hmmm i happen to have two cans of butane around the house. one is Ronson ultra butane fuel and the other is Bernzomatic butane. i'm a little hessitant to try it becuase there is a warning on the can bernzomatic can that says this fuel, and byproducts of combustion of this fuel contain chemicals that are known to cause cancer.
how can you be sure that ALL the butane (and any other miniscule chemicals) are out of the oil?
