Purpose and Specifications

LIQUI MOLY Pro-Line Engine Wear Protection is a premium additive that forms a tough lubricating film using molybdenum disulfide (MoS2) on all engine rubbing surfaces. This cuts friction for smoother operation, saves fuel and oil, reduces wear, and boosts reliability in gasoline and diesel engines.

• Key Benefits: Less engine wear, quieter running, lower fuel use, excellent emergency protection if oil runs low.
• Compatibility: Mixes with all motor oils, safe for turbochargers and catalytic converters, no deposits or filter clogs.
• Volume: 1 liter treats up to 25 liters of oil.
• High thermal stability: Works reliably up to engine temps over 150°C.
