2008 fuel economy

[Performance Oil Products]

yeah, The big part is your chip......You Need One. The intake, exhausts and programmer got me a little over 5 miles to the gal.

The 7.3 detuned from the factory compared to the 6.0. So everything you do to it improved power and milage

Dang guys!!! I'm happy if I get NEAR 500 mile/tank!!! And usually I'm getting about 400-ish before I fill up. Though...I'm at about 400 right now with about 1/4 tank left....maybe I'll get near 500!!

I get about 450 on 38 gallon tank but I never putt

I am happy if I see 550 on a tank.

the most i ever got before chipping was 15 and that was doing 95 miles an hour to California. In the city i had 11. now i get 15 in the city with my chip!

dang guys i am still only getting 13.2-13.8 mpg, just last week i got 400 miles to a tank, i WAS stoked, then i filled up and got 28. something gallons (most ive ever put in it was 26 gallons. im up to 76k,so at first i thought i got better mpg bcuz i used my regular 4oz of Ford booster, AND 4oz of Standayne, AND a buddy gave me some Cat injector cleaner at 4oz,,,, what gives!!!!!!

I am currently getting about 13 MPG around town and got a little over 14 MPG on the interstate on a 500 mile trip I took last week.

I thought this thread was about the 6.4L fuel economy. It makes it difficult when I have to wade through 16 posts to find the 3 people who actually have a 6.4L truck. Yes, we all know that the older engines get better fuel mileage. Maybe the 6.0L and 7.3L forums would be a better place to discuss the fuel economy of those engines...

2000 was lifted, 35s, Gale Banks Stinger kit, 4x4, CC, auto.

2008 is stock-4x4, CC, auto.

I am getting 13 miles to the gallon around town empty (no towing or load). I have 1945 miles on vehicle. I think a lot depends on how heavy your foot is on the pedal.

08 F-350 SWR 3.73 gears and crewcab with 600 miles on it and 250 lb in the box and I did 17.4 miles per u.s. galons at 55 to 58 mph on cruise on a 253 mile trip. Hope it gets better.

08 250 crew FX4 SB with 3.73's. 300lbs in tool box and about 400lbs in tires in the bed. Have 700 miles on it and am getting 15mpg in heavy traffic. Have not seen the highway yet. But, so far am VERY pleased with the economy. $2.75 for ULSD last week. WOOHOO!!!
