I agree, the fuel in the tank is worth 2 in the bush so to speak. Fill up when you can. They are asking everyone to only get what you need, but that is like Communism and socialism, it looks good on paper but won't work in the real world. You scrimp by only to have the next guy take it all. Save the empties, fill up when you can, and maybe you will have extra to help your fellow man when you can.
