Save Gas Prices Workflow

Key takeaways

The Save Gas Prices Workflow: preparation and basics

Before you take action, you need a solid baseline. Many people jump straight to saving tips without knowing where they stand. The result: potential is missed or wrongly prioritised.

Analyse consumption and driving behaviour

Track your actual fuel consumption for two to four weeks. Use the trip computer (Bordcomputer) or a simple spreadsheet: litres tanked, kilometres driven, calculated litres per 100 km. You will quickly see whether your vehicle is in the normal range or whether technical problems are already increasing consumption.

Also look at your driving style. Are you mostly doing short trips under five kilometres? Cold-start consumption is then particularly high. A lot of motorway driving, on the other hand, supports efficient consumption — provided you keep your speed moderate.

Check the technical basics

Run through these checks before starting the workflow:

• Tyre pressure: Low pressure raises rolling resistance and fuel use. Check monthly when tyres are cold.
• Service condition: A worn air filter, old spark plugs or stale engine oil noticeably increase fuel costs.
• Roof racks and luggage: Roof boxes and bike racks you don't need create drag and should come off.
• A/C and electrics: Check which consumers run continuously.

Know your contract data

Do you know your current gas provider? Your Arbeitspreis (unit price per kWh) and the monthly Grundpreis (base fee)? You'll find these on your last annual statement (Jahresabrechnung). Without them, a meaningful comparison is impossible.

With these numbers in hand, you're ready for the next steps of the workflow.

Efficient driving in everyday life

The good news first: you don't need a new car to consume less right away. Anticipatory driving cuts fuel consumption by up to 20 percent according to ADAC, the German motoring association. This is not a theoretical figure but a proven, real-world result. (External German-language source.)

Look ahead and shift up early

If you look far enough ahead, you brake less often and accelerate more gently. That's the core principle of efficient fuel consumption. Concretely: if you see a red light, take your foot off the accelerator and coast, rather than rushing to the light and braking hard. Every unnecessary brake destroys kinetic energy that fuel paid for.

Shifting up early is equally effective. Most modern cars show the optimal gear in the cockpit. Rule of thumb: change up at about 2,000 RPM. Engines run more efficiently at lower revs.

Avoid idling and use Start-Stop

An engine running at standstill burns fuel without moving the car. Sixty seconds of idling equals the fuel needed for several hundred metres of driving. Use your car's Start-Stop system consistently. If your car doesn't have one, switch the engine off manually for waits over 30 seconds.

Reduce A/C and other consumers

The air conditioning adds up to 1.5 litres per 100 km. It sounds small, but at 15,000 km a year it adds up to roughly 225 extra litres of fuel. Turn the A/C off in moderate weather and open a window instead. Above about 130 km/h on the motorway, A/C is aerodynamically better than open windows; below that, it's the opposite.

Other consumers that raise fuel use: seat heaters, rear-window defrosters, ventilation fans at maximum, and daytime running lights left on. Turn them on and off as needed instead of running them all the time.

Reduce weight and improve aerodynamics

Every 100 kg of extra load adds about 0.3 litres per 100 km. Many people underestimate the impact of roof racks, bike carriers and heavy luggage in the boot. A permanently mounted roof rack measurably increases drag even when empty.

Clear unnecessary items out of your car regularly. Tool boxes, prams or sports gear used only occasionally shouldn't live in the vehicle permanently.

Pick the right time to fill up

Since April 2026 the so-called 12-Uhr-Regel (noon rule) applies in Germany: petrol stations can only raise prices once a day, at 12:00. The optimal time to refuel is therefore before noon. E10 typically rises by around 9 cents at midday, diesel by about 10.5 cents. Filling up in the morning can already save several euros on a 50-litre tank.

Also use apps like the ADAC fuel price app or Tankerkönig to find the cheapest station nearby. Price differences between stations in the same city can reach 15 cents per litre.

Energy-saving tyres as a long-term investment

Low-rolling-resistance tyres (recognisable by the EU tyre label class A or B for fuel efficiency) measurably lower consumption. The difference between a class C and a class A tyre averages 0.1 to 0.2 litres per 100 km. At 15,000 km a year that's up to 30 litres of fuel saved. At your next tyre change, check the energy label.

One more thing: E10 costs about 5 to 6 cents per litre less than E5. Almost all petrol cars built from 2010 onwards are approved for E10. Check your vehicle documentation or the official ADAC database. Consistently using E10 saves roughly €2.00 to €2.40 per fill-up on a 40-litre tank.

Optimise gas contract and switch tariff

Focusing on driving alone leaves one of the biggest savings levers unused. Switching gas providers can save a typical household with 20,000 kWh annual usage up to €800 per year. Even so, according to the Federal Network Agency (Bundesnetzagentur) around 16 percent of all households stay in the more expensive default supply (Grundversorgung).

Step by step to a cheaper tariff

1. Identify annual usage: Pull your last annual statement and note the kWh, current unit price (Arbeitspreis) and base fee (Grundpreis).
2. Use a comparison portal: Enter usage, postcode and current terms into a portal. meinetarife24 offers a quick free input form.
3. Check direct offers: Provider websites can be cheaper than portals, since portals include commission. After the comparison, also check the providers directly.
4. Calculate the total: Don't compare unit price alone. Calculate (unit price × annual kWh) + (base fee × 12). A low unit price with a high base fee can be worse than a balanced tariff.
5. Check price guarantee and term: Tariffs with a price guarantee protect against increases during the contract term. Note the minimum term: 24-month contracts lock you in but often have better rates.
6. Submit cancellation: Cancel the old contract within the notice period. In the default gas supply the period is usually just two weeks.
7. Confirm switch and claim bonus: Many providers grant new-customer bonuses of €50 to €150. Note the switch date and check after three months whether the bonus was credited.

Default supply versus special tariffs

The Grundversorgung is a safety net, not a permanent tariff. Anyone staying in it for more than three months pays a clear premium. Switching to a cheaper gas provider is worthwhile in nearly every case.

Understanding the price components

The unit price (Arbeitspreis, in cents per kWh) is the variable part of your gas bill and depends directly on consumption. The base fee (Grundpreis) is a fixed monthly charge regardless of usage. For a household with 20,000 kWh annual usage and a base fee of €10 a month, fixed costs total €120 a year — that's 0.6 cents per kWh on top. If you only compare unit prices, you miss this cost block.

Monitor and steer consumption continuously

A one-off switch or a short-term change in behaviour is not enough. Long-term success at lowering gas prices needs fixed control routines.

Tools and apps for daily use

• Trip computer: Watch the consumption readout actively while driving. Many drivers never look at it, although it gives direct feedback on driving style. An instantaneous reading above 10 litres per 100 km in city traffic is a clear signal to adjust.
• Fuel-tracking apps: Apps like Spritmonitor or Fuelly let you log every fill-up. After a few weeks, clear trends emerge: which routes consume most? Did the new driving style change anything?
• Gas usage apps: Many gas providers offer their own apps to view monthly consumption. Portals like meinetarife24 complement this with regular gas tariff comparisons.
• Smart thermostats: For domestic gas use, a programmable or smart thermostat pays off. According to Stiftung Warentest, immediate measures like shock ventilation and lowering room temperatures noticeably reduce gas consumption at home.

The annual statement as a control tool

Many consumers file the annual statement away unread. That's a mistake. It tells you whether your monthly advance payment is too high or too low, whether your usage shifted year-over-year, and whether the current tariff is still competitive.

Every year, when you get the statement, check three things: usage versus last year, current unit price versus market offers, and remaining contract term. These three points form the basis of your yearly optimisation check.

Establish fixed routines

Sustainable saving is built on habit, not one-off actions. Plan the following routines firmly:

• Monthly: Check tyre pressure, log fuel use, review the consumption readout.
• Half-yearly: Vehicle service per manufacturer's schedule, check air filter and oil.
• Yearly: Compare gas contracts, review the annual statement, verify bonuses, reflect on driving habits.

These routines together take less than two hours a year but can save you several hundred euros.

A personal take from our editorial team

Over the past few years we've worked with many people who wanted to cut their energy costs. What surprises us repeatedly: most focus either only on driving style or only on tariff switching. Those who do both consistently save substantially more.

The 12-Uhr-Regel has changed how we fill up — we now refuel almost exclusively before 11 AM. The ADAC criticises this rule — and rightly so, since oil companies bake risk premiums into prices. Still, those who know and use the rule pay less than those who ignore it.

Our lesson: the small levers are chronically underestimated. Less weight in the car, no roof rack in winter, shifting up earlier — each one alone seems trivial. Together they make a visible difference on your bank statement.

Our personal tip for sustainable saving: treat the provider switch as a yearly chore, not a one-off action. Done consistently, you never pay more than necessary.
