Bio-Diesel Fuel Properties - Dodge RAM 1500 2018 Diesel Supplement

212 TECHNICAL SPECIFICATIONS
(SME or SOME) base). Biodiesel fuel has inherent limita-
tions 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 specifica-
tions may be blended to meet biodiesel blend (B6–B20) fuel
meeting ASTM specification D-7467:
• Pretrodiesel 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/Cummins
Approved Fuel Filter Elements
You must use Mopar/Cummins approved fuel filter ele-
ments 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 filtra-
tion system is designed to provide adequate fuel water
separation capabilities.
Bio-Diesel Fuel Properties — Low Ambient
Temperatures
Biodiesel fuel may gel or solidify at low ambient tempera-
tures, which may pose problems for both storage and opera-
tion. Precautions can be necessary at low ambient tempera-
tures, such as storing the fuel in a heated building or a heated
storage tank, or using cold temperature additives.
