The octan rating here in Europe is different to the US.

http://en.wikipedia.org/wiki/Octane_rating :
In most countries, including all of those of Europe, and Australia, the "headline" octane rating shown on the pump is the RON - but in the United States, Canada, and some other countries, the headline number is the average of the RON and the MON, called the Anti-Knock Index (AKI). It may also sometimes be called the Road Octane Number (RdON), Pump Octane Number (PON), or (R+M)/2.

As you can see in the table on the wikipedia page US-regular 87 is equivalent to European 91, US-91 equivalent to "EuroSuper" 95 and US-premium 93 equivalent to European "SuperPlus" 98.
At big gas stations in Europe you can also get "SuperPlus 100".

So in Europe we don't use higher rated gasoline, there are just different calculation methods.
