Awesome Product!!!!
I been using Gumout for about 12 years now on and off when needed. today the wife's car was struggling to get pass 40mph and when you did get passed it it would make the car start shaking as if it had a bad cough. Long story short I knew it needed Gumout so I went to the Advance Auto store bought some good ol' Gumout. I went to the gas station and put the Gumout in the tank and a half a tank of gas in. As soon as I left the the gas station I put some pedal to the medal and no more coughing/fuel injectors struggling. Use it every so often and your will stay running smoother.
