Hydraulic Fluids Experience
Extreme Temperature Changes
At start-up in cold temperatures mono-grade
hydraulic oils or low viscosity index hydraulic oils
can be too thick. This can cause the following:
1. Hydraulic action is greatly diminished causing
sluggesh operation or none at all.
2. Hydraulic pumps can become oil starved and Pump
wear or failure can occur.
Hydraulic Fluids Experience
Extreme Temperature Changes
At hot operating temperatures mono-grade or low
viscosity index hydraulic oils can be too thin. This
can cause the following:
1. Hydraulic pumps can suffer wear, increased heat and
possible pump failure.
2. Hydraulic operation can become erratic and unsafe.
3. Hydraulic pumps become very noisy.
4. Increased heat can cause shortened oil life.
Why Switch from Mono-Grade
Hydraulic Oils to AMSOIL
mehf?
Operators are sometimes forced to change from ISO
22 in the winter to ISO 100 in the summer in order
for their hydraulic systems to operate properly.
By using AMSOIL mehf hydraulic oils (AW Series)
operators can use one fluid year round with
increased efficiency from productivity and/or fuel
savings in mobile equipment.

In this example, the efficiency gained by using
AMSOIL in place of the two mono-grade oils is
greater than 15%. This increase in efficiency can be in
the from of increased production or from fuel savings
in mobile equipment or a combination of both.
AMSOIL AW Series mehf Fluid Provides the Following
1. Extended oil drain intervals without having to
switch from winter grade to summer grade
hydraulic fluids.
2. Fuel savings in mobile equipment
3. Increased production
4. Increased pump and system life
5. Less downtime
