It didn't do anything for me. I usually wish my hair about every 5 days. I didn't notice a difference. Plus, this product had leaked during shipping.

Great Story. I have a 2003 Toyota 4Runner with 217K miles on it. I am trying to sell it and the one thing holding it back is the check engine light (CEL) with the code P0430 (Catalyst System Efficiency below threshold Bank 2). I have had it checked out and of course the repair shop "oh you need a new catalytic converter on the passenger side...there is some nasty stuff coming from the exhaust." blah blah blah. I even told the guy to check the 02 sensors if at all possible and that I was selling the car and I wanted to avoid spending a ton of money. They never did check the sensor, but they were more than happy to charge me a cool $115 to tell me what I already knew. Long story short, I put 2 cycles of Cataclean in and I passed the emissions inspection yesterday (never thought it was possible!!). Now, I can tell you that the CEL will stay off for about 60 miles or so then it comes back on. So it did not fix that issue like some of the other reviews (I just unhook the negative terminal for about 10 minutes or so and get it to reset). However, I firmly believe that this stuff did do something to clean out the fuel and exhaust system enough to get it to pass which is the ultimate goal. I think it is safe to say that there is absolutely nothing wrong with the Cat and I can attribute the CEL to a bad sensor. I would think the emissions testing facility would have caught the cat whether the CEL was on or not. Words cannot express my disappointment in the repair shop that gave me the diagnosis of a bad cat. Bottom-line, give this stuff a try. It may not turn your Check Engine Light (CEL) off but it will do a good job of cleaning out the system (as advertised) and possibly help you to pass the emissions test. I did follow the instructions and ran it all the way down to below a 1/4 of a tank, put the Cataclean in, drove it for another 20 miles and then put in premium fuel. I did 2 cycles of that back to back. I could even tell the MPG improved. I am getting 19.5 on a V8 4Runner with 217k miles on it. Hope this story helps!

I've been using this for nearly two months on the area where I used to have eye brows, so far I've seen no improvement.

Leaked worse after using it and no resivoir wasn't overflowing went from a quarter size to 8 ozs. leak after 3 days
