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.
