Catalytic System Clean 300 ml 7110. Cleans The Injection System and The Combustion Chamber.

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.

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.

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!

2004 Honda CRV failed the emissions test. It had a P0420 code which could be a faulty catalytic converter or failed oxygen sensor. We did not want to spend a lot of money on it because it is an older vehicle and might not be a long term vehicle for us at this point. I let the gas get down to about 1/4 tank. Poured this bottle of Liqui Moly magic potion elixir right here and filled up the tank with premium gas. Drove it around for a couple days. Took it back to the emissions test and BAM! Passed with flying colors. Just like that! A shop would've probably made us buy a whole new catalytic converter for $2.3 Million. No Sir, Not ME.

2019 Ford F150-I bought this product with a 1/2 tank of premium gas in my truck. I had an emissions light on that I was told by my mechanic was catalytic converter related. Shortly after I poured the product in my tank (maybe 40 miles),the trouble light went off. The trouble icon stayed off for the next 100 miles but then came on again. After another 200 miles the trouble icon went off again and has stayed off so far about 1,500 miles later using regular gas.

Follow instructions and it will work. Had a p420 code, caught it early used this. No more code and passed emissions

A very good product. It helped the car feel smoother to drive and was easy to use. I would buy it again.

Seemed to work as well as or better than some more expensive catalytic converter cleaners. I put it in while at 1/3 tank and my Check Engine light went out almost immediately once I started driving. My Tundra has almost 230,000 miles and still runs great but was getting a little harder to start after I switched from full synthetic oil to conventional. I’ll never do that again and immediately switched back but the damage was done. Check engine light came on and I had to crank longer to get it started. Adding this Liquid Moly fixed both issues temporarily. I have to wonder if this was used regularly, say every 3 months, if it would clean the catalytic converter more permanently?

Tengo un Ford Focus 1.0 ST Line y me apareció un fallo relacionado con gases de escape. Probé este Liqui Moly Catalytic-System Clean, lo añadí al depósito y llené el tanque. ✅ Antes de terminar ese depósito, desapareció el aviso. 🔍 Resultado El testigo/fallo se fue durante el uso del depósito. Pasé el OBD después y ya no aparecía el error de gases. 🧪 Lo que me gustó 🧼 Da la sensación de que ayuda a “limpiar” (inyección/combustión) cuando el problema viene por suciedad o acumulación. ⛽ Uso fácil: añadir y repostar, sin historias. ⚠️ Importante Esto no sustituye un diagnóstico si el fallo vuelve. Si el aviso reaparece o el coche va raro, mejor revisar (sonda, catalizador, fugas, etc.). En mi caso, cumplió y me ahorró un susto.

Does what it says on the tin, you can smell the difference after a few days

Put this in a friends Hyundai (1.6L) Veloster. This engine burns oil (as they ALL do) and this coats the catalytic converter causing codes. Replacing the convertor with a GOOD new one is expensive. So we rolled the dice. Installed with about 1/ 2 tank of fuel, cleared the code, and then told her to drive it until the tank was low before refilling. Also told her to take it on the freeway to get the engine good and hot and get the converter good and hot to aid in cleaning it. 3 months later, the code has not come back and prior to using the cleaner it would recur every week or so. A good converter for this car is roughly $900 and it's just going to get coated in oil again due to it being a Hyundai engine that burns oil. So, this can, with 1/2 tank of fuel, and some freeway (120 KPH) driving to get the converter hot appears to have worked.

Emisyon değerlerini kesinlikle iyileştiriyor, bunu yaparken ısıya ihtiyaç var, yaz aylarında uzun yol esnasında yapmakta fayda var. Bu sayede farklı devir aralıklarında daha etkili olacaktır. Ben 2 kutu kullandım önce 600 km lik yolun gidişinde, sonrasında tatil biterken dönüş yolunda. Senede 1 - 2 kez kullanmak etkili olabilir.
