   This absolutely works! I had to smog my car this year and it failed due to two errors. The O2 sensor and Catalytic converter were showing errors. The Smog guy said the get some Catalytic cleaner and drive it for 15-20 minutes and get Chevron 93 octane. I bought a different brand of cleaner which Guaranteed to pass smog or double your money back. I did as instructed and went to get it smoked again. FAIL!!! The smog guys said to buy Cataclean and come back. I filled the tank to 1/4 and added the Cataclean. Drive around for 25 miles at 55 miles per hour as suggested and went back. PASSED!!!! I was so happy I didn’t have to spend a thousand on a new Catalytic converter. This stuff 100% works and I would recommend it to everybody.

   Got rid of my P0420 catalytic converter engine warning light. I followed the instructions. When the tank was 1/4 full I poured 1 bottle and drove around. When empty, filled 1/4 tank (this time i put the more expensive gas as i had heard that also helps to clean out the catalytic converter) and poured a second bottle and drove around more. Before the tank was empty again the check engine light magically turned off by itself!!!

   Did as directions said. Then filled tank up, drove around 200 miles light finally went out. I'm still changing O2 sensor bank 1 for code 420. Will see if light stays out permanently.

   Used it in a 2007 Chrysler Pacifica with more than 100K miles. It was throwing a code indicating the cat converter needed to be replaced. When we were down to half-tank of fuel, I added this bottle to the tank. No special driving but I focused on longer drives to get the car warmed up and the cat converter hot. The light went off quickly and has stayed off for weeks. I'm very pleased.

   Long story short - I had a random misfire problem with my 2002 Mazda MX5. It took over three weeks of random misfiring for us to finally resolve the problem. Major tune-up wires plugs coils. After the check engine came on with a P0420. Used Cataclean according to directions. Check engine goes out, but returns. after filling up again and driving about twenty miles check engine goes away for good. Get successful emissions test three weeks later. Damn good fuel system cleaner for deposits on O2 sensors, Cat and fuel injectors. Somewhat better gas mileage and performance

   Cleared check engine light on my 2013 Ford Taurus, 108k miles. Nice/ok condition, always premium oil changes on time, new breaks, tires, my “keep until it’s dead“ car. My light popped up, code was for OX sensors, brought it in and spent $800+ replacing all 3 oxygen sensors. Light came on next day -replace Cat Conv code this time. Came across this stuff-put it in with 1/4 of 91. Drove till empty, filled up with 91 again-light came off! Went on 4hr road trip, 8hrs there and back on highway total, went to work-light still off. Car drives like BUTTER too, I can tell big difference in “power boost”! I think in my case my oxygen sensor did break then new sensor was touchy picking up old “dirt” from my catalytic converter? Light only been off for a week but so far this stuff works. But my car was overall in pretty good shape before this check engine problem.
