I'm buying diesel 5 gallons at a time and generally empty it into the tractor when I get home. My thought was that I didn't really want to keep a full can around due to the gelling (winter) or the fungus stuff (summer) that I've read about. Now i'm wondering about the small amount of leftover fuel in the can until the next fill up. Should I be using a fungus inhibitor in the can between fill ups? It does get pretty hot in the garage in the summer.
