The word(s) "oil" appears 22 time(s) in 21 verse(s) in Quran in Muhammad Habib Shakir translation.

(11) Like dregs of oil; it shall boil in (their) bellies,

(12) Like the boiling of hot water.

(13) Then pour above his head of the torment of the boiling water:

(14) A parable of the garden which those guarding (against evil) are promised: Therein are rivers of water that does not alter, and rivers of milk the taste whereof does not change, and rivers of drink delicious to those who drink, and rivers of honey clarified and for them therein are all fruits and protection from their Lord. (Are these) like those who abide in the fire and who are made to drink boiling water so it rends their bowels asunder.

(15) Round about shall they go between it and hot, boiling water.

(16) In hot wind and boiling water,

(17) Then drink over it of boiling water;

(18) He shall have an entertainment of boiling water,

(19) But boiling and intensely cold water,

(20) Laboring, toiling,
