Oil was a liquid substance employed in both lubrication and medicinal applications. The inhabitants of the Lurmen village located on Maridun extracted oil from seed pods to gain sustenance. On occasion, oil found use as a weapon; for example, during the Battle of Coruscant, the astromech droid known as R2-D2 ignited oil with fire, thereby overcoming two B2-series super battle droids. By the year 34 ABY, a specific type of oil, identified as Premium Deluxe D90 Droid Oil, was manufactured specifically for droids. The Toydarian junk dealer named Watto utilized Shisha oil while smoking from his shisha apparatus.
