How to read this
Border decisions turn on your own detour: the saving on a tank has to beat the fuel burned getting there. If you are weighing up the drive, each country page has a detour checker that sets the saving against the fuel the trip itself burns, using that country's own price. Drivers near the border should also check the live station pages on the cheaper side, where station prices can differ from the national average in either direction.
