I just got 460 miles on one tank on my trip to Atlanta for NOPI in my 05 6mt sedan, traveling on cruise set to 80 mph. When I filled up, I only put in 18 gallons, so I could have gotten over 500 miles, if I ran it till dry. That works out about 25.5 mpg. Around town, I get 17-19, depending on how much fun I am having.
