What goes into the price at the pump
- Crude oil: the world price of the raw material.
- Refining: turning crude into petrol and diesel.
- Tax and duty: often the largest part, and very different between countries.
- Transport and retail: shipping, storage and the station's margin.
- Your currency: oil is priced in dollars, so a weaker currency makes fuel cost more.
- Government rules: some countries set the price or subsidise it, so it may not follow the world price.
