3.6, auto, 5.13s. 37x12.50, 3.50" lift = 13.5mpg
I was 17mpg average during the summer.
I'm sure the drop is due to the combo of winter blend fuel & remote start idling to warm up on frigid mornings

Believe I read somewhere that the bigger killer during the winter is increased air density really ramping up drag vs winter fuel blend costing more MPG (at least for moving MPG, the idling is a killer too)
