I've talked to 4 of my buddies (not in the business) who own Dodge diesels and they all claim to get 18-25 MPG. They range from 2005 3500 to 2010 2500.
I currently run Ford's and when they pull a 20' trailer with three Z-turns and other small equipment, I am getting an average of 7 MPG. My mechanics have looked at them and says eveyrthing is functioning and not sure why the mileage is bad. My drivers says they dont idle excessively. They got to 2-4 commecial sites a day.
The fuel bill is killing me!!!! Please help!!!

They must be kicking the piss out of them at all times.

I dont think so. I drove one of the trucks a few weekends ago to help a friend move and do some other stuff. We started Friday morning and finished Sunday night. I kept track of the MPG and the I got 6.4 MPG...

Ok, i have a duramax diesel and pull a 18 foot enclosed with 2 z's and a walkbehind, and its nothing but stop and go in the city.. Last fillup i averaged 11.9 mpg. I can get 18 city drivin if i am dead empty and light footin it below 2000 rpm.. Im sure the dodges can get that mileage too empty, but no way pullin a trailer like mine. Remember diesels get alot better mpg, but also are alot more expensive up front and to maintain. Its kind of like a pay me now, or pay me later kind of thing. I personally love the diesels cause they will last forever if you take care of them and the resale value is awesome! Oh, not to mention they will pull anything.

I forgot to mention, they are all diesels...

Is it a 6.4? I used to have one and it would get 10mpg empty or pulling 10,000 lbs. If I get another diesel it'll most likely be a dodge with a 5.9 or a highly moded 6.7.

With a 1999 dodge 3500 5.9 cummins manual. I get around 14 to 16 towing in the city. Highway without a trailer 18 or 19. All stock but a EDGE controller that lowers the RPMS at highway speeds. Hopes this helps.

My 06 Dodge Dually will get from 12-30. It will show 16-34 on the computer but its 4 gal less than that at the pump. It depends on now I drive it. It got 15.2 pulling a 38' fifth wheel camper in the Black Mountains. But you have to run 55 at 1450 rpm. Had a guy with me who has a new Ford the other day. And I showed him what it done by rpm's he couldnt believe it. I wish it had 3.55 gears its got 3.73. My brother-n-law has 3.55 and he gets 22 pulling his race car trailer. Good fuel also make a difference. Pulling the lawn trailer I have been averaging 17 every week so far.

Have a '99 that can squeak out 16-17 around town pulling a 20ft enclosed with two ztr's, and an '03 that is 13-14 with the same trailer. Both auto but the torque converter locks up at 28-30 mph on the '99 which makes all the difference

Those inline Dodge Cummings diesel engines build higher torque in lower RPM's than V8's diesels,makes a big difference for towing big loads.Other factors that contribute to higher fuel mileage,reducing in transmission internal parts rotating mass,O/D reduction %,tire size,manual/automatic,etc,etc.

I dont have mine chipped either. Now that good gas mileage is on level flat ground and at 55. Anything higher than that and it goes south in a hurry. We use to go to alot of NASCAR races everywhere. And my wife just hated for a Ford or Chevy to pass me because she knew what was going to happen. Just loved to blow back buy them in the hills. Now this aint bashing Ford but going to these races we seen more newer Fords along side the road with the hoods up. Never seen any of the older ones just the new Super Duty ones. And this was in the mountains where they had a strain on them.

2011 ram 4500 it says I get about 13-16 mpg empty that drops to 9-10 when I'm towing and got a full load of grass. I got a 99 ram 3500 with the inline 6 diesel and get similar mileage. I wish it was better but it beats the hell out of what my old boss got with the 460 in his 96 f350 4-5 mpg and that's being kind I think it was even worse then that.

The fuel bill is killing me!!!! Please help!!!

why is the fuel bill killing you? is your fuel bill for the year above say 6-10% of gross. if it is I would look into why. I know fuel is a concern but so are a lot of things.

Here, fuel is a concern but not really. it is a percentage of gross but it is at the lower end of percentage of cost of business.

My 5.9 Cummins puts 500 hp to the ground and averages around 15 mpg no matter what kind of driving im doing. The 4.10 gears help around town but hurt on the highway.

I have a 1991 dodge with the 5.9 cummins I have gotten as high as 24 mpg on the highway empty. I've also gotten 13.5 pulling a 30' fifth wheel. I don't know of any other diesels that get as good of mileage as the cummins.

06' Dodge longbed, gets an average of 16 empty city and that quickly drops to around 12mpg when pulling around 5,000-6,000 pounds. Pulling my 1500# boat last weekend to the lake and back we saw 18.5mpg but again quickly dropped once the work week started back up again. I know for a fact that a gasser truck of the same size would be getting around 8-10 mpg so its not great but better than a gasser. Lately she has been sucking a little more fuel as the AC has been on full blast with these 100 degree days. This fall I will be getting a pretty big camper to pull behind her with all highway miles and itll be interesting to see what kinda mileage I can get with a big load but all cruising and no over populated city traffic.

Mine is an 07 5.9 liter mega cab dually diesel in the pic. I am getting 25mph without a trailer and around 17 when pulling. It has a 6" lift and mud tires.
I have a diable tuner, an afe stage 2 cold air intake, and a straight exhaust with an aeroturbine muffler (not so loud), I only spent around $1000 for the upgrades, but we installed ourselves.

You can tell who has flat ground and who is going up and down hills all day just by the mpg they post its never ending hills around here.

I have a 2008 cummins 3500 and my overhead usually shows about 7. That's pulling a 10000 pound machine a lot of the time. And I'm in southern bc and it's all straight up Nd straight down.
