Motorway fuel is convenient, but convenience has a price
Motorway service stations can be the right choice on a long journey because they are easy to access, open for longer hours and often have toilets, food and other facilities. But the best decision is not always the lowest pump price nearby.
If a nearby off-motorway stop adds distance, traffic and stress, it may not save as much as it first appears.
What to check before choosing an off-motorway stop
- Price gap: how many pence per litre you save.
- Fill amount: a large fill makes a price gap more valuable.
- Extra fuel: the extra miles to reach the station and return to the route.
- Time and traffic: a cheap station through a busy retail park may not be worth it.
- Facilities: toilets, shop, food, air and opening status can make the same stop more useful.
A practical example
If a motorway site is 10p per litre higher and you are buying 50 litres, the gross price difference is £5. That can justify a short, easy stop nearby. But if the alternative adds a long loop through traffic, the extra fuel and time may make the motorway stop more reasonable.
How the app should help
Route & Fuel is designed to surface route-aware stops and show whether the cheaper option still makes sense after detour fuel cost and live traffic timing. That means a motorway stop can still win when it is the practical choice, and an off-motorway station can win when the saving survives the detour.
