| LPG | €1.02 | €1.09 | €0.07 · €3.60/tank |
Where the €0.34 gap comes from
Petrol is the same product on both sides of this border, refined from the same crude. Stripping duty and VAT out of both pump prices shows how much of the difference is fuel — and how much is politics.
The fuel itself is more expensive before tax in Spain. It is cheaper at the pump anyway, purely because Spain taxes it less than France does.
