OXICAT Oxygen Sensor, Catalytic Converter, & Turbocharger Cleaner for Preventive Maintenance

It worked like a miracle. My engine light went off due to my catalytic converter problem and I passed inspection today thank you and God bless Eric.

This product is easy to use and saved me hundreds of dollars in repairs. Cleaned out the catalytic converter and the check engine light went off. I applied both cans as directed on my 2015 Honda CRV with 180+ miles and it worked!

You all should know that: 1) a properly running car (correct A/F ratio) will automatically unclog your cat via high temperatures and gasoline as a solvent 2) oxicat is just varying amounts of petroleum distillates and alcohol. Solvents other than gasoline 3) most of these solvents will burn up in combustion. I would say the majority of cars with P0420 or P0421 just have worn out cats. You can get a generic cat and have an exhaust shop weld it on for you, much cheaper than OEM.

I’ve tried them all, this is the real deal. Well worth the cost.

Used it per directions. Light went off for a tank or 2 and then came back on. Easier to pour in the tank than to try and replace cats. It may work in some situations but in mine it was short lived.

This product really works fast and effective.

I don't do reviews .but was very happy with this product . Follow the instructions and when that tank of gas is empty , and you fill it up again drive it , the engine light will eventually go off.

Check Engine light came on, I cleared it with the trick of removing the negative battery cable. Forty miles later the CEL came back on and OBD reader indicated that it was either the Catalytic Converter or an O2 sensor. Poured this in the tank, 120 miles so far and no CEL. I'm taking a short road trip next week, so that will be the test.
