PRODUCT DESCRIPTION
AMSOIL Synthetic Water Resistant Grease (GWR) is an extreme-pressure, multipurpose grease
formulated specially for wet-duty performance. Its water washout and sprayoff 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
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
AMSOIL Synthetic Water Resistant Grease meets the highest performance standards set by the
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.
