Synthetic SG SERIES Extreme Pressure Gear Oils
Product 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 sealsmaking 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.
