AMSOIL Extreme Pressure
Gear Oils
Synthetic SG SERIES
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 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.
