Trip from Atlanta to Wilmington, Nc w/ my son. Filled up 2 miles off the expressway and ran interstate the whole way. Cruise set on 72 and did not have to use the a/c as temps were cool that day. Car made 377 miles on the tank and got 27.14 mpg, by far the best I've ever gotten. Previous was 358 miles on a tank. I ran 93 octane the whole trip. The low fuel light came on and i went another 10 miles till I found a station. The last 75 miles i slowed down to about 65mph. Very pleased w/ this, car is mostly stock and has stock 3.27 gears.
