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
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.
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.
Outstanding wear protection
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.

Maintaining system efficiency
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.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.
Main Applications
Industrial hydraulic systems
Shell Tellus S2 MX fluids are suitable for a wide range of hydraulic power applications found in manufacturing and
industrial environments.

Maintaining system efficiency
Marine hydraulic systems
Suitable for marine applications where ISO HM category hydraulic fluids are recommended.
