Petrol and diesel are separate decisions
These are price averages for different fuel grades, so compare the grade your vehicle actually uses.
E5, RON 97+ and RON 99 describe different things
E5 is an ethanol-content label. RON is an octane rating. A product may be E5 and RON 97, 98 or 99.

Premium availability before you travel
Use the fuel grade, availability and last-updated time together.
Does premium fuel mean petrol or diesel?
It can mean either. This page separates E5 super unleaded, RON 97+ and RON 99 petrol from premium diesel so unlike grades are not compared as though they were interchangeable.
Is every E5 price definitely RON 97+ or RON 99?
No. E5 describes ethanol content. RON 97+ and RON 99 are octane ratings. Availability varies by site.
Is premium diesel the same as standard B7 diesel?
No. Premium diesel is a separate retailer category from standard B7. Availability varies by site. Follow your vehicle guidance.
About these prices
