the question is i used to put that in my rallairt once every 5 ish gas tanks,
would it be good or a waste of money or is it just going to damage something ?

 

With having a turbo car, you can use it, but you have to be more careful I would think because it basically just burns hotter than gasoline and burns off the carbon. So it may raise the temps in the exhaust system. If your going to use it, I probably would run through an entire tank of fuel before getting on the car hard again. This is just my opinion, I'm sure others have things to add. I used to use redline's fuel cleaner
