Even my new G11 DEC axis has this dark grey grease on the gears, and it is smudged on the sides, so 100% sure that's the original color.
The grease under the worm blocks is also this dark grey grease.
Anybody know what this is?
The JetLube MP-50, a molybdenum grease (used at the factory on the worms), is already is a blackish grey color when originally applied. SuperLube which many are using for their relubes, is clearish or slightly off water-white. Any grease will change color over time with use with oxidation and contamination from the metals it contacts. But color is not an indicator of lube degradation, if that is what you are thinking.
No, I am just using the grease color for identification, since I am a big proponent of not mixing greases.? Here's the grease colors that my mount came with:
transfer gears and under the worm blocks : dark grey
on the axis spindle (needle bearings): brownish clear
worm: I dunno the tint, but NOT dark grey
