Shell Turbo Oil GT
High Performance Industrial Gas Turbine Lubricant
 
Shell Turbo Oil GT has been developed for the most severe operating conditions imposed by modern, heavy duty industrial gas turbines.

Applications
•  Power and industrial heavy duty gas turbines Shell Turbo GT is used as lubricating oil for main shaft bearings and mechanical gears as well as governor oil in the turbine control valves in modern gas turbines.
•  Further industrial applications Shell Turbo GT may also be used for other industrial applications requiring a high
performance gas turbine oil, such as the lubrication of turbo compressors.

Advice on applications not covered in this leaflet may
be obtained from your Shell Representative.

Performance Features and Advantages

•  Outstanding oxidation stability The lubricant's service life depends, to a great extent, on its oxidative stability.  Excellent results
in both the 'hot oxidation test' (FTM5308) and the 'TOST' life test (ASTM-D943) clearly demonstrate 
Turbo GT’s potential for extended service life compared to conventional mineral oil technology.

•  Excellent thermal stability Higher bearing temperatures which are particularly severe during stop/start cycling
conditions, may lead to bearing deposits and the formation of harmful sludge in the system which subsequently may result in expensive “downtime” and reduce service life of system components.
Shell Turbo GT gives greater protection against thermal degradation and may hence significantly contribute to lower operating and maintenance costs.

•  Extra high viscosity index Shell XHVI base fluid has inherently better viscosity/temperature characteristics compared to
standard mineral oils. Shell Turbo GT remains shear stable in service because no “VI” improvers
have been added. The high viscosity index of Shell XHVI gives the benefit of the fluidity of an ISO VG 32 grade oil at
start-up temperatures but higher viscosity compared to conventional oils at higher operating temperatures. 
 
•  Excellent air release characteristics Effective air release with a minimum of foaming tendency as required by modern gas
turbines.
 
•  Low friction properties Shell XHVI base oil has shown a friction reducing effect in main bearings, resulting in
less generation of heat and lower bearing temperatures. This will reduce the chance of deposit formation in the bearing.

Specification and Approvals
Shell Turbo GT greatly exceeds the requirements from major turbine manufacturers specifications including:
•  ISO 6743/5 ISO-L-TGB / -TGC DIN 51515-1, 51515-2 SIEMENS TLV 9013 04 ABB HTGD 90117S GEK 32568E SOLAR ES 9-224 U Class I
