Quiet down noisy gearboxes, smoothen notches when shifting, and extend the service life of your drivetrain with Liqui Moly MoS2 Gear Oil Additive.

Formulated in Germany, this highly concentrated additive contains the scientifically proven solid lubricant Molybdenum Disulfide ($MoS_2$). When added to your gear oil, $MoS_2$ forms an incredibly durable, low-friction micro-film on all rubbing and sliding metal surfaces inside your gearbox. This heavy-duty layer cushions gear teeth, lowers operational temperatures, and provides exceptional emergency running properties if gear oil levels ever drop.

Key Features & Benefits

• Smoother Gear Shifting: Substantially reduces internal friction, eliminating notches and stiffness during manual gear changes.

• Quietens Noisy Drivetrains: Cushions worn gear teeth to reduce operational hums, whines, and vibrations in older gearboxes and differentials.

• Reduces Wear & Heat: Keeps oil temperatures lower under heavy loads, safeguarding gears against premature scoring and pitting.

• Emergency Run Protection: The MoS2 coating remains bonded to metal surfaces, providing critical temporary protection even in the event of a sudden lubricant loss.

Application & Dosage Instructions

• Where to Add: Suitable for manual transmissions, transaxles, differentials, rear axles, and mechanical steering gearboxes.

• Dosage Rate: One 50g tube is highly concentrated and treats up to 2.5 Litres of gear oil (a mixing ratio of approximately 2%).

• How to Apply: Simply squeeze the contents of the tube directly into your gearbox or differential filler hole when performing a fluid change or topping up.

⚠️ CRITICAL USAGE RESTRICTIONS — READ BEFORE BUYING:

• DO NOT USE in fully automatic transmissions, DSG/Dual-Clutch gearboxes, or CVT systems.

• DO NOT USE in wet-clutch motorcycle gearboxes (the friction-reducing MoS2 will cause the clutch plates to slip).

• DO NOT USE in Limited Slip Differentials (LSD) requiring friction modifiers, as MoS2 will interfere with the clutch pack locking mechanism.
