how many mpg do you cummins guys get

 

I get 20+ on the hwy unloaded. this will vary if it is very windy. I generally poke along at 60-62 and feather foot. It's easy to kill a couple mpg going 65 + or tromping on the pedal in tunnels haha
18-19 all around town stop and go. Again it is easy to drop 2 mpg hotrodding. But sometimes people just need to be smoked in. haha

don't foget this is a dually 5spd and I don't drive the front wheels.

got 15 pulling a 10k dirt mover and 20 with a 4k loaad in the bed

So you guys are able to pull of 20 mpg? Is that the HO or not? If not what does the HO get. Im gettin 11 in my 360. If I can go to a diesel and get 20 on the interstate I'M IN.
