These fuels should have a wear scar value of 650
micrometers maximum *HFRR to ISO 12156 - 1.*
Group 3 (aviation kerosene fuels): Specification
These fuels need additives to achieve lubricity of 650
micrometers wear scar and the reliability of the fuel
injection pump will be reduced. The fuel injection
pump is not covered by a warranty, even when the
additives are included.

Low temperature fuels
Special fuels for use in cold weather may be available
for engine operation at temperatures below 0 °C
(32 °F). These fuels limit the formation of wax in the
fuel oil at low temperatures. If wax forms in the fuel
oil, this could stop the flow of fuel oil through the filter.
Note: These fuels that lack lubricity may cause the
following problems:
•
Low engine power
•
Difficult starting in hot conditions or in cold
conditions
•
White smoke
•
Deterioration of emissions and misfire at certain
operating conditions
Biofuel: Specification
Biofuel: A 5% mix of RME to EN14214 in conventional
fuel is permitted.
Water emulsion fuels: These fuels are not permitted
Refer to the following fuel specifications for
North America.

NOTICE
The preferred fuels provide maximum engine service
life and performance. The preferred fuels are distillate
fuels. These fuels are commonly called diesel fuel
or gas oil.
The permissible fuels are crude oils or blended fuels.
Use of these fuels can result in higher maintenance
costs and in reduced engine service life.
Diesel fuels that meet the specifications in Table
14 will help to provide maximum engine service life
and performance. In North America, diesel fuel that
is identified as No. 2-D in "ASTM D975" generally
meets the specifications. Table 14 is for diesel fuels
that are distilled from crude oil. Diesel fuels from
other sources could exhibit detrimental properties
that are not defined or controlled by this specification.
