Catalytic Converter Cleaner 7110 Liqui Moly Catalytic-System Cleaner 300 ml. Review: Effective if your catalytic converters are still okay. - Before I knew my catalytic converters were all the way degraded, I had a p0430 code that I wanted to try to eliminate. I read that Liqui Moly's cleaner is effective, so I gave it a try. It worked for a good 1K miles, so if you need to pass emissions, this might work for you. The p0430 returned, but thankfully I don't live in a emissions testing county. If you have any oil leaks, especially valve cover gaskets, do not do the "Italian tuneup", where you drive the hell out of the car with just Liqui Moly in the tank (or just about). That was a disaster and oil mist got on everything, making a manageable situation far worse. Follow the instructions and drive the car as usual. Review: 21 year OEM factory O2sensor is alive again ! - No snake oil here this product is the real deal. I was very skeptical when my 2005 Honda CR-V started throwing the dreaded P0420 code. For about six months, I kept resetting the check engine light, only to have it come back every time. After reading the reviews, I decided to give this product a try. To be clear, it wasn’t an instant fix. I used the entire bottle and ran 93-octane premium fuel as reviews directed. It took about two to three full tank refills before I noticed the difference but eventually the P0420 code disappeared and hasn’t returned. If you’re expecting overnight results, this probably isn’t for you. In my experience, it takes some time to work, but it was well worth the patience. ## Features - Protects the catalytic converter from clogging with soot. - Cleans the injection system and the combustion chamber. - Improves the combustion of the fuel. - Clean engines reduce fuel consumption and therefore CO2 emissions. - Suitable for all gasoline engines with a catalytic converter. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B07Z54MBQ3 | | Best Sellers Rank | #1,139 in Automotive ( See Top 100 in Automotive ) #8 in Fuel System Cleaners | | Brand | Liqui Moly | | Brand Name | Liqui Moly | | Customer Reviews | 4.4 out of 5 stars 3,911 Reviews | | Item Form | Liquid | | Item Volume | 300 ml | | Item Weight | 0.3 kg | | Manufacturer | Liqui Moly | | Material Feature | Non-Toxic | | Material Features | Non-Toxic | | Model Number | 7110 | | Number of Items | 1 | | Part Number | 7110 | | Scent | Basil | | Size | 10.14 Fl Oz (Pack of 1) | | Specific Uses For Product | Automotive motor additive | | Unit Count | 10.14 Fluid Ounces | ## Product Details - **Brand:** Liqui Moly - **Item Form:** Liquid - **Material Feature:** Non-Toxic - **Scent:** Basil - **Specific Uses For Product:** Automotive motor additive ## Images ![Liqui Moly Catalytic System Clean 300 ml 7110.
