my truck got 22 mpg on the way home from the dealership(trip 150 miles) gone down eversince. I was told that same crap, it will get even better once it breaks in. The over head now stays around 13 in city and up to 17 hwy. Mine is also a straight drive which is suppose to be better. I wouln't look forward to any better milage. 6.7 nice power but milage SUCKS and fuel here $4.19 a gallon.
