TECHNICAL SPECIFICATIONS 367
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.
Bio-Diesel Fuel Properties — Low Ambient
Temperatures
Biodiesel fuel may gel or solidify at low ambient
temperatures, 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
additives.
Fuel In Oil Dilution — Must Adhere To
Required Oil Change Interval
Fuel dilution of lubricating oil has been
observed with the use of biodiesel fuel. Fuel in
oil must not exceed 5%. To ensure this limit is
met your oil change interval must be
maintained to the following schedule:
Ram 3500/4500/5500 Chassis Cab —
12,500 Miles (20,000 km)*
(*unless otherwise notified with a oil service
message)
CAUTION!
Under no circumstances should oil change
intervals exceed 12,500 miles (20,000 km)
if operation occurs with greater than 5%
biodiesel blends. Oil change intervals should
not exceed 6 months in either case. Failure
to comply with these Oil Change require-
ments for vehicles operating on biodiesel
blends up to B20 may result in premature
engine wear. Such wear is not covered by
the New Vehicle Limited Warranty.
B20 Biodiesel capable: The engine may
suffer severe damage if operated with
concentrations of Biodiesel higher than
20%.
