Community-reported petrol, diesel, home heating oil, and green diesel prices across County Donegal. From Letterkenny and Inishowen to the Gaeltacht coast and the Donegal Highlands.
Donegal is the most northwesterly county in Ireland and shares a long, winding land border with Northern Ireland on its eastern and southern flanks. Getting into or out of Donegal by road almost always requires crossing Leitrim, Fermanagh, or Derry, which gives fuel-shopping a cross-border dimension that few other counties share. Sterling and Euro exchange rate fluctuations have historically pushed significant numbers of drivers to buy fuel on whichever side of the border is cheaper.
Letterkenny is the county's dominant commercial centre and the hub of its road network. The N13 west to the Gaeltacht, the N56 coastal route through Dungloe and Glenties, and the N14 and N15 south to Donegal Town all radiate from Letterkenny's roundabout system. The town has the county's densest cluster of forecourts. Donegal Town and Bundoran (a significant holiday destination on the Sligo border) both have competitive local markets by county-town standards.
The Inishowen Peninsula, Ireland's largest peninsula, is served by a single main road through Buncrana, Carndonagh, and Malin Head. Stations are spread thinly across the peninsula, and the drive to Malin Head (the most northerly point in Ireland) involves very few options. The same applies to the Donegal Gaeltacht coastline between Gweedore, Falcarragh, and Dunfanaghy, where distances between stations can be significant.
Home heating oil is the dominant domestic fuel across virtually all of rural Donegal. The county has almost no natural gas infrastructure outside Letterkenny. Green diesel supports Donegal's fishing fleet at Killybegs, one of Ireland's largest fishing ports, and the county's sheep and cattle farms in the inland glens.

Open FuelWatch and zoom to your location. Letterkenny has the most competing stations in the county and tends to have the best-reported prices. In remote peninsulas like Inishowen, coverage depends on community reporters who travel those routes, and prices may be higher due to fewer options.
Yes. Donegal drivers near Derry, Strabane, and Enniskillen can sometimes find better prices across the border depending on exchange rates and duty levels. FuelWatch covers both ROI and NI stations, so you can compare before you decide which side to fill up.
Yes. Home heating oil is by far the dominant domestic fuel in rural Donegal. FuelWatch's Home Oil layer covers kerosene depots serving the county. Community reports from Donegal help other residents plan oil purchases, particularly useful when planning ahead for the winter season.
