OXICAT - Oxygen Sensor, Catalytic Converter and Turbocharger Cleaner - 2-Pack for Preventive Maintenance (500 ml)

Bought this as a last ditch effort to clear some CAT codes off my 2013 Ford Flex and didnt change a thing, so not useful for me at all, but maybe as a preventive on older cars it might be wise, just dont think this will clear any codes and solve any cat faults (clogs, etc.) like I wished it would.

I had a p411 and a p420 code I bought oxicat put it in my fuel tank. But I also changed the spark plugs and changed the oil. I cleared the codes and they never came back. I'd like to think that it works. I've bought 4 cans and used 3 over a few months no more check engine lights so far.

Oxicat works well. Catalytic converter system was very dirty. Replaced one of two converters, and both O2 sensors. The dreaded check-engine light kept coming on and off. Used several Oxicat applications over the coarse of about six months, did the trick, light off now for several weeks. Last purchase for annual maintenance.

Put in second can today hope it help clean out converter they are 3000$

It really hasn’t did anything to help my o2 sensor
