Check at the pump

These prices come from the stations themselves, which must report every change to Fuel Finder within 30 minutes. The date next to each price is when it last changed; one that has not moved for over a month is flagged, as the station may have stopped reporting. Always confirm on the forecourt totem before filling up.
