The core idea
Cheap fuel is only useful if getting to it does not wipe out the benefit. Route & Fuel is built to keep that comparison visible in the app.
What the local website figures mean
Cheapest vs local average compares the cheapest listed result with the average of the matching station prices shown. Cheapest vs highest local price compares the cheapest with the highest listed result. Both use a 55-litre example fill to keep postcode pages consistent. They exclude detour fuel and show price differences rather than money already saved. Enter your litres in the calculator or app for a personal comparison.
How the app talks about it
The nearby check starts with the local station price. The journey check then adds where the stop sits on your route, the extra fuel needed to reach it and any live-traffic delay, so the app can show the saving that is likely to remain before you commit.
Inputs the saving can use
Example saving after extra driving flow
- Compare selected station prices against the explicitly shown nearby or on-route benchmark.
- Calculate the pump-price difference using the litres you expect to buy.
- Calculate detour fuel from the route and planning MPG.
- Show detour time with live traffic separately, and show current-fuel reachability as an estimate rather than a guarantee.
- Show the remaining calculated saving clearly before the driver commits.
Why this matters
Without route, planning MPG and tank details, every driver can be shown the same “cheap” result. Route & Fuel uses those inputs to make the comparison more useful for the specific driver and journey.
Important note
Fuel prices, availability and journey conditions can change. Route & Fuel is decision support, not a guarantee. Use the displayed price-change time when comparing results.
