Beating MPG Estimates
 I'm averaging 51-52mpg on every tank, and this is on a relatively new Prius. I've heard that it increases after the hybrid system has several thousand miles to break in.I'd highly recommend a 10 minute YouTube video on how to maximize Prius mileage, instead of reading hours worth of blogs.It's called Prius 2010 MAX MPG Secrets by Yavor54.For highway drivers, there is a huge drop in MPG as your average speed goes from 55mpg to 70mph. If not in a huge rush, you'll get much better MPG slowing down a bit. Check EZ-Pass regulations, or state benefits of having a "Green" car. You may get access to HOV lanes even when driving alone, or get discounted bridge tolls during off-peak times.
