Admittedly, it was under ideal highway conditions after filling up in Cheyenne yesterday, heading south on I-25 and setting the cruise at 85mph. I snapped this pic about an hour later on the other side of Ft. Collins. Interestingly enough, the real hand calculated figure is always around 3mpg higher than the car’s computer thinks it is. Not too shabby for a 3-liter twin-turbo diesel making 500 ft-lbs. of torque.
