Hunter,
Went to the thread you directed, but failed to see the point. There was no new info there.

Sixto,
Now that you have explained the situation, I think I see why you had a FUNGUS problem. Diesel cars and diesel fuel storage tanks can't be left idle and particularly in a low fuel state. You should always fill your tank before you park the car for an extended period of time. To splain what happens we all need to know that the stuff that grows in the tank is FUNGUS and not ALGAE. Algae is reproduced through photosynthesis which requires sun light. I don't know about you guys, but the inside of my tank is one place the sun don't shine. Fungus forms in your tank when there is water in the fuel. Fungus lives in the water and lives on the fuel. Where does the water come from? Here's where the low level of fuel in the tank comes in. As the ambient temp changes from hot afternoons to cool evenings, the walls of the tank sweat and produve water. It doesn't take too many days before you have a perfect environment for colonies of fungus to form. I have logged thousands and thousands of MB diesel miles and never put anything in my tank, but of course I live in Ca. I'm sure conditions are different in places like the South where the humidity is unreal. It may be necessary to treat fuel in those places. I lived in Virginia for 4 years and I could never get dry.
