Community-reported petrol, diesel, home heating oil, and green diesel prices across County Mayo. From Castlebar and Westport to Achill Island, Ballina, and the remote north Mayo coast.
County Mayo is one of the largest counties in Connacht by land area, and its varied geography creates a genuinely uneven fuel market. Castlebar, the county town, sits at the junction of the N5 (Dublin to Westport), the N60 (to Roscommon and Athlone), and the N84 south to Galway. It has the densest concentration of forecourts in the county. Westport, a busy tourism hub on the coast, has its own competitive local market driven by visitor footfall and the coastal cruise and ferry trade.
The N17 north to Sligo is a significant route through Swinford, Charlestown, and Tubbercurry. Ballina, Mayo's largest town by population, has good fuel provision on the N57 and N26 approaches. These northern towns serve both local residents and traffic heading between Galway and the northwest.
North and west Mayo are a different situation. The drive from Castlebar to Belmullet on the Mullet Peninsula (about 100 km northwest) passes through Crossmolina, Bangor Erris, and a long stretch of blanket bog with very few stations. Achill Island, connected by a bridge to the mainland at Achill Sound, has a handful of local stations that serve the island's residents and a large summer tourist population. Prices at the island's extremities reflect the logistics of island supply.
Agriculture is a major driver of fuel demand across Mayo. The sheep and cattle farms of the Nephin range, the Moy valley, and the plains of south Mayo all require green diesel. Home heating oil is almost universal in rural Mayo outside Castlebar and Ballina town centres.

Open FuelWatch and zoom to your location. Castlebar has the most competing forecourts. In remote areas like Belmullet and Achill Island, far fewer options exist so checking before you leave the main towns is advisable.
Yes. Achill Island stations and those in remote north Mayo like Belmullet face higher distribution costs and fewer competitors. FuelWatch community reports from these areas help other drivers set realistic expectations and plan accordingly.
Yes. Home heating oil is the dominant fuel for rural Mayo homes. FuelWatch's Home Oil layer covers kerosene depots serving the county, including routes through north and west Mayo where oil delivery logistics are more complex.
