Shell Tellus S2 VX 15
Shell Tellus S2 VX 15 is a high-performance hydraulic fluid developed to provide reliable protection, long service life and efficient performance in hydraulic systems operating across a wide range of temperatures. Formulated using high-quality Group II base oils combined with advanced additive technology, Shell Tellus S2 VX 15 delivers dependable lubrication performance in demanding hydraulic applications. The formulation resists thermal and mechanical breakdown while helping prevent harmful deposit formation that can reduce system efficiency and reliability.
One of the key advantages of Shell Tellus S2 VX 15 is its ability to perform effectively across wide temperature variations. The fluid features a high viscosity index and highly shear-stable viscosity modifiers that help maintain stable viscosity characteristics throughout its service life. This enables Shell Tellus S2 VX 15 to provide responsive hydraulic performance from cold start conditions through to high temperature, heavy-duty operation. The improved viscosity stability supports consistent hydraulic response and improved equipment control under varying operating conditions.
Shell Tellus S2 VX 15 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 15 demonstrates strong performance in recognised industry tests and is designed to meet the demanding requirements of modern hydraulic equipment, helping extend the service life of pumps, valves and other critical hydraulic components.
Maintaining hydraulic system efficiency is another important benefit of Shell Tellus S2 VX 15. The formulation provides excellent filterability, helping reduce the risk of filter blockage and maintain consistent fluid flow throughout the hydraulic system. Shell Tellus S2 VX 15 also offers high-performance 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 performance or shorten fluid life.
Shell Tellus S2 VX 15 is particularly suited for hydraulic systems operating in exposed environments where significant temperature variations may occur. Typical applications include mobile hydraulic equipment such as excavators, cranes and construction machinery. Shell Tellus S2 VX 15 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 15 mm²/s at 40°C and 3.7 mm²/s at 100°C with a viscosity index of approximately 143. Shell Tellus S2 VX 15 has a density of approximately 0.820 kg/l at 15°C, a flash point of around 200°C and a pour point of approximately −42°C, supporting reliable hydraulic lubrication performance across a wide range of operating conditions.
