General Requirements
Biodiesel and biodiesel blends are known to cause an
increase in fuel system deposits, most significant of
which are deposits within the fuel injector. These
deposits can cause a loss in power due to restricted
or modified fuel injection or cause other functional
issues associated with these deposits. Perkins
T400012 Fuel Cleaner is most effective in cleaning
and preventing the formation of deposits. Refer to
“Perkins Diesel Fuel System Cleaner” for more
information. Perkins UMK8276 Perkins Diesel Fuel
Conditioner helps to limit deposit issues by improving
the stability of biodiesel while also hindering the
production of new deposits. For more information
refer to “Perkins Diesel Fuel Conditioner”.
Diesel fuels blends with FAME are not recommended
in applications that are infrequently used and may be
stored for long periods. Examples are, standby
generator sets and certain emergency vehicles. This
recommendation is due to FAME having reduced
oxidation stability compared to hydrocarbon diesel.
Use of FAME can result in the formation of acids and
solid precipitates.
If biodiesel must be used, then the quality of the fuel
must be tested periodically. In particular the stability
of the fuel must be tested and comply with EN 15751,
commonly known as the Rancimat test.
Perkins strongly recommends that seasonally
operated engines have the fuel systems, including
fuel tanks, flushed with conventional diesel fuel
before prolonged shutdown periods. An example of
an application that should seasonally flush the fuel
system is a combine harvester.
Microbial contamination and growth can cause
corrosion in the fuel system and premature plugging
of the fuel filter. Consult your supplier of fuel for
assistance in selecting appropriate antimicrobial
additive.
Water accelerates microbial contamination and
growth. When biodiesel is compared to distillate fuels,
water is naturally more likely to exist in the biodiesel.
Ensure that you check frequently and if necessary,
drain the water separator.
Materials such as brass, bronze, copper, led, tin, and
zinc accelerate the oxidation process of the biodiesel
fuel. The oxidation process can cause deposits
formation therefore these materials must not be used
for fuel tanks and fuel lines.
Fuel for Cold Weather Operation
The European standard “EN590” contains climate
dependant requirements and a range of options. The
options can be applied differently in each country.
There are five classes that are given to arctic climates
and severe winter climates. 0, 1, 2, 3 and 4.
Fuel that complies with “EN590” CLASS 4 can be
used at temperatures as low as −44 °C (−47.2 °F).
Refer to “EN590” for a detailed discretion of the
physical properties of the fuel.
The diesel fuel “ASTM D975 1-D” used in the United
States of America may be used in cold temperatures
that are below −18 °C (−0.4 °F).
In extreme cold ambient conditions, you may also use
Aviation, kerosene fuels specified in “Group 2:
Aviation Kerosene Fuels”. These fuels are intended
to be used in temperatures that can be as low as
−54 °C (−65.2 °F). for more information, refer to
“Group 2: Aviation Kerosene Fuels”for detail and
conditions of use of the aviation kerosene fuels.
Aftermarket Fuel Additives
NOTICE
Perkins does not warrant the quality or performance
of non-Perkins fluids and filters.
When auxiliary devices, accessories, or consumables
(filters, additives) which are made by other manufac-
turers are used on Perkins products, the Perkins
warranty is not affected simply because of such use.
However, failures that result from the installation
or use of other manufacturers devices, accesso-
ries, or consumables are NOT Perkins defects.
Therefore, the defects are NOT covered under the
Perkins warranty.
Supplemental diesel fuel additives are not
recommended and is due to potential damage to the
fuel system or the engine. Your fuel supplier or the
fuel manufacturer will add the appropriate
supplemental diesel fuel additives.
Perkins recognizes the fact that additives may be
required in some special circumstances. Fuel
additives need to be used with caution. Contact your
fuel supplier for those circumstances when fuel
additives are required. Your fuel supplier can
recommend the appropriate fuel additive and the
correct level of treatment.
Note: For the best results, your fuel supplier should
treat the fuel when additives are required. The treated
fuel must meet the requirements that are stated in
table 21 .
Perkins Diesel Fuel System Cleaner
Perkins T400012 Fuel Cleaner is the only fuel
cleaner that is recommended by Perkins .
If biodiesel or biodiesel blends of fuel are to be used,
Perkins require the use of Perkins fuel cleaner. For
more information on the use of biodiesel and
biodiesel blends refer to “Biodiesel Fuel”.
