Manual gearbox oil additive to restore operative parameters, reduce noise and vibrations, facilitate gear shifting, reduce energy loss and thus save fuel consumption. Suitable for all types of manual gearboxes including semi-automatic ones as they use the same type of torque transmission mechanism. MGSB compound is compatible with all brands of transmission oil. It is chemically neutral and doesn’t change oil properties. HOW IT WORKS Tribotechnical compound contains particles of the active mineral. Being in transmission oil they time to time get into the local zones around a point of surfaces’ contact. There are a high local pressure and the temperature which exceeds 1000 °C. In those conditions mineral get able to activate metallic bonds, which let the surface to capture and attach metal microparticles from the oil. Gradually, a solid metal protective layer is formed on the entire worn surface. The mineral itself remain in the oil and initiates restoration process in other points. The protective layer is hard and smooth, which reduces friction. It also has a porous structure with a large number of micro-hollows. They are filled with oil, which forms a continuous film due to surface tension forces. This oil film is never completely separated from the surface of the part, does not flow down even during a long idle time. The protective layer itself can withstand heavy loads due to microhardness and microelasticity compared to the factory surface. Restored shape and effective lubrication allow the parts to perform their functions as it was laid down in the design of the unit, which improves performance parameters of the whole mechanism.
