AMSOIL Synthetic Anti-Wear Hydraulic Oils

Synthetic Anti-Wear Hydraulic Oils
ISO 15, 22, 32, 46, 68 (AW)

Protects hard-working hydraulic systems from the stress of high-pressure, high-load and heavy-duty operations. Remains fluid in cold temperatures for immediate cold-weather flow. Special anti-wear additives and rust inhibitors provide optimum protection to expensive equipment.

AMSOIL Synthetic AW Series Antiwear 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 prevent acid formation and viscosity increase and inhibit rust and foam (providing smooth hydraulic operation). AW Oils contain a very effective zinc-based antiwear/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. AW 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. They are designed for long life and typically reduce maintenance costs by extending drain intervals and reducing labor costs, repairs and downtime.

AMSOIL Synthetic Base Oil Technology

AMSOIL synthetic base oils resist thermal and oxidative breakdown and work to prevent carbon and varnish deposits. The very high viscosity indices, low pour points and lack of paraffins (wax) make these good all-season lubricants well suited for high and low temperature extremes. At high temperatures and pressures, AW Oils provide a good lubricating film and protect components against wear. During cold-temperature operation, equipment starts easier and the need for preheating with sump heaters is reduced. The AW Series base oils also readily separate from water, preventing oil/water emulsions that inhibit lubrication and allowing for longer lubricant life and easier water drainage from the sump.

Performance Features

• Extended oil drain intervals
• Antiwear protection for high-pressure systems
• Recommended for gear, vane and piston pumps
• Contain rust, oxidation and foam inhibitors
• Designed for extreme temperature operations
• Hydrolytically stable and readily separates from water
• Improves mobile equipment efficiency (mehf)

Application Recommendation

The correct viscosity grades of AMSOIL Synthetic AW Series Antiwear Hydraulic Oils are recommended for high- and low-pressure gear, vane and piston stationary and mobile hydraulic systems. They meet the performance requirements of all major hydraulic manufacturers and are excellent for general purpose use where extended drain intervals are desired and in severe duty operations where temperature extremes are encountered. Because they are light-bodied and possess very good cold-temperature properties, AWF and AWG are the preferred choices for temperatures below -20°F.

Some applications include machine tools and presses, mobile construction equipment, farming equipment, logging trucks, boom trucks and plastic injection molding machines. The appropriate viscosity grades of AW Oils are also suitable for use in pneumatic tools and spindles.

AMSOIL AW Series Oils are compatible with hydraulic system seals, petroleum hydraulic oils and most synthetic hydraulic oils*. For optimum performance, it is recommended the system be thoroughly drained and, if warranted, cleaned prior to installation. Oil analysis is recommended to maximize oil drain intervals.

* Not compatible with phosphate ester or silicone fluids.
