Shell Tellus S3 M 46

Zinc-free hydraulic fluid for industrial, marine, and mobile systems

  • Zinc-free additive system delivers advanced wear protection under low and severe duty

  • Long fluid life with ≥5000 hours in ASTM D943 TOST test

  • Maintains filterability and performance even when water-contaminated

  • ISO 4406 cleanliness rating of 21/19/16 or better from Shell filling lines

  • Excellent water separation, air release, and foam control properties

  • Compatible with standard hydraulic pump systems and mineral oil fluids

  • Low toxicity to marine and freshwater invertebrates

  • Formerly known as Shell Tellus S3 M

Global Product Code: 001D7759



Application:

Shell Tellus S3 M 46 is a high-performance ISO VG 46 zinc-free hydraulic fluid designed for extended service life, superior wear protection, and system efficiency. It is well-suited for demanding industrial, marine, and mobile hydraulic systems where conventional fluids degrade prematurely or maintenance access is limited.

Performance Features & Benefits:

  • Extended Oil Life: Designed for a minimum 5000-hour lifespan in the ASTM D943 TOST oxidation test, offering reduced downtime and maintenance.
  • Advanced Wear Protection: Zinc-free anti-wear additives provide strong protection in both low-load and high-load operating conditions, validated in Denison T6H and Eaton Vickers 35VQ25 pump tests.
  • Consistent Hydraulic Efficiency: Maintains system performance through excellent water separation, air release, and anti-foam behavior, even with water contamination.
  • System Cleanliness: Delivered at ISO 4406 21/19/16 cleanliness or better, supporting filtration and component longevity.
  • Environmental Responsibility: Classified as ‘not harmful’ to aquatic invertebrates; zinc-free formulation and low sulfur base oils reduce environmental impact.

Main Application Areas:

  • Industrial manufacturing hydraulic systems
  • Marine hydraulic systems
  • Mobile hydraulic equipment with ISO HM fluid specifications
  • Severe duty operations requiring extended fluid life

Specifications & Approvals:

  • Denison Hydraulics (HF-0, HF-1, HF-2)
  • Fives Cincinnati P-70 (ISO 46)
  • Eaton Vickers (Brochure 694)
  • ISO 11158 (HM fluids)
  • DIN 51524-2 (HLP oils)
  • ASTM D6158 (HM mineral oils)
  • SS 15 54 34 M

Environmental & Safety Information:

  • Not likely to present health hazards when used as recommended and with good personal hygiene.
  • Use appropriate protective gloves when handling used oil. Wash thoroughly after contact.
  • Do not discharge into drains, water, or soil. Return used oil to designated collection points.
  • Safety Data Sheet (SDS) available via inquiry
