My 07 dually duramax gets a verified average MPG of 11.9 AND that milage includes approx 1/2 of those miles are pulling 20+K pounds over the course of 40+K miles. If you're going by that dash indicated MPG you are not seeing the real MPG of the truck. OF course a big ol'Ford with talltires gets 21 MPG. Sure it does/did. I have dodge cummins friends that claim 20-30 MPG. Of course they stop to refuel each time I do so WTF???? One of us is wrong about the mileage we get.

Is yours a 07 or 07.5 with the new lmm motor? And yes my ford did get that mpg going down the road not towing but I had it chipped and had a aftermarket exhaust

Assume 100,000 miles of use @ 12 MPG(8,333 gals) compared to 100,000 miles @ 21 MPG(4,762 gallons).A 3,571 gallon difference. 3,571 gallons at an average price per gallon of say 2.50 gallon.That's 8,927.50 bux.You're STILL ahead by $11072.50. What's the beef????
 Even at 4.50 a gallon you're still ahead at 16,069.50 by $3930.50.
  I admit the duramax's get lesser MPG than the dodge or fords but not THAT much difference.

My Brother had a '99 F250 and it got 21 when not towing. It was one of the main reasons I bought my '02 Excursion. The Excursion is heavier and less aerodynamic than the truck. Yes it is possible to be worse, the air flowing off the top of the cab of a truck does form somewhat of a tear drop with the bed. The best I got was 19. I have now chipped it and added an exhaust. I never really got a chance to check it not pulling a trailer though. When I finally did, my wife reset the trip guage on me when she put $10 of fuel in. The overhead was reading 22, but it is not accurate. I have a couple other mods lined up, but not done. I picked up a regulator to put inline with the map sensor so I can go over 20psi without the computer cutting fuel. I will be removing the butterfly in the exhaust and opening up the housing there. I am considering ceramic coating the insides of both the turbine and compressor housings, the turbine to keep the heat in the exhaust and the compressor housing to keep what heat is in the housing out of the intake charge. I have not heard of anyone doing that, but it seems like a good idea to me.

The bugs were supposed to have been worked out of the 6.0, but I would still rather have my 7.3. The 6.4 has a less efficient combustion chamber design resulting in more unburnt fuel. That in itself lowers mileage. On top of that, it causes the regen cycle to run more often which burns additional fuel.

I am very interested to see what the new Ford built (vs. Navistar) 6.7 will be like. I have heard 800 ft. lbs. of torque. It will have a ground up designed 6 speed behind it that is significantly larger in physical size over the 4R100/5R110 behind the current engine. Basically they stopped tweaking it a little stronger then detuning the engine to what the trans can handle and went with a bigger box.

Master, I agree with the mileage, my 03 gets over 11mpg pulling my 17ish K lbs 5th wheel and I could easily pull another one behind it!! I love my truck and its got 140K miles on it too! These are actual numbers not off the dash, and believe me the Ford he got rid of would NEVER pull as much as the D-max! My buddy has a F350 and my 3/4 ton wanted 80MPH when his would BARELY do 45 in a head wind up a 3% grade pulling a much lighter 5th!

On a different note, did you gear the new truck, cuz if you didn't it will still pull well, it just won't get the same mileage!

Seriously check the gearing, with 35's you better AT LEAST have the 4.10 gear or you are throwing a ton of MPG out, my brother has 3.73's and he gets like 2-3 mpg less than me and he is towing a 7000lb BABY trailer and I have the beast!
