Location: Lucas, TX | I have a 2012 2500 Duramax longbed that now has 9,000 miles on it. I am only getting between 14.5 and 16 mpg around town. Mixed FM roads and some in town stop and go. My 2004 Chevy Duramax 1 ton dually would get 17 - 19 mpg under the same conditions, same roads, same trips. Towing a 2 H GN I am getting about 12 - 13 mpg. Is there a trick to getting better milage out of the 2012? I was getting 13mpg towing the same trailer with the 2004 chevy. | |

Your 2012 Duramax has stricter emissions systems (DPF, DEF, EGR) that reduce fuel efficiency compared to your 2004 model. To improve mileage, try a high-flow air filter, keep tires properly inflated, use quality diesel, drive conservatively, and avoid excessive idling. A mild economy tune or DPF delete (where legal) can also help. | |
