I recently purchased an 07.5 3500 srw 4x4 longbed with the 6.7L.
My milage sucks it is at best 10 to 11 mpg. The truck has 2000 miles and the fuel bill is killing me. Is this what I should expect or will it get better. this truck has 3.73 gears

Hey there good buddy,
I purchased a 07.5 with a 6.7.g-56.2500.My milage is
about 15.0-16.0.I have found if you keep the tach at 2.000 rpm it does the best.Even though the engine is at 2k it still has gobs of power.
