Copper, nickel, and ferric (III) oxide catalyze the oxidation of mineral oils, quickly turning them into sludge. Copper and ferric (III) oxide are used to accelerate oxidation in laboratory bench tests used to grade mineral oils for service. Copper and nickel are both used in the tri plate typically applied to AR buffers; some ferric (III) oxide is created from steel wear particles in an AR. Oil cans are typically made from chromium plated steel. Chromium does not catalyze the oxidation of mineral oils to prevent rancidivation in storage.
It is likely that the batch of RemOil that Revdrshad used did not have adequate oxidation stability, which is derived from additives. Anyone's guess whether this is typical. Branded mineral oil blends are frequently resourced, except for those made by the majors.
The reason that I ask is that I have a Browning semi 30.06 that the bolt was stodgy in cold weather. I took it to a gunsmith 5 years ago, maybe more, to have it cleaned thoroughly.
This deer season the bolt did not slam shut for the second round. Luckily, I am such a precise shot that the second shot is never needed.
When I got home, I used a degreaser and removed SLUDGE from the side of the action in probably some inside too.
Rem oil remnants?
I used CLP and I can shoot as many deer as I can now until the smoke gets too thick to see.

I guess I would call it "sludgy and discolored." It reminded me of an old bottle of vegetable oil, where you get a ring of dried goo around the cap. What I got was a ring (from the back of the BCG) on the surface/face of the buffer. Which was sticky and discolored. (darker brown, instead of lighter tan/yellowish.)
This was, coincidentally right after a distant friend was talking about "How Remoil will go rancid on you."
I could never explain it as well as 10x25mm did, but I can tell you it was an all factory Armalite from 1997. So, as far as I know, just a blued finish BCG.
That rifle typically sits in my safe, but I'll try and take a look at it in the next day or so... Maybe shed some more light on it.
It seems the Lucas I put on the "Sludged" BCG/buffer all but eliminated the stained and sludgy Remoil. So pictures didn't seem necessary.
Either way, I decided years ago the Remoil was junk. Ymmv.
