Just tried this at my last oil change ; 2016 GTI at 40,000 miles. Objectively only time will tell as to long term effectiveness but engine runs noticeably smoother and quieter. I added this to the Liqui Moly 5w40 advanced technology synthetic oil. Have really learned a lot about Liqui Moly products lately - they are cutting edge for all things combustible! Ausgezeinicht!

Sealed bottle and new product, germany quality, i definetly recommend it. As time goes by i will check if Liqui Moly Ceratec has made my engine run smooth and quiet. Thanks a lot for the low price and first class quality product! !!!
