There are numerous elements that make up the price of a litre of petrol or diesel, primarily:
a) Government duty and tax
b) The cost of petrol and diesel on the open market - cost of product
c) The costs and profit of the wholesaler and retailer - Retail/Ex-Refinery spread
The other factors affecting the price include exchange rates, competition, commercial objectives of the filling station owner or operator, as well as seasonal factors.
Taxation remains the largest component of the pump price.
