It happens on a Tuesday night, when the low-fuel light comes on at the worst possible moment. Rain, a long day, kids in the back. You pull into the nearest gas station almost on autopilot, glance briefly at the price per liter, and start filling up. Ten minutes later, you drive off with the uncomfortable feeling that you’ve just spent too much, again, without really knowing why.
At the pump, everything goes fast and stays blurry.
From March 12, that blur is going to shrink in a very concrete way.
From March 12, a new line on the pump that can change the bill
Starting March 12, motorists will discover a new mandatory piece of information right on the pump. Right next to the usual price-per-liter display, stations will have to show the estimated cost of 100 km with the fuel you’re buying. Simple, direct, almost brutal.
Instead of just seeing “1.89 €/L”, you’ll see how much a typical car spends to travel 100 km with that fuel. Suddenly, the numbers speak your language: distance, wallet, daily life. No more mental gymnastics. Just a concrete, comparable figure.
Picture a busy suburban station on the first day of the change. Two lanes, same brand, but two different fuels: standard E10 and a supposedly “premium” version, much more expensive per liter. On the new display, though, the story shifts. On one pump, 100 km is estimated at 10.30 €. On the other, 100 km climbs to 12.40 €.
The price difference per liter doesn’t seem huge at first glance. But stretched over 100 km, then over a month of commuting, it becomes a real number with a real sting. The kind that makes you quietly move the car to the next pump.
This 100 km cost display is inspired by what already exists for household appliances and cars themselves. Lawmakers know that price-per-liter is abstract, while cost-per-distance connects instantly with the way we live and drive.
This new rule also forces brands to be more transparent about their positioning. Some premium fuels will suddenly look less magical. Others might justify their price by a lower consumption over distance. In both cases, the consumer finally gets a usable yardstick, not a puzzle.
How to read this new info so you actually save money
The key reflex will be simple: stop staring only at the big price-per-liter number, and let your eyes slide down to the “€/100 km” line. That’s your new benchmark, your reference price.

If you hesitate between two fuels, compare the cost per 100 km, not the price per liter. The lower number wins, especially if you mostly drive the same type of route every week. Over a month, the difference of 0.80 € or 1 € per 100 km can easily turn into 15, 20, even 30 € saved.
Plenty of drivers will still pick a fuel “by habit” or because they’ve “always taken the blue one, not the green one”. That’s human. The emotional weight of routine is strong, especially when you’re in a rush and just want to get home.
Let’s be honest: nobody really calculates consumption on a spreadsheet after every fill-up. This new display is a shortcut for all of us who never had the time or the patience to be fuel economists. Take ten seconds, one glance, one quick comparison. Those ten seconds can quietly protect your bank account all year.
From a transport economist I talked to last year: “When you translate a technical price into a daily-life cost, people change behavior much faster. We know that with electricity, we’re about to see it with fuel.”
- Compare the “€/100 km” of at least two fuels when available.
- Note on your phone which option usually comes out cheaper for your type of car.
- Stick to that choice for a month and watch how often you refuel.
- Re-check the display when prices fluctuate sharply.
- Use the figure as a talking point at home to adjust your monthly budget.
A small number on the screen, a big change in how we drive
This new rule won’t magically lower fuel prices, and nobody at the pump will suddenly hand you a discount. What it does is shift a little bit of power back towards drivers, in a very quiet, very practical way. With clearer information, you can choose fuel like you choose a phone plan: based on what it really costs you over distance, not based on marketing names.
Some will ignore it, others will take a picture for social media, some will have a debate in the car between diesel, E10, or E85. But once you’ve seen, in black and white, how much your 100 km truly costs, it’s hard to unsee it. *The next time your warning light comes on, this small extra line on the pump might be the nudge that finally helps you drive, and spend, a little differently.*

FAQ:
- Question 1What exactly changes on March 12 at gas stations?Stations will have to display an estimate of the cost of driving 100 km with each type of fuel sold, alongside the traditional price-per-liter indication.
- Question 2Will this new information lower fuel prices?No, prices themselves don’t change because of the rule. The benefit comes from clearer information, which helps drivers choose the most economical option among the fuels available.
- Question 3Is the €/100 km figure personalized to my car?No, it’s based on standardized consumption assumptions, like energy labels. It’s not tailored to your exact vehicle, but it gives a solid, comparable benchmark.
- Question 4Can premium fuels still be interesting with this new display?They might, depending on your engine and driving style. If a more expensive fuel really reduces consumption enough, its €/100 km value can come close to or beat standard fuels. The display will help you see that gap clearly.
- Question 5How can I use this info to save money all year?Compare the €/100 km across fuels at your usual stations, pick the one that consistently comes out lower, and stick with it for your regular routes. Combine that with smoother driving and regular tire checks, and you can cut your yearly fuel budget without drastic lifestyle changes.
