Refill Capacities
Water accelera
tes microbial contamination and
growth. When biodiesel is compared to distillate
fuels, water is naturally more likely to exist in the
biodiesel. It
is therefore essential to check frequently
and if necessary, drain the water separator.
Materials su
ch as brass, bronze, copper, led, tin, and
zinc accelerate the oxidation process of the biodiesel
fuel. The oxidation process can cause deposits
formation t
herefore these materials must not be used
for fuel tanks and fuel lines.
Fuel for Col
d 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
winterclimates.0,1,2,3,and4.
Fuel that complies with “EN590 ” CLASS 4 can be
used at te
mperatures 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 very cold
tempera
tures that are below −18 °C (−0.4 °F).
Aftermarket Fuel Additives
Supplemental diesel fuel additives are not generally
recommended. This recommendation is due to
potent
ial 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. Contact
your f
uel supplier for those circumstances when
fuel additives are required. Your fuel supplier can
recommend the appropriate fuel additive and the
corr
ect level of treatment.
Note: For the best results, your fuel supplier should
trea
t the fuel when additives are required. The treated
fuel must meet the requirements that are stated in
table 19.
Perkins Diesel Fuel System Cleaner
Per
kins 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. The use of the fuel is in order to remove
de
posits within the fuel system that is created
with the use of biodiesel. For more information on
the use of biodiesel and biodiesel blends refer to
“
Recommendation for Biodiesel”.
Perkins fuel cl
eaner will remove deposits that can
form in the fuel system with the use of biodiesel and
biodiesel blends. These deposits can create a loss
of power and en
gine performance.
Once the fuel cleaner has been added to the fuel,
the deposits
within the fuel system are removed
after 30 hours of engine operation. For maximum
results, continue to use the fuel cleaner for up to
80 hours. Pe
rkins fuel cleaner can be used on an
on-going basis with no adverse impact on engine or
fuel system durability.
Details instruction on the rate of which the fuel
cleaner must be use are on the container.
Note: Perkins fuel cleaner is compatible with existing
and U.S. EPA Tier 4 nonroad certified diesel engine
emission c
ontrol catalysts and particulate filters.
Perkins fuel system cleaner contains less than 15
ppm of sulfur and is acceptable for use with ULSD
fuel.
