four wheel drive steering knuckles, spring shackles, heavy equipment
pivot joints and other components operating in high-load, low-speed
conditions. NLGI #1 is preferred for cold temperatures and auto
pumping systems. Offers excellent water washout resistance.

PRODUCT DESCRIPTION
AMSOIL GH Series Heavy Duty EP Grease is composed of synthetic base oils and lithium-complex
thickeners that provides the film strength, shear resistance, and mechanical stability critical to high
load protection. This combination excels in high and low operating temperature ranges by
providing excellent oxidation stability, high temperature dropping points and good low temperature
torque values and pumping capabilities. AMSOIL Heavy Duty EP Grease is compounded with
oxidation and corrosion inhibitors, effective oil soluble EP additives and molybdenum disulfide
(moly) solid EP additives for all around protection in severe conditions.

AMSOIL Heavy Duty EP Grease is formulated with a top performing lithium complex thickener
system that provides excellent water resistance as identified by the ASTM D-1264 water washout
test. AMSOIL Heavy Duty EP Grease adheres to metal and is shear stable during severe
mechanical activity, maintaining consistency and providing superior lubrication protection.

PERFORMANCE FEATURES

Moly Fortified for added EP protection
Adhesive and Shear Stable - prevents squeeze out
High dropping point (exceeds 500ºF)
Excellent water-washout resistance
Oxidation and corrosion inhibited

APPLICATION RECOMMENDATION
AMSOIL Heavy Duty EP Grease in grade #1 is recommended for use in manual or automatic
lubricating systems. NLGI #1 (GHB) grease has better mobility and is the preferred choice for
colder applications, automatic lubrication systems with long pumping runs and other applications
(where recommended by manufacturer).
The correct consistency grade of AMSOIL Heavy Duty EP Grease is 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, plain bearings, gears, bushings, wheel bearings, chassis lubrication, universal joints, ball
joints, tie-rod ends, steering knuckles, and heavily loaded pivot pins on mining and off road
equipment such as power shovels, draglines, wheel and back hoe loaders, excavators and
bulldozers. AMSOIL Heavy Duty EP Greases are suitable for use up to 325º F. When operating at
elevated temperatures, frequent regreasing may be required.

AMSOIL Heavy Duty EP #1 and #2 Greases are compatible with many other types of grease.
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 AMSOIL Heavy Duty EP Grease while the
mechanism is in operation. Closely monitor the system for any inconsistencies. Any grease
compatibility questions should be referred to your AMSOIL representative or AMSOIL INC.

APPLICATION MAINTENANCE
Maintaining a clean work environment is important when equipment greasing is performed. Wipe
grease fittings 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.
