5. Desert Gold CPG
Caterpillar Desert Gold is a heavy duty, premium synthetic, extreme pressure lubricating grease developed for the most extreme operating environments. Desert
Gold is formulated with a high viscosity, synthetic base fluid, polymers and molybdenum disulfide, as well as a high viscosity index and high dropping point.
Caterpillar Desert Gold will protect equipment against heavy shock loads. Desert Gold protects against corrosion in extreme heat, in moist conditions, or in dusty conditions.
This product has excellent characteristics of adhesion and of stability. Caterpillar Desert Gold provides longer protection than other greases. Caterpillar Desert Gold is
an environmentally friendly grease which does not contain antimony, sulfur, barium, zinc, lead, or phosphorous. Normal operating temperatures are -6 to 230°C 21 to
450°F. Caterpillar Desert Gold can operate at higher temperatures for shorter time periods. Caterpillar Desert Gold has additional extreme pressure protection for highly
loaded pin joints.
6. Arctic Platinum CPG
Caterpillar Arctic Platinum is a super-premium extreme pressure lubricating grease developed for lubrication in below zero temperatures to moderate operating
temperatures. Arctic Platinum is available in grades 000, 00, 0, 1, and 2 to ensure flow in central lube systems in a variety of ambient temperatures from -60 to 18°C -76 to
65°F. Caterpillar Arctic Platinum has a high drop point and contains five percent molybdenum disulfide for protection against extra heavy loads. Arctic Platinum
provides excellent protection against corrosion and against oxidation. Caterpillar Arctic Platinum is an environmentally friendly grease which does not contain antimony, sulfur,
barium, zinc, or phosphorous.
Caterpillar Arctic Platinum is designed for long life lubrication of horizontal pivot and lower link bearings, of steering cylinders, of kingbolt bearings, of upper hitch link
bearings and of ejector carrier roller bearings. This grease is extra tacky for retention on excavator carbody bearings. Caterpillar Arctic Platinum has additional extreme
pressure protection for highly loaded pin joints

When you start an engine in ambient temperatures below -20°C —4T or when you
operate a machine in ambient temperatures below -20C -4T, use base oils that can flow in low temperatures. These oils have viscosity grades of SAE 0W or of SAE 5W
MPGL meets the requirements for extended service intervals of automotive chassis points and for extended service intervals of wheel bearings with disc brakes in
automobiles, in vans, in taxi fleets, and in light trucks. This product meets the NLGI certification of GC-LB. 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.
1. Multipurpose Lithium Complex Grease with Molybdenum MPGM
MPGM is a NLGI No. 2 general purpose lithium complex grease that is used for light- duty applications and for medium duty applications. The MPGM is strengthened with a
molybdenum disulfide and with a high molecular weight polymer. These additives strengthen the capabilities of lubrication. The additives also increase the protection to
the parts. The MPGM is strengthened for extra lubrication and for extra protection. MPGM contains unleaded additives. MPGM also contains antiwear inhibitors, inhibitors
for oxidation, and corrosion inhibitors that are for protection and lubrication in many environments. The MPGM is formulated with a high viscosity base fluid and a polymer
additive.
The MPGM has the following features: • Protection against water washout
• Increased retention • Resistance to heavy loads
