E5 is not a RON number
E5 describes ethanol content, while RON describes octane rating.
Search recent E5 premium petrol prices near you. Route & Fuel shows likely RON 97+ prices when the fuel name is clear, but the pump label is the final check.
E5 identifies ethanol content, not a precise octane rating. Use the result as a local premium-petrol search and verify RON 97+ on the pump.
Prices can change after publication. Check the update time and forecourt display before travelling.
The octane rating, retailer product and vehicle requirement all matter.
E5 describes ethanol content, while RON describes octane rating.
A premium product may be RON 97, RON 98 or RON 99 depending on the retailer.
Use the minimum grade specified in the owner's manual or by the vehicle manufacturer.
Use the time the price last changed, fuel grade and route context together.
Many UK super unleaded products are E5, but the E5 label alone does not prove a specific RON rating.
RON 99 has a higher octane rating. Whether that benefits a vehicle depends on its engine design, calibration and manufacturer guidance.
Yes. The RON 99 page uses recognised fuel names and still asks drivers to verify the exact product at the pump.
Route & Fuel separates official national statistics from station-level prices. The latest station-level price update used on this page is dated 24 June 2026; typical ranges reduce the effect of unusual reports instead of presenting one extreme price as a guaranteed bargain.
