Gas Mileage with lift kits (3.5"-6" lifts and 35" and 37" tires)

What kind of gas mileage are y'all getting with your different builds and setups. I want to put either a 3.5"-4" lift with 35's or 6" lift with 37's. I am currently getting 15 mpg in the city and 18mpg on the highway with a 2" leveling kit and 285/60/20's.
