Description
AMSOIL SG Series Extreme Pressure Gear Oils are made from
shear stable, high quality synthetic base oils and are fortified with
additives that deliver high performance in industrial gear
applications. These oils are designed to reduce maintenance costs by
extending drain intervals, and protecting against wear, pitting and
rust.
Base Stock Technology
AMSOIL's SG Oils are compatible with mineral
gear oils, synthetic gear oils*, and seals—making
them easy to use. They preserve new seals, prevent leaks, and help
rejuvenate old, brittle seals.
AMSOIL SG synthetic base stocks are inherently resistant to oxidation,
helping provide long life. The naturally high viscosity indices, low
pour points, and lack of paraffins
(wax) make these lubricants ideal for use in wide operating
temperature ranges. At low operating temperatures equipment starts
easier, is not starved of lubrication from channeling and product
solidification, and the need for sump heaters is reduced. At higher
operating temperatures, AMSOIL SG base oils resist the degradative
effects of oxidation that cause poor lubricant performance, and they
maintain an optimal lubricating film between parts.
The base oils utilized are also
hydrolytically stable and they readily separate from water. This
prevents unwanted oil/water emulsions that have poor lubricating
properties and it eases water removal from the sump.
Additive
Performance
AMSOIL SG Oils are fully formulated with sulphur/phosphorous
extreme pressure additives, antioxidants, rust inhibitors, and
anti-foam agents. The SG Oil's thermally stable, extreme-pressure
additive system forms a hard, iron-sulfide coating on metal components.
This iron-sulfide coating prevents
metal to metal contact under boundary lubrication conditions, reduces
friction and protects components against shock loading and wear. The anti-oxidants increase the oxidation
resistance of the synthetic base oils for long, clean lubricant
performance. These oils protect
against rust from water or process contaminants and prevent
foaming, ensuring proper lubrication.

Application Recommendation
AMSOIL Synthetic SG Series Extreme Pressure Gear Oils
are recommended for industrial
applications operating under heavy loads and shock conditions
and specifying an extreme
pressure lubricant. This includes,
but is not limited to, enclosed industrial spur, bevel,
herringbone, helical and worm gear**, chain drives, sprockets and most
metal-on-metal systems requiring extreme pressure additives. These
lubricants are excellent for use in
severe operating conditions and their synthetic properties make
them good all-season lubricants.
The SG
Series Gear Oils meet the AGMA ratings for synthetic gear oils and EP
gear oils and are recommended for use in applications specifying these
standards. Although AMSOIL SG Series Oils are compatible with mineral
oil based lubricants, for optimum
performance it is recommended that the system be thoroughly
drained and, if warranted, cleaned.
The ability
of AMSOIL SG Series Gear Oils to extend drain intervals is subject to operating conditions and
maintenance practices. Monitoring by oil analysis is recommended.
NOTES:
* AMSOIL SG Series Gear Oils, as well as other synthetic
or mineral based oils, are not compatible with poly glycol-type gear
oils. Thorough flushing prior to changeover is required.
** AMSOIL SG Series Gear Oils are not recommended for use
in worm gear or yellow metal containing applications operating at or
above 200°F (93°C). Also not recommended for use in other
applications operating at or above 250°F (171°C). For such
applications, please consult your AMSOIL Dealer or AMSOIL Inc.
AMSOIL
SG Gear Oils are not recommended for automotive hypoid gear
applications.
