To remain competitive, operators are working their hydraulic systems harder for longer, which exerts extra stress on hydraulic oils, including higher operating pressures and temperatures.

At the same time, mobile hydraulic systems are becoming more compact. Their smaller oil reservoirs restrict heat dispersion, which means higher peak oil temperatures. This increases the risk of oxidation and thus sludge and varnish formation. Smaller reservoirs also reduce the fluid residence time needed for the recovery or release of the contaminants that can cause hydraulic system failure. These pressures can differ between industry, application or environment, meaning your fluid selection must be informed by the needs of your equipment.

Fortunately, the Shell Tellus range of hydraulic fluids has been developed with this in mind, so you can select the oil that will deliver optimum value to your specific operations, from construction to manufacturing or mining. Whether working in wet conditions or ultra-low temperatures, high-load requirements or energy efficiency, there will be a Shell Tellus hydraulic fluid to suit your individual equipment needs. For those looking to upgrade energy efficiency and extend oil life, advanced synthetic Shell Tellus S4 VE made with gas-to-liquids (GTL) technology is designed to deliver.

Or, explore our Shell Naturelle range: a selection of environmentally acceptable lubricants and greases (EALs), with a high proportion meeting tough new internationally recognised EU Ecolabel requirements and approved by leading manufacturers, especially suitable for environmentally sensitive applications in forestry, agriculture, mining, construction, power and marine.
