I lifted this from about.com
Gasoline pumps typically post octane numbers as an average of two different 
values. Often you may see the octane rating quoted as (R+M)/2. One value is 
the research octane number (RON), which is determined with a test engine 
running at a low speed of 600 rpm. The other value is the motor octane 
number (MON), which is determined with a test engine running at a higher 
speed of 900 rpm. If, for example, a gasoline has an RON of 98 and a MON of 
90, then the posted octane number would be the average of the two values or 
94.

I think the difference you are seeing between your octane numbers an the 
ones used in the USA are just different ways of calculating the octane.
