The gasoline we bought in the good ol' days with "100+ octane" was rated by
different methods, Research Octane Number [RON] or Motor Octane Number
[MON]. Gasoline is now rated by averaging these two ratings [R+M/2].
There are several good gasoline articles on the web for those less
technologically challenged than I, such as
