Increase fuel efficiency

[Guardian]

I am looking for semi-cheap, easy modifications to help increase fuel efficiency in my Patriot. It is 2011.

Does anyone know of anything?

Unichip is the only way to gain performance and increase fuel efficiency.

I am not sure if any other way you can incerase it. BTW is it really that bad, that you are looking for such alternate. Or is it just you who bought 8 cylinder right 4 cylinder corolla.

It's not terrible, I am just looking for ways to stretch a tank even further so I don't have to stop at the pump as much. I got a 4 cylinder too BTW.
