Not quite, Theo. In common english usage, "grease" can refer to
solid oils, such as animal fat. But lubricating "grease" is
completely different. It just looks the same, hence the same name.
As he said, its oil + thickeners.

I believe the context of the discussion was grease as used on
bicycles. I don't think anyone was advocating the use of chicken fat
in their bottom bracket. :-)
