We are the original owners of a 1999 Ford Explorer Limited that we drove off of the show room floor about 12 years ago. We now have 250,000 miles on the original engine and transmission. We drive it everyday and we still get over 20 miles per gallon…more on the highway. It is amazing what you can get with regular oil changes and the preventative maintenence that your mechanic recommends. John and Karla Scott, St. Louis, MO
