Well that made me look smart.

Thanks Gilly

I always thought of octane as some configuration of carbon and hydrogen atoms and guessed that such a configuration existed in the primary constituents of gasoline and not in the primary constituents of Diesel fuel. Just as some lighter fluids are called butane and there are fluids called ethane, methane, etc., I thought there was a substance called octane. Is there no such substance or fluid called octane independent of whether or not it's in gasoline?
