Mobil industrial , Australia

Premium Quality Lubricant for Reciprocating Natural Gas Compressors

Product Description

Mobil Pegasus Compressor Oil 264 has been specifically formulated from  highly refined paraffinic base oils and high performance additives to provide excellent performance in reciprocating natural gas compressors. It is formulated for outstanding cylinder and piston ring lubrication, excellent oxidation resistance, and excellent chemical tolerance.


Features and Benefits

Outstanding cylinder and piston ring lubrication.


The unique combination of additives protects against separation of dispersion-type additives in lubricator reservoirs, as well as downstream separators and chillers.


High temperature stability and excellent oxidation resistance contribute to low sludge and deposit formation.


Chemical tolerance - Mobil Pegasus Compressor Oil 264 has improved tolerance to contamination by hydrogen sulphide, amines, glycols or other scrubber solutions.


Reduced sight glass staining of compressors equipped with automatic lubricators.



Mobil Pegasus Compressor Oil 264, for natural gas service, is ideal for initial break-in of compressor cylinders and packings.Its use should continue for 300-500 hours while the lubricated components attain a high polish. Thereafter, its use may be discontinued in "sweet" and "dry" gas service if a lower viscosity is acceptable to the compressor manufacturer. If the gas being compressed is sour, wet, or contaminated with scrubber solution, Mobil Pegasus Compressor Oil 264 should continue to be used rather than an engine oil type lubricant. In this way, dilution by condensates can be tolerated while a satisfactory viscosity is maintained.
