The useful answer: choose the correct fuel grade, check when the price was reported, open the station details, compare the extra drive and only then open directions. The lowest pump price is not automatically the lowest-cost stop.
1. Select the fuel your vehicle actually uses
Compare like with like. E10 and super unleaded E5 are different grades. Standard diesel B7 and premium diesel are also different products. Start with the grade required by your vehicle handbook, then compare stations that report that same grade.
2. Read the price update time
A published price is a reported record, not a promise that the forecourt display has not changed since. Prefer recent records, note the update age and treat the pump display as the final check before buying.
3. Open the station detail page
A useful fuel finder should lead beyond a map pin. Check the station name, postcode, latest reported prices, opening information, facilities and recent history. Route & Fuel search results link to detailed station pages as well as Google Maps.
4. Count the detour before calling it a saving
First calculate the gross pump saving:
Then subtract the fuel used by the extra miles. An optional time value can also be included when a detour adds a meaningful delay.
A transparent worked example
Suppose one station is 8p per litre cheaper and you plan to buy 45 litres. The gross pump saving is £3.60. A four-mile total detour in a car returning 45 UK MPG uses about 0.40 litres. At £1.50 per litre, that extra fuel costs about 61p. The estimated fuel-only saving is therefore about £2.99 before any value is placed on the extra time.
The same 8p gap would be less attractive for a small top-up, a longer detour or slow stop-start traffic. Use the journey cost calculator to change the assumptions.
5. Open directions after choosing the stop
Once the price, freshness and detour still make sense, open the station in Google Maps. Plan before setting off or while safely parked. A fuel finder should support the decision, not encourage interaction while driving.
Nearby fuel finder or fuel along my route?
A postcode search is best when you need a local comparison. A route search is better for a longer journey because a station can be cheap but sit in the wrong direction. Route & Fuel uses the same answer-first approach on both: a working search, detailed station information and a route-aware calculation.

Android · iPhone and iPadFuel finder app questions
What should I check first in a fuel finder app?
Check the fuel grade, reported price, update time and distance. A low price can be misleading when it is old or requires a long detour.
Should I choose the cheapest or nearest station?
Neither rule works every time. Compare the expected pump saving with the extra fuel and time needed to reach the station.
Can I use a fuel finder app while driving?
Plan before setting off or while safely parked. Route & Fuel can pass the selected station to Google Maps after the decision is made.
Does Route & Fuel work on Android and iPhone?
Yes. Route & Fuel has dedicated Android and iPhone or iPad download pages, plus a free postcode finder on the website.
