It’s been a goal of mine to drive over 500 miles on a single tank of gas ever since I got my new Prius.
This isn’t all that difficult for other Prius drivers, but for my daily drive where speeds rarely exceed 50MPH, distances range from 6 to 16 miles, and stop-and-go conditions abound, reaching that mythical 500 miles on a single tank has always been just out of reach.
On July 3rd 2008 at 18:35 I did it, hitting 504.9 miles on a single tank, averaging 45.8 Miles Per Gallon (MPG). The “Low Fuel” indicator had been flashing for about 12 miles, and I could have probably gone another 12, but rather than push my luck I just snapped these (crappy) pictures as proof.
