Can you still buy 98 octane at the pumps where you live?

I have to correct myself. Octane in Europe is measured using the RON (Research Octane Number) while the US uses the PON (Pump Octane Number). 98 RON is the same as 94 PON. Once I found this out, I had to contact my shop before it purchased the pistons to tell the guys there I wanted to bring the compression down to 10:1 just to be on the safe side.
