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

I own a 2013 Town & Country van (122k+ mileage) that had the check engine light on. When a diagnostic was run, the garage wanted to charge me for a new catalytic converter. I did not want to just hand over 3K+ without knowing if it was just dirty or had an actual mechanical issue, so I researched catalytic converters and this product, purchased one can of Oxicat, and used it as directed on my van. After driving it for a day and a half, the check engine light went off - it cleaned the entire catalytic converter & exhaust system. My van passed its state inspection next day, and I've noticed better gas mileage, and smoother pickup when accelerating. I can't say enough good things about this product - I'd give it 10 stars if I could.

Great Product!!!

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 solvent2) oxicat is just varying amounts of petroleum distillates and alcohol. Solvents other than gasoline3) 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.

After, the CEL came on and I attached the code reader. It said that the 420 or bank 2 catalytic converter was not up to standard. Checked O2 sensors and they were reading fine.I thought oh no guess I will have to get a new car since it was 19 years old and had over 209,000 miles on it. Read about this stuff and thought what the heck, cheaper than a new car! I placed the order and it came quicker than it was supposed to. When the tank was 7/8 empty, I put a can in the tank of my 2003 Toyota Corolla LE, (which was 1 week after it threw the CEL on) at the same time as I pulled in to fill up the car. Took it for a drive on the freeway, and after 129 miles parked it. My wife took the car that evening to the grocery store and said that the light had gone off!!This product is amazing. It worked for my old car!* *UPDATE* * NOV 28TH * *It has been over 3 months now and still running fine, with no new CEL lights coming on. I will post after my emissions appointment if it passed or not next week.** UPDATE ** Jan 23rd 2023 **Car still performing great. Emissions found NO issues. Passed all of them. This product worked a miracle for me in a time when cars...(replacements) are hard to find and super expensive.

It not a miracle cure that’s for sure, my check engine light still went on…

The burning fuel destroyed my car when I started it.

this does nothing

I purchased this product to avoid having to replace my oil contaminated catalytic converters. After 2 doses my CEL is still on but my cars driveability and performance has noticeably improved. I believe this product is superior to any fuel system cleaner I have ever tried and I plan to use this at least once every oil change. I will continue with 1 or 2 more doses an an attempt to save the catalytic converters. It is worth the investment and I'll update this review if it works to save the cats.Update: The original vehicle this was used on still has the cat low efficiency codes. However. I used one bottle of this on a 2008 Volvo XC90 with the 3.2L engine and 200k miles where the low cat efficiency code just came on. After filling up and adding the product to the tank I monitored the downstream O2 sensors live data while taking a 500 mile road trip. I could see the sensor voltages stabilize to normal levels during the trip and the CEL has not returned for 2 months.Conclusion: This product appears to capable of reviving cats that are not severely contaminated. I would also say that high mileage vehicles that burn oil may also benefit from using this product as a preventative measure.
