            Diesel Tank Contamination

Unfortunately most tanks diesel tanks have now been contaminated with the diesel bug.
Any tanks with the slightest amount of water in them provide ideal circumstances for the
diesel bug to multiply. Diesel tanks in boats, on construction sites, farms, back up
generators and earth moving equipment are especially prone to be contaminated. The
older the diesel in the tank, the bigger the chance there is contamination and rust. Water
enters the fuel tanks through condensation and unclean ways of fuelling up.

The Diesel Bugs are prolific in earth's atmosphere and are carried as spores in air and
water. They can enter diesel at any point in the supply chain through vents and filling
ports.  It is difficult to know when the fuel becomes contaminated with bugs, but once
acquired they can take an enormous amount of cost & effort to get out of the fuel
system. Twenty-seven (27) individual species of bugs are known so far to occur in diesel

The most common one is a fungus, producing slime which is hard to clean out of tanks,
fuel lines and filters. Once in the tank, it will lead to increased fuel consumption at its best
and completely blocked filters and fuel lines at the worst.

Bugs feed on diesel, kerosene, oils: crude oil products with the outcome of decomposing
it. Diesel bugs are used to clean up Oil spills - Exxon Valdez
It is quite normal to have a small resident bug population in diesel tanks. These resident
bug populations are small and have no measurable effect on the quality of the fuel.

However, within the right temperature range and in the presence of any free moisture,
the bugs begin reproducing rapidly causing an exponential growth in population.

Doubling their number every 20 minutes, bugs form microbial mats or long strings of
seaweed like structures. Bug colonies can develop into a biomass several centimetres
thick across the fuel/water interface and weigh up to 10 Kg. Producing slime and acid as
'waste products' that are carried throughout the fuel system causing many maintenance

Restricted fuel flow, uneven atomization and incomplete combustion   caused by slime
build up in the fuel lines, filters and injector needles.

Cylinders develop cool spots causing uneven wear to the rings and cylinder bores. Acids
and gums can eventually leach into the lubricating oil, causing corrosion of the crank

Some species create acids that remove ions from the atomic structure of metals: this is
the main cause of corrosion in fuel tanks, lines, pumps and injectors.

Fuel Bugs cause corrosion What appears to be a rust problem can in hind site be a
problem of contaminated fuel.

Biocides have been widely used to kill bugs in diesel. Biocides may kill much of the bug
population; however, the dead population drops to the bottom of the tanks and forms
sludge. That sludge will eventually lead to increased use of filters or complete blockage.
Proper Fuel Cleaning and De-Bug Units like the Fuel-Mag eliminate all fuel bugs.

We can help you to keep your diesel tanks and engines clean, reliable and cost effective.
