  I put 6 bottles in the butterfly of an Opel Astra G CC from 2000 a day before the inspection, and the guy there told me what a clean catalyst it has for its year

  Used on Mondeo.mk4 2009. With error p0420 for the catalyst. It was giving me an error at 30 to 40 km. The first time, although it showed something, the error appeared again.

  In the 3rd bottle, I noticed a significant difference in acceleration and consumption. So far, it's at 100+ km and hasn't shown an error. I hope it continues!!!

  Hello..
  In a 2005 Lancia Musa with Lovato LPG and 333,000 km, I got a p0420 error. At first, I cleared the error from the diagnostic tool, but after a few kilometers, it reappeared. I bought this product, applied it, and I have driven about 800 km without the error showing up again. It probably did the job... I might buy it again as a preventive measure to keep the system clean when I have time.

  (For those who don't know how to use it. I took an old spray bottle, e.g., from Azax, emptied the liquid inside, and started spraying it directly into the engine's air intake. That is, at the throttle. First, I had started the car to warm it up, and at a steady RPM of about 3000, I began to spray it until it was finished.)

  I didn't see any difference in myself without meaning that it doesn't work of course it always depends on the problem

  I tried it with a pump on an Astra that was stalling and it didn't make any difference, nor did it emit anything from the exhaust. After a few days, I added the catalytic system clean to the fuel tank (even though it is considered a maintenance product) and now the car runs smoothly.

  I bought it for my own Ford Focus and a friend's Ford Fiesta as the check engine light was on with error P0420. If you follow the instructions correctly, watching the company's relevant video on YouTube, it does a good job. Of course, if you see what the catalyst emits in an open space, you will understand.

  You can't know what's going on inside, but you can notice a small difference in sound and how the engine works. Always use it with a sprayer! Read the instructions for use!

  I used 2 packages, the car immediately unclogged and the consumption also decreased. 4 days later, everything is fine. It really did the job! If anything changes, I will come back.

  It was used in a Toyota Yaris with 240,000 km, in combination with the "Liqui Moly Pro-line Carburetor & Throttle Valve Cleaner Spray" because it triggered a check P0420. Read how it is used (with a pressure sprayer), also watch the official company videos on YouTube. It did an excellent job (reducing hesitation and "breathing" the engine), but if the problems persist, visit a trusted mechanic. All these additives are good and useful, but not a cure-all for all car issues that arise.

  So regarding the product, I have a Ford Ka with 140,000 miles on it, the engine light came on, diagnosis showed a problem with the catalytic converter, I turned it off repeatedly but it kept coming back on. Therefore, the result was to change the catalytic converter. Due to the cost and after doing some research, I decided to try this specific product as a last resort. I bought it on 26/2 and I sprayed it through the intake using a sprayer at 2000-3000 RPM. The car emitted smoke from the exhaust in Arta and Ioannina (smoke). It made some rattling noises as I was applying it, but then it smoothed out. Now let's talk about the results, the car really changed, better torque, it responds better to the gas pedal, and most importantly, the engine runs like a Seiko watch. The engine light hasn't come back on for 4 days now (it used to come on immediately after turning it off). So as a product, I consider it to be truly effective, and even if the light comes back on, I still think the job it does is exceptional.

  1.5 years ago I changed the catalyst due to a problem, and the aftermarket one they installed was third grade and soon it was working worse than the problematic one, so I tried this additive here to see if I could save something. I used half a bottle in a 2-liter pump sprayer, the kind that gardeners and refrigeration technicians have. The "official" L-M pump is exactly the same thing. With the engine at 2500-3000 RPM, you remove the air filter and spray into the intake. The engine had a few stutters and then the diagnostic tool showed some errors because the MAF probably got wet, I blew it with air and it cleaned up. Then, with the OBD diagnostic tool, I saw abnormal SFT and LFT values (fuel mixture adjustment), I disconnected the battery terminal to reset the ECU and they returned to normal.
  Driving the car after cleaning and observing the OBD measurements, I found that the behavior of the catalyst improved somewhat (the waveform of the 2nd sensor 'lambda' became flatter, for those who have studied how injection works - not the mechanics unfortunately). I still have a check catalyst light because the one they put in is the cheapest on the market but it happens less frequently than before. It is very likely that this additive does the job, maybe it doesn't work miracles or cure all situations. It also seemed to me that fuel consumption improved slightly. However, this is not a fuel additive, it is aimed at people who handle tools and know the basics of engines, it requires a little attention.

  I put it in a Passat 1.8 20V (atmospheric 125 horsepower), the car unclogged and it feels like it gained more horsepower, becoming more responsive and powerful! I drive it a lot in the city and it accelerates well.
  Be careful with the correct application in order to see results and avoid damage (this is my personal opinion, I do not sign any contract). Rev the engine to 3,000 RPM, let the car warm up first, and then spray it with a pump, like the ones used for cleaning air conditioners (2 bar or more), onto the throttle in the form of a mist (pay great attention to the MAF and sensors just before the intake, otherwise damage may occur). If nothing happens after a few sprays, gradually increase the RPM up to a maximum of 3,700-4,000, but not for more than 3 minutes continuously, and the car will unclog. Then take a 15-20 kilometer drive on an open road and it's ready.
  Pay attention to nosy neighbors because it will emit a lot of smoke and make noise.

  A week after I installed it, the check engine light came on and after a few days, I changed the lambda sensor, then the catalytic converter.

  I had a problem with the acceleration of my car. After much research, I discovered that it was the catalytic converter. After applying it, the car unclogged and fuel consumption was reduced.

  It does the job. It feels like the car unclogged and pulls better from low speeds.
