Mobil Glygoyle Series
Polyalkylene Glycol (PAG) Gear, Bearing and Compressor Lubricant
Product Description
Mobil Glygoyle Series lubricants are supreme performance gear, bearing and compressor oils designed to
provide outstanding benefits in terms of efficiency, long oil life, and equipment protection. These fully synthetic,
polyalkylene glycol (PAG) lubricants were developed for use under operating conditions beyond the capabilities
of other synthetic lubricants and mineral oils. Their low pour points ensure excellent low-temperature fluidity.
The ISO 150 to 1000 grades are approved for USDA/NSF H-1 food-grade use. The unique formulation is designed
to provide:
– Exceptional EP/antiwear protection for critical equipment components
– A high level of micropitting protection for sensitive gear systems
– Protection against rust and corrosion in-service
– Resistance against foam buildup
– Excellent lubricity inherent to this fully synthetic lubricant
– Low traction coefficient resulting in increased energy efficiency and reduced bulk oil/system temperatures
– Outstanding thermal and oxidative stability to reduce sludge formation and deposits
Features and Benefits
The Mobil Glygoyle Series of fully synthetic oils are specifically designed to outperform mineral and PAO synthetic
lubricants in gear and hydrocarbon gas compression applications. In worm gears, the unique properties of these
oils allows for more torque to be put through the reducer while in many cases lowering the operating oil sump
temperature correlating to longer seal, oil, and gearbox life. Features compared to other mineral, synthetic, and
PAG lubricants:
General: There are various types of PAG base oils. The inherent properties of these oils can differ depending
on the raw materials and processes used in their manufacture. Features that can differ among various PAG oils
include their traction coefficient (energy efficiency), thermal conductivity, and solubility with hydrocarbon oils,
tendency to attract water, and low temperature properties.
High Efficiency: ExxonMobil researchers have selected PAG base oils which provide high levels of energy
efficiency relative to mineral, PAOs, and other PAG oils. This, coupled with an increased thermal conductivity
of about 10% over mineral and PAO oils, leads to lower operating temperatures and longer component life.
Wide Temperatures: The Mobil Glygoyle Series has very high VIs ranging from 170 for the ISO 68 to 285 for
the ISO 1000. This leads to a wide operating temperature range, beyond that of mineral and PAO lubricants.

Rust Protection: PAG lubricants, which are designed to be immiscible with hydrocarbon oils, tend to absorb
water more than mineral or PAO oils. Because of the potential for high water-in-oil levels, care must be taken
to prevent the formation of rust on equipment. Mobil Glygoyle Series oils pass major rust tests such as the
ASTM D665A and Bethlehem Steel rust test parts A/B, and receives 0,0 ratings in the DIN 51802 Emcor rust
test with distilled water. In addition, they show good yellow metal compatibility with a 1B rating in the ASTM
D130 test. Mobil Glygoyle Series is not recommended for use in areas where saltwater contamination is expected.
Foam Control: Foam control is important, especially in boxes that are “Sealed for Life”. Mobil Glygoyle Series
provides excellent results in all three sequences of ASTM D 892 Foam Test.
EP/antiwear: Having the right blend of EP/AW protection is important, especially in worm gears that contain
bronze and other yellow metals. The Glygoyle Series of lubricants show excellent EP/antiwear protection with
typical results of 12+ in the DIN 51354-2 FZG scuffing test, very low cage and roller wear in the DIN 51819-3
FAG FE8 test, and excellent micropitting protection with a result of ›10-high in the FVA 54 micropitting test (ISO

factor situations
Superb thermal and oxidative stability and sludge
resistance as well as excellent antiwear protection
As with other polyglycol-based lubricants, Mobil Glygoyle Series lubricants are not miscible with mineral oils
and most PAO synthetic oils. Mobil Glygoyle Series must not be used as make-up for systems filled with mineral
or PAO synthetic oils, nor should mineral or PAO synthetic oils be used as make-up for systems filled with Mobil
Glygoyle products. Mobil Glygoyle Series are hygroscopic and do not separate from water. Due to their inherent
high specific gravity, water does not drop to the bottom of reservoirs.

Mobil Glygoyle 460 is specifically designed for the lubrication of worm gears, especially for heavy-duty, severe
service applications, both in food-grade and non food-grade applications. Additionally, the product family has
also proven to be excellent lubricants for all types of industrial gears and anti-friction bearing applications under
severe service conditions. Due to their unique chemical make up, these oils do not typically leave deposits
behind upon reaching oxidative or thermal limitations. This, coupled with the fact that they are not miscible with
hydrocarbons (reduced viscosity dilution), makes the lower viscosity grades especially effective in hydrocarbon
gas compression applications.
The Mobil Glygoyle Series is used for the lubrication of filled for life gearboxes and heavy-duty worm gears,
other industrial gearing in a wide variety of applications, lubrication of plain and rolling contact bearings, and
most types of compressors.
Specific applications include:
• Filled for life gearboxes, especially high ratio/low-efficiency worm gears
• All worm gear applications such as those used in conveyers, escalators, material handling, press drives,
packaging machinery, ski lifts, agitators and mixers.
• Other gear and bearing applications in the cement, metalworking, plastics, food and textile finishing
• Plastic Calendars
• Gas Compression utilizing reciprocation, rotary, screw, and centrifugal type compressors in operating
conditions beyond the capabilities of other synthetic lubricants and mineral oils.
Seal and Coating Compatibility
While Mobil Glygoyle Series oils are compatible
with many seal and coating materials, there is the
potential for substantial variations in the elastomers
and coatings being used today. For best results,
consult your equipment supplier, seal manufacturer,
or your local Mobil representative to verify
