Not quite, Theo.

Yes, quite.

In common english usage, "grease" can refer to
solid oils, such as animal fat. But lubricating "grease" is
completely different.

Now you're just trying to be smart. Animal fat has never been inferred,
implied, nor even remotely hinted at in the thread.

It just looks the same, hence the same name.

It doesn't look the same.

As he said, its oil + thickeners.

Correct. Oil *and* thickener/carrier. Nothing else he said was
correct.
