GP MARGEN Turbine Oil series are supreme performance turbine oils specially designed for use in geared
and non geared steam turbines, gas turbines and combined cycle gas turbines (CCGT) including the gas
turbines operating at high temperatures. These oils are formulated with high quality severely
hydroprocessed API Group II base oils and a proprietary ashless additive package containing anti-oxidants,
FZG booster, corrosion inhibitors and metal deactivators. These oils possess outstanding thermal and
oxidation stability, good load carrying capacity, excellent water separability, superior rust and corrosion
inhibition, low foaming tendency, good air release properties and resistance to chemical degradation to
provide excellent equipment protection, reliable operation, with reduced down-time and extended service
life. These oils exceed the performance requirements of major gas and steam turbine manufacturers.


 Features & Benefits:
Outstanding thermal and oxidation stability prevents sludge formation, controls deposits and minimises
oil degradation leading to reliable operation
Superior anti-wear property and load carrying capability provide excellent protection for geared turbines
Excellent water separation capability resists formation of emulsion and leads to easy removal of excess
water from the lubrication system
Effective rust and corrosion inhibitors provide long term protection to critical system components
Good air release properties and foam control avoid erratic operation and pump cavitation leading to
trouble free operation
