Shell Tellus S2 MA 10

Old product name: Shell Tellus DO

Shell Tellus S2 MA 10 is a high-performance detergent-based ISO VG 10 hydraulic fluid designed for industrial systems operating in water-contaminated or solid-particle-laden environments where emulsion-forming, ashless anti-wear fluids are required.

Category:

Shell Tellus S2 MA 10

( Previously named: Shell Tellus DO)

Detergent hydraulic fluid for industrial systems with exposure to water or contaminants

  • High detergency helps disperse solid contaminants and prevent water accumulation

  • Ashless anti-wear formulation offers strong performance in boundary lubrication conditions

  • Excellent corrosion prevention in the presence of water

  • Good resistance to thermal and chemical breakdown ensures consistent performance over time

  • Low-friction additive system reduces stick-slip under high load or poorly lubricated contacts

  • Maintains performance under ISO 4406 21/19/16 cleanliness (ex Shell filling lines)

  • Designed for applications where HLPD-type fluids are specified

Global Product Code: 001D7753



Application:

Shell Tellus S2 MA 10 is an ISO VG 10 industrial detergent hydraulic fluid developed for use in systems subject to contamination by water or particulates. Its ashless formulation provides extra protection in demanding applications where emulsion-forming, detergent-based fluids are preferred. Formerly known as Shell Tellus DO.

Performance Features & Benefits:

  • Protection in Severe Conditions: Detergent and ashless anti-wear technology prevents water build-up and disperses solid contaminants while resisting corrosion.
  • Reliable Equipment Protection: Excellent performance under high-load, low-speed, and boundary lubrication conditions in both hydraulic and geared systems.
  • Consistent Fluid Performance: Resists thermal and chemical degradation, helping maintain oil condition over extended service intervals.
  • System Efficiency: Superior air release and anti-foam characteristics combined with excellent filterability support smooth operation and long equipment life.
  • Clean Operation: Maintains ISO 4406 21/19/16 cleanliness class at filling, as per DIN 51524 requirements (HLPD specification).

Main Application Areas:

  • Industrial hydraulic systems exposed to water and metalworking fluids
  • Injection moulding machinery
  • Mobile equipment operating in contaminated environments
  • Electronically controlled hydraulic equipment
  • Hydraulic systems where HLPD fluids are recommended

Specifications & Approvals:

  • ISO 11158 (HM fluids)
  • ASTM D6158-05 (HM fluids)
  • DIN 51524 Part 2 (HLP fluids)*
  • Bosch Rexroth RD 90220-01 (2011), ISO 22-100
  • Arburg (ISO 46)
  • Mueller Weingarten (ISO 46)

* Meets DIN/ISO specifications except demulsibility, which is not applicable to high-detergency fluids.

Environmental & Safety Information:

  • Unlikely to pose health risks when used as directed and with proper hygiene practices.
  • Use gloves when handling used oil and wash skin thoroughly after contact.
  • Do not discharge into drains, watercourses, or soil. Dispose of used oil at authorised collection points.
  • Safety Data Sheet (SDS) available via inquiry
