FUEL PROBLEM SOLVING
What problems are there? and how
we can help you...
Some Common Fuel Problems
Water, rust and dirt accumulate in the bottom of storage tanks. Water comes either
from leakage and/or condensation. Fuel in storage tanks can sometimes
develop a dirty slime at the fuel/water interface. Apart from being
unsightly it can block tank strainers and vehicle fuel filters. If left
unattended it can spoil the fuel
and contribute to tank corrosion.
The oxidation process of fuel results in the production of gums and
The most common contamination is from Cladisporium
These airborne spores which occur naturally in diesel, have an oxygen source
from the water and use the elements as a food source to propagate growth. It
becomes evident because of the fact that filters clog up, vehicles may
lose power and their overall performance deteriorates.
The conventional method of eradicating the bug is to use a biocide. However,
this has two major drawbacks in that both the water and the dead bug remains
in the system and removal is costly.
WAXES and RESINS
Sulphurous acids cause the build up of waxes and resins on injector pintels
and, which may leach into oil components. The warnings are piston
rings sticking or the rings and cylinder lines wearing to the point of
excessive blow-by or oil consumption. As these warnings are not
dramatic but accurate over time, engine users attribute the gradual drop in
performance due to the age of the vehicle.
During combustion, sulphur in fuel forms various sulphur oxides which
combines with the moisture in the intake air to produce sulphuric acid. This
acid accumulates in the engine lubricating system. Suspended in the oil, it
chemically attacks cylinder lines, piston rings, exhaust valve guides and
other engine parts.
The problem can get worse:-
the running hours of the engine, the greater the fuel consumption so the
greater sulphur intake
The higher the sulphur content through minimal refining, the larger the
High humidity aggravates fuel sulphur wear
When engines operate at lower than normal temperatures, moisture
condensation increases. This depletes the oil additives and
combines with the sulphur in the fuel to make more acid
Micro-organisms will consume
rubber gaskets, O-rings, hoses, tank linings and coatings in an effort
to obtain their mineral content. Fuel bugs pose a major threat to
equipment. They can double in population every 20 minutes, eventually
they will form a mat of black, brown or green slime, which poses a
serious hazard to both equipment and storage facilities.

HOW WE HELP YOU
are the sole importers, in Spain, of Fuel Set from Australia.
It is used as a
fuel conditioner for all engines. See our Fuel Set page
We also offer a
complete Fuel Polishing System, whereby we remove fuel from the tank,
clean and decontaminate it, and return the cleaned fuel back to the tank.
