The word(s) "oil" appears 41 time(s) in 39 verse(s) in Quran in Muhammad Pickthal translation.

(21) And when We decreed death for him, nothing showed his death to them save a creeping creature of the earth which gnawed away his staff. And when he fell the jinn saw clearly how, if they had known the Unseen, they would not have continued in despised toil.

(22) Who, of His grace, hath installed us in the mansion of eternity, where toil toucheth us not nor can weariness affect us.

(23) And afterward, lo! thereupon they have a drink of boiling water

(24) Here is a boiling and an ice-cold draught, so let them taste it,

(25) Through boiling waters; then they are thrust into the Fire.

(26) As the seething of boiling water.

(27) Then pour upon his head the torment of boiling water.

(28) A similitude of the Garden which those who keep their duty (to Allah) are promised: Therein are rivers of water unpolluted, and rivers of milk whereof the flavour changeth not, and rivers of wine delicious to the drinkers, and rivers of clear-run honey; therein for them is every kind of fruit, with pardon from their Lord. (Are those who enjoy all this) like those who are immortal in the Fire and are given boiling water to drink so that it teareth their bowels?

(29) So know (O Muhammad) that there is no Allah save Allah, and ask forgiveness for thy sin and for believing men and believing women. Allah knoweth (both) your place of turmoil and your place of rest.

(30) They go circling round between it and fierce, boiling water.
