Some selected filling stations on motorways are exempt from this measure, the oil company added.

Television channel RTL found one Shell filling station where the petrol supply ran out.

According to an expert of filling station monitoring website Holtankoljak, Shell stations receive fuel on a monthly basis, so if it runs out, they will not receive any more that month.

MOL said it is delivering 15-20% more fuel to its partners than in normal periods, and is also buying fuel from abroad.
