RON stands for Resea rch Octane Number, and is a measure of
the ability of a fuel to withstand knocking. MON stands for Motor Octane Number and is another way of
measuring the same property.
(R+M)/2,
also called AKI (Anti Knock Index) combines these two
m eas urem ents .
95
RON is equivalent to 91 (R+M)/2. 91 RON i s equivalent to 87 (R+M) /2.
