approved biodiesel fuels or other fuel
additives that 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.
PACCAR recommends that customers
intending to use biodiesel blends become
familiar with the additional handling
considerations of these fuels such as
aging, metal compatibility and tendency to
absorb water. Please reference the fuel
supplier’s technical information or industry
guidelines such as the American Trucking
Association Truck Maintenance Council
document RP 357.
In particular, operators should be aware
that biodiesel blends are more prone to
cold flow (gelling) and filter plugging issues
compared to conventional diesel fuel. If
vehicles are expected to be operated in
temperatures below freezing, care should
be taken to ensure that both the biodiesel
fuel used and the appropriate vehicle fuel
system accessory heaters are utilized.
Operators should also be aware that
biodiesel energy content (by volume) is
lower than diesel which can reduce fuel
economy by up to two percent.
Recommendations to
Avoid Fuel Gelling
To avoid fuel gelling in cold weather:
•
Use appropriate fuel grade/blend
for conditions
•
Spec your vehicle with proper cold
weather equipment (12V electric
pre-heater, fuel/coolant heater, 12V
fuel line heaters and fuel tank
heaters)
PACCAR does not recommend the use of
fuel additives, however, should a customer
decide there is a need for temporary use of
a winter fuel additive, PACCAR offers the
following guidance:
•
Use an industry known, high quality
product (EPA-approved)
•
Check the product label to ensure it
is compatible with ultra-low sulfur
diesel fuel and aftertreatment
systems
•
Only use the additive for the
minimum time needed
•
Follow the additive manufacturer's
instructions exactly
