Rated 3.6 out of 5 by 18 reviewers.
Rated 5 out of 5 by Does what it says! I followed the instructions and me 2000 expedition is running smooth! I had fouled spark plugs and replaced them so it started running rough. But cataclean helped breakdown the stuff in my catalytic converter. August 11, 2016
Rated 1 out of 5 by Didn't work I followed the instructions, as well as advice from others. Then I unplugged my battery to turn off the light. 2 weeks later it came back on. This was a big waste of money October 29, 2015
Rated 2 out of 5 by A good treatment option. I was not able to see if the product worked or not. I believe I've used it too late. The reviews caused me to purchase it with the hope and possibility of it working. October 12, 2015
Rated 5 out of 5 by Notice the dffernce I love this Mr Gasket CataClean Engine and Catalytic Converter Treatment. My goal is to use it quarterly. i'm debating replacing my cats, but this is way cheaper and I notice the difference overall. September 18, 2015
Rated 5 out of 5 by It Works! Followed the instructions on the container and my 2005 Nissan Altima picked up lost power and ran much smoother. August 27, 2015
Rated 1 out of 5 by Tryed it ! All I can say is I tried it and it did not work .... maybe it was in too bad of condition. Now I am out $ 15.00 ( it was on sale ) August 14, 2015
Rated 4 out of 5 by I heard this stuff is great! My mechanic recommended it. He put in a new engine in my car and my engine light was still on with a code indicating the catalytic converter. I had replaced that three months prior. He said you prob need to clean the fuel, engine and converter. I put this in. I believed it did what it intended, but my car had issues bigger than this Mr.Gasket could take care of. Eventually I replaced the fuel pump, which took care another problem. But my engine light is still on. May 25, 2015
Rated 3 out of 5 by Worked well for about two weeks, then back to the CEL I purchased this product because my CEL was on with the code P0420. I used this product and reset the CEL, and it remained off for about two weeks and then it returned. So it did not perform as advertised, although it did seem to clean out the combustion system and my vehicle peformed better after use. Just didn't fix the catalytic converter issue. October 20, 2014
