How to get better gas mileage? So last november I bought a 2010 prius 2 with 70k miles on it. I never got it checked out by a mechanic before I bought it (and still haven't) and only skimmed the carfax briefly. 

Anyway, I checked, and I'm only getting about 41 mpg. Is that normal? I feel like I should be getting closer to 50. So I wanted to know: is there any maintenance I can do myself or anything I need to have checked out to increase my average mpg?
