HA! I just got my Summit 2002 Official Race Parts catalogue. On page 29 there's a special product

.
It reads:
"Why deal with the nauseous exhaust fumes from your race vehicle when you could be sniffing root beer, pina colada, or bubble gum instead?...Manhattan Oil fuel fragrance eliminates unpleasant exhaust fumes... Just mix it in with your regular fuel... You can choose from 19 different fragrances."
When I first read it, I thought it was a joke, but it is for real.
Here are some of the flavors:
Cherry Bomb
Groovy Grape
Supercharged Strawberry
Banana Blast
Victory Vanilla
Light 'em Up Licorice
Burn Out Blueberry
Turbo Tangerine
and many others....LOL
