Regular lamp oil usually came in clay flasks that could hold up to 1 pint (473 ml) of oil. This amount was sufficient to power most typical lamps and lanterns for 6 hours. If a creature was covered in oil, its flammability increased the efficacy of attacks with fire upon it considerably.
Extremely flammable aromatic oil flowed through fountains in the Temple-Under-the-Sea, located in the Fiddler's Green region of the Sea of Swords. The oil's sweetly sticky saccharine aroma permeated the temple's upper chambers and was used for ceremonial purposes.
