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.

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.

Worked quite well. I was pleased with the results.

It helped with gas mileage but not the check engine light. I replaced the purge valve on 2008 Pontiac Vibe about 2 weeks before I used this product and there was no change in mpg so I would say this works if you're looking for better mileage. The next thing I'll replace will be the O2 sensors and last (if needed) will be the catalytic converter to clear the check engine light.

It did the job more than expected within few miles of driving.

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.

Worked to get my Catalytic Converter engine warning light off for annual inspection. Works with less than 1/4 tank of gas after driven 15 to 20 highway speed miles using both cans. Note: your engine light will probably reappear once you fill up the tank with gas and drive for a while. This doesn't fix the converter problem, it just masks it for a while. None of these liquids can fix a converter that is really bad. They do clean the intake filter for a while.

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