Actually, it is a number indicating the degree of knocking of a fuel
mixture under standard test conditions. pure normal heptane is
arbitrarily assigned a rating of 0 and isooctane is assigned 100, making
the amount of knocking in the test engine of a liquid rated at 80 is the
equivalent of 80 parts heptane, 20 parts isooctane. to get octane
results of over 100 require the addition of lead alkyl
products[tetraethyl or tetramethyl lead iirc]. there is a chemical known
as n-octane, c8h18 or ch3[ch2]6ch3 used as a solvent and in the iso form
for callibrating testing aparatus.
