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
lowtemperature 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.
