operation at low ambient temperatures, it is
important to specify diesel fuel of the
correct cetane number.
PACCAR requires all permissible fuels to
have adequate fuel lubricity. Lubricity can
be determined by ASTM, specification
D6079, ISO 12156, High Frequency
Reciprocating Rig (HFRR) in which the fuel
must have a wear scar diameter of 0.02 in.
(0.5 mm) or less.
The use of Ultra-low-sulfur diesel (ULSD)
fuel is required for this engine in order to
meet emission regulations and to prevent
damage to the engine and exhaust system.
The use of other grades of diesel fuels
other than ULSD fuel will be considered a
use of incorrect fuel for the engine.
PACCAR is not responsible for failures
caused by the use of incorrect fuel, oil or
DEF or by water, dirt or other contaminants
in the fuel or DEF.
Warranty and the Use of
Renewable and Other
Paraffinic Diesel Fuels
PACCAR Inc. approves the use of
paraffinic diesel at any blend level or as a
stand-alone fuel, providing that the
following conditions are met:
•
The paraffinic diesel in the fuel
meets EN 15940 specifications,
and
•
The finished fuel meets the
properties of ASTM Standard D975
The use of approved paraffinic diesel fuel
does not affect the PACCAR engine
warranty, or its maintenance intervals.
Failures caused by the use of fuels that are
not approved, are of unacceptable quality,
or do not meet specified industry standards
are not considered as defects of parts or
workmanship by PACCAR and therefore
will not be covered by the PACCAR engine
warranty. Specifically, raw or unprocessed
vegetable oils differ heavily from paraffinic
diesel and are not approved.
PACCAR recommends that customers
intending to use paraffinic diesel become
familiar with the properties of these fuels.
Please reference the fuel supplier’s
technical information and request a copy of
the certificate of analysis if it is unclear
whether the fuel meets specifications. In
particular, operators should be aware that
paraffinic fuels are more prone to cold flow
(gelling) and filter plugging issues if not
formulated to meet climate-dependent
requirements for the region. Operators
should also be aware that paraffinic diesel
energy content (by volume) is lower than
that of petroleum diesel, which can reduce
fuel economy by up to four percent as a
stand-alone fuel.
Warranty and the Use of
Biodiesel Fuel
PACCAR Inc. approves the use of
biodiesel fuel blends up to 20 percent by
volume in diesel fuel providing that the
following conditions are met:
•
The biodiesel used in the blend
meets ASTM Standard D6751 or
EN 14214 specifications.
•
The biodiesel used in the blend is
sourced from a BQ-9000
Accredited Producer.
•
The finished blend meets the fuel
properties of the ASTM Standard
D975 (up to B5 blend) or D7467
(B6 to B20 blend).
•
If using B6-B20 the engine oil and
oil filter are changed per the
modified schedule. See the
Preventative Maintenance
Schedule.
•
If using B6-B20 the fuel filter is
changed every 25,000 miles
(40,000 km).
