Naples has a dense but chaotic fuel network; Eni, IP, Q8, Esso and Tamoil along the Tangenziale and the A1/A3 approaches, with big self-service versus attended price gaps. Official MIMIT data covers the city, so Refuelia shows real prices. LPG and metano (CNG) are both well represented in Campania.
Only 55 of the 581 stations mapped in Naples say whether they sell diesel. The rest probably do; nobody has recorded it. See Naples on the map →
