OIL in question

[Neil Morrison]

Historically, vegetable oils and animal fats and oils were the chief sources
of lubricants. Since the late 19th century, more than 90 percent of all
lubricants have been obtained from petroleum or shale oil, which are
abundant and can be distilled and condensed without decomposing (motor oil -
from automobile repair station).

Petrolatum, odorless, tasteless, greasy substance, obtained as the residue
from petroleum after the lighter and more volatile components have been
boiled off. The purified residue is obtained in the form of a yellowish or
decolorized semisolid, known as petroleum jelly, or by various trademark
names, such as Vaseline, and in the form of a clear to faintly yellow
liquid, known as mineral oil. The semisolid form is used as an unguent and
as a base for pharmaceutical ointments; the liquid form is used as a
laxative (mineral oil - from pharmacy).

Regards,

Neil
