Graphite and molybdenum are used in lubricating oils to reduce the coefficient of friction. The crystalline structures create sliding properties on metal surfaces, which support emergency running properties, especially in the event of oil losses and extreme loads. At that time, for example, colloidal graphite was required in the oil of the drive components of a BMW R68. Available in 15ml tubes. Addition recommendation in gear oils: manual gearbox 3%. Drive axles 5%.
