I have made several long distance trips (Indy, Atlanta) and averaged about 19 mpg. I did push it to 300 miles on a tank ONCE. The gauge is really hard to determine what is real. Always in Normal mode. Average 85 mph. Rush hour traffic drops the mpg to like 11. I think SpecRacer told me that Wet mode is better in rush hour traffic.
Hah, hah. Track (s)miles.Must be nice. Last 3 tanks I filled averaged 5MPG
