Venice's road network ends at Piazzale Roma, so fuel stations sit in Mestre and Marghera on the mainland; Eni, IP, Q8, Esso and Tamoil along the A4 and SS11. Self-service is much cheaper than attended, and official MIMIT data covers all sites. There are even floating fuel stations on the Giudecca canal for boats.
Prices in Venice appear when a driver reports one or an official feed carries it, always with the time it was recorded, so you can judge for yourself whether it is still true. See Venice on the map →
