Manufacturer's description
Premium oil for the gearboxes of industrial steam, gas and combined cycle turbines. Shell Turbo S4 GX 46 is based on GTL (Gas-to-Liquid) technology and has been developed to meet the demands of high-efficiency turbine systems. Designed to deliver outstanding long-term performance while operating under the most severe conditions, Shell Turbo S4 GX 46 reduces wear and the formation of deposits and sludge, even under cyclic peak loading conditions.
Applications
- Industrial and power steam, gas and combined cycle turbines
- Shell Turbo S4 GX 46 is used as the lubricating oil in modern steam, gas and combined cycle turbines, particularly in those requiring improved anti-wear performance to protect overloaded gearboxes.
- Other industrial applicationsShell Turbo S4 GX 46 may also be used in other industrial applications requiring a high-performance turbine oil, such as the lubrication of turbo compressors. Specifications, approvals and recommendations: Shell Turbo S4 GX 46 meets and exceeds international specifications and the requirements of the leading turbine manufacturers, including:
- ISO 8068:2006 L-TSE, ISO 8068:2006 L-TGE, ISO 8068:2006 L-TGF, ISO 8068:2006 L-TGSE
- Shell Turbo S4 GX is approved by Siemens Power Generation, specifications TLV 9013 04 and TLV 9013 05
- Shell Turbo S4 GX meets the Siemens Turbo specifications 1CW0047915 and WN80003798 and report 65/0027.
- Shell Turbo S4 GX meets Siemens Finspong MAT812109.
- GE Oil and Gas – conforms to the specification listed in document ITN52220.04

Performance & benefits
- Delivers exceptional resistance to degradation, even under conditions of high thermal and oxidative stress; excellent results in both the ASTM Dry TOST and TOST Life tests (ASTM D943) demonstrate the potential to offer extended service life, reduced maintenance costs and less downtime compared with mineral oil technology.
- Excellent deposit-prevention capability helps lubricate high-temperature gas turbine bearings with minimal deposit and residue formation, reducing the potential for component failure and the risk of unplanned turbine shutdown.
- As pressure in gearboxes increases, an oil's anti-wear protection becomes critical; it offers enhanced anti-wear protection for heavily loaded gearboxes, helping maintain optimum operating conditions even in challenging situations, without reducing deposit resistance or oil life.
- Demulsibility, air release, resistance to foaming and filter blockage are critical factors for oil in turbine gearbox design, especially for those with a short oil residence time; offers excellent performance in all four areas, ensuring continued operation under optimum conditions.
