Sacred oil is a vial of blessed olive oil that is used to make pyre logs. It is obtained from the Shades of Mort'ton minigame, by using vials of Olive oil on the fire altar, once the temple has been fully repaired and the altar lit. Converting olive oil to sacred oil costs sanctity points, which are gained by repairing the temple's walls or by killing the loar shades that attack the temple. Each dose of olive oil costs about 0.9% sanctity to convert; a 4-dose vial of olive oil will cost about 3.6% sanctity to convert into sacred oil. Additionally, players must have at least 10% sanctity in order to convert olive oil into sacred oil.

Sacred oil's sole use is to create pyre logs, which may be used to cremate the remains of various shades. Pyre logs are made by adding sacred oil to logs, which grants between 12 and 16 Firemaking experience per set of logs, depending on the tier of logs used. Additionally, different logs require different amounts of sacred oil, with low-end logs requiring 2 doses and high-end logs requiring 4 doses. If you haven't completed the Shades of Mort'ton quest, you will not be able to use sacred oil to create pyre logs.

Cremating shade remains in Mort'ton is necessary to obtain various keys that allow access to the Shade Catacombs and the reward chests within. In both cases, Firemaking and Prayer experience are gained in the process.
