High Performance Hydraulic Fluid, Group II Base Oil Technology, Versatile Applications
Shell Tellus S2 VX fluids are high performance hydraulic fluids based on Group II base oils that provide
outstanding protection and performance across a wide range of temperatures. They resist breakdown under heat
or mechanical stress and are ideally suited to most mobile equipment and other applications subjected to a wider
range of ambient or operating temperatures.
Long fluid life – maintenance saving
Shell Tellus S2 VX 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 VX 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.
Highly shear stable viscosity modifiers help minimize variations in the fluid properties throughout the service life of the fluid
Outstanding wear protection
Tellus S2 VX is designed to meet the demands of hydraulic systems well in to the future, including 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 VX 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 VX 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
Mobile/exterior hydraulic systems
Hydraulic and fluid power transmission systems in exposed
environments can be subject to wide variations in
temperature. The high viscosity index of Shell Tellus S2 VX
helps deliver responsive performance from cold start
conditions to full load, severe duty operation.
Precision hydraulic systems
Precision hydraulic systems require excellent control of fluid
viscosity over the operating cycle. Shell Tellus S2 VX
provides greater temperature-viscosity stability compared to
ISO HM fluids that can help improve the performance of
such systems.
Marine hydraulic systems
Suitable for marine applications where ISO HV category
hydraulic fluids are recommended.
