Fuel Prices Ireland – Week of 27 April 2026
Weekly Snapshot
This week’s fuel prices Ireland are holding steady, but the numbers still matter to anyone who fills up on a regular basis. The national average for diesel sits at €1.98 per litre, while unleaded (petrol) is €1.83. Those figures come from 483 stations tracked across the island, giving a solid picture of what you’ll pay at the pump today.
If you’re hunting for the cheapest diesel Ireland can offer, a handful of out‑of‑the‑way locations are still pulling ahead of the average. Below, we break down the best bargains and the counties where you’ll generally find lower prices.
Cheapest Stations Right Now
| Station | County | Diesel | Unleaded |
|---|---|---|---|
| Top Oil Charlestown PKD Service Station | Mayo | €1.51 | €1.64 |
| Cork Road (Top Oil) | Cork | €1.54 | €1.74 |
| Circle K Express Shercock | Cavan | €1.67 | €1.77 |
| Maxol Service Station, Moore’s | Donegal | €1.69 | €1.69 |
| Top Oil Kernans Charlestown | Mayo | €1.69 | €1.69 |
These five sites are currently the cheapest diesel Ireland has to offer, and they also give a respectable discount on unleaded fuel. If you happen to be travelling through Mayo or Donegal, a quick detour could save you a few eurocents per litre – and that adds up over time.
Counties With the Lowest Average Diesel Prices
The data shows a clear north‑west advantage when it comes to cheap diesel:
- Donegal – €1.85 (12 stations)
- Cavan – €1.91 (16 stations)
- Louth – €1.93 (16 stations)
- Leitrim – €1.93 (1 station)
- Roscommon – €1.94 (8 stations)
Most of the rest of the country clusters around €1.95‑€2.00 for diesel, with Offaly being the outlier at €2.20. Unleaded averages follow a similar pattern, with the cheapest counties hovering around €1.79‑€1.83.
Practical Advice for Irish Drivers
- Plan your route: If you’re heading west or north, consider topping up in Donegal or Cavan where diesel is below €1.92.
- Watch the pump timing: Prices tend to dip slightly early in the week, especially on Monday and Tuesday. Filling up mid‑week can sometimes shave a cent or two off the national average.
- Use loyalty cards wisely: Many larger chains (Top Oil, Maxol, Circle K) run weekly promotions that stack on top of already low local prices. Keep an eye on their newsletters or in‑store flyers.
- Combine errands: If you’re already stopping at a service station for a coffee or a quick shop, it may be worth paying the marginally higher petrol prices today for the convenience rather than driving extra miles to a cheaper station.
