I hope it gets better when it breaks in. I have 1450 miles now on my SEL V6, using tank to tank calculation yesterday (22.4 average mpg),
that's 90% E'way driving. If I reset the dash readout when I get on the E'way & check mpg's when I get off E'way(for 20 miles, 30degee air temp), the car will get 27.8 to 28.4mpg, although I did get a reading of 31.3mpg when weather was better. All city driving would SUCK (gas). 8) p.s. love the car, but can't keep black clean in MI.
