Put in unleaded petrol.
'Piombo' — 'PYOM-bo'. Two syllables; 'io' is a diphthong.
Specify the fuel type to an attendant. In Italy, almost all petrol is unleaded — 'senza piombo' (without lead) is the standard but it is good to say it explicitly.
'Metta' is the formal imperative of 'mettere' (to put). 'Benzina senza piombo' is unleaded petrol — the standard fuel for petrol engines. 'Benzina super' or '98 ottani' is premium grade.
Voglio la benzina da 98 ottani.
I want 98 octane petrol.
Specifies premium-grade petrol for high-performance engines.
Metta il gasolio, è un diesel.
Put in diesel, it's a diesel engine.
Specifies diesel for a diesel car.
GPL o metano? Che differenza c'è?
LPG or methane? What's the difference?
Asks about alternative fuel options common in Italy.
Italy has a high rate of LPG ('GPL') and methane ('metano') vehicles. Many Italian-registered cars are bi-fuel (petrol + LPG). If your rental car has a blue LPG cap alongside the standard cap, always ask before fuelling.
