See GBMINIs MPG & mileage chart; the thin jagged line is miles between tanks (the few very low ones are "short fills" before a trip or similar); the MPG is on US gallons!
I got the JCW-200 in Jan'04 and upgraded to the -210 in Oct'04. So only two fills since the upgrade, but both over 300 miles.
The big driver of my mpg/miles-per-tank is if all my trips are just to and from work (only 11 miles each way) or if I do longer runs.
NOTE: I don't drive *hard* ... but I do have fun
