Shell Spirax S6 GXME


Shell Spirax S6 GXME is a unique, fuel-efficient and long-life oil designed to provide the ultimate protection for the latest, heavy-duty manual transmissions and gears. It is specifically formulated with synthetic base oils and additive technology for improved lubrication and lower operating temperatures over longer oil-drain intervals. Shell Spirax S6 GXME is an oil that you can rely on to help protect against wear, pitting, bearing failure and corrosion for reduced maintenance and longer equipment life, and is designed to help improve your vehicle’s fuel efficiency.

Designed to protect

Protecting manual transmissions and gears from wear, pitting and corrosion can help to extend component life and maximise your return on investment. Shell Spirax S6 GXME offers

  • excellent synchromesh compatibility, which exceeds leading manufacturers’ requirements
  • approximately double the gear life in FZG pitting tests compared with a GL-4 reference oil of the same viscosity grade.

Designed for long oil life

Limiting fluid degradation can help to prolong oil and component life. Shell Spirax S6 GXME has exceptional resistance to physical and chemical breakdown, which means that it can go on protecting components for longer. Shell Spirax S6 GXME

  • remains well within the industry oxidation limits after double the normal test period in DKA oxidation tests, thanks to its long-life additives, which enable the oil to keep gears protected and maintain oil performance over extended oil-drain intervals.


Shell Spirax S6 GXME has special frictional properties and high fluidity that reduce power loss, lower the operating temperature and offer higher mechanical efficiency. These properties can help to cut fuel costs for your business.


Shell Spirax S6 GXME has a low chlorine content that makes it easier to recycle. It also has improved seal compatibility for increased protection against leaks.


The benefits of Shell Spirax S6 GXME have been demonstrated through extensive laboratory tests and over 20 million kilometres of field trials. A wide range of industrial bodies and vehicle manufacturers recognises these benefits and approves Shell Spirax S6 GXME. It is available in viscosity grade SAE 75W-80.


Whatever your needs or application, we can provide a full range of lubricants and services, including Shell Rimula heavy-duty engine oils, Shell Gadus greases and the Shell LubeAnalyst oil and equipment condition monitoring service.
