How much is petrol per litre?
'Litro' — 'LI-tro'. Two syllables; stress on the first. 'Al litro' means 'per litre'.
Ask when the price display is unclear, or to compare prices between two nearby stations before committing.
'Quanto costa al litro' uses the preposition 'al' (a + il) before 'litro'. 'La benzina' is petrol. In Italy, fuel prices are displayed on large boards at the entrance to every station — this question is more often rhetorical.

Italian fuel prices are among the highest in Europe due to heavy excise taxes. Prices at motorway ('autostrada') service stations are significantly higher than at roadside stations. Always fill up before entering a motorway if possible.
