Castrol Perfecto SN 46 Synthetic Gas Turbine Lubricant


Perfecto SN 46 is a synthetic hydrocarbon based lubricant which has been developed for the lubrication of industrial gas turbines, gas compressors and other items of rotating equipment where high temperatures are encountered or where the critical nature of the plant demands a premium lubricant to ensure long life and reliable operation with extended periods between shut-downs.

Perfecto SN 46 has a very high degree of both thermal and oxidative stability which combine to ensure that the lubricating oil system is maintained free from lacquers and deposits especially in the key areas of turbine bearings and scavenge lines, gearboxes (where a high degree of aeration can give rise to oxidation even at moderate temperatures), gas compressor seals and fuel or governor control valves.


Perfecto SN 46 is designed for use as a gas turbine lubricant. Its major advantages over mineral oils are particularly demonstrated in its ability to protect equipment during extremely cold weather starting, extended high-temperature operation, and where the unit is subject to severe heat soaking after shutdown. Other notable features are excellent wear and rust protection, controlled rubber swell and prevention of sludge or deposit formation.

Meets the requirements of:-
BS 489:1989, DIN 51515 Part 2,
Alstom HTDG 90117,
General Electric GEK 28143A, GEK 32568G, GEK 101941A,
Siemens MAT 812106, Siemens TLV 9013 04 and 05,
Solar ES 9-224U and
MAN Turbo SP10000494596.

Perfecto SN 46 is compatible with other synthesised hydrocarbon fluids and with mineral oils. It is not compatible with synthetic ester gas turbine lubricants or with phosphate ester hydraulic control fluids


Castrol Perfecto SN 46 Synthetic Gas Turbine Lubricant Advantages:

  • High resistance to oxidation and additional load-carrying performance for geared turbines
  • The highly stable formulation ensures a long oil life and minimises the risk of sludging or lacquering even in areas exposed to high temperatures, severe aeration and low oil flow. This prevents the premature failure of critical components such as servo valves which are the susceptible parts of the lubricating oil system. This stability maximises the availability of equipment and minimises maintenance activities during shutdown periods.


All packages should be stored under cover. Where outside storage is unavoidable drums should be laid horizontally to avoid the possible ingress of water and damage to drum markings. Products should not be stored above 60°C, or exposed to hot sun or freezing conditions.
