AMSOIL Synthetic Lithium Complex Water Resistant Grease (GWR)

Multi-Purpose NLGI #2 GC-LB Extreme Pressure Fortified. Superior lubrication and protection in automotive and industrial applications with extensive exposure to water.

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.
