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.

Rated 1 out of 5 by Verified Reviewer 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

Rated 2 out of 5 by SGNJ 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.

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.

Rated 4 out of 5 by Bbailey 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.
