In the US you use another way of measure octane than we do. I believe you use two different systems, MON (Motor Octane Number) and PON (Pump Octane Number). In Europe, we use RON (Research Octane Number).
I think it is like this 98 Oktan RON is almost the same as 93 Octan PON and 95 RON is close to 91 PON. 95 RON is 87 MOM.
AKI is what you're calling PON. It's exactly what I posted. I wouldn't call it 'almost the same' unless you actually know the PON for EU. The Motor Octane number can vary quite a bit.
