I have an 06 Civic EX coupe with automatic. Very pleased with the mileage. Just got back from a trip to the mountains, round trip a little over 600 miles of driving. Car has about 1300 miles on it now - back roads, not over 65, kept tach under 3K most of the time. Round trip avg was 39.25. On the way home, 200 miles after leaving the stop and go of the mountains and small cities, averaged just below 43 mpg. Neat little car.
