The results of the March AA Ireland fuel price survey show mixed results for motorists. The headline numbers reflect the pressure at the pump where diesel and petrol prices have risen considerably compared to February. But the news gets a little brighter for EV owners as the AA reports an unchanged situation with home-charging rates and pay-as-you-go rates remaining static.
Diesel and petrol prices climb
The national average pump price for diesel surged to approximately €1.90 per litre, an increase from €1.72 in the previous month. Petrol rose to approximately €1.81 per litre, which is an eight-cent increase from February’s €1.73. These prices are shown in the AA’s “Irish fuel prices: March 2026” table. For comparison, the pre-tax price of diesel is approximately 83c per litre and that of petrol is approximately 66c per litre; the remainder is made up of excise duty, carbon tax, the NORA levy and VAT.
The dramatic rise in diesel prices stands out. Some of this stems from the tax mix, with diesel subject to slightly less excise duty than petrol, but the price of refined diesel has surged in recent weeks. The Irish Road Haulage Association warned that diesel has exceeded €2 per litre, while fuel card companies have advised clients to expect increases of over 12 cent per litre.
‘Motorists are seeing a significant increase in fuel prices this month, particularly for diesel, which has jumped considerably since February. While petrol prices have also risen, diesel drivers will feel the biggest impact at the pumps. EV charging costs, however, remain stable, continuing to provide predictable running costs for electric vehicle owners.’

Why are costs climbing
AA Ireland highlights that pump prices are still heavily influenced by movements in global oil markets, geopolitical events, including the recent escalation in the Middle East, and currency exchange rates. Therefore, prices can change quickly and vary significantly depending on location and fuel retailer.
Members have indicated that pump prices have been fluctuating above and below €2.00 per litre from day to day, making it all the more important to shop around where feasible. A difference of even a few cents per litre can add up significantly over time.
Reducing Your Fuel Costs
Drivers can help reduce fuel consumption and running costs by adopting more efficient driving habits:
- Drive smoothly and avoid harsh acceleration or braking
- Maintain a steady speed where possible, especially on motorways
- Remove unnecessary weight from the vehicle
- Avoid excessive idling by turning off the engine when stationary.
- Plan journeys in advance to reduce unnecessary mileage
Vehicle Maintenance & Fuel Efficiency
AA Ireland is also reminding motorists that regular vehicle maintenance not only improves safety but can also help reduce fuel consumption.
Simple checks that make a difference:
Maintaining correct tyre pressure and ensuring the vehicle runs smoothly can significantly affect fuel consumption in the long run. Regular maintenance also helps to avoid unforeseen breakdowns, which are often due to battery problems, tyre issues, and general deterioration.
- Tyre Pressure
- Engine Servicing
- Air Filter
- Battery Check
March’s report shows a steep rise in the cost of diesel fuel and a smaller increase in the cost of petrol, but there has been no change in the cost of charging electric vehicles. AA Ireland is advising drivers to drive efficiently, keep their cars in good shape, and, where possible, shop around for the best fuel prices to help manage rising motoring costs.
