Servoline oils provide good oiliness for general lubrication of machinery even under boundary lubrication conditions. These products maintain a thin film of oil under light and medium loads and provide protection against corrosion and rust even during idle periods. Servoline oils are recommended for all types of industrial machinery using once-through lubrication systems. Also recommended for use in the lubrication systems of machine tools, textile machinery and other machine parts which are lubricated by a thin film of oil. Heavier grades of Servoline oils can be used in the lubrication of small open gears under light duty conditions where oil is applied intermittently by means of an oil can.
