I'm an owner of a 06 1500 with the HEMI, and I probably average about 10-12mpg with my driving (mostly in-town driving, usually go 5 over speed limit). I was just wondering what kind of gas mileage you guys with the Cummins get? Is it any better? Worse? please let me know. Oh and almost forgot, I'm usually around $100 when I fill up, what about you guys?

 

i get 24-26 undloaded with 35s and 700+HP when i dont hot rod her.. worst i have gotten with a load is 14 but i was way way weighted down

 

Texas's numbers (if they are for his 05) are not typical.

06 Ram 3500 CR 5.9 Cummins - 17-18mpg.. mostly highway. I've been seeing 20 a little more often in the last while.. not sure why... might be the engine is broken in. Numbers are verified by hand, but my o.h. computer is within 0.5mpg typically.

 

For my 05 but that's at 55 I get 20 at 65-75 depending on road and weather

 

Stock 07 5.9 MegaCab, 14-17 on 32's 3.73ratio hand calc. Usually just over $100 to fill up when its around 1/4 on a 34gal tank.

 

"06 2500 CTD stock tires emtpy maybe 13 highway, pulling trailer 10mph highway and city is around 10ish.

i have Edge Juice, kn air intake, and 5" exhaust from turbo

 

oh yeah at these prices for fuel at 1/2 tank was 74 bucks... ouch

 

99 CTD.. before oil change, fuel filter, schaffer's fuel treatment, and K&N filter I was getting 14.6 mpg city

after the above changes: 19.4mpg city

 

04.5 2500 5.9 ***. Banks six gun and top loader. When I drive from Los Angeles, CA to Port Orchard, Washinton to vist family I travel light with just luggage and a few gifts at 5 over the speed limit. I get 21.5 miles to the gallon. When pulling my race car to and from Culver City to Ventura and back at 58 MPH I can get between 18 to 18.5 MPG. If I tow over 62 MPH the figures drop fast. These figures are by hand. The computer is off almost 1.5 miles to the gallon. Does anyone know how to fix that?

 

my 02 only has 40k on the new engine so not really broken in yet. If im hard on it I see about 14mpg if im easy on it doing the speed limit i get about 18. I have 4.10's tho so highway miles could be better. 70mph is 2,300 which is pretty high if you ask me. My buddy has the same truck with 3.55's and he see's 20. I spent 102.00 to fill up from 1/8 a tank which was 24 gal.
