We just bought an '08 explorer for 19000. It was an executive model with 6500 miles on it. Its just a plain jane 4x4 with a v6. according to the computer it is getting an avreage of 18 mpg. When we pulled of the dealer lot with it it said 17 mpg. I suppose it will continue to get better as the engine gets broken in. If it gets 20 I will be very happy. We out in the country so 90% of our driving is all hiway miles.
