i commute 86 miles per day round trip and typically will get between 29 to 31 mpg depending on whether or not i'm doing 65 or 80 which is typical on i-684 which is our main artery between putnam county where i live, and westchester county where i work. i'm pretty bad though. i'll squeeze out 325 to 340 miles out of a tank, and when i go to fill up i've got anywhere from .8 of a gallon to a whole gallon left. my fuel pump must hate me!!
