06 qcsb 4x4 manual 4.7 34gal... 480 miles, a lil over 15mpg... fill up with 32 or so gallons

 

05' 2500 with the hemi, QC, SB, see signature for mods, 1/2 highway 1/2 city, with 87 tune I would get 260-280 per tank (35 gallon tank with an average fillup of 28- 30 gallons), with 91 tune (usually 93 octane) I get 330- 350.

 

I usually get 325 miles per tank city.
I have hit 400 miles on the highway.

 

375 miles per tankmixed highway and city, 411 miles per tankjust highway.

 

05 QCSB Hemi with 35 gallon tank the best i got was a little over 500 miles on a tank and the needle was just below the 1/4 mark. Usually get around 350-375 a tank mixed driving.

 

34 gallons, 320miles

 

According to the overhead, my DTE on a full tank is about 385 miles. That's usually good enough to last me a full month since I use a different car to drive to work.

 

on recent trip to houston about 550 miles from where i live i went 400 miles on about 3/4 of a tank of gas before stopping for more fuel. 26 gallon tank computer says i was getting about 20 mpg. on the way home which was uphill i only got about 18.5. highway mileage of course.

 

Okay so the best I can determine is if you are getting 400 miles from a tank of gas you are doing pretty good. Also it seems that whether you have the V6, 4.7L, or Hemi they all get about the same mpg.

 

502 miles, 34 gallon tank, 16.2mpg, going 55mph.......
