Do I go to the interview or not?

I urgently need to get away from my actual job, and today I got an offer so I have an interview...but now I don't know if I should go or not, because the pay is almost the same as I'm earning right now, but the location is far away from where I live, so it doesn't cover the extra gas ... and I have going to an interview if at the end I won't be able to accept it. but at the same time it could be a good opportunity for me to start in a new company...ughhhh what do i do???
