We finally got some snow so I drove my 2012 JK Sport in 4x4 high for the first time. About two hours driving on the highway getting 21-22 mpg. I usually average about 18-19.
Even with 31 inch Hankook M/Ts I average 22mpg if I keep it locked in at 60mph. But the second I hit even a 1% incline in the road my mpg's drop drastically.
