I have continued to be curious why people that know nothing would
say things about which they know nothing. Grease and wax asr ONE
chemical chain from being the same thing. Where the hell do you
get Candle Wax from - TALLOW - which is animal fat. The
lubricating grease on a new chain (SRAM no longer put this grease
on a chain) is petroleum based but the chemistry is the same.

It's difficult to tell who or what you're talking about, given your

But to discuss a matter of fact: "Where the hell do you get Candle
Wax from - TALLOW - which is animal fat" has been wrong for normal
commercial candles for well over 100 years. See

Some people still make or value tallow candles. Those are mostly
the sorts of people who weave their own wool to make their own
clothes, raise their own chickens, and tell time using only
sundials. Heck, they probably use downtube friction shifters!

A mechanical engineer I worked for who's specialty is monitoring
machine vibrations for the purpose of predictive or proactive
maintenance, explained to me that lubricating grease is made from a
mix of a "soap" and oil, and is not a blend of wax and oil.  Seems
about right...

Yes that's right, usually using lithium or calcium based binders.

Put another way, the lithium or calcium is an element of the soap (salt
of a fatty acid).  Typical household soaps have sodium or potassium in
the same role.
