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

This product works as advertised. Just remember it may take a couple of tanks of gas for this to fully work. Put it in my tank ran a tank didn't see any improvement but by the end of the second tank the check engine light was out and has not come back on. I now use this product every couple of months to make sure that I don't end up with a clogged up catalytic converter. Definitely a more economical solution than replacing a catalytic converter.

Absolutely worked! I was skeptical at first, but given the high price alternative of replacing my catalytic converter I decided to give this a try. After a full tank of gas I ran through, the check engine light turned off and has not returned. It’s been at least 4 tank fuel ups with no check light or problem. Would definitely recommend!

Was able to past my inspection, had an error on CAT, one bottle worked. Been driving 55mph trying to hold for 3 mins for about a week and it still did not work, put this in to my tank tried again and passed. Comes in a durable can and the attachment is a huge plus since my car had a capless fuel opening, this was able to bypass the clamps to open out my fuel intake. Very simple to use, but be careful this stuff is not safe to smell very strong fumes. Good value for the money.

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

No effective on my 2017 Tundra Used as directed Next step replace cat system

It worked! Had a Cat code that kept coming be back within 30 minutes after clearing it multiple times, added two cans to a 1/4 tank of gas on a 31 gallon gas tank, didn't fill up again until it was almost empty, fixed, no codes and passed state inspection, good for another year!!!

My 2015 F250 did have an engine light on and AutoZone said the code was the catalytic may gone bad or your truck just needs to be driven hard to blow everything out. I rode it hard, the engine light went off and everything was working fine. Then the next day, to be safe I purchase this to make sure it doesn't return. When it arrived my gas tank was 1/2 full and I put the whole bottle in it. (I have a 34 gal tank) About 5 miles down the road my truck wouldn't go over 40 miles an hour. Then 3 different warning codes went off. I put more gas in it to dilute it but I am still have the same issues. It wont go over 40 miles an hour.
