Additives
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 must be used as
specified by your fuel supplier who will understand the
concentration level necessary.
– Elf 2S 1750. Dosage 1000-1500 ppm (0.1 - 0.15%),
specifically for Indian Superior Kerosene (SKO) but
may be applicable to other fuels.
– Lubrizol 539N. Dosage (on Swedish low sulphur fuel)
250 ppm.
– Paradyne 7505 (from Infineum). Dosage 500 ppm
(0.05%).
Note: These products are given as examples only. The
information is derived from the manufacturers data. The
products are not recommended or endorsed by JCB.
Service Requirements for use of B20
Biodiesel
– The engine oil must be a grade CH4 as minimum
specification.
– Do not leave unused B20 biodiesel in the fuel tank for
extended periods (top up each day).
– Make sure that 1 in 5 fuel tank fills use standard diesel
to EN590 specification, this will help to prevent
'gumming'.
– Make sure regular oil sampling is completed (look for
excessive unburnt fuel content, water or wear
particles.
– Change the engine oil and filter more frequently (as a
minimum half the recommended intervals), or as
indicated by oil sampling.
– Change the fuel filters more frequently (as a minimum
half the recommended intervals), or if there are
engine performance related issues.
– Make sure the fuel is stored correctly, care must be
taken to make sure no water enters the machine fuel
tank (or the storage tank). Water will encourage
micro-bacterial growth.
– Make sure that the fuel pre-filter is drained daily (not
every week as currently advised).
– Only JCB engines built after Jan. 2007 are applicable
(i.e. engines with 07 on the end of their serial number
and factory filled with CH4 oil) - this is not approved
with other manufacturers.
– Use heater kits in low ambient temperature territories.
– The biodiesel must meet the following standards:
ASTM D6751, DIN 51606, ISO 14214
Note: If necessary use a test kit to confirm the fuel
specification. Testing kits are available (not from JCB
currently), use the internet as a source for the kits.
Note: If performance related issues are to be reported to
JCB Service, and the engine has been run on biodiesel,
then the fuel system must be filled with standard diesel (at
least 2 x tank fills) to EN590 specification and relevant stall
speeds recorded prior to making the report.
Warranty
JCB have shown a commitment to support the
environment by approving the use of biodiesel blended
fuels.
Using a B20 blend of biodiesel requires caution and
additional servicing of the engine is required.

Service
Requirements for use of B20 Biodiesel (
T

Failure to follow the additional recommended service
requirements may lead to a warranty claim being declined.
Failures resulting by the incorrect use of biodiesels or
other fuel additives are not defects of the JCB Dieselmax
engine workmanship and therefore will not be supported
by JCB Warranty.
