During the 1960�s another complication arose in fuels with a large difference between their Motor and Research octane numbers (called the fuel�s sensitivity). This lead to trouble with some high compression engine on high-speed roads, so in the early 1970�s the AKI method was adopted in the USA. AKI is the average of RON and MON and is a better indicator of any fuel with a high sensitivity, when only one octane number is advertised.
To reduce consumer confusion over different octane numbers, the USA passed laws so that AKI is the octane rating shown on pumps at petrol stations in that part of the world. Because of this it is also sometimes called the Pump Posted Octane Number.
Other versions of the CFR engines are used for aviation fuels (with supercharging) and for diesel fuels to get Cetane ratings.
