Fuel Prices Ireland – Week of 3 April 2026

If you’ve been keeping an eye on the pump lately, you’ll notice that fuel prices Ireland are humming along at a new high. For the week beginning 3 April 2026 the national average sits at €2.10 per litre for diesel and €1.89 per litre for unleaded petrol. Those figures come from a network of 640 stations tracked across the island, so you can be confident they represent the real picture on the road today.

National Snapshot

Diesel: €2.10 / l (average)
Unleaded (petrol): €1.89 / l (average)

Compared with the same period last year, diesel is up roughly 6 pence and unleaded is up about 4 pence. The rise is being driven by higher wholesale costs and a modest dip in the euro’s value against the dollar. While the numbers look steep, there are still pockets of relief – especially for those hunting the cheapest diesel Ireland has to offer.

The Cheapest 5 Stations Right Now

If you’re planning a fill‑up this week, these five outlets are beating the national average by a wide margin:

Station	County	Diesel	Unleaded
Asda Petrol	Co. Fermanagh	€1.60	€1.50
Circle K Express Burt	Co. Donegal	€1.64	€1.80
Applegreen Pettigo Filling Station	Co. Donegal	€1.66	€1.78
Top Oil Carlow Depot	Co. Carlow	€1.66	€1.72
Circle K Express Ballinrobe	Co. Mayo	€1.66	€1.70

These stations are the cheapest diesel Ireland can currently offer, and they also sit at the lower end for petrol. If you’re driving a diesel‑run vehicle, a quick detour to Fermanagh or Donegal could save you a few euro per tank.

County‑By‑County Average Prices

Below is a quick glance at how counties stack up. The list starts with the lowest‑priced areas and works its way up to the most expensive:

Co. Fermanagh – Diesel €1.60, Unleaded €1.50 (1 station)
Co. Armagh – Diesel €1.70, Unleaded €1.55 (1 station)
Co. Tipperary – Diesel €1.94, Unleaded €1.83 (7 stations)
Co. Donegal – Diesel €1.97, Unleaded €1.88 (13 stations)
Co. Carlow – Diesel €2.00, Unleaded €1.87 (8 stations)
Co. Roscommon – Diesel €2.01, Unleaded €1.84 (5 stations)
Co. Mayo – Diesel €2.02, Unleaded €1.81 (16 stations)
…
Co. Dublin – Diesel €2.13, Unleaded €1.90 (146 stations)

As you can see, the border counties still hold the best deals, while the capital region hovers just above the national average. For drivers who regularly travel between counties, it can be worth planning your route around the cheaper zones, especially for longer trips.

Practical Advice for Irish Drivers

Plan Ahead – Use the weekly average data to decide whether a small detour to a neighbouring county will be worth the savings. Even a €0.20 drop per litre adds up over a 50‑litre fill.
Combine Errands – If you have a few stops on the same day, try to hit the cheapest station first, then fill up again later if prices dip further.
Watch the Time – Pump prices often shift after 5 pm as stations adjust to the evening rush. Checking petrol prices today in the late afternoon can reveal a surprise discount.
Keep an Eye on Promotions – Some retailers run limited‑time offers (e.g., “buy one litre, get 10 c off the next”). Sign up for their newsletters or loyalty cards.
