From Guild Wars 2 Wiki
Burning Oil is a defensive siege weapon placed over the gates of towers, keeps and Stonemist Castle. For keeps and castles it is default to have Burning Oil; for towers it is a Tier 1 structure upgrade. In both cases it requires supplies in order to become operational.
Burning Oil can be used against attacking enemies to cause significant damage. It is very difficult for enemies to approach the gate or use a Flame Ram while the oil pot is manned by a player.
