I get about 21-22 with mine and it's mostly commuting. I don't baby the car, but I don't do burnouts either. Average speed is something like 33 mph. On the freeway I usually run between 70 and 80, and I accelerate with about 75% throttle but short shift unless I'm really in "fun mode". Most days the car never gets over 3,000 RPM. On fun days it hits 6,800.
