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

Retail gasoline prices for the 169 countries we track are compiled from GlobalPetrolPrices.com, which aggregates national reporting from government energy ministries, state fuel regulators, and major retail chains. Figures represent the typical retail price of Gasoline 95 (or the closest nationally standard grade) in U.S. dollars per liter, converted at prevailing exchange rates.

These figures are reviewed and refreshed on a weekly cycle. The date stamp shown above the world price table always reflects the release we are currently publishing.

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 are statistical projections built from recent price movement and crude oil benchmarks. 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

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.
