PRODUCT DESCRIPTION
AMSOIL Synthetic Multi-Purpose Grease grade #2 is recommended in manual or automatic
lubricating systems.

NLGI #2 (GLC) is the preferred choice for medium to high ambient temperatures, sleeve type
bushings, high shock loading environments, wet environments and wheel bearings and other
automotive applications.

The correct consistency grade of AMSOIL Synthetic Multi-Purpose Grease is recommended in
heavy and light duty applications found in manufacturing plants, automobiles, agricultural and
construction equipment.

These include, but are not limited to, roller bearings, plain bearings, thrust bearings, gears, electric
motors, presses, winches, bushings, wheel bearings, chassis lubrication, universal joints, ball joints,
tie-rod ends, and steering knuckles. AMSOIL Synthetic Multi-Purpose Greases are suitable for use
up to 350 degrees F. When operating at elevated temperatures, frequent regreasing may be
required.

AMSOIL Synthetic Multi-Purpose Greases are 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 Multi-Purpose Grease while the mechanism
is in operation. Closely monitor the system for any inconsistencies. Grease compatibility questions
should be referred to your AMSOIL representative or AMSOIL Inc.

APPLICATION RECOMMENDATION
AMSOIL GLC Greases grade #2 is recommended for use in manual or automatic lubricating
systems. NLGI #2 (GLC) is the preferred choice for medium to high ambient temperatures, sleeve
type bushings, high shock loading environments, wet environments. and is the primary choice for
wheel bearings.

The correct consistency grade of AMSOIL GL multi-purpose greases are recommended for use in
heavy and light duty applications found in manufacturing plants, automotive applications,
agricultural equipment and construction equipment. These include, but are not limited to, roller

bearings. chassis lubrication, universal joints, ball joints, tie-rod ends, and steering knuckles.
AMSOIL GL greases are suitable for use up to 350 F When operating at elevated temperatures,
frequent regreasing may be required.

AMSOIL GL Lithium Complex Greases are 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 GL grease while the mechanism is in operation.
Closely monitor the system for any inconsistencies.   Please ask us about any grease compatibility
issues.

APPLICATION MAINTENANCE
Maintaining a clean work environment is important when equipment greasing is performed. Wipe
grease fitting clean prior to injecting grease to prevent contaminant ingestion. Maintain bearing
housings one-third to one-half full of grease. Do not over-grease, as excessive heat buildup can
result. Supplement standard grease maintenance by periodically cleaning and packing housings
with fresh grease on an established maintenance schedule.
