A123 Prius Plugin

It got almost 6000mi - most of the time I leave it sitting in the garage and drive/ride something else. I learned early on the trip computer needs to be zero'ed whenever you want accurate data from it, but my gas mileage has always been mileage/gallons at the pump - what the deale calls tehold fashioned way. The number on the trip computer right now is 15.7mpg.

The trip computer is amazingly accurate, but only if you zero it and let it stabilize whenever you want a good number.

What caused you to sell yours?
