E5 and RON describe different properties
E5 describes ethanol content of up to 5%. RON describes octane rating. Availability varies by site.
RON 97+
The broad UK super-grade description used in government guidance.
Local availability
Availability varies by site.
The current E5 average is 17.60p/l above E10
At that gap, the website's standard 55-litre comparison costs about £9.68 more. Whether that is worthwhile depends on vehicle requirements and measurable benefit, not the word “premium” alone.
Before you fill up
A fuel price is useful only when you know the grade, when it changed and whether the extra journey is worth it.
Is all super unleaded RON 99?
No. UK super unleaded is generally RON 97+ rather than universally RON 99. Availability varies by site.
Can an E10-compatible car use E5?
Official UK guidance says an E10-compatible petrol vehicle can use E5 and can mix E5 with E10. Follow the owner's manual for octane requirements.
Will super unleaded always improve performance?
No. Benefits depend on engine design, calibration, condition and driving. A car that only requires 95 RON may not deliver a financial return from the price premium.
