Fuel Prices Ireland – Week of 20 April 2026
National Snapshot
If you’ve been keeping an eye on the pump lately, the numbers for the week of 20 April 2026 show a slight easing compared with the high‑inflation months of early 2025. The national average for diesel sits at €2.06 per litre, while unleaded (petrol) averages €1.85 per litre across 562 tracked stations. For most drivers this means a modest saving on the daily commute, but there’s still plenty of room to hunt for a better deal.
Where to Find the Cheapest Diesel Ireland
For those who drive diesel‑powered cars or trucks, the hunt for the cheapest diesel Ireland can be worth the extra few kilometres. Here are the five stations currently offering the lowest rates:
| Station | County | Diesel | Unleaded |
|---|---|---|---|
| Top Oil Charlestown PKD Service Station | Mayo | €1.51 | €1.64 |
| Circle K Express Lifford | Donegal | €1.52 | €1.65 |
| Texaco | Roscommon | €1.64 | €1.70 |
| Inver Castledermot | Kildare | €1.64 | €1.88 |
| Circle K Express Carnew RD Gorey | Wexford | €1.67 | €1.71 |
Those prices are a full €0.30‑€0.50 below the national diesel average, so if you’re passing through any of these counties, it’s definitely worth pulling in for a fill‑up.
County‑by‑County Highlights
While a few out‑of‑the‑way stations deliver rock‑bottom rates, some counties consistently beat the national average. Here’s a quick look at the cheapest counties for diesel (and how their unleaded prices compare):
| County | Avg Diesel | Avg Unleaded | # Stations |
|---|---|---|---|
| Roscommon | €1.79 | €1.75 | 2 |
| Donegal | €1.92 | €1.83 | 7 |
| Cavan | €1.97 | €1.82 | 6 |
| Wexford | €1.99 | €1.85 | 34 |

If you live or work in any of these regions, you’re already paying less than the national average. Meanwhile, Dublin, with 138 stations, remains the most expensive for diesel at €2.09 per litre, though it still offers a respectable €1.84 for unleaded.
