Alcohol which has a low octane rating although it keeps getting credit

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.

Hexane, Heptane, Octane, ...actually it doesn't have anything to do
with the number of nanes...:-))

It's an anti-knock rating. The lower the number the more prone to
spark knock (detonation) the fuel would be under compression.
