"What's the going price per gallon of sperm whale oil?"

Unless the Braycote products are directly interchangeable with Sperm Whale
oil, how is your comparison even remotely relevant?

They are rendered from entirely different sources. Whale oil is a natural,
animal-derived product that pretty much went out with the depletion of the
resources (and finally, international treaties). P/TFE and MoS2 were
formulated in industrial laboratories, and to this day, are turned out by
industrial processes.

Am I incorrect?
