Etymologically, the entry records: Borrowed from French (essence de) pétrole, from Medieval Latin petroleum, from Ancient Greek πετρέλαιον (petrélaion, “oil of the rock”), from πέτρα (pétra, “stone, rock”)+ ἔλαιον (élaion, “olive oil, any oily substance”). Doublet of petroleum. Root origin matters for spelling because borrowed morphemes (Greek, Latin, Old French, Old English) carry their source-language orthographic conventions into modern English, which is why historical etymology is often the cleanest predictor of whether a cluster like "-ough", "-eau", or "-tion" will appear. For readers arriving here from a spelling check, the authoritative guidance is: the correct English form is petrol, spelled P-E-T-R-O-L, and any other sequence of those letters, regardless of how natural it feels, is a misspelling in standard orthography.
