A rental car can be one of the best ways to explore Greece, but fuel is becoming a much bigger part of the holiday budget. Here’s what travelers should expect to pay at the pump this winter.
Renting a car in Greece gives travelers something a bus timetable never will: the freedom to stop whenever the view is too good to ignore.
Fuel costs have climbed sharply in Greece, and travelers planning road trips in 2026 need to budget for much more than the rental itself.
The latest European Commission Weekly Oil Bulletin puts Greece’s average price for 95-octane petrol at around €2.20 per liter, while diesel is around €2.22 per liter. These are national averages including taxes, so individual petrol stations can charge more or less.
For a traveler driving a small rental car, that can add up surprisingly quickly.
What Does €2.20 a Liter Mean?
A typical small rental car might use somewhere around 6–7 liters of petrol per 100 kilometers, depending on the model, road conditions, driving style, and how much luggage is crammed into it.
Using 7 liters per 100 km as a straightforward example:
| 100 km | 7 liters | €15.40 |
| 250 km | 17.5 liters | €38.50 |
| 500 km | 35 liters | €77 |
| 750 km | 52.5 liters | €115.50 |
| 1,000 km | 70 liters | €154 |
The calculations use the current Greek average of approximately €2.20 per liter for 95-octane petrol.
And Greece isn’t a country where a traveler necessarily realizes how many kilometers they’ll accumulate.
A scenic detour here. A beach there. A mountain village that wasn’t on the original itinerary. One archaeological site that suddenly seems like a very good idea.
A Full Tank Can Cost More than €100
Take a rental car with a 50-liter tank.
At €2.20 per liter, filling it completely would cost about €110.
A 60-liter tank would be approximately €132.
Of course, most rental cars won’t arrive completely empty, and travelers don’t necessarily need to refill the entire tank. But it gives a much better idea of what the fuel bill can look like than simply looking at the price per liter.
For comparison, a 50-liter tank at €1.50 would have cost €75.
At today’s approximate Greek average, the same tank is around €110.
That’s a €35 difference every time you buy 50 liters.
Island Driving Can Cost More
The national average helps with planning, but travelers shouldn’t assume every Greek destination has the same pump price.
Transporting fuel to islands and remote areas adds costs, and prices can vary considerably between regions and individual stations. Greek fuel-price data has repeatedly shown regional differences, with island areas among the more expensive parts of the country.
That matters on a destination such as Crete, where a rental car can cover hundreds of kilometers during a single holiday.
It also matters on smaller islands, where travelers may have fewer stations to choose from.
So if the tank is getting low and there is a petrol station in front of you, filling up may be wiser than assuming the next one will be cheaper.
Crete Is Easy to Underestimate
Crete is a perfect example of how quickly driving distances can grow.
A traveler staying in Heraklion might decide to visit Chania, then stop somewhere along the coast, take a detour into the mountains, visit a beach, drive back through a different route, and make another stop for dinner.
Nothing about that itinerary sounds excessive.
The kilometers, however, add up.
At 7 liters per 100 km, 500 kilometers costs around €77 in petrol at today’s approximate national average.
A 1,000-kilometer holiday would mean roughly €154 in fuel.
And that is assuming a car actually achieves 7 liters per 100 km.
Mountain roads, air conditioning, traffic, frequent stops and enthusiastic driving can all push consumption higher.
Petrol or Diesel?
For tourists choosing a rental car, fuel type shouldn’t be the only consideration.
Diesel currently costs about €2.22 per liter, slightly more than 95-octane petrol at around €2.20.
The old assumption that diesel automatically means cheaper driving therefore doesn’t hold simply because the car uses diesel.
The actual calculation depends on the vehicle’s fuel consumption.
A diesel car that uses considerably less fuel per 100 kilometers can still cost less for a long journey, but travelers should look at the liters per 100 km figure rather than choosing based solely on the fuel label.
For a short holiday with relatively little driving, the difference may be negligible.
For a long road trip, it becomes more relevant.
Don’t Forget the Rental Company’s Fuel Policy
Before accepting the keys, check the rental agreement for its fuel policy.
A full-to-full arrangement generally means you receive the car with a full tank and return it full. That is easy to understand and lets you buy the fuel yourself at the station of your choice.
Other arrangements can work differently, including prepaid fuel or charges for returning the vehicle without the required fuel level.
Read the contract before driving away.
It is much easier to understand the fuel policy at the rental desk than at the airport, wondering why the final bill includes another charge.
Where Should Travelers Fill Up?
For a road trip, don’t build your entire fuel strategy around finding the cheapest station in Greece.
A difference of a few cents per liter matters, but running the tank dangerously low to save €2 or €3 is not much of a bargain when you’re halfway up a mountain.
The Greek government’s Fuel Price Observatory publishes fuel-price statistics and allows users to check prices by area.
The Region of Crete also publishes regular fuel-price bulletins, including weekly data for the Heraklion regional unit.
For travelers planning a particularly long drive, checking prices before setting out can help.
The Good News: Greece Is Still Made for Road Trips
Fuel prices may be painful, but they don’t change one of the best things about driving in Greece.
The road itself is often part of the experience.
A rental car lets travelers leave the main resort, stop at a village they weren’t planning to visit, pull over for a photograph, find a beach that isn’t in the guidebook, and discover that the road they chose has a spectacular view.
Just budget for the privilege.
In 2026, “we’ll just rent a car and see where the road takes us” needs a slightly larger fuel budget than it used to.
