Industrial Synthetic Lubricant
AMSOIL SG Series Extreme Pressure Gear Oil is made from shear-stable, high-quality synthetic base oils
and fortified with additives that deliver high performance in industrial gear applications. It is designed to reduce
maintenance costs by extending equipment life, extending drain intervals, and protecting against wear,
pitting and rust.

Base Stock Technology
AMSOIL SG Oil is compatible with mineral gear oils, synthetic
gear oils*, and seals, making it easy to use. It preserves new
seals, prevents leaks and helps rejuvenate old, brittle seals.
AMSOIL SG Oil’s synthetic base stocks are inherently resistant
to oxidation, helping provide long life. Its naturally high viscosity
index, low pour point and lack of paraffins (wax) make it
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 Oil’s base stocks resist the
degradative effects of oxidation that cause poor lubricant
performance, and it maintains an optimal lubricating film
between parts.
The base oils are also hydrolytically stable and readily separate
from water. This prevents unwanted oil/water emulsions that
have poor lubricating properties and eases water removal from
the sump.
Additive Performance
AMSOIL SG Oil is fully formulated with sulphur/phosphorous
extreme-pressure additives, antioxidants, rust inhibitors and
anti-foam agents. The 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
antioxidants increase the oxidation resistance of the synthetic
base oils for long, clean lubricant performance. AMSOIL SG Oil
protects against rust from water or process contaminants and
prevents foaming, ensuring proper lubrication.

Application Recommendation
AMSOIL SG Series Extreme Pressure Gear Oil is recommended
for industrial applications operating under heavy loads and
shock-loading conditions and specifying an extreme-pressure
lubricant. This includes, but is not limited to, enclosed industrial
spur, bevel, herringbone, helical and worm gears**, chain
drives, sprockets and most metal-on-metal systems requiring
extreme-pressure additives. It is excellent for use in severe
operating conditions and its synthetic properties make it a good
all-season lubricant.
SG Series Gear Oil meets the AGMA ratings for synthetic
gear oils and EP gear oils and is ecommended for use in
applications specifying these standards. Although AMSOIL
SG Series Oil is 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 Oil to extend drain
intervals is subject to operating conditions and maintenance
practices. Monitoring by oil analysis is recommended.
NOTES:
*AMSOIL SG Series Gear Oil, as well as other synthetic or
mineral-based oils, is not compatible with polyglycol-type gear
oils. Thorough flushing prior to changeover is required.
**AMSOIL SG Series Gear Oil is not recommended for use
in worm gear applications or applications containing yellow
metal and 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 Series Gear Oil is not recommended for automotive
hypoid gear applications.
