I bought a 2010 prius a few months ago ( warmer weather). I was getting @ 50 mpg. Yesterday, I filled up and I' m down to 33 mpg. Why?
I have 2 Prius, 2008 and 2013, you cannot go by just 1 tang of gas for your mpgs but the Prius does not do as good in cold weather and wet conditions. I mostly get 55+ on my 08 but I drive easy and I do not have to go on interstate hwys but a little. Keep up with it and it should stay close to the 50 mpgs unless you drive it hard and in a lot of bad weather. If it stays in the 35 mpg range on multiple tanks then you need to talk with a Toyota service center. Good luck!!!
