Megaplex®XD3 (old)

Extreme Pressure Lithium Complex Grease

Phillips 66®Megaplex XD3 is a high-performance, multipurpose, extreme pressure (EP) lithium complex grease developed to satisfy the severe lubrication requirements of construction and off road equipment manufactured by Caterpillar, Komatsu Dresser, Case New Holland, John Deere and others. It is particularly recommended for use in off-highway trucks and heavy equipment, such as bulldozers, motor graders and wheel loaders, operating under heavy or shock loads.

Features & Benefits

• High dropping point (>500°F)

• High load-carrying capacity

• Excellent wear protection

• Contains 3% moly for extra protection against galling and wear under shock loads

• Excellent resistance to water washout

• Excellent resistance to separation

• Protects against rust and corrosion

• NLGI GC-LB certified (Grade No. 1)


• Chassis parts and wheel bearings of construction, mining and other heavy mobile equipment

• Universal joints, constant-velocity joints, brake self adjusting screws and clutch release bearings on off-highway trucks and other heavy equipment

• Tractor-trailer fifth wheels

• Heavily loaded plain and rolling-element bearings in industrial and mobile equipment where the manufacturer specifi es a high temperature, extreme-pressure grease with 3% moly
