Alcohol which has a low octane rating although it keeps getting credit
for a high one, when added to gas up to 10% by volume will increase
the octane rating of the fuel. 10% seems to be the maximum amount for
increasing the octane rating.

Can you explain the octane rating? In my little world octane is a chain of 8
carbons with 18 hydrogens hooked on.
