FuelWatch shows live diesel prices at stations near your location anywhere in Ireland, updated in real time by drivers as they fill up. Open the map, allow location access, and compare what every nearby forecourt is charging before you pull in.
Open app.fuelwatch.ie or the free iOS app and allow location access. The map centres on your position and shows the diesel price at each station around you, with recently updated stations flagged as fresh.
Diesel rewards the check more than petrol does, because diesel drivers tend to cover more kilometres and fill larger tanks. A 70-litre van tank at 8 cents per litre cheaper is over five euro saved on a single fill, and for anyone filling weekly that compounds quickly.
Motorway service areas and stations on busy national routes often price above town forecourts a few minutes off the road. The map makes that difference visible before you commit.
Diesel carries a lower excise rate than petrol but a higher carbon charge, so the total tax load on the two fuels is close but not identical. VAT at 23 percent applies to both, charged on the price after duty.
The wholesale side diverges more. Diesel demand is driven by freight, agriculture, and commercial fleets rather than by private motoring, so it responds to different pressures — harvest season, haulage volumes, and heating demand in colder months, since diesel and heating oil come from the same middle-distillate part of the barrel.
That is why diesel is sometimes dearer than petrol and sometimes cheaper, and why the gap between the two moves through the year.
FuelWatch tracks road diesel on the Car Fuel layer, and covers green diesel (agricultural and marine diesel) and home heating oil as separate layers with their own prices and depots. If you run farm machinery or heat with kerosene, those layers are where to look rather than the forecourt map.
Browse diesel prices by county from the fuel prices by county pages, or see how today compares with recent months on the national price chart.

Diesel carries a lower excise rate but a higher carbon charge than petrol, so their tax loads are close. The difference you see at the pump comes mostly from wholesale conditions: diesel demand is driven by freight, agriculture, and heating rather than private motoring, so the two fuels move apart at different times of year.
Yes. Green diesel (agricultural and marine diesel) and home heating oil are separate map layers with their own prices and depots, alongside the road diesel shown on the Car Fuel layer.
