Shimano Permalub Grease (part number RD10050)

This is a big jar (50 grams!) and very little has been used (see image)

Here is the description of the grease from ChatGPT :

The grease in the image is Shimano Permalub Grease, part number RD10050. It is an OEM (original equipment manufacturer) grease produced in Japan, and here’s what it’s specifically designated for:

Designated Purpose:

Shimano Permalub Grease is primarily used for:

• Internal lubrication of Shimano spinning reel gears, particularly in factory-assembled reels.

• It is often found inside Shimano reels as the factory-applied grease on main gears, pinion gears, and drive systems.

• Designed for long-term lubrication, resisting breakdown over time and minimizing the need for frequent maintenance.

Key Properties:

• Medium-to-high viscosity, optimized for gear meshing under load.

• Excellent adhesion to metal surfaces, reducing the chance of grease being flung off under rotation.

• Stable under heat and pressure, which makes it suitable for heavy-duty usage in both saltwater and freshwater applications.

• Often considered similar to DG-13 or DG-06 in consistency, but formulated specifically for OEM use rather than aftermarket sales.
