Multipurpose Greases
Multipurpose Lithium Complex Grease
(MPGL)
Multipurpose Lithium Complex Grease (MPGL)
is a general purpose lithium complex grease for
medium-duty applications. This product has good
characteristics at high temperatures such as a
dropping point of 260

C (500

F). MPGL contains
unleaded extreme pressure additives, antiwear
inhibitors, and corrosion inhibitors that provide extra
protection in the following applications:
• Construction
• Agricultural
• Automotive
MPGL meets the requirements for extended service
intervals of automotive chassis points. MPGL also
meets the requirements for extended service
intervals of wheel bearings with disc brakes in
automobiles, in vans and in light trucks. This
product meets the NLGI certification of “GC-LB”.
MPGL is also available in a NGLI No. 2 grade.
Normal operating temperatures for this product are
−
28 to 149

C (
−
18 to 300

F). This product is also
available as a white lithium complex grease.
Multipurpose Lithium Complex Grease
with Molybdenum (MPGM)
Multipurpose Lithium Complex Grease with
Molybdenum (MPGM) is a general purpose
lithium complex grease that is used for light-duty
applications and for medium-duty applications. The
MPGM is available in the following grades: NLGI
No. 2 and NLGI No. 0. The MPGM is strengthened
with a molybdenum disulfide and a polymer for
extra lubrication and protection. MPGM contains
unleaded additives. MPGM also contains antiwear
inhibitors, rust inhibitors, and corrosion inhibitors
that are for protection and lubrication in many
environments. The MPGM is formulated with a base
fluid that has high viscosity.
The MPGM has the following features:
• Increased protection against water washout
• Increased retention
• Resistance to heavy loads
This product is recommended for heavily loaded pin
joints and for journal bearings. This product meets
the certification of “GC-LB”. Normal operating
temperatures for this product are
−
28 to 149

C
(
−
18 to 300

F) for the NLGI No. 0. Normal operating
temperatures for this product are
−
18 to 149

C
(0 to 300

F) for the NLGI No. 2.
Note: If MPGM is not available, use a multipurpose
type grease which contains three to five percent
molybdenum.
Special Purpose Grease (SPG)
Bearing Lubrication (SPG)
Bearing Lubricant (SPG) is available in a NLGI
No. 2 grade with a polyurea thickener. This
grease is recommended for high temperature
antifriction bearings in the following applications:
electric starting motors, alternators, fan drives,
and generators. The Bearing Lubricant (SPG) has
an effective operating range of
−
29 to 177

C
(
−
20 to 350

F).
Water and Temperature Resistant Grease
(WTR)
The Water and Temperature Resistant Grease is
designed for use whenever the following conditions
are a concern: water washout, severe corrosion,
and high operating temperatures. The Water and
Temperature Resistant Grease provides extreme
pressure protection, antiwear protection, rust
protection and corrosion protection. The Water and
Temperature Resistant Grease is an environmentally
friendly grease which does not contain the following
materials: antimony, sulfur, barium, zinc, lead, and
phosphorous materials. The Water and Temperature
Resistant Grease has excellent shear stability. Water
and Temperature Resistant Grease can also resist
breakdown in the presence of water. The Water
and Temperature Resistant Grease works well in
the following applications:
• Construction
• Agricultural
• Automotive
• Industrial
• Marine
This product meets the NLGI certification of
“GC-LB”. Normal operating temperatures for this
product are
−
40 to 204

C (
−
40 to 400

F).
