So what is Liqui-moly MoS2?
At Liqui-Moly, it actually all started with this product 40 years ago and today it is still our leading oil additive. MoS2 was originally developed to maintain lubrication in piston-driven aircraft engines in the event of a loss in oil pressure and to prevent complete engine seizure. The incredible low-friction and robust lubrication properties of Molybdenum-Disulfide (MoS2) have been well known for years. The production and patenting of a liquid, additive form of Molybdenum-Disulfide in 1957, was Liqui-Moly’s first product and formed the basis of the company.

So why use MoS2?
For every kilometre you drive you pay with a tiny piece of the engine, because of friction and wear. This can be seen from accumulated metals abrasion in the oil. In spite of all efforts to produce smooth metal surfaces in internal engine components you will find that when examined under a microscope every metal surface looks like the surface of the moon, rough and uneven (as pictured in the below diagram).

How does it work?
Luckily, with LIQUI MOLY MoS2 Friction Reducer this wear can be reduced by smoothing out the inconsistencies in the metal surfaces of pistons and cylinders. By treating the surface with applications of solid lubricants such as molybdenum disulphide you will be able to considerably reduce frictional resistance and wear; chemical agents chemically bond with the metallic surface and smooth the high points of metal pairing surfaces thereby eliminating damage (as pictured in the below diagram).

What are the effects of using MOS2?

As well as being found in a select number of Liqui-Moly oils, liquefied Molybdenum-Disulfide is the active ingredient in Liqui-Moly’s MoS2 Friction Reducer Treatment. Suitable for all road users and numerous non-highway applications, the MoS2 oil additive is specially formulated to significantly extend the life of your engine (especially if it ever suffers a momentary loss in oil pressure), while giving it maximum protection in high-stress, high-load applications, as experienced during towing, off-roading, spirited driving and under racing or competition conditions.

• Substantially reduces wear & extends engine life.
• Less heat, smooth running, reduced fuel consumption.
• Perfect for engines used in high load applications like extended towing and full throttle driving conditions.

Can I use it in my car?
LIQUI MOLY MoS2 Friction Reducer is suitable for all petrol, diesel and LPG engines, safe and effective for all turbocharged and supercharged engines. Can be used in new cars from first oil change, and is effective for the entire period the treated oil is being used in the engine.

How do you use it?
LIQUI MOLY MoS2 Friction Reducer is simply added directly into the oil filler opening of the engine at any stage to reduce the friction and the wear but is most effective when added to fresh oil.
