The data used in this release mainly relate to the Revenue Commissioners monthly excise clearance volumes. The use of transport fuels such as Autodiesel and Unleaded Petrol are less seasonal than the use of home heating fuels. Price changes and exceptional weather can cause variations in the trends of excise clearances of home heating oils between years. Changes in the vehicle fleet fuel type composition can affect the mix in clearances of road fuels. See the Background Notes for the full definition of fuel excise clearances.
Autodiesel clearances decreased by 2.2% in the 12-month rolling period of September 2025 to August 2026 compared with September 2024 to August 2025.

Statistician's Comment
The Central Statistics Office (CSO) has today (03 November 2026) published Fuel Excise Clearances August 2026. Clearances are the duty paid on the quantity of oil removed from bonded warehouses and provide a proxy for sales (See Editor’s Note below).
Commenting on the release, Dr. Robert Stapleton, Statistician in the Climate and Energy Division, said: "Autodiesel clearances were 2% lower in the 12-month rolling period of September 2025 to August 2026 compared with September 2024 to August 2025. This is equivalent to a decrease of 74 million litres in Autodiesel clearances in the last 12 months.
Unleaded Petrol clearances have increased by 6% in the first eight months of 2026 compared with the same period in 2025. Comparing the year to August 2026 with previous years, this is the sixth year in a row that has seen year-on-year increases in Unleaded Petrol clearances.
Kerosene clearances were 6% lower in the first eight months of 2026 compared with the same period in 2025. This equates to a decrease of 30 million litres in Kerosene clearances over this period.
Marked Gas Oil clearances decreased by 1% in the 12-month rolling period of September 2025 to August 2026 compared with September 2024 to August 2025, a reduction of six million litres in Marked Gas Oil clearances."
