It really, really depends on how you drive with the 2.7. It is a small engine in a heavy car. When I drive the trep, I can get close to 400 miles pure highway, or about 350 mixed on a tank. I can get roughly 30-ish mpg mixed. When my leadfoot wife drives, it will get about 280-300 mixed on a tank, she will average about 25-ish mpgs. I get better mileage because I also drive a 95 Ford F150 and I have conditioned myself to drive efficiently, because that thing gets around 12 mpg mixed with good driving. If I drive like an ass, I get 9 mpgs. Never good. Also, winter blend gas sucks anyway, you always lose a few mpgs on winter blend.
