What is the average fuel mileage on your 6.5 ?   I pumped 10 gallons of fuel this past Sunday and only got 130 miles out of em.  I did mostly stop and go driving and would get to 65mph only every once in a while.  No towing or loaded with anything.

I posted something on here a bit ago about my MPG experience with the 6.5 HD.  As it says in the post I get around 16 MPG unloaded weighing 8200 lbs or so with 5 speed manual

Due to recent budget cuts the light at the end of the tunnel has been turned off

loaded, I have yet to get single digits out of one. empty, the big HD chassis kinda brings it down, but mid teens with a 5 speed are average. drop it 1-2 mpg with the auto.
