Is there a discrepancy between the indicated price at a petrol station and the price you have to pay at the pump? In that case, you have the right to pay the lower price, unless it is clearly a mistake (for example, if the indicated price is extremely low compared to the normal price).

Moreover, the law prohibits charging prices higher than the maximum allowed. The maximum prices for domestic heating oil and vehicle fuel are set and published on the FPS Economy website.
