2012 Dodge Cummins mileage?

Looking to trade to a new dodge or Chevy Duramax. Wondering what kind of mileage to expect out of a 2012 Cummins EGR engine?

If it's anything like my 2010, you can expect no better than 17 mpg (Canadian gallon, which is about 18% more than a U.S. gallon), and that's running a 2500 4X4 empty with 3.73 rears. This is my fourth Dodge and I've always been satisfied with the Cummins until now. Not saying the engine isn't good, it's just what Dodge has to do with this engine to meet emission compliance.

Have the 2011 3500 4x4 DRW at work and it rarely got 10mpg while towing, usually in single digits. The range with a full tank while pulling a trailer I get is 450km. Used to have an 07 megacab 2500 that was the 5.9 and it was averaging 20mpg combined. The egr and dpf are killing fuel economy!

2011 GMC Duramax...flying down the highway home from Saskatoon a couple weeks ago @ 130 km/h ; instant economy reads 12.9 L / 100 KM which is just shy of 22 MPG (imperial).

Glad to see some happy Chevy owners. What about urea consumption?

I really like the Longhorn Laramie Dodge interior. If I had not seen this I would not think of a Dodge.

I bought a 2011 Chevy 2500 gas last December and I really miss my past diesel pickups. Put 22500 miles on it in less than a year and figured I might as well trade.

I guess we should've bought the duramax. We bought a 2011 f-250 with the 6.7 last fall and have hated whats under the hood since day one.. On a good day you have to get 12 mpg unloaded. loaded a v-10 gas would beat it for mileage

My 2010 with a stick shift and (I think) 3.73 rear gets 13.5mpg around the farm, and on a long trip it will get 16. No different than my old 5.9L Magnums, except the Cummins will pull a fertilizer trailer without breaking a sweat.

Maybe after I've got a couple more years on it I'll void the warranty.

2010 Dodge 3500, 4X4, 6 Spd Auto , 3:73 rearend = 16.65 MPG (CDN) for 1st 80,000km.
Once out of base waranty - delete kit for the EGR, DPF , Muffler ,an AFE cold air intake and a programmer to keep the warning lights at bay $1,457.00 later and running 23.72 MPG (CDN) for the 1st 37,000km ,
Very little noise difference compared to stock. Went through a roadside smog check and passed.

We also have a 2011 3500 Ram cab and chassis running DEF and it get's close to 20 MPG (stock)

I know it's a ford but traveling to BC got 25 mpg imperial with our 2011 F350 diesel measured by fuel used and kilometers driven. Computer said 12.8 liters per 100 k which is a bit higher than actual use. Ford seems to have cleaned up thier act as far as fuel use goes. Time will tell if they have taken care of the reliability issues
