Just an idea for a topic as I sit here and think about my nicely cooled car... surely I can't be the only Prius II owner who gets a bit irritated at the gas gauge. I just filled up again (ha) using only 6.34 gallons. This is with the gauge showing two bars left. Anyone else have this annoying glitch? I wouldn't mind, if it weren't for the tank holding 12 gallons, supposedly.
