Fuel Prices Ireland – Week of 23 March 2026
National Overview
This week’s fuel prices Ireland snapshot shows the national average diesel at €2.11 per litre and the national average unleaded (petrol) at €1.92. The figures are based on data from 652 tracked service stations across the island, giving a solid picture of what drivers can expect when they pull up to the pump. While the headline numbers look familiar, the real story lies in the regional variations and the handful of stations that are offering truly bargain‑basement rates.
Where to Find the Cheapest Diesel
If you’re hunting for the cheapest diesel Ireland has to offer right now, the five stations listed below are the clear winners:
| Station | County | Diesel | Unleaded |
|---|---|---|---|
| Circle K Express Gweedore | Donegal | €1.46 | €1.59 |
| Kenny Fuels | Wexford | €1.60 | – (unleaded not listed) |
| Smith’s Service Station | Cavan | €1.64 | €1.64 |
| Applegreen Killarney | Kerry | €1.66 | €1.70 |
| Circle K Express Ballinrobe | Mayo | €1.66 | €1.70 |
These prices are dramatically lower than the national averages – in some cases more than 30 % cheaper. If you’re travelling through the north‑west, a quick detour to Gweedore could save you a bundle, and the same goes for a stop in Cavan if you’re heading east.
County Spotlights
Looking at the broader landscape, the cheapest counties for diesel (by average price) are:
- Co. Down – €1.80 (only one station monitored)
- Co. Cavan – €1.82 (6 stations)
- Co. Donegal – €1.85 (12 stations)
For unleaded, the top counties are:
- Co. Down – €1.61
- Co. Kilkenny – €1.88
- Co. Monaghan – €1.75
Even within the more expensive counties, there are still pockets of value. For example, Dublin’s average diesel price sits at €2.16, but you’ll still find stations below €2.10 if you check the FuelCompare app.
Practical Tips for Irish Drivers
- Plan your route with price in mind – Use FuelCompare.ie to map out the cheapest stations along your journey. A 10‑km detour can often shave off a few cents per litre, which adds up over time.
- Watch for “fuel‑only” deals – Some supermarkets and convenience stores run promotions where you can fill up for less if you also purchase groceries.
- Avoid peak times – Prices tend to creep higher on Monday mornings and Friday evenings when demand spikes. Try to fill up mid‑week if your schedule allows.
- Keep an eye on the exchange rate – The euro’s strength can affect crude oil prices, which eventually filter down to the pump. When the euro strengthens, you may notice a slight dip in petrol prices today.
- Stay loyal to a brand with a discount card – Brands like Circle K and Applegreen often run loyalty schemes that give you a few cent discount per litre.
