I did a 4hr round trip to visit family a few weeks back, mostly highway but a little city driving while I was there too. When I got back I checked the trip calculator and I averaged 25mpg. And I didn't drive like a grandma. Lol didn't race it either but on the 2 lane highway that we took I set the cruise to 70. I was hearing about poor mpg in here too but I was very impressed to find that.
