Forgot to say..
In the UK the ordinary stuff is called 'Premium' and it's 95 RON (87 to you).
The better stuff is usually called 'Super' and is 98 or 97 RON (92 or 93AKI).
Also there is LRP (Lead Replacement Petrol) which is 97 RON. This is for cars designed to run on leaded fuel (we are thirty years behind the US on this one!). This one is starting to get difficult to find.
Mainland Europe seems have 95 & 98 RON.
