Important information

Legal Disclaimer

OXICAT requires the vehicle to reach and sustain the working temperature of the catalytic converter. If the catalytic converter is cracked, damaged or completely clogged, OXICAT will NOT function properly.

Product Description

With an innovative new decarbonizing technology, AUTOPROFI OXICAT cleans the entire exhaust system, dissolving soot and carbon deposits throughout. TO BE EFFECTIVE, OXICAT REQUIRES THE VEHICLE TO REACH AND SUSTAIN THE WORKING TEMPERATURE OF THE CATALYTIC CONVERTER. Used regularly, OXICAT is ideal to help prevent the buildup of noxious residue that can cause a vehicle to fail required emissions tests. It is specifically engineered to meet or exceed recent environmental standards, protecting both your vehicle and the environment. OXICAT is specifically engineered to be used as part of a proactive care plan to optimize vehicle performance and engine life. It is NOT a "mechanic-in-a-can" and is not engineered to repair vehicle exhaust systems.

Noticeable difference on older car
I have a 2006 Mazda 5, with 125K miles on it. Have ran the usual fuel system cleaners through it from time to time and never really saw much improvement. Ran Oxicat through a full tank of gas, and it seems to have cleaned out the exhaust system. Exhaust pipe was sooty black before, so I'm hopeful it also cleaned up the O2 sensor and catalytic converter as well. Afterwards, the pipe was so clean, you can see the weld line in the pipe! The instructions indicate it needs the cat to be at operating temperature. I used the product on an out of state trip, running at turnpike speeds, to give it the best chance at cleaning. Car seems to be reving easier and at higher RPMs, seems to be breathing better. My recommendation is to use it before a long highway trip for best results.

I drive short distances, less than 10 miles, twice a week. I put AUTOPROFI OXICAT in the gas tank and filled it up, then I drove 150 miles, made a u-turn and drove back home. Now my car is more responsive and runs smoother. This will be the second can of AUTOPROFI OXICAT in six months. If it works as good this second time as it did the first time, six months ago, AUTOPROFI OXICAT has won a lifetime customer.
We'll see.

Added OXYCAT to my half tank of premium fuel on my 5 speed manual Chevy S-10, 6 cyl Vortex .. the truck is mint with only 41,000 miles but I got a cat CEL and slightly rough idle, installed new battery, replaced the PCV valve and now addressing the potential exhaust issues, .. drove twenty miles today at about 2500 rpm, CEL has not yet cleared yet but the idle speed has dropped to about 700-800 rpm, feels very nice starting from a stop, the idle sound from pipe itself is about fifty percent smoother and absolutely no issues during the twenty mile drive. The slight sulphur dioxide odor seems to have gone. I can sense something good is occurring. Will update as I see more progress ... all from twenty miles at 2500 rpm, ... updates soon

My check engine light came on and the code number indicated a oxygen sensor issue. I added a can of OXICAT, and filled it up with a tank of premium gas and took it out for a good long highway drive and the code light went out, so the situation is resolved. So I'm not sure if this is due to the OXICAT, premium gas or a long highway drive (As most of my driving is short city drives) , but I'm willing to attribute the results to the aforementioned product

Bought this expensive O2 cleaner. The manufacture states that it should work fine. The mechanic said that the O2 sensor is clogging up a little. He knows this from when the time ( 3 weeks or so) that the check engine light comes on an it is cleared. This cleaner was supposed to clean the complete exhaust system and now the light comes on about 2 days between clearing the code. It made it worst. I would try something else before I change the O2 sensor.

The check engine light kept coming on in my 2010 Subaru Forester indicating a catalytic converter problem. My mechanic said the Forester has 3 converters; a main one in the exhaust pipe which costs about $2000 Canadian and 2 smaller ones in the manifold. With labour total replacement would cost 3 or 4 grand. He did say it could just be a dirty oxygen sensor.
One can of OXICAT added to a full tank of fuel and run until almost empty, and the problem seems to be entirely solved. No more check engine light and the car runs better than ever.

4.0 out of 5 stars Great Product to pass your emissions test
Reviewed in Canada on August 8, 2022

I have been having P0420 and P0430's. Mostly the P0420 ever since my fuel pump died and I coasted off the highway. I tried out a competitor product at a similar price, and the 420 came back. I suspect that my 2014 Dodge Charger with 300 000km may have catalytic converters that are past their prime. However, I thought maybe they are just contaminated. I cleared the codes and ran the off the shelf product. 420 came back. I ran the Oxicat on a fresh 3/4 tank until at at least 1/4 and I drove it like I stole it hoping it would blast out the cats. I will say that after clearing the codes, I has 5 days of trips and one scan said 0 codes, 0 permanent codes. So, this will for sure help you pass an emission test. Sadly for me, engine light has returned, so I fear it's definitely time to get it professionally assessed. A mechanic told me, 300K KM's, most likely the catalyst has passed its prime. And, given these codes trip at -5% below optimal, I guess I just have to black tape the engine light, or keep resetting the CEL. (and get it checked if it's a bad sensor but I fear not).
