Interstate 65mph....20mpg....70 mph......16mpg
In town 18.5 to 20mpg
Puling trailer with large rear gate 14.5 mpg, loaded or empty

 

18.5 empty and 12 to 12.5 at 19,000 lbs GCVW

 

I get around 18 to 19 unloaded around town and 22 unloaded on the interstate.

 

I get about 19-20 around town, haven't had it on trip yet but the guy I bought it from said he averaged around 20. Still stock, waiting for more money to do minor bombing.

 

Since I bought my rig back in May, I’ve been driving it like I STOLE IT! To date I am getting around 17 MPG consistently. I drive about 75% highway as often as I can at 80+ mph. Oh yeah I am still stock, for the near future.

 

When truck was stock i got 20-21 on the freeway, 16-18 around town. since i put the bigger compresser housing i've lost a couple miles per gallon off each... not to happy about it, but thats the price you pay i guess.

had an edge ez on it for a little bit and it does throw off the mpg calculator. it was telling me i was averaging like 22 or better on a tank. i'd like to know what its doing to throw that off if somebody knows.

 

Only chance I've had to measure "all interstate" was between Columbus, Ohio and Gatlinburg Tenn.. On BP Supreme @ 70 mph (1900 -1950 rpms) I measured 20.6 mpg, coming back home on Texaco at 65 mph I measured 19.8 mpg. Around home I usually get around 17 to 18.5 mpg avg. I sure cant complain.

I GET...CHECK THIS.....420 MILES TO A GALLON!!!!! That is when gallon is loosely defined as a tank..... Apx 15.2 mpg. That is 33" tires with a box. Doesn't matter if I ran the Bully or the Edge....still the same......BUT not to bad considering that my old '86 with a 4.9L I-6 (Gas) and same running gear got me 8mpg!!!!! The old Dodge will run circles around it as well....LOADED!!!!!!!!!! MAN i love Cummins. ;D
