Data Methodology
Where our numbers come from, how often they change, and what they cannot tell you.
This page explains where our numbers come from, how often they change, and what their limitations are. We publish it because a price figure without a stated source and date is not worth much.
Global country prices
We track retail Gasoline 95 (or the closest nationally standard grade) in 169 countries, expressed in U.S. dollars per liter. Two sources feed the data:
- European Union (27 countries): the European Commission’s Weekly Oil Bulletin (prices with taxes, gasoline and diesel), converted from euros at the European Central Bank reference rate of the day. These figures update automatically every week, and the weekly change we show is the real difference from the previous bulletin.
- All other countries (142): GlobalPetrolPrices.com, which aggregates national reporting from energy ministries, fuel regulators and major retail chains. These are refreshed periodically from its published snapshots; each country page states the exact date of the figure shown. Because this source is not weekly, we do not show a weekly change for these countries.
The date stamp above the world price table shows the date of the latest EU bulletin and of the latest snapshot for the remaining countries.
United States prices
U.S. regional prices come directly from the U.S. Energy Information Administration (EIA) via its public API. The EIA surveys retail outlets and publishes updated regular-grade gasoline prices once per week, normally on Mondays. Because the source is weekly, the figures on our U.S. section change weekly rather than daily, and each is labeled with the week it represents.
Unit and currency conversion
Gallon figures are derived from liter figures using the U.S. liquid gallon (1 gallon = 3.78541 liters). If you are comparing against a country that uses the imperial gallon, the two differ by roughly 20 percent. Currency conversions use reference exchange rates and are intended for comparison, not for transactions.
Price outlooks
Short-term outlooks (about four weeks) start from the U.S. Energy Information Administration’s Short-Term Energy Outlook crude oil forecast (Brent for most markets, WTI for North America). We estimate the share of each country’s pump price that is crude cost, apply a partial pass-through, and factor in the recent trend of the local currency against the dollar using European Central Bank rates. Markets with government-set prices are shown as regulated instead of forecast. They describe a direction and a plausible range, not a guaranteed outcome. Fuel markets respond to refinery outages, currency swings, tax changes, and geopolitical events that no model predicts reliably. Treat every projection on this site as context, not as a forecast to act on.
Known limitations
- National averages hide local variation. Prices differ between a city center and a rural highway, and between competing stations on the same street. Our figures are national reference points.
- Subsidized markets move in steps. In countries where fuel is heavily subsidized or price-controlled, the retail price can sit unchanged for months and then move sharply when policy changes.
- Exchange rates add noise. A country's price in U.S. dollars can shift without any change to the local pump price, purely because its currency moved.
- Reporting lags differ by country. Some national agencies publish weekly, others monthly.
Corrections
We correct errors when they are pointed out. If a figure looks wrong for a country you know, write to contact@fuelpredict.com and tell us what it should be; we will check it against the source and update if warranted.
