AMSOIL SG Series Extreme Pressure Gear Oils are
long-life, extended drain premium gear oils. AMSOIL SG Oils incorporate
the highest quality shear-stable, synthetic fluids, resulting
in extended operational temperature ranges and superior hydrolytic
stability and thermal oxidative resistance. AMSOIL Synthetic SG
Series Extreme Pressure Gear Oils are the primary recommendation
for gear applications requiring an extreme pressure lubricant.
Superior film strength, EP and antiwear protection
Outstanding thermal, oxidation and hydrolytic
Positive seal and petroleum oil compatibility
Excellent rust, corrosion and foam prevention
Excellent wear and shock loading protection
Extended oil drain intervals
Unbeatable cold-temperatur performance
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.
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

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
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.
* 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
** 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
AMSOIL SG Gear Oils are not recommended for automotive
hypoid gear applications.
