Smart fuel assistant

Ask about prices, stations and the best time to fill up. Every answer is grounded in official pump price data.

How the answer is built

The assistant identifies the request, checks stations in the area and reuses deterministic ranking or forecasting calculations. The language model explains those results; it does not invent a price or station.

Useful questions to ask

  • Where is the lowest total fill-up cost?
  • Should I wait until tomorrow or fill up now?
  • Which station is worth the detour for 45 litres?

Data, limits and confidence

The answer shows price freshness and relies on available public registers. A forecast remains probabilistic. When data is insufficient, Karburo says so instead of filling the gap with a made-up value.

Why price per litre is not enough

The ranking combines the amount you need, vehicle consumption and fuel used on the detour. A cheaper but distant station can therefore cost more overall.

Origin and update frequency

Depending on the country, prices come from a public register, official service or attributed partner. Karburo keeps the supplied date, flags old data and briefly retains the last usable cache during an outage.

Countries and data actually covered

Karburo can compare station prices or a reference schedule in France, Spain, Italy, Portugal, Morocco, Austria, Germany, connected Australian regions and China. A local page stays out of the index when dated observations are insufficient; EV coverage is assessed separately.

Fuel and charging

Diesel, SP95, SP98, E10, E85 and LPG where national registers publish them, plus known EV chargers.

No account required

The question is processed to produce the answer. Vehicle details and preferences stay on the device; no public personal history is created.

Frequently asked questions

Where is the cheapest fuel?

Karburo ranks stations around you by real cost, detour included.

Should I wait before filling up?

The forecast estimates the trend over 24 hours to 7 days and shows its confidence level.
