I advise you to read this if you are considering the diesel. Love the feel, the drive, the interior and and comfort. Please Ford, take this lemon back! I am getting 8mpg highway - no load! Less than 6MPG with a load. Ford are aware and will do nothing about it. As far as they say, they never claimed better mileage, just better emissions.
