Reading this link should answer your questions fully.

Just bought a 1980 300Sd that had been parked for three years. The fuel was dark brown from the critters living in it. I drained about nine gallons into two five gallon Nalgene jugs with the intention of dumping it. I pulled and cleaned both tanks, cleaned the screen, replaced the rubber fuel lines, and blew out the feed and return lines. I put in about ten gallons of fresh fuel with new filters and a shot of Biobor and that made the car happy again. Just for fun I gave one of the jugs a shot of Biobor too. In two days the treated jug was clear enough to see the bottom so I treated the other one. A week later I ran it through a 5 micron filter to get rid of the goo and used it in my daily driver.

Most impressive thing I've seen with Biobor is the treatment of 8,000 gallons of continated fuel in a boat. They shocked the tanks with Biobor and two days later came back and pumped the fuel into their holding tank while they flushed the tanks with 15 gallons of kerosine. They saved his fuel, cleaned his system, charged him $500 and gave him a one year warranty.

Like most car maintenance this is another area where prevention is the best approach. Generally, algae in the fuel is preceded by water in the fuel. Generally, fuel that is kept free of water is also free of algae.

That point having been made, I consider it cheap insurance to treat your fuel with a biocide a few times a year to curb this problem before it gets out of control.

How about dumping a couple cans of HEET into the tank? Supposedly it works for diesel too.

I used BioGuard (made by ValvTect) on someone else's recommendation. Got it at Outdoor Superstore for $13 plus $6 shipping (Price increased to $15 now). Put a clean prefilter on, dumped it in my tank. Drove to work the next morning and the prefilter was already clogged with the black stuff. Soon as the tank is low, I'm changing out the tank filter (already had one on hand).

Fungus is like the clapp: You don't geyt it unless you get exposed to it. Fungus doesn't come out of the air: you have to get fuel contaminated with it. So what is I'm saying is that Biobor is not preventive mintenence. Its only needed if you have a fungus contaminated fuel system.

I have been using Diesel engines for 40+ years and only has a fungus problem one time. That was in my '80 300SD that has been in all the startes less one. Someplace in those travels, I got contaminated fuel and had to use Biobor to kill the fungus.

Since using the Biobor 10,000+ miles I had to replace one inline fuel filter and did no other cleaning fo the fuel system.

.........but then how did the contaminated fuel get contaminated?

T walgamuth,

U don't need water in tank for fungus to grow, it actually lives off the Diesel fuel.

U get fungus by buying contaminated Diesel fuel.

Biobor is best fungus killer, but its expensive. I paid $40 for a quart and $40 more for shipping because its considered a hazardous substance.

Starbrite's Startron diesel enzyme fuel additive in the diesel tank...no further
worries...breaks down the Fungoidal infestation into particles small enough to
pass through the filters and burn in the engine.

AKLIM,

HEET is ALCOHOL which is hygroscopic (attracts water molecules...bonds with
the water molecules...F***s up the Injectors,I.P.and Engine).

europower,

U can't know in fact that U have algae because algea does not grow in oil.

What U might have is a fungus that will grow in oil.

while I'm sure the majority of this page is a sales pitch... http://www.neptuneproducts.co.nz/shop/Articles/DIESEL+Fuel+bugs.html

Quote:

Diesel fuel "bugs" are actually micro-organisms comprised of fungi, yeasts and bacteria which live mostly in the diesel / water interface inside the diesel tank. The common diesel ‘bug’ is the fungus Hormoconis resinae that can produce a large biomass of mycelia (fungal matting) in a short period of time if the conditions are favourable. Hormoconis resinae is called "diesel bug" in the diesel fuel industry and "jet fuel fungus" in the aviation industry.

The mycelia of Hormoconis resinae excrete acids that can break down weaker tank material such as aluminium.

Water, nutrients and warmth are the pre-requisites for micro-organisms to rapidly grow, blocking filters and damaging engine fuel components. Water can be either free water (fresh or salt) or emulsified water. Nutrients can include the alkanes in the fuel, dead micro-organisms and even the fuel tank material. Warmth is usually from the local ambient conditions, but diesel tanks in engine rooms and non-cooled high flow return lines into small tanks will increase the diesel tank temperature.

Long storage of diesel fuel also increases the potential of microorganisms to grow.

I do KNOW that the Startron product will eliminate the FUNGUS (AND Bacteria)
with out clogging the filters.

E.P.,

There's no dosage requirement,since it's an enzyme solution,all a larger dose
does is achieve cleanliness a little quicker.
The container does say 1 Oz. per 16 gals for initial treatment
AND
1 Oz. per 32 gals for maintenance.

BUT,I called Ft. Lauderdale in 2008 and Starbrite (The Manufacturer) told me
a Quart in a 13 Gal. tank would not hurt anything.

I've got 4 gals of Diesel that I put 16Oz. of Startron into in 2006,and it still
won't grow anything in it.
(Of course, it's a closed system, so no way for H2O or any other trash to get in.)

I got a bottle of the Biobor JF from West Marine and it seems to have cleared up my issues in my 300D. I was going through fuel filters every three weeks.
