2X Cans Catalytic Converter Cleaner, Oxygen sensor cleaner, pass emissions, SMOG, fuel additive, combustion chamber cleaner

Amazing, My truck check engine light had been on for 6 months . Ford 2013 with 240,000 miles. Codes read that catalytic converter was bad and code also showed a fuel issue. My inspection was due , so I went ahead and gave it a try. Added 1st bottle with maybe 6 gallons of gas in tank and fueled up about 7 more gallons of premium. Ran a few days back and forth to work (about 70 miles ) but light was still on. On 4th day added the other bottle and ran truck 2 more days (about 30 miles ) . To my surprise driving home after 2nd bottle added the light was off . Immediately drove to inspection station and passed emissions test. Would highly recommend this product , and I will buy again.

Did a great job of cleaning my engine. Have told all my friends to buy this it will make your car run better

Did not do what it was suppose May cleaned it light was still on

I bought these due to. I had a PO 420 stored on my OBD two scanner also pulled out the O2 sensor and cleaned the inside of the cat out running this now for a few hundred miles I’ve not noticed any difference at all a little smoother acceleration is all I’ve noticed.

Excellent product. I used it on my 1997 toyota Tercel and boy it completely changed the idle on the car. It really cleaned out the exhaust since now I feel a constant pressure when Input my hand on the end tip of the muffler. The car runs great now. I did have to use both bottles 2 months apart from each full tank. The 2nd time I used it it just finished open it up and it really made a difference.

This did NOT work at all. They shouldn't advertise that it is to help emissions. It's FALSE advertising. They are LYING.I contacted them and let them know that it didn't work. Do you know what they said? "Your catalytic converter is crack, melted, or damaged." My catalytic converter is NOT damaged at all what so ever. That's just their cop-out for everyone whose P0420 code did not get fixed after using this. Bull ROAR. Absolutely disgusted and disappointed with the company. Don't even waste your money on this. Do not even, it's a scam and a grift. Brilliant snake soil salesmen this company is.You have been warned.

was apprehensive with this product but gave it thumbs up because my Mercedes passed my smog test

After 2 rounds of this the engine codes for my 02 and cat sensors went away.
