Shell Tellus S2 VX 68
Shell Tellus S2 VX 68 is a high-performance hydraulic fluid developed to deliver reliable protection, extended service life and efficient operation in hydraulic systems operating across a wide range of ambient and operating temperatures. Formulated using high-quality Group II base oils combined with advanced additive technology, Shell Tellus S2 VX 68 provides dependable lubrication performance in demanding hydraulic applications. The formulation resists breakdown caused by heat and mechanical stress while helping prevent harmful deposit formation that can reduce hydraulic system efficiency and reliability.
One of the key advantages of Shell Tellus S2 VX 68 is its ability to maintain stable viscosity and lubrication performance across varying temperature conditions. The fluid features a high viscosity index and highly shear-stable viscosity modifiers that help maintain consistent viscosity characteristics throughout the service life of the fluid. This allows Shell Tellus S2 VX 68 to deliver responsive hydraulic performance from cold start conditions through to high temperature, heavy-duty operation. The improved viscosity stability supports accurate hydraulic control and dependable system performance in equipment exposed to changing environmental conditions.
Shell Tellus S2 VX 68 also provides outstanding wear protection for hydraulic pumps and system components. The advanced anti-wear additive system forms a durable lubricating film between metal surfaces, helping prevent wear under high pressure and load conditions. Shell Tellus S2 VX 68 demonstrates strong performance in recognised industry tests and is designed to meet the demanding requirements of modern hydraulic equipment. This protection helps extend the service life of pumps, valves and other critical hydraulic components while maintaining reliable system operation.
Maintaining hydraulic system efficiency is another important benefit of Shell Tellus S2 VX 68. The formulation provides excellent filterability, helping reduce the risk of filter blockage and maintain consistent oil flow throughout the hydraulic system. Shell Tellus S2 VX 68 also offers strong water separation, air release and antifoam characteristics. These properties help ensure efficient hydraulic power transmission while minimising the effects of cavitation and foaming that can reduce system efficiency or shorten fluid life.
Shell Tellus S2 VX 68 is particularly suited for hydraulic systems operating in exposed environments where significant temperature variations may occur. Typical applications include mobile equipment such as excavators, cranes and construction machinery. Shell Tellus S2 VX 68 is also suitable for precision hydraulic systems where stable viscosity control is required and for marine hydraulic systems where ISO HV category fluids are recommended.
Physical characteristics include a kinematic viscosity of approximately 68 mm²/s at 40°C and 10.5 mm²/s at 100°C with a viscosity index of approximately 143. Shell Tellus S2 VX 68 has a density of approximately 0.860 kg/l at 15°C, a flash point of around 230°C and a pour point of approximately −30°C, supporting reliable hydraulic lubrication performance across a wide range of operating conditions.
