AMSOIL Synthetic Anti-Wear AW Hydraulic Oils

Premium Hydraulic Oil

AMSOIL Synthetic AW Hydraulic Oils are shear-stable, long-life lubricants based on high-quality synthetic oil technology. These oils are formulated with a premium additive system that inhibits oxidation to help prevent acid formation and viscosity increase. Special anti-wear additives and rust inhibitors provide optimum protection to expensive equipment and foam inhibitors provide smooth hydraulic operation.

Special Antiwear Oil Additives Control Wear in Hydraulic Pumps

AMSOIL Synthetic AW Hydraulic Oils also contain a very effective zinc-based anti-wear, antioxidant additive which controls wear in high-speed high-pressure vane and gear pumps while meeting the lubrication requirements of axial piston pumps with bronze-on-steel metallurgy.

High Viscosity Index for Outstanding Hot and Cold Weather Hydraulic Fluid Performance

The very high viscosity index (VI) of AMSOIL Synthetic AW Hydraulic Oils allow them to operate over a wider temperature range than other hydraulic fluids. At high temperatures and pressures, these oils do not thin out, providing a tough lubricating film that protects components against wear. Equipment runs cooler, extending the service life of pumps, valves, motors, hoses and seals. These premium hydraulic oils resist vaporization at high temperatures, ensuring fluid integrity and reducing the need to add fluid to the system.

In cold-temperature operations, the lack of paraffin (wax) in AMSOIL Synthetic AW Hydraulic Oils allow them to remain fluid for immediate flow to the pump, better protection and eliminating time and fuel spent on equipment warm up. Their low pour points (the lowest temperature at which oil flows) allow for easier and more dependable cold weather starts and the need for preheating with sump heaters is reduced.

Water in Hydraulic Oil Readily Separates

AMSOIL Synthetic AW Hydraulic Oils readily separate from water. The industry standard test (ASTM D 1404) proves they have excellent demulsifying characteristics to separate out moisture — in most cases AMSOIL Synthetic AW Hydraulic Oils achieved 100 percent separation in 15 minutes. This allows operators to easily drain off unwanted water and prevent unwanted oil water emulsions that inhibit lubrication, allowing for longer lubricant life and easier water drainage from the sump.

Resists Foaming

AMSOIL Synthetic AW Hydraulic Oils are formulated to resist foaming, even if the reservoir level is low. Foamy oils cause spongy hydraulics, rapid lubricant oxidation and increased cavitation. In the industry standard foam test (ASTM D 892), AMSOIL Synthetic AW Hydraulic Oils gave no-foam performance.

Prevents Deposits

AMSOIL's synthetic base oils resist thermal (heat) and oxidative (oxygen) breakdown, preventing carbon or varnish deposits.

Reduces Energy Consumption and Operating Costs Through Longer Hydraulic Oil Life

AMSOIL Synthetic AW Hydraulic Oils increase efficiency and savings on energy, repair and maintenance costs. Studies indicate that synthetic lubricants can reduce energy consumption by as much as 10 percent, while providing clean, problem-free operations and extended oil drain intervals. They can provide service intervals up to 10 times longer than possible with petroleum-based lubricants, reducing labor costs and downtime.

Reduce Costs

AMSOIL Synthetic AW Hydraulic Oils are designed for long life and typically reduce maintenance costs by extending oil drain intervals and reducing labor costs, repairs and downtime.

Improves Mobile Equipment Efficiency

AMSOIL Synthetic AW Hydraulic Oils meet the requirements for Maximum Efficiency Hydraulic Fluid (MEHF) and can lower costs and/or increase productivity in mobile equipment by 6 to 15%. Improved pump efficiency can increase hydraulic power, reduce fuel consumption and improve productivity.

ISO Viscosity Grades and Applications

AMSOIL Synthetic AW Hydraulic Oils are available in six ISO viscosity grades: ISO 15, ISO 22, ISO 32, ISO 46, ISO 68 and ISO 100. AMSOIL Synthetic AW Hydraulic Oils meet the performance requirements of all major hydraulic manufacturers and are excellent for general-purpose use where longer hydraulic oil life is desired and in severe-duty operations where temperature extremes are encountered.

The correct ISO viscosity grades of AMSOIL Synthetic AW Series Anti-wear Hydraulic Oils are recommended for high- and low-pressure gear, vane and piston stationary and mobile hydraulic systems. Some applications include machine tools and presses, mobile construction equipment, farming equipment, logging trucks, boom trucks and plastic injection molding machines. Also suitable for use in pneumatic tools and spindles.

• ISO 32 is the most widely used viscosity grade. Automotive applications typically call for this grade, referring to it as SAE 10w, and it is used in high pressure gear, vane and piston pumps.
• The lighter grades, ISO 15 and ISO 22, although recommended for all-season use, are ideal for arctic applications (temperatures less than -20° F), such as freezers and outdoor mobile hydraulics.
• ISO 46, ISO 68 and ISO 100 are recommended for heavy industry high-pressure systems and circulating systems specifying high viscosity hydraulic oils.

Hydraulic Oil Compatibility and Oil Life

AMSOIL Synthetic AW Hydraulic Oils are compatible with hydraulic system seals, petroleum hydraulic oils and most synthetic hydraulic oils. (They are not compatible with phosphate ester or silicone fluids.) For optimum performance, it is recommended that systems be thoroughly drained and, if warranted, cleaned prior to installation. Oil analysis is recommended to maximize hydraulic oil life.
