Hello guys..
I am new to this site and really like what I have seen so far. Well, I recently picked up a 2006 Jeep Commander 4.7L V8 from a garage. I really like the way it handles/rides, but not pleased with the fuel mileage. I am getting about 14-15 mpg. Is this normal or is there something wrong with my Commander? This is my first jeep, so I don't know much about it. Can anyone suggest me some good tips to get the best fuel mileage?

Thanks.
