PRODUCT DESCRIPTION
AMSOIL
Synthetic High-Viscosity Grease (GVC) is a
lithium-complex-thickened grease blended with
premium ISO-320 synthetic base oils. This grease
is fully compounded with additives providing EP
protection, oxidation resistance and rust and
corrosion protection. AMSOIL High-Viscosity
Grease is shear stable, maintaining its
viscosity and consistency in the presence of
mechanical activity. It also stays in place by
resisting water washout. During high-temperature
operation, AMSOIL High-Viscosity Grease’s
thickener system remains intact and the
high-viscosity base oils resist thermal
breakdown, providing a thick film for good
boundary lubrication protection. AMSOIL GVC
adheres to critical components in severe
conditions to provide problem-free operation,
resulting in increased uptime and reduced repair
and maintenance costs.
APPLICATION
AMSOIL Synthetic
High-Viscosity Grease is excellent for use in
heavy-duty industrial and off-road applications
where equipment operates under adverse
conditions, including exposure to environmental
elements, slow, heavily-loaded applications and
shock-loading conditions. AMSOIL High-Viscosity
Grease is formulated to excel in wet
applications requiring excellent water
resistance and in high-temperature applications
up to 177ºC (350°F) in continuous service and
204ºC (400°F) in intermittent service. The
lithium-complex thickener system and
high-viscosity base oil provide top performance
in hostile environments and heavy-duty
industrial or offroad applications where typical
multi-purpose greases may not perform up to
standards.
AMSOIL
High-Viscosity Grease is compatible with many
other types of greases. However, it is
recommended that when changing greases the
equipment be cleaned of the old grease when
possible or flushed with a liberal amount of the
new grease while the mechanism is in operation.
Closely monitor the system for any
inconsistencies. Any grease compatibility
questions should be referred to your AMSOIL
representative or AMSOIL Technical Services.
APPLICATION MAINTENANCE
Maintaining a clean
work environment is important when equipment
greasing is performed. Wipe grease fittings
clean prior to injecting grease to prevent
contaminant ingestion. Maintain bearing housings
one-third to onehalf full of grease. Prevent
over-greasing as this can result in excessive
heat buildup. Supplement standard grease
maintenance by periodically cleaning and packing
housings with fresh grease on an established
maintenance schedule.
