Industrial 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.
Applications
Industrial hydraulic systemsShell Tellus S2 MX fluids are suitable for a wide range of hydraulic power applications found in manufacturing and industrial environments.
Mobile hydraulic fluid power transmission systemsShell 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.
Marine hydraulic systemsSuitable for marine applications where ISO HM category hydraulic fluids are recommended.
Performance & benefits
Long fluid life – maintenance savingShell 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 protectionTellus 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 efficiencyExcellent 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.
Standards & approvals
Bosch Rexroth Fluid Rating RDE 90245
Bosch Rexroth RDE 90245 — hydraulic fluid rating list
Bosch Rexroth's list of hydraulic fluids rated for use in its own pumps and motors. A fluid is listed after passing wear testing on axial piston pumps.
Parker Denison HF-0
Parker Denison HF-0 — hydraulic fluid, most severe level
The most severe level of the Denison hydraulic fluid specification: the oil must pass the wear test on both a vane pump and a piston pump, dry and in the presence of water. HF-0 subsumes HF-1 and HF-2.
Parker Denison HF0/HF1/HF2
Parker Denison HF-0, HF-1 and HF-2
The three Denison hydraulic fluid levels quoted together. An oil covering all three passes the vane pump and piston pump tests alike, including in the presence of water.

Eaton (Danfoss) E-FDGN-TB002-E — hydraulic fluids
The same hydraulic fluid technical bulletin, quoted under the Danfoss name after the acquisition of Eaton's hydraulics business.
ISO 11158 (HM fluids)
Hydraulic oil, type H (HM fluids) — ISO 11158
The international standard for mineral hydraulic fluids; class HM is the antiwear oil, the ISO counterpart of DIN 51524-2 HLP.
DIN 51524 Part 2 HLP type
Hydraulic oil Part 2 HLP type — DIN 51524
Part 2 of the German hydraulic fluid standard: HLP oils — mineral oils with oxidation, corrosion and antiwear additives. It is the most widely quoted reference in industrial hydraulics.
Swedish Standard SS 15 54 34 AM
SS 15 54 34 — environmental requirements for hydraulic fluids (Sweden)
The Swedish standard requiring high biodegradability, low aquatic toxicity, and that the finished fluid not be classified as environmentally hazardous. It is required near groundwater and drinking water sources; verified products appear on the "SP list".
