This stuff really works. I put in the right amount and added gas. I drove a few miles and it shut off the check engine light by itself.
1 of 1 found this helpful I didnt think it would work. But i watched some youtube videos saying it works. So i got almost a gallon of it. I put in the right amount and then put in a couple gallons of gas and drove a few miles. The check engine light was on for a P0420. The catalytic converter was below threshold. That light went out by itself. I didnt have to shut it off with my OBDII SCANNER. Pretty good stuff. I already gave some to friends and they had the same result.
