Liqui Moly Car Maintenance Cleaners And Fluids (‎300G)

its good to use it every 50k km since the catalyst always contains the surface of carbon and this cleaner moves a part of its surface; its good to let a professional do it directly to the catalyst but if it is hard to spend time in the mechanic you can add one bottle every 50k it will be very helpful for your car life.

I used before and repeated again since it achieves perfect results

I’ve tested the Liqui Moly Car Maintenance Cleaner multiple times, and it has consistently performed well in addressing minor engine issues. After using it, the check engine light turned off, which was impressive and provided quick relief. However, the effect seems to be temporary, as the check engine light usually returns after a month or two. This product is great for short-term maintenance or as a quick fix, but it may not resolve underlying engine problems completely. Overall, it’s a handy solution to have, especially if you’re looking for a simple and effective way to manage minor engine issues.
