I have the problem of Prius 2010, you walk with me a gallon of 15 miles. What is the reason? I am ti

welcome!
trade in for a gen 4. gen 3 (2010 being the oldest) has a massive egr clogging problem which will kill your mpg's, then blow your head gasket.

how far did you have to walk for that gas, were you a long way from a station when you broke down?

 

taxi, public transit, carpool, uber, lyft, bicycle.

 

Where are you located? How many miles on your 2010? Do you dive in very hot or cold weather? Short trips? High speeds? Any other problems with your Prius?
