Per ethanol grade
E5 gasoline grade (conventional gasoline containing up to 5% v/v of ethanol) was the main gasoline grade in Ireland until E10 (conventional gasoline containing up to 10% v/v of ethanol) was introduced in the market from April 1, 2023. In addition, the Irish Legislation requires a minimum of 5.5% v/v of ethanol in gasoline from July 1, 2023. This means that E10 is the main gasoline grade in the country.
