Fuel prices across Greece continue to highlight a widening regional gap, as new data from April 23, 2026 show motorists facing significantly different costs depending on where they refuel. The national average price of unleaded petrol has climbed to €2.021 per liter, firmly establishing levels above the €2 threshold.
Diesel for transportation remains a key concern for professionals, averaging €1.894 per liter, adding further pressure on transport-dependent sectors.
Islands Face the Highest Costs
The price landscape is sharply split between mainland Greece and the islands, where transportation and supply costs drive prices considerably higher.
The most expensive region is the Cyclades island group, where unleaded petrol reaches €2.185 per liter, while diesel climbs to €2.140—higher than petrol prices in the capital. The Dodecanese islands follow at €2.116, with Kefalonia also recording elevated levels at €2.088.
These figures underline the structural challenges of fuel distribution to remote and island regions, where limited supply routes and logistics costs significantly affect retail prices.
Mainland Offers Relative Relief
In contrast, several mainland areas manage to keep prices closer to or slightly below the €2 mark, offering limited relief for consumers.
The region of Pieria records the lowest average price nationwide at €1.996 per liter, making it the only area in Greece still clearly below €2. Athens remains just at the threshold with €2.000, followed closely by Imathia at €2.001 and Kozani at €2.003.
While the differences may appear small, they reflect a consistent pattern of regional disparity that has become increasingly visible in everyday fuel costs.
A Divided Fuel Market
The data highlight a two-speed fuel market in Greece, where geography plays a decisive role in pricing. Island regions consistently bear the highest burden, while mainland areas—especially in northern Greece—retain relatively lower prices.
