I've been renting a 2008 Prius for two weeks while my other car is being repaired after a collision. My car is supposed to be ready in two days and I don't drive that much, so this morning I pumped in $10 of gas (~ 2.6 gallons), but the fuel guage continues to blink like it's almost empty. I know I've got at least another 100 miles of driving before it runs out, but the blinking is worrisome.
