Shell Tellus S4 VX
Special Application Hydraulic Fluid
Shell Tellus S4 VX is an advanced hydraulic fluid technology designed for use in applications
subjected to extremely low ambient temperatures such as mining or forestry applications in
arctic or exposed areas.
Performance Benefits
Low temperature system operation ａnd efficiency
The very high viscosity index (VI) of Shell Tellus
S4 VX ensures that the hydraulic fluid flows at
temperatures where conventional hydraulic fluids
would become too thick to allow equipment
operation. This allows safe equipment start-up at
very low temperatures, with no or minimum
heating of the system being required. This delivers
increased equipment availability ａnd more
efficient operation of the hydraulic system, which
in turn, helps users obtain higher productivity from
their machines.
Extremely wide operating temperature range
The very high viscosity index of the fresh fluid,
coupled with mechanical shear stability, allows
operation over a very wide temperature range.
All-year round operation with Shell Tellus S4 VX is
therefore possible (subject to a maximum
operating temperature of 75 oC).
Equipment protection
Shell Tellus S4 VX contains carefully designed
ashless (zinc-free) anti-wear additives to help
protect critical components of the hydraulic system
from wear.
Shell Tellus S4 VX is manufactured with a Quality
System assuring the fluid at the Shell plant filling
lines meets the requirements of max ISO 4406
21/19/16 class. As recognized by DIN 51524
specification, the oil is exposed to various
influences with transport ａnd storage that could
effect the cleanliness level..
Applications
Low-temperature exterior hydraulic applications
Shell Tellus S4 VX has been designed for use in all
types of hydraulic systems where the operating
temperature does not continuously exceed 75 °C.
Shell Tellus S4 VX has been specifically designed for
systems that must be started-up at extremely low
temperatures, with a subsequent temperature increase
during operation, such as mining ａnd forestry
machinery.
Note: Operators are recommended to check with
the equipment manufacturer to determine whether the
viscosity characteristics of Shell Tellus S4 VX are
suitable for use in their application.

Health ａnd Safety
Guidance on Health ａnd Safety is available on the
appropriate Material Safety Data Sheet, which can
be obtained from your Shell representative.
Compatibility
Shell Tellus S4 VX fluids are suitable for use with most
hydraulic pumps.
Fluid Compatibility
Shell Tellus S4 VX fluids are compatible with most
other mineral oil based hydraulic fluids. However,
mineral oil hydraulic fluids should not be mixed with
other fluid types (e.g. environmentally acceptable or
fire-resistant fluids).
Seal ａnd Paint Compatibility
Shell Tellus S4 VX fluids are compatible with seal
materials ａnd paints normally specified for use with
mineral oils.
Protect the Environment
Take used hydraulic fluid to an authorized collection
point. Do not discharge into drains, soil or water.
