Why brand-name premium petrol searches are different
Drivers searching Tesco Momentum 99, Shell V-Power or Esso super unleaded often know they want a premium fuel, not just the cheapest petrol. The public fuel feed usually reports the fuel as Super unleaded E5, so the exact product label needs careful handling.
Start with the vehicle requirement
GOV.UK explains that E10 is standard 95 octane petrol and E5 is the super grade at 97+ octane. If your car requires or recommends a higher RON, follow the vehicle manufacturer or tuner guidance before comparing prices.
Then compare the station and route
Once you know the right fuel grade, compare current price, station location, opening status, fuel remaining, and the detour needed to reach it. A premium fuel stop can be the right decision, but not if it sends you on a long loop for a tiny price difference.
How Route & Fuel handles premium labels
Route & Fuel maps common retailer premium fuels into 97/99 RON context where reliable and keeps uncertain E5 products generic. That keeps the app useful without overclaiming from the public feed.
