Calculated 17 mpg going over the pass last week.everyone that says that a wj doesn't get 20mpg needs to just shut up and find out what's wrong with thier rig. I was talking with another tech the other day and he suggested if you have worn o2s the comp will turn on the o2 sensors heater for longer and longer intervols. He said that needs to be reset because when you install new o2s then the computer is still sending out such a long o2 heater signal it will either 1. Burn out the new 02s or 2. Make the new o2 act just like the old one because its heater is on for to long. I hooked uo the motis to the jeep last week and could not find this option. Maybe someone with an drb3 or veris can chime in.
Hell, I've never seen 17 mpg's since I bought the jeep in 07 with 40, 000 miles. And there hasn't been anything wrong with it, and I always keep up on regular maintenance. Must just be the way some people drive. I don't drive like a grandpa
