For those that STILL refuse to listen, Google "REAL WORLD fuel mileage (insert your year here) Cummins Dodge" and read until you pass out. Loaded or unloaded, you'll find it all.

Even my '02 Cummins was not that great on fuel and I had every trick in the book on it:

60 hp Edge

3.55 gears

and 285 rubber.

Best that Cummins got was 16 to 17mpg empty and hell, I'm getting that out of my current 360 Mag with electric fan and dual exhaust with the catalytic converter cut out.


I just bought a 2003 2500 4x4 long-bed with the HO (305hp version) 3.73 gears, and drove it home from Oklahoma to Mid state PA empty. Lowest it clocked was 18.9 and highest was 21.2, all hand calculated... the over head said 20.5 to 21.5 for the most part, so not too far off. Lowest reading was actually the flat lands section of I70 & best was the 300mile up/down hill section of WV & PA shruggy

This truck still has a bone stock cummins,(no edge or even CAI) and still has the original factory exhaust. But it does has 285 rubber on it which seemed to knock few rpms off. 70 on the GPS seemed to be about 67-68 on the dash speedo.

Sure beats the 11-13mpg I get out of my old 98 Ram with a near dead gas hog 360 in it...
So I'm more than happy. boogie
