Shell Tonna S3 M


Shell Tonna S3 M is Shell’s top-performing oil specially designed for the lubrication of machine tool slides, tables and feed mechanisms. With excellent frictional properties, very good slideway adhesion and excellent anti-wear performance, it can be relied on to provide efficient machining accuracy and reliable protection for your equipment, especially in highprecision, low-speed machines and combined lubrication systems. It features highly refined mineral oils and special additives to enhance the crucial property of adhesion and reduce stick–slip.

Designed to protect

Protecting components from damage can help to increase your equipment’s service life and maximise your return on investment. Shell Tonna S3 M has been formulated to help protect your slideways, gears, bearings and hydraulic system components from corrosion and wear. In the industrystandard test it achieved

  • up to 92% less wear than the maximum allowed.

Designed for long oil life

Shell Tonna S3 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

Shell Tonna S3 M has exceptional anti-stick–slip properties. In industry-standard tests, it achieved

  • up to 15% less stick–slip than the industry minimum requirement for smoother movement and more-accurate positioning.


Shell Tonna S3 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 Machine tool hydraulic systems – specially recommended for machines that have a combined hydraulic and slideway lubrication system Machine tool gearboxes and spindles, and gear and headstock lubrication Shell Tonna S3 M 32 and Shell Tonna S3 M 68 are intended for horizontal slide lubrication. Shell Tonna S3 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

  • increased machining precision and eliminated stick–slip and jerky movement: one customer reports saving $46,0001 a year in reduced maintenance costs and lost production time
  • reduced oil consumption on slideway applications by up to 65% owing to the oil’s good adhesion to slideways.


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