(And one not directly addressed in the archives.) The MBz can that I use has only one sealing surface (the oblong cap). All other components are welded with an internal surface that has a lower level of friction than a bare metal surface. I assume it has been coated with an anticorrosive film to minimize rust buildup. (Not the case with the classic VW spare gas cans). These films are typically a well bonded fully aliphatic coating not attacked by hydrocarbons. Some of these coatings are attacked by alcohols. The cap seal is Viton and therefore impervious to all solvents at any anticipated temperature. the emergency gas formulations should be compatible with the extensive gas tank interior coatings, so I suspect that all is well. Nonetheless, I store gasoline in the container. the device is designed so that you can't easily overfill the unit and the cap seal is impressive. In releasing the cap, the can is vented, so I just don't see a problem. Besides, I have opened the spare tire area, taken out the spare tank and used its elixir without uncomfortable burning sensations on the hand (after a strong midsummer central valley run - hot). The temperature of the gas cannot exceed the temperature of the exiting airflow from the radiator. The air temperature cannot exceed the coolant temperature so the absolute max is 100C. The realistic actual temperature is more like 60 C. NBD! So, I think its fine, tests required for empirical certitude. Frank Grunthaner
