So far so good even though the engine light has come back twice. My guess is that it's a 7 yrs old cat and I think the fuel quality has something to do with the engine light coming on and off. I will re-order more for a deeper cleaning!

Hi, I'm giving 4 stars only because its hard to tell if it did anything to the catalytic converter/lambda sensors, but when I checked the spark plugs they were white as new which is also dificult to decide. Expect anomalyties with the ignition since the product changes the octane of the fuel.

This product is amazing. It worked. I used it with a little less than a half a tank of gas and ran it down to a little under a 1/4 tank and filled it up. My 420 code has not returned.

I received Oxicat in the mail and decided to do a before and after test. My car is a 1999 Honda Accord 2.3L . First I did a hand feel test of the exhaust flow out the pipe and I noticed that it did feel kind of weak. Second I used an Infrared thermometer and took a test of the temperature of the inlet pipe and outlet pipe of the Catalytic Converter. The pre-test showed a measurement of 343 Degrees on the inlet pipe and 400 Degrees on the outlet pipe. I started off with 1/3 tank of gas and poured in 1/2 the bottle of Oxicat and drove about 110 miles. I use my car at work as a Courior so this worked out great for me. The next day I filled to 1/2 of a tank and poured in the other half. At the end of my route or another 110 miles I ran another temperature check like before and I could not believe it. The inlet pipe measured roughly the same but the outlet pipe measured between 440-460 degrees. Also I should mention that before I ran my tests I was getting a check engine light code p0420. I also cleared the code prior to running my tests and ever since I did that the check engine light has never come back on. I did a hand flow test again and could tell that the exhaust was flowing a lot better. The fact that the outlet temps have increased along with better flow shows that this Oxicat made a big difference for me. : ) I Believe Oxicat has worked because my Cat was not 100 % blocked if yours is at that stage, then this might not work for you. If you get a p0420 code and yet can still feel some flow out the exhaust then by all means give Oxicat a chance. My advice would be to follow the same procedure I did by using 1/2 can per 1/3 tank and try not to dilute it so much. Another is you need to drive it a-lot like I did for this to work.
