Raw pressed vegetable oils are NOT acceptable for
use as a fuel in any concentration in compression
engines . Without esterification, these oils solidify in
the crankcase and the fuel tank. These fuels may not
be compatible with many of the elastomers that are
used in engines that are manufactured today. In
original forms, these oils are not suitable for use as a
fuel in compression engines . Alternate base stocks
for biodiesel may include animal tallow , waste
cooking oils , or various other feedstocks. In order to
use any of the products that are listed as fuel, the oil
must be esterified .
Fuel made of 100 percent FAME is generally referred
to as B100 biodiesel or neat biodiesel.
Biodiesel can be blended with distillate diesel fuel.
The blends can be used as fuel. The most commonly
available biodiesel blends are B7, which is 7 percent
biodiesel and 95 percent distillate diesel fuel.
Note: The percentages given are volume-based.
The U.S. distillate diesel fuel specification ASTM
D975-09a includes up to B5 (5 percent) biodiesel.
European distillate diesel fuel specification EN590
includes up B7 (7 percent) biodiesel. Any diesel fuel
in Europe may contain up to B5 or in some regions up
to B7 biodiesel fuel.
Note: Engines that are manufactured by Perkins are
certified by use of the prescribed Environmental
Protection Agency (EPA) and European Certification
fuels. Perkins does not certify engines on any other
fuel. The user of the engine has the responsibility of
using the correct fuel that is recommended by the
manufacturer and allowed by the EPA and other
appropriate regulatory agencies.
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 very cold
temperatures that are below −18 °C (−0.4 °F).
Aftermarket Fuel Additives
Supplemental diesel fuel additives are not generally
recommended . This recommendation 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. 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 20 .
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. The
use of the fuel is in order to remove deposits 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 cleaner 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 engine 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.
Perkins 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 control catalysts and particulate
filters. Perkins fuel system cleaner contains less
than 15 ppm of sulfur and is acceptable for use with
ULSD fuel.
