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 equipment life, extending drain intervals, and protecting against wear, pitting and rust.

Base Stock Technology
AMSOIL 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 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 antifoam 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.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 gears**, 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 polyglycol-type gear oils. Thorough flushing prior to changeover is required.

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