Fuel prices have fallen to their lowest levels since September 2021, the latest AA fuel prices survey shows.
The average petrol price fell to €1.59 in April, which marked a fall of 3.6% on March.
The price of diesel has also dropped significantly, with the average at €1.51, down 9% on last month.
But the AA said these prices are unlikely to last as a phased restoration of previously reduced rates of excise on petrol and diesel will take place in three stages over the coming months.
This reintroduction of duty will see rates restored by six cents per litre of petrol and five cents per litre of diesel from June 1.
On September 1, these rates will then increase by seven cents for petrol and five cents for diesel.
The Government will fully restore the rates on October 31 with a final increase of eight cents for petrol and six cents for diesel.
"We have not seen prices this low for petrol and diesel since September 2021, well before the start of the ongoing conflict in Ukraine, which led to a dramatic increase in fuel prices internationally," said AA Ireland's Head of Communications Paddy Comyn.
"Motorists won't be able to enjoy these prices for too long, however. We already know that unless prices fall again, then petrol will be back up to around €1.80 per litre and diesel to €1.76 per litre by the end of October - which were the same as at the start of the Ukraine conflict," he added.
Meanwhile, EV drivers are paying almost identical amounts this month as electricity prices remain elevated.
The average EV driver is paying €1,131.04 to charge their car over the course of the year, down from €1,138.13 in the previous month.
However, those that are taking advantage of Smart Meters and cheap night rates are paying as little as €421.43 to cover the same 17,000km distance. Those that are charging exclusively on public chargers could be paying up to €2,150.27 a year.
AA calculates a diesel car will travel, on average, around 850km on a tank compared to 700km on petrol, which is why even though diesel is more expensive, the consumer is still likely to use less of it for the same average 17,000km a year.
