ll Capacities
•
“ASTM D975”, Grade 1D S15, and Grade 1D S500
•
“JP7 (MIL-T-38219)”
•
“NATO F63”
Note:
JP7 and NATO F63 can only be used if the
sulfur level meets the speci
fi
cations that are listed
in tables 37 and 38. An analysis of a sample of fuel
must be conducted in order to check the sulfur level.
Group 3 Speci
fi
cations (Aviation Fuels)
This group of fuel speci
fi
cation must be used only
with the appropriate fuel additive. This fuel WILL
reduce engine life and performance.

Note:
All the above fuels can ONLY be used if the
sulfur level meets the speci
fi
cations that are listed
in tables 37 and 38. An analysis of a sample of fuel
must be conducted in order to check the sulfur level.
Note:
These fuels are only acceptable provided
that these fuels are used with an appropriate fuel
additive. These fuels must meet the requirements
that are stated in tables 36, 37 and 38. Fuel samples
should be analyzed for the compliance. These fuels
MUST NOT exceed lubricity wear scar diameter of
0.46 mm (0.0181 inch). The fuel lubricity test must be
performed on a HFRR, operated at 60 °C (140 °F).
Refer to “ISO 12156-1 ”. Fuels must have minimum
viscosity of 1.4 centistokes that is delivered to the fuel
injection pump. Fuel cooling may be required in order
to maintain minimum viscosity of 1.4 centistokes that
is delivered to the fuel injection pump.
Group 4 Biodiesel
Biodiesel is a fuel that can be de
fi
ned as mono-alkyl
esters of fatty acids. Biodiesel is a fuel that can
be made from a variety of feedstock. The most
commonly available biodiesel in europe is Rape
Methyl Ester (REM). This biodiesel is derived from
rapeseed oil. Soy Methyl Ester (SME) is the most
common biodiesel in the United States. This biodiesel
is derived from soybean oil. Soybean oil or rapeseed
oil are the primary feedstocks. These fuels are
together known as Fatty Acid Methyl Esters (FAME).
Raw pressed vegetable oils are NOT acceptable for
use as a fuel in any concentration in compression
engines. Without esteri
fi
cation, these oils gel 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 a variety of other feedstocks. In order to use
any of the products that are listed as fuel, the oil
must be esteri
fi
ed.
Note:
Engines that are manufactured by Perkins
are certi
fi
ed by use of the prescribed Environmental
Protection Agency (EPA) and European Certi
fi
cation
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.
Recommendation for the use of biodiesel
The neat biodiesel must conform to “EN14214”
or “ASTM D675” regulations. A maximum of 10%
mixture of biodiesel can be used in mineral diesel fuel.
The mineral diesel fuel must conform to “EN590”,
“ASTM D975” or “BS2869 Grade A2” regulations.
In North America, biodiesel and mixtures of biodiesel
must be purchased from the BQ9000 authorized
manufacturers and BQ9000 certi
fi
ed distributors.
In other areas of the world, the use of biodiesel that is
authorized and certi
fi
ed by an appropriate biodiesel
quality body is required.
Note:
When biodiesel, or any blend of biodiesel is
used, the user has the responsibility for obtaining the
proper local exemptions, regional exemptions, and/or
national exemptions that are required for the use
of biodiesel in any Perkins engine that is regulated
by emissions standards. Biodiesel that meets
“EN14214” is acceptable. The biodiesel must be
blended with an acceptable distillate diesel fuel at the
maximum stated percentages. However, the following
operational recommendations must be followed:
