I have a 4x4 and my mpg avg around 12-13 in the city with only 5600 miles. I know it gets worst than a 2wd, but by how much ??

I also have a new '05 CC/SB, and I never see less than 17.5 is city, with a bit of doggn' it and leaving it idle when I go into some stores (using the second door remote).

That's with the DIC though.

Don't trust your DIC. :eek: To get accurate MPG results you gotta do it by hand.

I've got 6k on mine and only get 16.2-16.5 to & from work, all city.

You are basically at the same elev./temp as me, I'd guess you are actually

getting a little less, but who knows.

04.5 lly ext/sb 4x4 avg 17.5 - 19 mpg 21k mi

2 Mpg

I have both and the differance is trivial.

From past experience and what I have heard the mpg difference between 2wd and 4wd should be very minimal on HD diesels. I would think this is because these trucks are on the heavy side and the engines have so much torque.

That's what she said.

:bounce:

I have 2004.5 2WD. Get about 16.5 mpg mixed driving calculated by hand. DIC usually shows about 1.5 mpg higher.

Mine is a 4X4 Crew Cab mine mileage was about 14-15 the first 5000 miles I now have 15,000 and I get between 17 to 18.5 depending driving locations.

What cit said! ):h Why do they even make a 4x2 diesel dually! 4x4, NO LIMITATIONS! JJ :)
