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

This product solved a long-running issue that even Ford couldn't fix. My engine warning indicator was constantly on, causing terrible pickup and low mileage. I wasted 16k + labor replacing the catalyst sensor, and it still didn't fix the problem. ​Bought this as a last resort, and it worked like magic. It’s been nearly 2k km now—zero warning lights and absolutely no performance issues. Highly recommend!

Works well for older high kilometres done cars. Adds a bit of peppiness to the engine as well. Seems to have worked in my case where it was able to contain a catalytic converter issue.

Works well, did help clean catalytic converter for my 13 year old petrol car.

Clears the system & some emission errors too.

Superb , it cleared the O2 sensors and catalytic sensors an mileage increased from 9 kmpl to 17 kmpl

I really did not find a difference in the mileage. I own a 2010 Honda CRV and really can't say if there is any change or difference in the car after usage of this product. The car seems to run much the same as it did earlier.

My car's average mileage is 8 km, but after this usage, it's 20 km.

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.

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.

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.
