Why motorway fuel costs more

Motorway service areas pay high rents and run around the clock, and they have little nearby competition: once you are on the motorway the next option may be 30 miles away. Prices reflect that.

Why supermarkets are often cheaper

Supermarkets use fuel to bring shoppers onto the site and buy in very large volumes. Not every supermarket forecourt is the cheapest in town, though, so it is still worth checking the map.

"Supermarket" uses the flag that retailers set in the Fuel Finder data, which isn't always accurate.
