Liqui Moly MOS2 Anti-Friction Oil Treatment pack of 6 — single-dose bottles, reduces engine wear and heat

Liqui Moly 2009 MOS2 Anti-Friction Oil Treatment (pk6) is an engine oil additive that applies a molybdenum disulfide film to moving parts to lower friction, heat and wear while the treated oil remains in use.

This concentrated MOS2 formulation from Liqui Moly is designed to bond to metal surfaces inside petrol, diesel and LPG engines, creating a low-friction boundary layer that tolerates heavy loads and high temperatures. It’s compatible with turbocharged and supercharged units and can be added from the first oil change or used anytime the oil is changed. Each pack contains six single-dose bottles for easy, measured application during service intervals.

How does MOS2 reduce friction and what does that mean for my engine?

Molybdenum disulfide (MOS2) is a solid lubricant that forms a thin, adherent film on bearings, piston skirts and other wear-prone parts. That film lowers the coefficient of friction between metal surfaces, which reduces mechanical abrasion and heat generation under normal and extreme load conditions.

• Creates a resilient low-friction layer on metal contact points
• Helps reduce metal-to-metal wear during heavy loads
• Improves smoothness of engine operation and reduces hot spots

Can I use this treatment in turbocharged or supercharged engines?

Yes — Liqui Moly formulated this MOS2 treatment to be safe for forced-induction engines. The additive is compatible with the oil environment in turbos and superchargers and does not interfere with their normal operation when used as directed.

• Suitable for turbo and supercharged applications
• Compatible with modern engine oils and seals
• Works under high temperatures typical of boosted engines

When should I add this treatment and how much do I use?

Introduce the additive at the first scheduled oil change for new engines or at any regular oil change for used vehicles. The product comes in pre-measured single-dose bottles — add one bottle per specified oil capacity as instructed on the label for accurate dosing.

• Use from first oil change or at any routine change
• Pack of six single-dose bottles for multiple services
• Follow label dosing based on engine oil capacity

What performance differences can I expect after treatment?

You should notice smoother running and reduced mechanical noise when MOS2 forms its protective layer. While results vary with engine condition and driving style, the treatment aims to reduce wear and lower internal temperatures, which can help oil longevity and steady operation under load.

• Smoother engine response and quieter operation
• Lower friction-related heat during heavy use
• Supports oil life by reducing load on the lubricant

Who is this for: Liqui Moly 2009 MOS2 Anti-Friction Oil Treatment (pk6) is intended for drivers, fleet operators and technicians who want an easy-to-use, service-friendly additive to help reduce friction and wear in petrol, diesel and LPG engines — especially vehicles used for towing, performance driving or extended high-load operation. It suits both routine maintenance at home and professional workshops needing repeat dosing options from a six-pack.
