My New Gear Oil Appears To Have...Metal Particles In It?

[toomanyxjs]

I realize that headline is ignorant, but look at this:



I've got MOTUL 85W95 GL4/GL5 gear oil in a bottle upside down; there's a brass fitting with a tube on it feeding my differential. Surely that GL5 isn't disintegrating that fitting that quickly, is it?

I'm so confused.

In my tube they were bubbles.

From where I'm sitting,
looks like air-bubbles to me.

Agreed with the others. Looks like tiny air bubbles.

It's not air; these things are tumbling down the tube in a way that air doesn't. Here's another video.

Your gear oil is in a plastic bottle.
If you sit the bottle on a table (and wait overnight)), does it have a pile of metal chips at the bottom ?

I'd put some of gear-lube on a piece of 'white' plastic and inspect with a magnifying-glass or microscope.

I'll check. I do wonder if that brass hose fitting is just... disintegrating. I've heard GL5 can do that, but MOTUL denies it, and it doesn't really pass the sniff-test that it would happen THAT quickly.

Thank you! This place is amazing. I've been wanting to write a deep-dive on it.

Make sure you let everyone know your conclusion.

If the oil was attacking brass it wouldn't cause it to flake off. It would turn the brass surface brown. I agree with bubbles and the suggestion to let the fluid settle and see if the particles float the the bottom or float to the top.

bubbles or some sort of additive fallout.. that will likely be reabsorbed after it gets a few heat cycles on it.

Its unproven that its "metal" and brass would discolor it doesnt turn it into tiny shiny particles... even if you somehow found unbuffered gear oil.
or a poor gear oil such as lucas.

tiny bubbles......in my wine.....makes me happy........makes me feel fine.....

It turned out to be a poorly manufactured brass fitting on my bottle. Tons of little bits of brass in its bore.

I know; it sounds insane, but it is absolute trash.
