How Route & Fuel groups each premium fuel
Tesco Momentum 99, Shell V-Power Unleaded and Esso Synergy Supreme+ 99 appear in the RON 99 search. Texaco Supreme appears in the wider RON 97+ search because availability and octane can vary by site.
Each retailer also makes product claims about cleaning, protection or performance. The effect can vary by vehicle, so use those claims as product information rather than a promise of better MPG.

Super unleaded E5 and E10 average prices
This chart shows recent national grade averages. It does not compare retailer formulations or confirm site-level availability.
How to choose between them
- Use the grade shown on the fuel flap, in the owner's manual or in manufacturer guidance.
- Compare nearby station prices instead of assuming one brand is always cheaper.
- Include the extra distance and the number of litres you expect to buy.
- If premium petrol is optional, compare cost per mile across several similar fills before drawing a conclusion.
Check the full journey cost
A cheaper RON 99 pump can still cost more overall if it takes you well away from the route. Compare the same fill size, MPG and extra distance in the journey calculator.
In the app, you can compare RON 99 stops along your route, see the extra miles for each detour and use your car’s MPG and fuel remaining before choosing.
