Iran’s oldest oil refinery in the southwestern city of Abadan would account for 4 million liters.

Arak refinery in central Iran will be producing 16 ml of euro-4 gasoline after its overhaul.

Euro-4 gasoline distribution lies within the framework of a government directive with a view to curbing air pollution.

Euro-4 gasoil and gasoline distribution started in major cities of Tehran, Arak and Karaj last calendar year. Tabriz refinery started distributing 1ml/d of euro-4 gasoline in the northwestern city of Tabriz last summer.
