I think the reason the '04+ trucks get such absymal mileage in town is the weight. They're a lot heavier than the last generation of truck. It takes a lot of fuel to get them moving. On the highway the difference is not so noticable because the momentum issue is not as much in play. Once you are up to speed, it is more a function of air resistance.

 

average 14mpg, mostly country road driving with some highway mixed in.

 

00 4.6 355 gears auto airforce 1 intake rest stock. 72000 miles and orginal goodyears( with more tread to go) Mobil 1 5w30 20 to 21 miles with air on. Dont baby truck but drive 55-65 depending on the grade of roadway. 95% country 2 lane roads

 

06 SC, 5.4L, 3.55, and 20" rims/tires.......8.5k miles

Average about 17mpg mixed driveing taking it easy...

Haven't taken a road trip yet....But when I fill up and reset the MPG gage on short trips it measures about 19 up to 21 from 55 up to 75....

On a side note I have checked my mileage on every single tank since I have owned it and the MPG estimater has either been right on or no more than .3 off......If you keep your MPG selected at all times...You really curb your lead foot habits ALOT

 

I get 9 city 12 highway

 

4000 miles on my one month old 06 SC 4X4, 85 % hiway 15 % city. My average so far is 15 mpg with no mods. I also have the 20 inch Ford wheels but with one size smaller tire whichs results in close to the same dia. overall as the 18's with the 265's.

 

How does the 4.6L and 5.4L engines compare with gas mileage and performance with an automatic? Is there much difference in the 5.4 over the 4.6? I am down to a black with a 5.4 and red with a 4.6 all same features. The black 5.4 is $400 more with around the same mileage. I figure the 4.6 would be bad enough with gas but I want something that will get up and go. I get 31 MPG highway on a long trip / 20 MPG city/country in a automatic 1998 Ford Mustang GT 4.6 going at 65-80 MPH and would not have thought that the gas mileage would have suffered this much with a truck particularly on highway driving.

 

Get the 5.4.

I get 13 mpg all city

 

My 1987 F150 single cab/4x4/long box gets 11-13 MPG. Kind of sad I know, maybe someday I'll have the engine replaced by a diesel.

 

2000 F150 Extended Cab totally stock. I granny the heck out of it in town but ...

11 MPG !!!

 

You need a tuneup and to have some filters replaced. But as for me, I've seen as low as 11 MPG towing, or as high as 14.75 towing the same load on the drive home. Best MPG ever was 16, doing 75 with the windows down. Of course, my mileage is off due to my larger tires.

 

Full tuneup less than two weeks ago.

 

Has your fuel filter been replaced? How do you drive the truck? CIty or highway?

 

Usually, my mileage is pretty bad. Like 10 or 11 but that's because I drive only 3 and a half miles to work and the same home. Add the idle time when someone comes up to chat before we leave and, well, idling takes gas.

However! Two weeks ago I went to Michigan from Connecticut, AC working harder than the motor, cruise set at 75, and got between 21 and 22 MPG for the trip.

I've got an 04 2wd regcab longbed with the 4.6, auto and (I guess) 3.55's. I'm running 245r65x17 Bridgestones.

As I did two miles per gallon better than the window sticker said I should, I'm not complaining.

Flagship

 

Yes.

Almost all driving in town but like I said, I really granny it.
