High Performance Hydraulic Fluid, Group II Base Oil Technology, Industrial Applications
Shell Tellus S2 MX fluids are high performance hydraulic fluids based on Group II base oils that provide
outstanding protection and performance in most manufacturing and many mobile equipment operations. They
resist breakdown under heat or mechanical stress and help prevent damaging deposit formation that can
decrease the efficiency of your hydraulic power system.
Performance, Features & Benefits
Shell Tellus S2 MX fluids are formulated for exceptional
foam control and excellent air release to facilitate efficient
hydraulic power transfer and minimise fluid and equipment
impacts of cavitation induced oxidation that can shorten fluid
life.

Long fluid life – maintenance saving
Shell Tellus S2 MX fluids help extend equipment maintenance intervals by resisting thermal and chemical
breakdown. This minimizes any harmful sludge formation and provides better reliability and system cleanliness.
Main Applications
Shell Tellus S2 MX fluids also have good stability in the presence of moisture, which ensures long fluid life and
reduces the risk of corrosion and rusting, particularly in moist or humid environments.

Industrial hydraulic systems

Outstanding wear protection
Shell Tellus S2 MX fluids are suitable for a wide range of hydraulic power applications found in manufacturing and
industrial environments.
Tellus S2 MX is designed to meet the demands of hydraulic systems well in to the future, including new specifications such as Bosch Rexroth Fluid Rating RDE 90245 and enhanced extreme pressure performance in the FZG test (FLS 11 at ISO VG 32). It also demonstrates excellent performance in the tough Denison T6H20C (dry and wet
versions) and the demanding Eaton Vickers 35VQ25. Shell
Tellus S2 MX fluids can help system components last longer.

Mobile hydraulic fluid power transmission systems
Shell Tellus S2 MX fluids can be used effectively in mobile hydraulic power applications such as excavators and cranes,except where significant ambient temperature variations are encountered. For these applications we recommend Shell Tellus S2 VX.
Maintaining system efficiency
Marine hydraulic systems
Suitable for marine applications where ISO HM category
hydraulic fluids are recommended.
Excellent filterability and high performance water separation, air release and antifoam characteristics all help
contribute to maintaining or enhancing the efficiency of hydraulic systems. Optimization of friction characteristics also helps reduce harmful stick-slip effects.
An oil cleanliness particle count of ISO 4406 20/18/15 or better (measured at the point of filling) helps reduce the impact of contaminants on filter blocking, allowing both extended filter life and enhancing equipment protection.
