbs more per model than previously. <b>my 6,000 lb truck gets the same MPG as the 5 smaller SUV's that preceded it</B>

2006 SuperCrew FX4 with 5.4 and 3.73 gears
City: 14 ish MPG
Mixed: 15-17 MPG
Highway: 18 MPG at minimum, I've pulled 21 MPG before

See signature pic for mods.

 

i average 14 MPG, and i really only get to drive in a city type setup where i live (for lack of roads). im running 325x60x18 tires.... cant wait to get the lift installed, but then i wont expect to get any better than 11-12 with the 35's.

 

Man, some of you guys must be heavy on the pedal or something.....

My '07 is bone stock, and I average 16 around town, and 19-21 on the freeway.

+1 on my 04. Except I have a K&N drop in filter and an Edge programmer on level 2...

Granted the mpg hasn't changed with much if any with either modification.

I 'm averaging 19.5 mixed mpg.

 

Just took mine on a 200 mile trip last weekend. I have a 06 Lincoln Mark LT 5.4 4x4
The terain was flat. I did 100 miles with the Cruise Control set at 65 mph and the
read out was 20.9 mpg at the end of the 100 miles. The next 100 miles, I had the cruise control set at 75 mph,
and the read out was 19.1 at the end of the 100 miles. Average around town is 13.9 mpg.

I think for the size of this truck the economy is great

 

I average mid 15's in miy 2004 Screw.
Put it on the road with a small trailer and the numbers shrink to mid 14's.
