Welcome to GS.
By the looks of it, the ZX2 has quite the potential for some good fuel economy numbers. Feel free to browse around and especially take a look at the
Busted and Confirmed Mods area if you like to tinker.
Also, driving style can really affect your bottom line. If you have a chance, a feedback device like a ScanGauge can show you instantly what MPG your getting under a variety of conditions.
Let us know if you have any questions -- good luck on your journey!
