Looking at the achievement page of the mileage database, it seems that the "farthest on a tank" area is corrupted a little, no fault to the keepers of this wonderful site (who do a fabulous job, might I add). 1,800+ miles on a Prius II with 57.4 mpg? That's over 31 gallons...seems like 2 tanks to me. I know the one for the HCH is over 2 tanks...I've contacted him, and he asked me how to change it. I told him, but he didn't do it...oh, well.

Just seems that this part of it really makes me wonder how real those numbers are.
