Petrol and diesel prices saw small decreases again this month - the fourth month in a row of cheaper prices - the latest AA Ireland monthly Fuel Price Survey shows.
The AA noted the last time that both prices had slowed by four months in a row was in 2017.
Petrol is down from €1.72 a litre in December to €1.68. Diesel also fell by four cent a litre, from €1.72 to €1.68.
But the AA said that prices remain elevated above 2023 lows of €1.57 for petrol and €1.47 for diesel.
Blake Boland, Head of Communications for the AA Ireland, said crude oil prices have risen slightly since December, but are far below peaks of last year.
"Thankfully crude oil prices have reduced since we saw highs of $94 per barrel in late September. It is now hovering around $79 per barrel. Although not directly linked, it is great to see this fall in crude oil prices transferring to the pumps in Ireland over recent months," he added.
But he added that this does not necessarily mean that prices in forecourts will continue to fall.
"We have seen a lot of producers stepping up supply of oil based on high prices seen in September. That incentive is not there as strongly anymore. A combination of factors lead to the price we pay at the pumps, and further escalation of conflict in Ukraine or the Middle East could swing market prices," he added.
Meanwhile, electric vehicle owners are seeing a marginal drop in charging costs in January according to the AA Ireland Fuel Price Survey.
EV owners will pay on average €967 per year, compared to the December average of €975 to cover the national average of 17,000km per year.
The figure of €967 is far higher compared to before Russia's invasion of Ukraine, but still compares quite favourably with combustion engine equivalents.
A similarly sized diesel vehicle will cost about €1,999 to cover that same distance of 17,000km.
