I have a 2004 f250 with around 39,000 miles. when i first purchased the truck i took it down to gulf shores ala. from Indianapolis, In. I was getting about 23 mpg!!! No kidding. Normal driving i would avg 18mpg I then took the truck in for a service bulletin update which they installed a new metal tube on the cooler and reprogrammed. any way since then I get about 17 mpg avg and have installed a superchips flashpaq programmer. What else can I do to get better mpg and with little cost. Also what do most other members get MPG with there 6.0L . Thanks :icon_ford::dunno:

welcome to the Org bud... most will tell you that 17mpg is very damn good.... also is this hand calculated?

lil cheap things you can do to get better MPG is keep your filters clean... this includes your air and fuel filter... make sure your tires are properly inflated... the biggest factor is your right foot...

now if your willing to spend some money a 4" TB exhaust will create less restriction esp if you elliminate the cat and exhaust... and i would highly suggest a custom tuned SCT xcal 3 with an econo tune....

let us know if you have any other questions and welcome

I would also look into putting a intake on it. If money is tight, I would custom make one. Not very hard, napa sells long and round filters that have a 4 inch opening!

That's a better idea than a Foam filter. my 2 cents. I hate foam filters.

I just went down to North Carolina and on the way down with the cruise set at 70 i was getting just under 21 mpg. I then had to hit the hills of WV and thru Va back up to New England (going pretty good as i had to get home to go to work in the am) I was getting 19.8
I didnt think that was to bad at all. Oh yeah all stock too

Box stock, with a 06 F350 CC/dually, I'm seeing around 16-17 mixed city/hwy, if I don't count the steep hill I have to pull coming out of my house, it's around 18. Back in the cheap gas days, when I wasn't paying attention, I was seeing around 12.8. That's a 30% improvement that comes purely from adjusting driving style.

The big one was the right foot. Easy on the starts, never over 10psi boost, and if you see a red light 100 yards up, take your foot off the gas and let it coast. Also adjusted my drive to miss rush hour traffic, leave half an hour earlier, leave work half an hour earlier. That really helped. Funny thing is, I timed my commute with my slower driving style. Carefree, it was 28 minutes. Careful, it's 32 minutes, and I save about a gallon of fuel. Let's see, $4.50 for four minutes, that comes out to around $70 an hour. Pretty good pay for driving slow.

On the highway, drafting a box trailer semi is good for 2mpg @ 70. I don't drive to lunch any more, walk instead. That helped some, cuts down the city driving. Just think about the money in your pocket, that'll put a smile on your face.

I think someone should come up with exhaust stacks shaped like a dollar sign on the end. When they blow smoke, it will look very realistic.

save fuel

I like that $$ on stacks.well I just did a EGR block-off on a 06 tow rig and the tow truck driver said it was the best thing he put on? and he said he gets good fuel savings now and power.I dont know,it was a pain in the *ss and 12 hours to put on.first one i did.It came from liberator performance.now he wants to put a WW wheel in his 6.0 turbo,will it fit? I have the WW but what will it run like?

I saw no difference in mileage from exhaust. When I first got the truck, I installed DJ's economy tune and averaged 20.5 on my first trip running on the almost completely flat I-10 going 75 or so the whole time. After exhaust, I didn't see any real difference. I just went to Florida from north Kentucky and got 19.2 over the trip down with the bed full of crap and carrying 3 people. I got 15.7 on the way back with even more in the back and towing a VERY overloaded 12' Uhaul. :)

I've never seen 16 or 17 in town. More like 14. I usually average high 14s to low 15s mixed. I sure wish I had one of the trucks that did that well.

keep the truck under 2000 rpm to save money

if I drive no faster than 60 I get 23 mpg
driving to work 30 miles through Minneapolis I average 18mpg in town and on 70mph freeway

for a crew cab truck I think thats good or go get a ford escort 40mpg+

Just the other day I hand calculated my mileage over the last 1,100 miles or so and I got 18.63.

I had noticed that I seemed to be getting more miles on the odo between fill ups lately, but didn't realize I had been doing that well. I'm certainly not used to getting mileage like that outta my truck, but this is the first summer I've had it.

Just to double check my calcs, I figured my mileage over the last 600 miles. It came out to 18.32.

I'm anxious to get an SCT with an economy program that also turns off the egr programming. Right now I'm running with both ends of the egr cooler plugged on stock programming, but I think the truck is defaulting to lower programming even though there's no SES light.

Heck... my wife's minivan only gets 20 - 21, so I'm quite happy with my 18! 95% of the last 1,100 miles was unloaded at speeds below 65mph.

Well I'm in the catagory of being pretty disapointed in the milage from my truck as well. I did about 16.8 on an 850 mile round trip this weekend.

Out bound I saw about 16.3 running 80-85 on the Interstated and then 70-75 once I was on the 2 lane. Cruise pretty much the entire way.

On the way back same speeds, though I saw a North of 18 on the interstate following my buddies 5th wheel a little closer then most would like.

In town I've been seeing 13-13.6.

I've been hand calculating every tank, and the dash meter and my math have been pretty close.

Anything over about 75, and the mileage falls on its face. It would be nice to cruise 80-85 and still get 35-37 MPG like my Civic, but I've just had to learn to slow down. I usually run my truck about 72-73 on the road and get 19s on average.

I was reading an article in Diesel world (Project MPG) the other day,It said they went from 17 to 23.?? mpg with a few mods... From what I have been reading here, sounds like they are full of it. I would post the link but I don't know how, here is the address to the article. Project MPG: Part III
When I get back to the states I want to do something similar to what is in the article. I already have the Quad Xzillaraider installed , exhaust waiting to be installed, I just need to do my intake, I am thinking about the AEM DryFlow.
What do you guys think? Is the article full of bull and is the AEM any good?
Thanks
Kirk
