Shell Tonna S3 M 68 is an ISO VG 68 grade Slideway Oil.

Shell Tonna S3 M oils are specially designed for the lubrication of machine tool slides, tables and feed mechanisms. Their enhanced tackiness and stick-slip characteristics are combined to offer superior frictional performance on slideways. They are specially recommended in cases where high precision and low speedmachines are used as well as in combined lubrication systems.

Please note that this is a premium slideway oil and is suitable for use on many lathes and milling machine slideways, even where the original manufacturer specifies a different oil. In many cases for old machinery, specific slideway oils were not available when they were manufactured and this oil should be seen as a step up where standard hydraulic fluids such as Shell Tellus were originally specified.
