My 2018 2dr Jeep JL got 20 mpg commuting in the Seattle area (40 to 80mph). It had the 4cyl turbo and was running on 33's on 2in of lift. I was very happy with that number. Bone stock, brand new, I bought it in Boise and the trip to Seattle netted 24mpg. Having had a couple Wranglers in the past I about crapped myself with that number. As the tires get bigger and the rig gets taller that mileage number goes down. I'll be pretty happy if the Badlands 2dr can hit 20.
