Review:

After troublefree years, using Camguard, I had the opportunity to learn about oiltreatment in deep. After that, I searched for a product, offering the advantages of a modern additive. Finding that, manufactured by the most important additiv chemist, Liqui Moly Germany, I changed to that engine protector.
One point less, because of being more expensive than Camguard. But more modern and even more safe against corrosion.
