How sweet the lead smells. Which also separates the street from the airport.
My first thought was also “Brain-poisoning lead?” 
Most race fuel is unleaded…..
Race fuel is real gasoline
Pump gas is a cluster of flammable hazardous waste products that need to be disposed of mixed with enough gas so it will light easy then tempered with 10% ethanol.
In reply to Appleseed :
Although most aviation gasoline is leaded (100LL), many race fuels are not… and there is no need for lead in any fuel in this century.
Shame that race fuel isn’t available in more places, at the pump. Understandable, absolutely, but still unfortunate.
That said, about 90% of the highway driving I do is just cruising anyway, so no real need for the good stuff, and the car makes plenty of power when I do need it, on a reasonable tune.
Still remember the smell of Q17 though… Mmmm… cotton candy and most likely carcinogens…
