Questions drivers ask
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 RON 99 the same as E5?
No. E5 describes ethanol content; RON 99 is an octane rating. Availability varies by site.
Which retailers sell RON 99?
Several UK retailers offer RON 99 fuel. Availability varies by site.
Can I use RON 99 in a car that needs RON 95?
Most petrol cars can physically use a higher octane grade, but follow the owner's manual and do not assume the price premium will be recovered.

About these prices
