Shell Omala S3 GP


Shell Omala S3 GP oil provides extreme-load protection and performance for industrial gears. It is designed to help solve problems associated with worn, misaligned and contaminated gears. It is an oil that you can rely on to help prevent foaming and water contamination, which can reduce gear performance under extreme pressure and contaminated conditions.

Designed to protect

Protecting gears from damage can help to increase service life and maximise your return on investment. Shell Omala S3 GP is specifically formulated to protect under shock-load, extreme-load and contaminated conditions. It offers

  • over double the weld load of normal gear oils to enhance protection for shock-loaded, misaligned and contaminated gear sets. It also offers high micropitting resistance, as it passes load stage 10 in FZG tests and the four-ball-test at 500 kg when dry and 400 kg after water exposure.

Designed for long oil life

Limiting fluid degradation can help to prolong oil life. Shell Omala S3 GP is designed to help you operate for longer without interruption – for reduced maintenance requirements and enhanced productivity. In the industry-standard oil life test, Shell Omala S3 GP achieved

  • up to 13% less thickening than the maximum allowed after 312 hours at 121°C (ASTM D2893).

Designed for SYSTEM efficiency

A gear oil needs to protect and lubricate efficiently. Shell Omala S3 GP is designed to increase productivity by helping equipment to meet or exceed its design capabilities. It provides

  • up to 50% faster water separation to help ensure efficient and constant lubrication
  • good foaming resistance when contaminated with solids, as it resists foaming in modified industry standard tests, even with 5wt% cement dust contamination.


Shell Omala S3 GP meets the requirements of a wide range of industrial bodies and equipment manufacturers, and is available in viscosity grades ISO 220,320, 460, 680 and 1500.

Real-world value delivery

Shell has developed and marketed value-adding oils for many years. Shell Omala S3 GP is the latest speciality industrial gear oil designed to solve problems by helping to

  • reduce wear and premature gear failure in heavily loaded and contaminated environments such as those found in the steel, mining and cement industries
  • extend the working life of older or worn gear sets.


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