Shell Tellus has an extensive range of hydraulic fluids designed to make your hydraulic systems last longer and perform efficiently.

An ideal fluid would have these characteristics:

  • thermal stability
  • hydrolytic stability
  • low chemical corrosiveness
  • high anti-wear characteristics
  • low tendency to cavitate
  • long life
  • total water rejection

There’s a Tellus fluid for the application you need. We go beyond just manufacturing lubricants for the pump, certain Tellus fluids are made to protect the complete system. Our range includes performance tiers for Universal and Specialised applications to meet the demands of modern hydraulics systems.

Some of the Shell Tellus range uses sophisticated gas-to-liquids (GTL) technology to offer advanced, energy-efficient, synthetic hydraulic fluids for mobile and stationary applications, including in construction and plastic injection moulding.

Shell’s GTL Base Oils are the product of 45 years of research, offering superior hydraulic fluids like the Shell Tellus S4 VE range that meets leading OEM approvals.

The Shell Tellus range

Whatever purpose you need your hydraulic fluid for, the Shell Tellus range is designed to offer improved protection against wear, longer oil life, and better system efficiency. Find out more about our extensive range

Introducing Shell Tellus S4 VE

As we discuss in our whitepaper, Hydraulic power efficiency, today’s more compact mobile fluid power systems have smaller hydraulic fluid reservoirs, making them more susceptible to aeration. What’s more, because the fluid volumes are smaller, reservoir residence times can be as short as 30 seconds, leaving little time for air release.

This heightens the risk of cavitation in your equipment’s hydraulic systems, which, in turn, can increase downtime, reduce efficiency and responsiveness while increasing noise levels and boosting the likelihood of pump failure.

Made using advanced GTL technology, Shell Tellus S4 VE synthetic hydraulic fluid delivers up to a 6% improvement in productivity compared to regular mineral oil-based fluids1 while reducing energy losses from hydraulic pumps by 21%2. It also offers a 27% shorter air release time3 to guard against cavitation.

Benefits of Shell Tellus S4 VE

Extended oil life

Beyond simply meeting standard industry and equipment manufacturers’ specification requirements, Shell Tellus S4 VE hydraulic fluid exceeds the 10,000 hours maximum duration that can be measured in the industry-standard turbine oil stability test (TOST)3.

Wear protection

Shell Tellus S4 VE offers that extra protection against the increasing demands hydraulic systems present. When put to the Bosch Rexroth test, which Shell found to stress fluids 13 times more than previous industry standards, Shell Tellus S4 VE showed 4 times less wear compared to the test’s limit based on the pump station weight loss. This hydraulic fluid also demonstrates low oil shearing, avoiding faster component wear and increasing costs of ownership.

Sludge control

Shell Tellus S4 VE demonstrated up to 10 times less sludge in extreme heat compared to a competitor⁴ when put to the ASTM D7873 dry TOST. With less sludge formation caused by high-temperature equipment operating conditions, your hydraulic systems can be more efficient and avoid blocked filters.

Wide temperature range

Thanks to its viscosity index of 160 combined with its robust shear stability and excellent low-temperature fluidity, Shell Tellus S4 VE offers protection from cavitation during cold start-ups and durability when operating at high temperatures. This wide operating temperature range means it can help to increase hydraulic efficiency, and it’s an excellent choice all year round.

Shell Tellus S4 VE specifications and approvals

In the table below, you’ll find the specifications and approvals, as well as the technical data sheets and material safety data sheets for Shell Tellus S4 VE in English – you’ll be able to obtain these documents in other languages from the Shell EPC area.
