Notes:
1) Unleaded fuel only. Can be run on 91 octane unleaded . • RON stands for Research Octane Number, and is a measure of the ability of the fuel to withstand knocking. MON stands for Motor Octane Number, another way of measuring the same property .
(R+M)/2, also called AKI (Anti Knock Index) is a combination of these two measurements . 95 RON is equivalent to 91 (R+M)/2. 91 RON is equivalent to 87 (R+M)/2 .
