Does the job to clean your auto's fuel system; that helps increase the life of your engine.It is one of tne better fuel cleaners on the market.I use it in all my auto's,for some twenty years now.
I followed directions, emptied contents before filling gas tank. Kept records on my mileage and MPG and after two sessions of using Rislone increased my MPG from 21 to 25 MPG. Vehicle ran better too.
