That's according to the latest data publication by Central Statistics Office (CSO).

Excise clearances of marked gas oil in June 2025, at 102 million litres, were down 3% compared with the June 2024 figure of 105 million litres. Green diesel is primarily used for off-road purposes such as agriculture and the heating of larger buildings.

Excise clearances of unleaded petrol in June 2025, at 92 million litres, were 5% higher than the June 2024 figure of 88 million litres.

This was the highest volume of unleaded petrol clearances recorded for the month of June since 2018.

"Wholesale prices of autodiesel and unleaded petrol in June 2025 were lower than June 2024."
