MCS
Commute mileage, daily grind: 29-30 mpg normally. 27 if I'm late....
Highway cruise, 65 mph: 33-34 mpg.
Highway cruise, moving with traffic 75+ mph: 30-31 mpg.
Day at the race track, all out go, kamikaze style: probably about 12 mpg? But I didn't bother to measure--who cares?! (okay sloppy thinking, I'll keep track next time).
