Lubricity wear scar diameter of 0.46mm must not be exceeded. The fuel lubricity test must be performed on
a HFRR, operated at 60°C (139.9°F). Refer to 'ISO 12156-1'. Fuel additives can enhance the lubricity of a
fuel. Contact your fuel supplier for those circumstances when fuel additives are required. Your fuel supplier can
make recommendations for additives to use and for the proper level of treatment.
Distillation
This is an indication of the mixture of different hydrocarbons in the fuel. A high ratio of light weight hydrocarbons
can affect the characteristics of combustion.
Classification of the Fuels
The diesel engines have ability to burn a wide variety of fuels. These fuels are divided into four general groups.
Refer to Table 27.
Table 28.
Fuel Groups Classification
Group 1 Preferred fuels Full life of the product
Group 2 Permissible fuels These fuels may cause reduced
engine life and performance
Group 3 Aviation fuels These fuels will cause reduced en-
gine life and performance
Group 4 Biodiesel
Group 1 Specification (Preferred Fuels)
The group 1 of fuel specifications is considered acceptable:
• EN590 DERV Grade A, B, C, E, F, Class, 0, 1, 2, 3, and 4
• 'ASTM D975', Grade 2D S15, and Grade 2D S500
• 'JIS K2204 grades 1,2,3 and special grade 3' This grade of fuel must meet the minimum lubricity
requirements that are stated in Refer to Table 25.
• 'BS2869 class A2' off-highway gas oil red diesel
BS2869 can only be used if the sulfur level meets the specifications that are listed in Refer to Table 26.Refer
to Table 27.. An analysis of a sample of fuel must be conducted in order to check the sulfur level.
The use of LSD fuel and the use of ULSD fuel is acceptable provided that the fuels meet the minimum
requirements that are stated in that tables Refer to Table 25.Refer to Table 26.Refer to Table 27.. The lubricity
of these fuels must not exceed wear scar diameter of 0.46mm. The lubricity test must be performed on a HFRR,
operated at 60°C (139.9°F). Refer to 'ISO 12156-1'. By using the test methods 'ASTM D5453, ASTM D2622,
or ISO 20846 ISO 20884', the content of sulfur in LSD fuel must be below 500 PPM (0.05%). By using the
test methods 'ASTM D5453, ASTM D2622,or ISO 20846 ISO 20884', the content of sulfur in ULSD fuel must
be below 15 PPM (0.0015%).
Group 2 Specifications (Permissible Fuels)
The group 2 of fuel specifications is considered acceptable, but these fuels may reduce the engine life and
performance.
• 'ASTM 0975', Grade 10 S15, and Grade 10 S500
• 'JP7 (MIL-T-38219)'
• 'NATO F63'
JP7 and NATO F63 can only be used if the sulfur level meets the specifications that are listed in the Refer to
Table 25., Refer to Table 26.. An analysis of a sample of fuel must be conducted in order to check the sulfur level.
Group 3 Specifications (Aviation Fuels)
The group 3 of fuel specification must be used only with the appropriate fuel additive. This fuel will reduce the
engine life and performance.
