Review: Excellent Product - It works really well. I used it on quarter tank and drove about 6 miles then filled up with top tier gas and my MPG went up by 3 miles on Highway and about 2 MPG city driving. At first there may be slight hesitation as it clears carbon. Then runs smooth as silk.
Review: So far so good - It seems to be working well, so far. The check engine light turned off and the my vehicle seems to be running well. Be sure to follow the instructions. A while back, I wasted some money on a different catalytic converter cleaner because I put the cleaner in on a full tank of gas. It's best to wait until you're at a half tank or less of gasoline before you put in your catalytic converter cleaner. Also, I drove around right after I put in the catalytic converter cleaner and before I filled up my tank again. A couple of days later, I went to the gas station and topped off my tank. Again, it seems to be running well for now.

### ⭐⭐⭐⭐⭐ PASSED MY INSPECTION! THIS PRODUCT WORKS LIKE A MIRACLE DONT HESITATE TO BUY IT!
*by M***G on January 13, 2026*

Inspection on my car due the end of January! My check engine light was coming on so I checked with a code reader & found it was a P0420. Read about the Catalytic Converter System possibly being in need of replacement or perhaps clogged. I am a woman, and know next to ZERO about cars, but I can read. Did investigate and found that the replacement of a Catalytic Converter system is mad expensive- also found this Moly Cleaner to add to gas tank. I'm not going to lie; I was nervous as I have a Kia Rio 2014 that has a very small gas tank and gets great gas mileage. In reading the consensus seemed to be to add to 1/4 tank of gas and drive fast for good periods of time to blow out the clog (if it was a clog). Did I mention I live in NYC and driving for long periods of time at high speeds can be a problem because of terrible traffic. Anyhow, this Saturday I poured the can into my 1/2 filled tank and hit a parkway near my home early morning. I did drive for 45 miles sometimes at 80mph then 60mph but tried to do it for a good few minutes at a time without getting pulled over. Checked my reader again, and it was not quite ready but the engine light did stay off. Next day, drove to work, stuck in traffic somewhat & never made it over 20mph & checked my reader again- all good to go for inspection. Went last night- my car PASSED and got that sticker in my window- so I am good for another year. The BEST money I have spent all year. Thank you for carrying this product! Saved me thousands! DONT HESITATE TO USE THIS. The hardest part for me was removing the cap on the can!
