The one thing that did amaze me with this truck is the fact that I get between 16-18 mpg. It's a 94 F-350 7.3l non-turbo DRW Dump Truck with 56,000 miles. With 2-3 tons in the back, it gets about 10-12mpg which is still impressive.

milegae

I've got an '89 F-250 manual, the motor blew a few weeks ago, but i used to consistently get 13-14 MPG around town. On a trip from NY to Iowa last spring I got 22 MPG empty on the way out, and 20 MPG with a little over a ton of parts in the back on the way back.

After the motor was well on its way out I managed 9.4 MPG on a trip to Ohio pulling a 24 ft gooseneck. dropped to 8.9 MPG on the way back with a 2 ton farm implement on the back. I wasn't babying it either, I had my foot in the floor the whole time. The truck had become pretty gutless and I had low compression from bad rings.

I have an 03 F-350 dually which I get a consistent 18mpg. While towing a 6k lbs trailer that drops to 14mpg. On a straight highway run with no trailering I get 21mpg.

My secret is that I keep my right foot in check. Seriously, you know the biggest single thing I did was to switch to a good street tire instead of an AT or a mud tire.

One surprising thing is that when I run B5 (5% biodiesel and 95% petro diesel) in the tank I loose about 2-3mpg. That I wasn't expecting. I'm going to try B20 and B100 and see what happens to my mpg.

I got a 96 F350 Crew Dually 7.3 IDI. I average 15 MPG. No mods done to it. I plan on if I don't sell it to get 4" exhaust and hope to find a ATS or similar Turbo to put on it. ANYONE CAN YOU HELP ON THE TURBO>
