ColoradoSkiCountry Posted October 22, 2009 Share Posted October 22, 2009 Thought I would bring back an old post to see how the numbers are looking this year for you Duramax owners. And to hell with the poll that's old information! Link to comment Share on other sites More sharing options...
08_Denali_22 Posted October 22, 2009 Share Posted October 22, 2009 I'm seeing roughly 16-18 mpg per tank on average with speeds of 70-80 mph and a 70 mile round trip daily. Thats with the mods in my sig and a real rough EFI Live tune. Plus I hammer on it quite a bit. Link to comment Share on other sites More sharing options...
