Anti-frictional additive for transmission oils. Getriebeoil-Additiv. Properties. The additive, based on Molibdenum Disulphide (MoS2), is specially intended for use in manual gearboxes and differentials. It significantly reduces wear and temperature at friction areas. So, you can observe softer gear shifting, smoother and quieter gearbox performance with less heating during operation. When the additive is added in old gearboxes and differentials, their performance is significantly improved thanks to smoothing tooth profile, gear shifting becomes much softer and efficiency increases. MoS2 increases performance reliability of the unit and the quality of its operation. Application. For axles and gearboxes of cars operating at high temperatures and loads. Due to the friction reduction effect, the additive is not applicable for automatic transmissions and limited slip differentials. Depending on the level of unit loading, the additive is calculated for 1 - 2 liters of transmission oil.
