FuelRank guide
Fuel savings calculator: is the cheaper station worth it?
See how to calculate whether driving to cheaper petrol or diesel actually saves money after the round-trip fuel cost.
Start with the pump-price saving
Multiply the price difference by how many litres you plan to buy. A 5p per litre saving on 40 litres is £2 before travel costs.
Subtract the round-trip fuel used
FuelRank estimates the fuel burned getting to the station and back from the distance and your MPG. That travel cost is then included in the total fill-up cost.
Compare the real totals
The best station is the one with the lowest combined cost, not always the lowest sign price. That is why FuelRank shows a trip-adjusted per-litre price and potential saving.
