2X Cans Catalytic Converter Cleaner, Oxygen sensor cleaner, pass emissions, SMOG, fuel additive, combustion chamber cleaner

Good to use every so often so your catalytic converter doesn't plug. So much cheaper than waiting for the catalytic converter to plug and then needing replacement.

“This catalytic converter and oxygen sensor cleaner works well. It helped improve my car’s emissions and fuel efficiency. Easy to use by just adding it to the fuel or combustion chamber as directed. I noticed smoother engine performance after a few uses. Good value for the price.”

If you use it and see a difference, you will blame it on this cleaner, if not, you will say the product does not work. Exactly like your weight loss supplements! Who knows what this stuff does, but it may do something. Or maybe it does not.

This actually worked. My check engine light went off after using this. I only used 1 for now. It probably would have worked faster but I don't drive alot. I will definitely purchase again soon to keep in stock.

Brought a 2-pack thinking it's going to work. But it did not clear the check engine light . I had a exhaust valve leak which caused more damage then I thought of. But I did notice more acceleration and slightly better gas mileage .

I was skeptical about this product but I was surprised that it worked. I added an entire can to my gas tank when it was half full and drove normally for 150 miles until the tank was almost empty. I fave since driven 100 miles and the check engine light has not come on. The catalytic converter and oxygen sensor code have not returned. My car was inspected and the emissions check was good. This stuff works.

I had a check engine light and OBD II sensor said it was the catalytic converter. This was my “least and easiest” attempt to solve the problem, and it WORKED.

I am revising my review. The product worked initially, then code came back, and now codes gone again after driving it a few days. So I guess it has worked better than I thought when codes came back. Not sure but I will monitor and revise again if needed.

Cambie el catalizador de mi auto por uno con media vida remanente, y despues del tratamiento se siente una diferencia positiva en la aceleracion (asumo por una mejor salida de gases)

Reasonable price for the quality, the content can be mixed with 1 fuel tank it is much easier to use compared than others that need to be mixed with quarter tank and driven to 50 miles.

VALUE FOR THE MONEY , The most easiest and SAFEST Way to CLEAN YOUR ENTITE Fuel System ONCE and DONE!

Easy to use. Need some indicator of success. Need more information to know if I should continue to use more than 1
