478 TECHNICAL SPECIFICATIONS
A maximum blend of 20% biodiesel meeting
ASTM specification D-7467 may be used with
your Cummins® diesel engine. (Pickup
models configured with B20 Capability.)
In addition, commercially available fuel addi-
tives are not necessary for the proper opera-
tion of your Cummins® diesel engine.
However, if seasonably adjusted fuel is not
available and you are operating below 20°F
(-6°C), Mopar® Premium Diesel Fuel Treat-
ment (or equivalent) may be beneficial to
avoid fuel gelling.
Number 1 Ultra Low Sulfur Diesel Fuel should
only be used where extended arctic condi-
tions (0°F or -18°C) exist.
BIODIESEL FUEL REQUIREMENTS
Pickup Models And Chassis Cab Models
Ordered With B20 Option
Your vehicle has been validated and approved
for the use of biodiesel in blends up to 20%
(B20) provided that you comply with the
requirements outlined below. It is important
that you understand and comply with these
requirements. Failure to comply with Oil Change
requirements for vehicles operating on
biodiesel blends up to B20 will result in
premature engine wear. Such wear is not
covered by the New Vehicle Limited Warranty.
Biodiesel is a fuel produced from renewable
resources typically derived from animal fat,
rapeseed oil (Rapeseed Methyl Ester (RME)
base), or soybean oil (Soy Methyl Ester (SME or
SOME) base). Biodiesel fuel has inherent
limitations which require that you understand
and adhere to the following requirements if you
use blends of biodiesel greater then 5% but not
greater than 20% (B6-B20). There are no
unique restrictions for the use of B5. Use of
blends greater than 20% is not approved. Use of
blends greater than 20% can result in engine
damage. Such damage is not covered by the
New Vehicle Limited Warranty.
Fuel Quality — Must Comply With ASTM
Standards
The quality of biodiesel fuel may vary widely.
Only fuel produced by a BQ9000 supplier to the
following specifications may be blended to
meet biodiesel blend (B6–B20) fuel meeting
ASTM specification D-7467:
Petrodiesel fuel meeting ASTM specification
D-975 and biodiesel fuel (B100) meeting
ASTM specification D-6751.
Fuel Oxidation Stability — Must Use Fuel
Within Six Months Of Manufacture
Biodiesel fuel has poor oxidation stability which
can result in long term storage problems. Fuel
produced to approved ASTM standards, if
stored properly, provides for protection against
fuel oxidation for up to six months.
Fuel Water Separation — Must Use
Mopar®/Cummins® Approved Fuel Filter
Elements
You must use Mopar®/Cummins® approved
fuel filter elements in both your engine mounted
filter and frame mounted filter.
Biodiesel fuel has a natural affinity to water and
water accelerates microbial growth. Your
Mopar®/Cummins® filtration system is
designed to provide adequate fuel water
separation capabilities.
