Flaming oil is not a range siege weapon, but it has a decent area of effect radius. It can be deployed at any flat enough ground in Cyrodiil and it only requires a small size of space. If a Flaming Oil is placed on flat ground, the oil will be dropped on the ground. If it's placed at the edge of walls, the oil will be dropped off the wall. Flaming oil is very effective in battle of defense. It's good at destroying enemy Battering Rams as well as other siege weapons closed enough, dealing high flame damage over time. Other than that, Flaming Oil is also good at dealing flame damage over time to enemy players, especially vampires.
