I have had my new explorer for about 4 months and love the vehicle except for the gas mileage performance. The actual mpg is not even close to the 28/20 advertised by ford. I get more like 23/19 on average. I have tested it on several different trips, resetting to get highway mileage only, using different speeds, cruise control etc. Not even close to the 28 mph highway advertised! In fact I checked the gallons pumped for 6 fill ups, and in every case, the amount of fuel pumped (purchased) at each fill up was more than the car's trip computer calculated in every case. So, the calculated mpg is even less than what the car's trip computer is reporting! I guess I didn't really expect 28/20, but I didn't think I would miss by 5 (or more) mpg! This is a big difference, and I am disappointed with the results. Maybe a case of false advertising???
