This was an old trick to extend a low tank of gas, do not try it on cars with modern fuel injected engines.

Naphthalene mothballs will dissolve in the gasoline, providing more hydrocarbon "fuel". But it does not vaporize as easily as gasoline and could cause plugging up of fuel injectors. Older engines with carburetors were more tolerant of thios than fuel injected ones..
