How? I have the same year, trans and gears and I've been tracking my mpg's for over the past 11,000 miles (~year) with road trips and city driving only averaging: 11,315.1mi/912.00gal=12.41mpg; ~11-11.5city & ~13hwy. The highest I ever saw was only 14.92mpg on a road trip but only over a stretch...
