Liqui Moly MoS2 Leichtlauf 10w-40 Engine Oil is a semi/part synthetic engine oil designed to enhance engine performance and longevity. It features a low-friction formulation combined with MoS2, a solid lubricant that forms a robust film on metal surfaces, providing exceptional wear protection and efficient oil penetration. This unique solid lubricant creates a high-load protective film on all metal surfaces, significantly reducing wear and tear, which contributes to an extended engine life and enhanced reliability during operation. The specially engineered low-friction formulation allows for quick oil penetration during start-up and reduces friction while driving, ensuring smoother operation.
