Oil makes petrol, diesel and jet fuel. It is also in plastics and packaging, and it runs the tractors and lorries that bring food to the shop.
Every price includes the cost of moving things. Lorries, ships and planes burn oil. When oil gets dearer, transport costs more, and shops pass part of it on.
A barrel holds 159 litres. At €80 a barrel, the oil in one litre costs about 50 cents. If oil doubles to €160, that part becomes about €1.
Oil doubles, so petrol doubles? No. The tax per litre stays the same. In a made-up €1.68 litre (€0.70 tax, €0.20 costs, 20% VAT), doubled oil makes it €2.29: about a third more.
EU countries must tax petrol at least €0.359 a litre, and most charge more, plus VAT of 17% to 27%. Compare the price per litre on this month’s fuel receipt with last year’s.
Oil moves fuel, plastics and every delivery. A fixed tax per litre means the pump moves less than the barrel.
