LIQUI MOLY 8931 Catalytic-System Cleaner, uncoloured

Working as should, recommend

Great value for money 😀 transformed performance on a 2003 petrol and brought emissions to pass level. Spray as a mist into air body whilst engine is set to 3000 revs the revs will purge and judder after take for a spirited run 😉

Use it as instructed on the Company official website. Works perfect, you will need to erase computer errors, eventually. Engine work smooth.

Good product, a solution to save money rather than replacing the part ! Have done this about a week ago let’s see how long it lasts !

Would've been great if this stuff worked for me but my Catalytic convertor must be shot. They may have been a slight improvement but the engine & stability control lights are back on and it runs rough at times and struggles up hills, poor performance when pulling away. I suspect this would be a good idea to use every 3-6 Months as a preventative in keeping the CAT in good health as long as the CAT is in good health to start with.

Arrived as described - works well.

Used two of these, spraying it into the throttle body as my X5 failed its MOT on emissions. I did as directed on the can, then took it down to the garage and they checked the emissions quickly only this time, it sailed though the test. This really works !! Excellent value for money

Can’t read directions due to there being a sticker in foreign language stuck right over English information

Lo compré porque se prendió el código 0420 lo apliqué en el cuerpo de aceleración borré el código ye tiene 3 semanas y no ha vuelto a parecer el código si vuelve a marcar el código modifico mi reseña

Marque connu, et produit efficace pour un prix raisonnable.

Good and working

Producto preventivo, usar con pulverizador directo al ducto de admisión! No se usa vertiendo en el tanque de combustible.

I used this on our L650S Mira Gino because the fuel mileage was bad. I bought a cheap sprayer to spray the liquid into the throttle body while the car ran. It created a lot of smoke. Following the treatment, I replaced the oxygen sensor after the catalytic converter. The car seems to have more power and is getting better fuel mileage!
