Hi all. My name is Sara. I just bought a used 2003 Prius last week. So far, I LOVE it. (My last car was a 1995 Dodge caravan). My gas mileage is a little lower than I would like; I think because so much of my driving involves a lot of hills. The Prius really seems to struggle going up the steep ones (although I think it's mostly that I'm used to such a larger engine). Does anyone have any advice on how to improve gas mileage in hilly conditions? If anyone else is in Pittsburgh, I'd love to hear if you have trouble with hills too (I live in Beechview).
