Description
Advanced Lubrication for Gearbox Longevity
Würth Gearbox Performance Improver is a high-performance additive concentrate designed to upgrade the protective and lubricating qualities of manual gearbox oils. Its OMC² technology forms a strong lubricating film that reduces metal-to-metal contact, minimises wear, and ensures smooth gear operation under high load conditions.
Enhanced Protection and Performance
By stabilising viscosity and slowing oil ageing, the improver extends the service life of gear oils and protects gearbox components against corrosion, wear, and deposit formation. The result is a gearbox that remains cleaner, more efficient, and better protected for longer.
Improved Driving Comfort
Drivers benefit from smoother and more precise gear shifts, while unwanted gearbox noise caused by friction is significantly reduced. This makes it not only a protective solution but also an enhancement to driving quality.
Preventative and Curative Application
The product can be used preventively at each gear oil change or repair, as well as to address problems such as gearbox noise or shifting difficulties.

- Warm up the gearbox oil by running the engine.
