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

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!

This stuff actually worked! We put it in our 2014 Silverado 1500 with 200k + miles. It took about 2 weeks of driving though. Probably 2 tanks of gas. Check engine light went out. We had a catalyst code for a month or so before using this stuff.

I dont leave many reviews but it was such a shock it worked after trying so hard to dix this car that i wanted to let people know it work. 2008 750li bmw had code p0430. I tried a few methods to clear code but didnt work. Even tried the gal of paint laquer in the gas tank but no go. To apply the Moly, I used a vacuum line from the intake manifold to suck in the Moly. Tons of smoke from esxhaust, it ran poorly and caused it to stall during the 10 min of applying moly. I thought I ruined my engine it was knocking, sputtering, and lots of smoke. After 20min of easy driving the car came to life, drove better and p0430 code never came back. Know how fast and how much should go into the intake is the tricky thing to know. Each car is different so you needs to figure out your own way to apply the moly.

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.

Works as it should good quality and I didn’t use it for any codes just as a preventative

Here’s the key. Run premium gas in your vehicle a week before. Allow the tank to get down to about 30 miles until empty. Poor entire contents of LM in the tank .Use an OBD to take your CEL off. run your vehicle for 20 miles and then fill up completely with premium gas and you should be in good shape.

Neerd to update to ZERO STARS! Half the bottle went all over my hands because it is a poorly designed spout. Took my car onto the highway with 3/4 tank and this in the tank. Now my car couldn't go over 40mph. It was shaking and whirring and sounds as if it's about to die. FYI - I didn't have any codes. The bottle claims it's preventative to clean out a possibly clogged catalytic converter. I think it just killed my engine. DO NOT BUY. Class action lawsuit!
