Fuel economy for GMC 2500 6.0 gas 4:10 gears

Asked by Sep 03, 2016 at 06:44 AM about the 2016 GMC Sierra 2500HD SLE Crew Cab SB

Question type: General

I'm looking at a 2016 GMC 2WD truck
2500HD with 4:10 gears and a 6.0 liter gas
engine.  Does anyone own one set up this
way in either a new or close year model
that can give me a realistic expectation of
fuel economy unloaded and towing an
8000lb trailer?  Any help is appreciated.

As you found out, the MPG isn't listed due to it being a truck for hauling, and probably low numbers. But here is a link to a GMC forum with real numbers...http://www.gm- trucks.com/forums/topic/190497-fuel-mileage/?hl=mpg
