How many litres you fill up in one visit. Most family cars hold 50β70L, smaller cars 35β45L. This affects how much you save on fuel price alone.

π Fuel economy
Your car's miles per gallon. Check your trip computer or car manual. Most petrol cars average 30β45 MPG. A higher number means driving further costs you less, so it's more likely to be worth going to a cheaper station.

p/litre
The app finds your nearest station to the postcode you entered. Every other station then shows whether detouring to get cheaper fuel is worth it β based on how much further it is from your postcode vs the nearest station.
Estimated net saving = fuel saving β cost of extra detour
Distance is measured from your postcode, not your actual route. If the cheaper station happens to be on your way, the real saving will be higher than shown. If it's in the opposite direction, it may be less. Use it as a guide, not an exact figure.
Search for stations to see a worked example using your postcode and real prices.
