 Oil n.  Any one of a great variety of unctuous combustible substances, more viscous than and not miscible with water; as, olive oil, whale oil, rock oil, etc.  They are of animal, vegetable, or mineral origin and of varied composition, and they are variously used for food, for solvents, for anointing, lubrication, illumination, etc.  By extension, any substance of an oily consistency; as, oil of vitriol.
 Note:The mineral oils are varieties of petroleum.  See Petroleum.  The vegetable oils are of two classes, essential oils (see under Essential), and natural oils which in general resemble the animal oils and fats.  Most of the natural oils and the animal oils and fats consist of ethereal salts of glycerin, with a large number of organic acids, principally stearic, oleic, and palmitic, forming respectively stearin, olein, and palmitin.  Stearin and palmitin prevail in the solid oils and fats, and olein in the liquid oils.  Mutton tallow, beef tallow, and lard are rich in stearin, human fat and palm oil in palmitin, and sperm and cod-liver oils in olein.  In making soaps, the acids leave the glycerin and unite with the soda or potash.

From: Easton's 1897 Bible Dictionary

    Only olive oil seems to have been used among the Hebrews. It was
    used for many purposes: for anointing the body or the hair (Ex.
    29:7; 2 Sam. 14:2; Ps. 23:5; 92:10; 104:15; Luke 7:46); in some
    of the offerings (Ex. 29:40; Lev. 7:12; Num. 6:15; 15:4), but
    was excluded from the sin-offering (Lev. 5:11) and the
    jealousy-offering (Num. 5:15); for burning in lamps (Ex. 25:6;
    27:20; Matt. 25:3); for medicinal purposes (Isa. 1:6; Luke
    10:34; James 5:14); and for anointing the dead (Matt. 26:12;
    Luke 23:56).
      It was one of the most valuable products of the country (Deut.
    32:13; Ezek. 16:13), and formed an article of extensive commerce
    with Tyre (27:17).
      The use of it was a sign of gladness (Ps. 92:10; Isa. 61:3),
    and its omission a token of sorrow (2 Sam. 14:2; Matt. 6:17). It
    was very abundant in Galilee. (See OLIVE.)
