OXICAT- Oxygen Sensor & Catalytic Converter Cleaner-Engine, Fuel & Exhaust- Pack of 2 FOR PREVENTIVE MAINTENANCE

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

Very disappointing. We’ve used two cans; each time, our check engine light turned off after three days of adding it to a fresh tank of gas, but, both times, the light turned back on after only three or four days. The German manufacturer isolates itself from its customers by directing all attempts to contact them back to Amazon, and Amazon, of course, is notoriously opaque and inaccessible to its customers. I want somebody to explain to me why this product only appears to work for four days and whether or not additional treatments will be of any use, but there is literally nobody to ask. Is the only point of this product to turn off your check engine light long enough to get your car inspected? Really? That is not acceptable.

I use to sell this at the shop that I worked at and it works Great. With that being said if you are buying this to clear a code for a bad converter and not for preventative maintenence you have to do it shortly after the check engine light has come on. This will not work if the light has been on for months. I had very successful results by adding a can, filling with high test gas then using the second can with another tank of high test, then using your standard octane after. Highly recommend giving this a try. I saved my customers tons of $$ using this product

Working so far value for the money
