   Cleaned my cats out after two bottles. My cats were not that plugged but did have over 100k miles on them so it only made sense.

   I liked the product but, it didn't last 5000 miles for me. More like a tank full.. I felt the difference after putting it in the tank( drove the next day ) I had full new power of my vechile but it was was only short lived... maybe because my cat was bad for over a year or more when I brought it

   I have a 2016 Toyota Camry with almost 230,000 miles and just this winter it began to show its age and mileage in the engine performance. I used this thinking it can’t hurt but to my surprise it worked awesome. My engine is back to running smoothly and even got the boost back in my engine. Looking forward to continued use helping to keep me going.

   This product is great. I was having problems with my catalytic converter. My check engine light was on and my mechanic told me my catalic converter had failed and needed to be replaced. I have a 2013 Nissan Frontier SV. There are 2 converters on this truck. I went ahead and tried the product. I filled up the tank and added the whole bottle as instructed. I drove the car for a few days and nothing happened. When the gas tank got to about half a tank, the check engine light turned off. This stuff works.

   I used this on my 98 Toyota Tacoma and the Catalytic Cinverter was giving me heck. I already bought the part, but this worked so well will just hang on to the part till this does not work. Truck is running great. Gonna buy one more bottle since the converter has never been cleaned in 23 years.

   I'll give it 5 stars because I was able to pass inspection and now can wait to spend $1000 on a new cat when the timing is better for me budget wise. Put entire bottle in full tank after filling up and after about a quarter tank the check engine light went off after about a third of a tank. I had code P0430.

   This works wonders! I have an older SUV and A few months ago my check engine light came on, took it to the mechanic and said it was the catalytic converter. He put some cleaner in the tank and sent me on my way but said the light may come on if that’s the case we may need to change the part.

   This product works great the only thing is if your catalytic converter is broken or moving around or rattling it won't fix that if it's totally clogged it won't fix that if it's your oxygen sensors all it does is clean them off make your light go off and then later on down the road if you're not still using it it'll make the light come back on because it's your oxygen sensors that are bad not your catalytic converter otherwise this stuff works great blessings to you

   I used as directed. I emptied the bottle into my 20 gallon gas tank then filled my gas tank with gas. The second day I get into my fancy schmancy hyundai veracruz and the check engine light went off and it has stayed off. I am thrilled and happy with this product. I am a female, I did my research, I read all of the customer reviews and I bought with confidence and it did everything the product says it will do for the performance of your vehicle. I am so happy, I highly recommend it, to turn off the check engine light on your dashboard.
