Go ahead and have yourself some experiments with gasoline and a few different petro-chemical based compounds (plastics - nylons - polyesters - etc.) as well as some natural rubber. After dissolving a few things in the gasoline, please come back and comment. No, we are not talking Aqua Reggia here, but, over time, some compounds will degrade in gasoline - compunds that would be more or less perfectly safe in water.
