MOLYKOTE G-3000
Harmonization Code : 3403.19 | Lubricating Preparations (With 70% or More Petroleum Oils) For Automotive and Other Uses
Main features
- Dual-Mass-Flywheel High-Shear Grease
- -40 to 180 deg C Service Range
- 2,200 N Four-Ball Weld Load
Product Description
MOLYKOTE® G-3000 Synthetic Grease is a beige, approximately NLGI 3 grease based on synthetic oil and a lithium-complex thickener for dual-mass flywheels. The product is characterized by high shear and centrifugal stability, an approximately 400 mm²/s base-oil viscosity at 40°C, and a documented service range of -40°C to 180°C with short-term exposure to 220°C. Condition-specific data include a 2,200 N four-ball weld load, a 0.7 mm wear scar under 400 N, SKF-Emcor corrosion rating 0/0, approximately 0% oil bleeding, and 0.6% evaporation after 24 hours at 150°C. The 300°C dropping point is a test result and is not the maximum continuous service temperature.
Key features
- Dual-mass flywheel grease: Synthetic-oil/lithium-complex formulation developed specifically for DMFW lubrication.
- Mechanical stability: ISO 2137 penetration changes from 223 mm/10 unworked to 253 mm/10 after 100,000 strokes.
- Temperature capability: Documented -40°C to 180°C service range with short-term exposure to 220°C.
- Load, wear, and corrosion data: 2,200 N weld load, 0.7 mm wear scar under 400 N, and SKF-Emcor rating 0/0.
- High-temperature retention data: Approximately 0% oil bleeding and 0.6% evaporation after 24 hours at 150°C.

Additional Information
MOLYKOTE® G-3000 Synthetic Grease
A beige, approximately NLGI 3 grease based on synthetic oil and a lithium-complex thickener, developed for dual-mass flywheels. High shear and centrifugal stability, a documented -40°C to 180°C service range, and condition-specific retention, wear, and corrosion data support evaluation for rotational and torsional DMFW duty.
MOLYKOTE® G-3000 Synthetic Grease is formulated for dual-mass flywheel lubrication.

Typical values are not specification limits. NLGI class, penetration, and base-oil viscosity describe different properties and should not be treated as interchangeable.
Temperature, retention, load, wear, and corrosion data
| Property | Value | Unit | Method / condition |
|---|---|---|---|
| Service temperature range | -40 to +180 | °C | Supplier-documented service range |
| Short-term temperature | 220 | °C | Short-term exposure; not continuous service |
| Dropping point | 300 | °C | ASTM D566; test transition, not service limit |
| Flow pressure at -20°C | 675 | mbar | DIN 51805, Kesternich method |
| Four-ball weld load | 2,200 | N | DIN 51350 T.4 |
| Wear scar under 400 N load | 0.7 | mm | DIN 51350 T.5 |
| Degree of corrosion | 0/0 | — | DIN 51802, SKF-Emcor method |
| Oil bleeding | Approx. 0 | % | FDS 791-32/2; 24 h at 150°C |
| Oil evaporation | 0.6 | % | FDS 791-32/2; 24 h at 150°C |
Results are condition-specific laboratory values. The dropping point is not a continuous operating limit, and bench load or wear results do not establish equipment capacity or field service life.
Designed for dual-mass flywheel lubrication
Dual-mass flywheels combine sustained rotation with torsional oscillation. MOLYKOTE® G-3000 Synthetic Grease is documented specifically for this application and is described as having high shear and centrifugal stability, characteristics directly relevant to grease exposed to rotational and oscillatory duty.
Application validation should use the actual thermal profile, rotational speed, oscillation amplitude, contact materials, lubricant quantity, sealing design, and existing lubricant. The -40°C to 180°C service range is separate from the 220°C short-term limit and the 300°C dropping-point test result.
Representative dual-mass flywheel architecture; actual geometry and lubricant placement vary by design.
