2013 duramax performance
Took delivery on my 2013 Durmax/Allison the end of Nov. 2012. I was wondering what fuel mileage others were getting. I have about 1200 miles on it so far and have not pulled the 5th wheel yet. A trip from Denver to Colorado Springs, running empty, netted 20.3 MPG. Around town I am getting about 15. Hope to see it come up a little bit.
I really hate the TWO emission systems. Seems like a lot of overkill.
Thanks for any responses.
