Wife has a the 12' SE v6 ... sticker states 23 city & 28 hiway. She was getting 24 city & 34 hiway. Now with little over 12,000 miles on it, she's getting 27 city & 39 hiway. Thiis last trip was 340 miles of going from 5,000 ft elevation to little over 10,500 ft and back down to 8,500 and back again reversing same route. It's just like a fime lady ...gets better with age.
