Something is very very wrong with your vehicle and it needs to be taken into your dealer ASAP. There is severe friction occuring somewhere in your driveline (anything wrong with the engine would be throwing codes left and right), you are severely out of alignment, or a brake is dragging and continuing to drive this vehicle is only going to make those things worse. Even when mine was BRAND new (< 20 miles on the odometer), I still got 16+mpg. 8 is beyond belief. Don't leave the dealership until they either find the issue and correct it, or they give you a new Explorer.[/QUOTE
I HAVE APT NEXT WEEK. I will stand my ground. I just thought it may of been common. I heard some crazy numbers for the hellcat so I was in awe.
