So I'm on my way home from summer vacation and it's a 10-11 hour drive over two days. I decide to find out for absolute sure WHAT mpg this car can get. So after a few hours on the road I pull into a truck stop (I realize now that this time spent on the road in the beginning reduced the displayed avg. mpg for the trip), found a small nozzle pump and start to fill up with b5 diesel. The pump kicks off after a few gallons so, just to make sure, I top it off just once. I pull back on the interstate, hit zero congestion, and drive 116 miles at 60 - 65 mph. I then pull into the rest stop. I hit the men's room (priority 1!) then went for gas. At the pump I take it slow to try and minimize backwash. I do not try to top it off this time. What you see here are the results.
