Certain hydraulic systems, including those installed in log splitters, skid steers and small tractors, are often
operated seasonally or intermittently, then stored for extended periods. Although checking and changing hydraulic oil
is sometimes an afterthought, fluid maintenance is important to ensure optimum protection and performance and maximum
equipment life.
AMSOIL synthetic hydraulic oils can provide significant benefits and cost savings
over conventional hydraulic oils.
Reduced Heat
The synthetic construction of AMSOIL synthetic hydraulic oils can reduce heat in hydraulic systems, leading to
better viscosity retention; less varnish build-up, oxidation and component wear (including hoses); longer seal life;
and better overall system performance.
Cold-Weather Performance
Mobile hydraulic equipment often sits in the elements while on a job site, causing many conventional hydraulic oils
to thicken in the cold and lead to equipment damage such as excessive pump wear due to cavitation, blown hoses, broken
shafts and extended warm-up times that waste fuel. AMSOIL synthetic hydraulic oils are formulated for better
coldtemperature characteristics than petroleum oils, helping reduce or eliminate many of these issues.
All-Season Functionality
To eliminate some of the problems associated with temperature changes, many mobile hydraulic equipment owners switch
oil viscosities with the seasons. AMSOIL synthetic hydraulic oils are high-viscosity-index formulations that can
eliminate the need for seasonal changes. It's possible to run an AMSOIL ISO 32 or ISO 46 hydraulic oil successfully
year-round in all but the most extreme cold conditions.
Hose Life Preservation
Cold and heat wreak havoc on hydraulic system hoses and seals. Cold, thick fluid can cause pressure spikes and
extremely hot fluid breaks down hoses and seals over time, leading to leaks and wasted hydraulic fluid. The superior
cooling and flow properties of AMSOIL synthetic hydraulic oils help preserve hose integrity.
AMSOIL Synthetic Anti-Wear Hydraulic Oil effectively inhibits oxidation to help prevent acid formation and viscosity
increase, resist carbon and varnish deposits and inhibit rust and foam (providing smooth hydraulic operation). It
contains an effective zinc-based antiwear/ antioxidant additive that 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.
- Maximum cold-temperature performance
- Formulated for long life
- Superior anti-wear protection
- Contains rust, oxidation and foam inhibitors
- Hydrolytically stable and readily separates from water
- Available in ISO 22, 32, 46 and 68 viscosity grades
AMSOIL Synthetic Multi-Viscosity Hydraulic Oil's blend of high-viscosityindex base oils and performance additives
provides all-season protection and reliable operation at a lower cost. Its proven wear resistance and varnish-control
deliver maximum hydraulic system performance and life, and it is additionally tailored to promote energy efficiency and
foam suppression.
- Provides all-season performance at a lower cost
- Reduces maintenance costs
- Resists varnish, viscosity loss and chemical breakdown
- Increases system performance and responsiveness
- Helps reduce energy costs
- Available in ISO 22, 32, 46 and 68 viscosity grades
AMSOIL Biodegradable Hydraulic Oil (BHO) is a premium-performance, ISO 46 hydraulic oil that exhibits high
biodegradability and low aquatic toxicity, along with superior oxidative stability, excellent low-temperature
performance and outstanding results in laboratory and extended-duration pump testing. It contains antioxidants that
prolong oil life and foam inhibitors that help promote problem-free operation.
