Mobil Glygoyle SCF Series


Mobil Glygoyle SCF lubricants are custom formulated lubricants designed for use in rotary screw compressors. The specially designed polyglycol basestock of the Mobil Glygoyle SCF lubricants limits dilution by hydrocarbon and other compressed gases making Mobil Glygoyle SCF particularly well suited for harsh chemical environments. The use of Mobil Glygoyle SCF allows up to 20 maximum wt. % hydrocarbon dilution. Mobil Glygoyle SCF is formulated withProprietary components designed to prevent rust and corrosion in the presence of H2S as well as to control oxidation and foam.

Product series information

Features and Benefits

Mobil Glygoyle SCF is a custom-blended Polyglycol (PAG) synthetic lubricant specially formulated to offer excellent performance in demanding gas compressor applications. Formulated with a PAG polymer basestock, Mobil Glygoyle SCF is designed to exceed the capabilities of petroleum-base and many synthetic-base lubricants in this severe service application. The excellent oxidative and thermal stability of Mobil Glygoyle SCF helps to assure long service life in high temperature operations. Their inherently high viscosity indexes, (>200), facilitate low temperature startup and help maintain acceptable viscosity over a wide temperature range. Mobil Glygoyle SCF lubricants have outstanding lubricity. Mobil Glygoyle SCF is designed with additive technology that provides enhanced protection against wear, oxidation, corrosion and foam. Polyalylene glycols are highly stable even at sustained high temperatures and thus have very low deposit-forming tendency. Any decomposition products that may form are soluble in the lubricant and do not tend to separate as sludge or contribute to the formation of varnish or lacquer.

Mobil Glygoyle SCF lubricants offer the following potential features and benefits:

  • Outstanding severe-service performance
  • Good thermal stability to control deposit formation
  • Exceptional control of sludge, varnish, or lacquer formation
  • Good resistance to hydrocarbon dilution
  • Good resistance to hydrocarbon wash-off
  • Good Water resistance at high temperature (>70°C)


Mobil Glygoyle SCF is a premium lubricant/coolant designed for process and gas rotary screw compressors. It is recommended for use in sour gas compressor applications where severe heavy hydrocarbon dilution may occur. Mobil Glygoyle SCF fluids are well suited for low specific gravity gas compression in low ambient temperature conditions.

Mobil Glygoyle SCF lubricants are also recommended for use in rotary screw, vane and reciprocating compressors in industrial applications where thermal stress on the lubricant is a concern and high viscosity fluids are required.

Mobil Glygoyle SCF lubricants are designed to be very effective in combating corrosion and promoting long life in sour hydrocarbon gas compressors.

Mobil Glygoyle SCF lubricants are compatible with many common elastomers and seals used in current compressor systems. Compatibility should be checked by consulting the equipment manufacturer.
