Where the €0.25 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.
44% of what you save by crossing into Slovenia is tax you are not paying, not cheaper fuel. Before duty and VAT the two markets are within €0.14 a litre of each other.
