What kind of fuel millage do you guys see with the sp. mannual? And on a cab and chassis? I'm getting 11 mpg. feeding cattle, and on the highway i'm getting 12 mpg. with my 07' F-350 powerjoke I'm not to happy with the millage as you can see. And thats hand calculated. I had a 2006 5.9 cummins then got this hunk of junk. I just hope the 07' 3500 C/C with the 6.7 is more fuel economical!!!

Thanks,

my 6.7 aint cab and chassis but it's getting 16.4mpg around town and about 18.1mpg or more on the highway

 

Infernoman, Does no muffler make any sound diffrence??

 

And how is that 6 foot tip working for ya?

' = foot
" = inch

:-)

 

well at first it didn't make a difference but now i have 3000 miles on it and sometimes it will have a really low and not to loud rumble then other times you just cant hear it at all but it's louder now than it was when i got it
