We do refer to octane, but it's rated a bit differently -- RON+MON/2 = AKI, whereas most of the rest of the world uses RON.

You can get a close approximation on RON vs AKI tho'; typically .95*RON = approximately equivalent AKI.

Example: The Z recommended octane is 91 AKI and 96 RON

96 RON*.95 = 91.2, very close to the AKI value.
