Finally had a chance for nearly pure highway miles. From Columbus Ohio to near Philadelphia Pa. Very mountainous/hilly area. 427.9 miles on 7.912 gallons. My commute average is around 41mpg right now, so I had no idea how much this car was capable of on the highway, maybe it's time to invest in a scangauge??? I also got a 47mpg tank with my first 500 and 600 mile tanks on this trip.
It was quite exciting
