  • Formerly known as Shell Tellus EE

Global Product Code: 001D7768



Application:

Shell Tellus S4 ME 68 is a premium synthetic ISO VG 68 hydraulic fluid engineered for energy savings, long service life, and superior equipment protection. Suitable for high-pressure hydraulic systems, including plastic injection moulding machines and metal press operations, it ensures reduced energy consumption and outstanding reliability. Previously marketed as Shell Tellus EE.

Performance Features & Benefits:

  • Energy Efficiency: Demonstrated 1–4% energy savings in practical applications through optimized flow and frictional behavior.
  • Extended Oil Life: Surpasses 10,000 hours in TOST oxidation stability testing, allowing significantly longer oil change intervals.
  • Superior Wear Protection: Delivers up to 68% less wear in Vickers V104C pump test compared to OEM pass/fail criteria.
  • Clean and Stable Operation: High resistance to sludge, varnish, valve sticking, and oxidation. Supplied at ISO 4406 cleanliness level 21/19/16 or better.
  • System Compatibility: Works with most mineral oil-based fluids and standard hydraulic pump components, seals, and coatings.

Main Application Areas:

  • High-pressure industrial systems such as plastic injection and metal pressing
  • Mobile and marine hydraulic systems requiring excellent low-temperature properties
  • Systems exposed to thermal or contamination stress requiring high oxidation resistance
