I completely disagree with the last thread. 07.5-2010 Duramaxs will get less fuel mileage then the 2011+ Duramaxs. The SCR helps increase fuel mileage vs the prior generation LMM engines.....Scooter can vouch for this. I have a few friends with 2011 Duramaxs and when they try to get fuel mileage ie. driving 65 on the highway they can get 19-20.
