Buses and Big Trucks

Millions of buses and trucks worldwide carry heavy loads and passengers through dense city traffic and cross country excursions every day. The engines and drive train in trucks and buses are especially exposed to wear and tear. This is due to constant operation, accumulated mileage and stop and go traffic. The result is lower vehicle performance over time, frequent breakdowns with costly service requirements and lower fuel efficiency.

NanoLub® DE-S4500 Buses & Big Trucks Diesel Engine Oil Additive is a new generation surface-reconditioning nano lubricant for engine oil, Based on a unique patented technology of super strong and lubricious tungsten disulfide WS₂ multilayered nano-fullerene-like particles. These unique multi-layer IF-WS₂ nano-spheres lower friction and heat, thereby reducing mechanical wear. At the same time, contact pressure and shear cause these nano-spheres to release tribofilms that attach to surface asperities and smooth them, thereby extending mechanical efficiency and apparatus life.


Specially formulated to improve performance and lower operating costs in large vehicles: Trucks, Lorries and Buses. Suitable for large automotive Diesel engines. Superior Extreme Pressure (EP) Anti-Friction (AF) and Anti-Wear (AW) properties. Can be used as part of the additives package for fully-formulated ready to use engine oil or as a top up after market product.

Recommended treatment rate is (3%) 30ml per 1 liter of engine oil.
