fuel mileage ford vs dodge

[PSD01350]

I have some questions on fuel mileage on 05 6.0 psd vs. Cummins 24 valve common rail while pulling 10-15k lb. Please comment your thoughts. I'm gonna pull a 48 ft flatbed gooseneck. I'm a diehard ford man.....but my friend says cummins will get way better fuel mileage. i want your opinion!

Our 5.9 gets better mileage than my 7.3 and my old 6.0. Not saying that is always the case but that was my personal experience.

My truck per signiture puls the RV like a dream. Got as high aas 16MPG on flat ground

I am getting around 15MPG a comparable dodge gets about 17MPG. I don't know about 6.0 Ive heard anywhere from 9mpg (with a screwy computer) and up to 20mpg (with the same screwy computer) I have never owned one. I don't think it would be significantly better but thats just my 2 cents.

Cummins will generally get better mileage mainly because it builds all of its torque at such a low RPM so it doesn't have to rev as high. Tire size, gearing and other things will also change MPG's.

I owned a 01 vp44 pumped cummins with 4:10's got 14 all the time empty loaded flat hills didn't matter. MY 94 7.3 ford has 4:10's does the same both trucks manual trans 4x4 i got rid of the 01 for a 08 dodge 6.7 has 3:42 gears manual gets 23 empty does 12 loaded so depends mostly on gears i think.

2007 and down cummins without egr and dpf are ganna get the best mpg no powerstroke can get what cummins gets loaded or unloaded.

i dont think ive ever been able to keep my foot out of the pedal long enough to get a good milage while towing (~9k) 10-12 seems like my normal, im sure 14 or so if i could keep my foot out

[larry782]

The only good powerstroke i had was my 99 7.3 powerstroke i got around 20mpg unloaded and about14-15mpg loaded my 6.4 only gets 15mpg empty
