If its not more powerful, then why does it give better gas mileage?

What does lead have to do with increasing the octane?  You said octane was an
indication of the number of branched chain hydrocarbons.  Does adding lead
increase the number of branched chain hydrocarbons?

Is this what all of those "octane booster" additives do?
