PRODUCT DESCRIPTION
AMSOIL Synthetic Water
Resistant Grease is an
extreme-pressure,
multipurpose grease
formulated specially for
wet-duty performance. Its
water washout and spray-off
resistance are ideal for
wheel bearings of vehicles
and trailers frequently
exposed to water, mud, snow
or ice. It is also excellent
for use in plants, such as
paper mills, in which
machinery undergoes frequent
or prolonged exposure to
water.
Water Washout and
Sprayoff Protection
AMSOIL Synthetic Water
Resistant Grease derives its
superior wet-duty
performance from its
peerless cohesiveness and
adhesiveness. It holds
together when exposed to
water and clings tenaciously
to metal surfaces when wet.
Components remain protected
during prolonged exposure to
standing water or exposure
to pressurized water.

Rust and Corrosion
Protection
AMSOIL Synthetic Water
Resistant Lithium Complex
Grease protects metal
surfaces from rust and
corrosion, both of which may
be hastened or worsened by
frequent or prolonged water
contact. It seals metal
surfaces against rust and
chemically fights corrosion.
High and Low Temperature
Performance
AMSOIL Synthetic Water
Resistant Grease effectively
reduces friction, helping
high-speed components run
cooler. It resists the
damaging effects of high
temperatures and oxidation
so components stay
deposit-free for optimal
performance and long life.
AMSOIL Synthetic Water
Resistant Grease may be used
in place of separate
high-temperature and
low temperature greases.
Load Carrying and Extreme
Pressure Performance
AMSOIL Synthetic Water
Resistant Lithium Complex
Grease protects components
from metal-to-metal contact
even under heavy loads. Its
extreme pressure additives
form a shield against
sustained or sudden extreme
loads for dependable
protection against wear.
Service and Shelf Life
AMSOIL Synthetic Water
Resistant Grease resists
oxidation, high temperature
degradation and additive
depletion so effectively, it
may be used for longer
service intervals than
conventional greases. AMSOIL
Synthetic Water Resistant
Grease also resists oil
separation and offers a long
shelf life.
APPLICATION
AMSOIL Synthetic Water
Resistant Grease meets the
highest performance
standards set by the
National Lubrication Grease
Institute (NLGI), GC for
wheel bearing applications
and LB for chassis
applications. It may be used
in automotive wheel
bearings, chassis or other
applications for which an
NLGI No. 2 GC or LB grease
is recommended. Its unique
water resistant formulation
makes it ideal for use in
components or equipment with
frequent or prolonged water
exposure. AMSOIL Synthetic
Water Resistant Grease is
compatible with most seal
materials and most other
greases.
