Use good quality diesel fuel to get the correct power and
performance from your engine.
Recommended Fuel Specification
– EN590 Diesel Fuel Types - Auto/Co/C1/C2/C3/C4.
– BS2869 Class A2.
– ASTM D975-91 Class 2-2DA, US DF1, US DF2, US
DFA.
– JIS K2204 (1992) Grades 1, 2, 3, and Special Grade
3.
Note: Where low sulphur/low aromatic fuels are used it is
important that lubricity additives are used. The additives
listed below are advertised as being suitable for bringing
the lubricity levels of kerosene/low sulphur fuels up to
those of diesel fuels. They have not been tested or
approved by the engine manufacturer. They should be
added by your fuel supplier who should understand the
concentration level necessary.
1 Elf 2S 1750. Dosage 1000-1500 ppm (0.1 - 0.15%),
specifically for Indian Superior Kerosene (SKO) but
may be applicable to other fuels.
2 Lubrizol 539N. Dosage (on Swedish low sulphur fuel)
250 ppm.
3 Paradyne 7505 (from Infineum). Dosage 500 ppm
(0.05%).
!MCAUTION
Consult your fuel supplier or JCB distributor about the
suitability of any fuel you are unsure of.
GEN-9-2
Acceptable Fuel Specification
!MCAUTION
The fuel specification below is acceptable, however
this fuel may reduce the life of the fuel injection
equipment. The use of this fuel may also affect the
engine performance.
GEN-9-3
– ASTM D975-91 Class 1-1DA.
– JP7, MIL T38219 XF63.
– NATO F63.
Sulphur Content
!MCAUTION
A combination of water and sulphur will have a
corrosive chemical effect on fuel injection equipment.
It is essential that water is eradicated from the fuel
system when high sulphur fuels are used.
ENG-3-2
High sulphur content can cause engine wear. (High
sulphur fuel is not normally found in North America,
Europe or Australia.) If you have to use high sulphur fuel
you must change the engine oil more frequently.

Aviation Kerosene Fuels
Note: Aviation kerosene fuels are not approved and their
use may cause damage to components. Warranty will not
be allowed on any component where damage is found to
have been caused by the use of aviation kerosene.
Low Temperature Fuels
Special winter fuels may be available for engine operation
at temperatures below 0°C (32°F). These fuels have a
lower viscosity. They also limit wax formation in the fuel at
low temperatures. (Wax forming in the fuel can stop the
fuel flowing through the filter.)
