I have an 04 f150 crew. I was reading the discussion about gas mileage on edmunds and just had to respond to this one. I've seen the programers before, didn't think that much about them, in terms of a considerable increase in mileage. What type of programmer did you use, where did you get it and what did it cost you. My 5.4 is getting me just under 15 in mixed drive. It PO's me, especially when I hear that me dad (with the same truck) is getting 20 on the highway. I have the throttle body spacer, but its not giving near what you're claiming. Makes me skeptical. Can you provide more data? thanks.

20 MPG!? Is he pushing it? I just bought an 05 250 4x4 5.4L, and I'm lucky to get 13 mpg. After 1100 miles (over 90% of which are hwy), I'm getting btwn 12.5 - 13 mpg (never over 70mph or 2500 rpm). Looking into a KN air intake, but can't find one for an 05 anywhere. Maybe I'm better off parking it for a while with gas prices around $3/gal.

I'm not kiddin' you!! the lowest that he's had on a tank of fuel is 15.7 mgp. He drove over 200 miles out to Albany, at 65, and got 19.8. Drove back, at 70, and got 18.5. He told me that he was doing fire police work one afternoon, and left the truck running for 3 hrs. while he was directing traffic (Dad's in his mid 60's and needs his AC) on that tank he was all the way down to 15.7. I've seen the receipts. He does a lot of country driving, but that's incredible. My 04 isn't touching that. I'm with you. Park it. It's a hell of a price to pay for something that just sits, though. My minivan it getting the lions share of the family travel. My dealership told me not to run the KN air fliter. It leaks and allows dirty air through. If the air mass sensor goes with that air filter in, they won't warrenty it. Just some info I've learned along the way.

So when should my mileage start getting better? I haven't gotten better than 13.1mpg, and I have 1300 miles on my 05 250 5.4L (over 90% of which are hwy miles). The K&N issue with the air filter seems standard for a dealer. If you don't install the filter (any filter) correctly, it will allow dirty air to pass through. I had one on my 99 F150 4.6L, and after 48K, I was still getting 21-23 mpg hwy (a big improvement over the 18-20 mpg hwy w/o the K&N).

Man, you have to be kickin' yourself for getting rid of that '99 w/ the smaller block. I went the other way, though I'm not entirely satisfied with the mileage. I'm got rid of my 02 Avalanche with the 8.1 liter. 13.1 looks pretty good when you compared it to that thing. I don't know what to tell you about the prognosis for when you mileage will improve. My guess is that it won't...under present circumstances. Sorry. On this tank, I've been backing way off the accelerator and it seems to have made a difference. City and some country driving, no highway. I'll let you know. I try to ask guys, that I see with the same set up as me, what they're getting for mileage. Most don't seem to know. Most out of fear, denial, etc...! I e-mailed a buddy of mine that is an engineer for Ford in Detroit. he works mainly on brakes, suspension, etc. for the SUV and truck divisions. He had a pretty good laugh over my request for "great" gas mileage on that ship that I was driving around. If I wanted good gas mileage I should have purchased a Focus=:( Not going to haul a lot with that. Not even the kids. I e-mailed him back, told him to cut out the smart remarks and talk to the guys in the engine department. I'll let you know if I hear anything. Hang in there, man, we're all suffering.

I have had my truck for almost 2 weeks now and seem to be getting 11 mpg around town and about 16 on the road. The sticker said 15 mpg around town and I was expecting to get about 13. Eleven is a little upsetting. I'm sure it will get better after it gets broken in--I hope so anyway!

I read this on another site. Pretend that you have an egg shell on the accelerator of your truck. Try not to break it! I've been doing this for the last 2 tanks. I've gone from 14.5 (f150 5.4L screw) to 17. It makes a difference. Remember to that the Ford didn't determine the mileage that goes on the sticker. The EPA does. I see gas going up again Thanks RITA

The thing is that I am not one to stand on the gas or anything. I could go slower, though, I'm sure. Looks like Rota may not disrupt things like Katrina did--that's good.

The reserch that I have done for the F-250 2005's the fuel mixture from km 0-2500 is very rich ( computer controled ) the 2501-5000km better. But not till 5001km ( around 3000 miles) does the mixture of fuel go to "as needed" for gas mileage.
 
I get 15-16 Hwy and 11-12 city, and that after I re-learned how to drive eg. the door locks do not look for almost 1 block ( slow acceleration) no fast starts...
 
My Ford Explorer 92 with 4 liter got around 25 Hwy and 18 city.. but I drove it fast too. Any one know the most optimal speed for the F-250?

"the door locks do not look for almost 1 block "
 
Wow, that is slow. I don't drive that slowly--and I'm not making any plans to start. I have slowed down--but not that slow. That almost seems like a safety hazzard for traffic behind you.
