Will gasoline melt a milk jug?
Milk jugs, anti-freeze jugs, glass containers and many ‘gas cans’ are not suitable for carrying or storing gasoline. Some plastics become brittle with age and are incompatible with gasoline. Other containers are not strong enough to withstand the pressures of expansion and contraction caused by temperature changes.
Will gas eat through plastic bottle?
The hydrocarbons in gasoline interact freely with those in the plastic. If the interaction between gasoline and the plastic is less energetic than that of the bonds in the plastic, the plastic will dissolve.
