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.
