Shell Tonna S2 M


Shell Tonna S2 M is specially designed for the lubrication of machine tool slides, tables and feed mechanisms. It features highly refined mineral oils and special additives to enhance the crucial property of adhesion and reduce stick–slip. It is also a fluid you can trust in applications where there is high exposure to soluble cutting fluids, as it separates completely and immediately for longer coolant life and better cutting performance.


Shell Tonna S2 M has been designed to improve the working environments where it is used.

Designed to protect

Protecting components from damage can help to increase your equipment’s service life and maximise your return on investment. Shell Tonna S2 M has been formulated to help protect your slideways, gears, bearings and hydraulic system components from corrosion and wear. It

  • meets or exceeds FZG scuffing test requirements (Institute for Machine Elements Gear Research Centre), which shows its excellent wear protection.

Designed for long oil life

Shell Tonna S2 M has good slideway adhesion characteristics, which restrict its leakage into the cutting fluid sump and reduce consumption. It also helps to maintain uniform working conditions for your machine.

Designed for high efficiency

Your choice of slideway oil can be decisive in managing tramp oils. Better separation between the coolant and the slideway oil enables the slideway oils to be easily removed, thereby limiting the development of bacteria and fungi in the coolant. In the industry-standard test, Shell Tonna S2 M achieved

  • exceptional levels of separation from all types of coolants: synthetic, semi-synthetic and emulsions.


Shell Tonna S2 M meets the requirements of a wide range of industry bodies and equipment manufacturers. ISO viscosity grades available: 32, 68, 220.


Machine tool slideways, tables and feed mechanisms – for use on a wide range of surface materials, including cast iron and synthetic materials Hydraulic and gearbox systems – for good anti-wear performance. (Shell Tonna S3 M should also be considered.) Shell Tonna S2 M 32 and Shell Tonna S2 M 68 are intended for horizontal slide lubrication. Shell Tonna S2 M 220 is intended for vertical slides owing to its higher viscosity grade.

Real-world value delivery

A wide variety of customers has unlocked value by moving to a higher quality machine tool slideway oil. For instance, some have

  • extended coolant sump life by 20%, with the associated product cost savings
  • increased their speed of operations and rightfirst- time machining: one customer reports enhancing margins by $87,000 a year
  • enhanced efficiency through exceptional machining accuracy.


Whatever your needs or application, we can provide a full range of oils and greases, including synthetic, high-performance products and additional services.
