It’s a Monday morning in mid-February. The coffee on the passenger seat is already lukewarm, the kids are late, and you roll into your usual gas station on autopilot. You grab the nozzle without thinking, glance at the price per liter, and feel that familiar pinch. Then your eyes catch something new on the pump: a large panel with strange lines, comparisons, and a big official-looking label about your cost “per 100 km”.
You pause for a second.
The guy at the pump next to you is staring at it too, frowning like he’s reading an exam question. The cashier inside is already repeating the same explanation for the third time this hour.
From February 12, a tiny change has slipped into your daily routine at the gas station. And it quietly changes the rules of the game.
From February 12, a new mandatory display at every pump
From February 12, gas stations have to display new mandatory information right where you pay and fill up. Next to the classic price per liter, you’ll now see clear information about the average cost per 100 km, sometimes compared with other fuels or even electric charging.
This isn’t a random idea from a bored civil servant. It comes from a European directive that aims to help drivers actually understand what they’re paying for each journey, not just at the moment of filling up.
On the pump or on a nearby panel, the message is the same: stop looking only at the flashing number on the screen, and start looking at what your car really costs to move.
Picture a suburban station on the edge of town. A family filling their diesel, a young delivery driver topping up with E10, a hybrid owner plugging into a fast charger.
Before February 12, each of them only really saw one thing: the price per liter or per kWh, and the final amount on the receipt. Today, they all see a comparative chart: how much their fuel costs for 100 km, compared with the neighboring pumps and sometimes with other energies.
The numbers don’t shout, but they speak clearly. Suddenly, your cheap liter doesn’t look so cheap when you realize your car devours 8 or 9 liters for every 100 km, while your neighbor’s smaller car quietly slips by at almost half that.
This new display responds to a very simple observation: most of us don’t naturally translate “€1.85 per liter” into “€13–€15 per 100 km”. We feel the pain at the pump, but we rarely calculate the real cost of our daily commute, our weekends away, our weekly school run.
Public authorities are pushing gas stations to make that mental calculation visible. It’s a nudge, not a lecture.
By forcing a unified, easy-to-read format, the goal is to give drivers a tool to compare fuels, stations and even vehicle types, without needing a calculator app or a spreadsheet. *The idea is that the information finally speaks the same language as your wallet.*
How to read the new panel and actually save money
When you stand in front of the pump now, don’t rush. Let your eyes travel beyond the big rotating digits. Look for a panel or sticker that mentions something like “average cost per 100 km” or “comparative cost by energy”.
You’ll often see a small table with different fuels: SP95-E10, SP98, diesel, maybe LPG or even electric charging. Next to each one, a cost estimated for 100 km, based on average consumption figures.
Use it like a quick snapshot. You know your own car roughly: if you drive a small city car, you can mentally adjust a bit down; if you have a heavy SUV, you nudge it up. The point isn’t perfection. The point is to understand the order of magnitude of your daily journeys.
Many drivers will be tempted to ignore this display, especially during the first weeks. The routine is strong: insert card, choose pump, squeeze handle, walk away cursing the price.
Yet those who take thirty seconds to look can spot big differences between nearby stations or fuels. For example, a driver noticed at a station outside Lyon that the liter of diesel was only 3 cents cheaper than in town… but the comparative panel showed a significantly higher cost per 100 km due to the typical type of vehicles and local average consumption they used in the estimate.
He realized his “good deal” wasn’t one. It’s a small detail, but multiplied by thousands of kilometers a year, it becomes real money.
Let’s be honest: nobody really does this every single day. We don’t want a maths class at 7:30 a.m. next to the windshield washer rack.
The trap would be to think this panel is yet another piece of bureaucratic decoration. In reality, it gives you three very practical levers: choose where you fill up, rethink how you drive, and slowly adjust what kind of car you want next. When you see “€11 per 100 km” vs “€7 per 100 km” side by side, your brain doesn’t forget it.
You might not change stations right away, but the next time you plan a long trip, that small voice will whisper: maybe take the route that passes by the cheaper station, or ease off the accelerator just a bit.
Turning this new rule into a daily advantage
The simplest method is to turn this new display into a personal benchmark. Each time you fill up, glance at the “cost per 100 km” and mentally link it to your usual routes.
For example, if your commute is 30 km round trip, that’s roughly a third of that 100 km figure. If the panel tells you €9 per 100 km, your commute is about €3 a day in fuel. Multiply by the number of workdays in a month, and suddenly you see the silent budget line that hides behind “going to work”.
Do this two or three times and you’ll start to build an instinctive sense of what each trip really costs. Without apps, without tables, just a small mental rule of three anchored in that panel.
Many people will feel a bit guilty when they realize the actual cost of their short but frequent trips: school run, quick drive to the bakery, gym 1.5 km away. That’s human. We’ve all been there, that moment when you understand your car is eating away at your budget quietly, kilometer after kilometer.
The goal is not to shame anyone. It’s to reclaim control. Start small: maybe group errands into a single trip once or twice a week, or car-share for a recurring journey. Even a modest change, seen through the “per 100 km” lens, turns into a visible gain.
You don’t have to transform your life. You just need one or two conscious choices, repeated.
“Before, I only stared at the price per liter and swore under my breath,” says Marc, 42, who drives 80 km a day for work. “Now that I’ve seen my cost per 100 km, I finally understood why my account was always tight at the end of the month. I changed my route to fill up at a station 5 cents cheaper and slowed down by 10 km/h on the highway. I saved around €40 last month, just like that.”

- Note the “cost per 100 km” at your usual station once.
- Compare it with another station on your usual routes within a week.
- Check your car’s real consumption on your dashboard over 200–300 km.
- Adjust your driving slightly (speed, acceleration) for one tank.
- Compare the next “per 100 km” reading in your own logbook: **you’ll see the difference**.
A small number on a panel that says a lot about our future
This new mandatory information at gas stations looks technical, almost cold. Yet behind those lines, there’s a very concrete question: how much are we ready to spend, every single day, just to move around?
Some will use it as a simple comparison tool between fuels. Others will see it as a sign pointing them toward a different car next time, or toward a different way of getting to work. A few will shrug and move on, until the next price spike forces them to look again.
The display doesn’t give orders. It opens a conversation with yourself. About your budget. About your habits. About the quiet power you actually have over what you spend on the road.
Maybe, a few months from now, we’ll look back and wonder how we ever managed without these numbers right in front of our eyes.

FAQ:
- Question 1What exactly changes at gas stations from February 12?
- Answer 1Stations must display standardized information showing the average cost per 100 km for the fuels they sell, sometimes with comparisons between fuels or with electricity. It complements the price per liter, it doesn’t replace it.
- Question 2Does this new panel change the price of fuel?
- Answer 2No, the rule is about transparency, not pricing. The price per liter remains set by the station, but you get extra information to understand what that price really means across your journeys.
- Question 3Are the “per 100 km” figures precise for my specific car?
- Answer 3They’re based on average consumption, so they won’t match your car perfectly. Use them as a reference point, then refine with your own consumption data from your onboard computer.
- Question 4Can I use this to compare fuel with electric charging?
- Answer 4Yes, when the panel includes electricity, you can see an estimate of how much 100 km costs with an EV versus a petrol or diesel car. **It’s a quick way to see if an electric switch might make sense for your usage.**
- Question 5What’s the most useful thing to do with this new information?
- Answer 5Start by comparing two or three stations you already pass by, then adapt your refueling habits and driving style slightly. Over time, use the “per 100 km” idea when thinking about your next car, so your choice matches your real-life budget.
