FuelRank guide
Petrol vs diesel price trends in the UK
Understand why petrol and diesel prices move differently and how to compare them locally.
Petrol and diesel do not always move together
Wholesale costs, seasonal demand, refining capacity, and retailer strategy can all move petrol and diesel prices at different speeds.
Local competition matters
Supermarkets and busy commuter routes can create local price pressure. Rural stations or motorway services often behave differently from city forecourts.
Compare your actual area
National averages are useful context, but your decision is local. FuelRank is designed around nearby station comparisons rather than only headline averages.
