72 TECHNICAL SPECIFICATIONS
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 between 6% and 20%
(B6–B20). There are no unique restrictions for the use of B5.
CAUTION!
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.
Biodiesel Fuel Properties — Low Ambient
Temperatures
Biodiesel fuel may gel or solidify at low ambient tempera-
tures, which may pose problems for both storage and
operation. Precautions can be necessary at low ambient
temperatures, such as storing the fuel in a heated building
or a heated storage tank, or using cold temperature addi-
tives.
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 specifica-
tions 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 protec-
tion against fuel oxidation for up to six months.
Fuel Water Separation — Must Use Mopar Approved
Fuel Filter Elements
Biodiesel fuel has a natural affinity to water and water
accelerates microbial growth. Your Mopar filtration system
is designed to provide adequate fuel water separation
capabilities.
