Those are higher Octane numbers than we see over here (92 to 93 is our best).

The numbers for the octane rating in Europe and the US are calculated differently. In Europe, they use RON (Research Octane Number). In the US, it's the average of RON and MON (Motor Octane Number), which is usually a lower value.
