How Liquid Additives Fight Engine Wear

As the fleet industry knows all too well, wear is a natural enemy for any engine. 

Metal rubbing against metal is the quickest way to wear out an engine. It shortens the service life and drives up repair costs.

One of the products designed to address this problem is LIQUI MOLY. For this purpose the additive specialist from Germany offers two powerful agents: MoS₂ Anti-Friction Engine Treatment and Cera Tec.

MoS₂ Anti-Friction Engine Treatment is a powerful additive for older vehicles today. It was the first product from LIQUI MOLY, when the company was founded in 1957.

This engine oil additive contains MoS2. MoS2 is a solid lubricant, similar to graphite.

“It forms a protective layer on the metal surface, preventing direct contact between adjacent metal surfaces in the engine,” says David Kaiser, Head of Research and Development at LIQUI MOLY. “This is particularly important immediately after starting the engine, before the motor oil has circulated to all points in the engine.”

Moreover LIQUI MOLY MoS₂ Anti-Friction Engine Treatment improves the emergency running properties, ensuring that the engine is protected against pistons seizing up when the lubricating film tears off. MoS2 is black, giving the entire additive a very dark color. When added to the motor oil, it also becomes dark. The motor oil may have the appearance of old, used oil, but, in this case the dark color is a sign for effective wear protection. MoS₂ Anti-Friction Engine Treatment has proven itself in cars around the world for over 60 years.

While MoS₂ Anti-Friction Engine Treatment protects only physically, LIQUI MOLY Cera Tec comes with an additional protection: it contains so-called friction modifiers, which have a smoothing effect on the metal surfaces with which they connect in the microscopic area. And it also contains solid lubricants for physical protection. These consist of microscopic ceramic particles, which give the additive a beige color. They are so small, that they can easily pass through the oil filter. “This double protection makes Cera Tec a highly effective additive, the effect of which lasts for up to 30,000 miles,” says David Kaiser. “This makes it particularly economical to use.” It is the first choice for newer vehicles.

Both additives reduce friction in the engine. This reduces the engine temperature and even lowers fuel consumption a little. Furthermore, the engine is better protected under extreme loads. And, after all, less wear means a lower risk of repair and a longer service life of the engine. David Kaiser: “This means the additives not only protect the car, but also its owner’s wallet.”
