•Commercially available fuel additives are not necessary
for the proper operation of your diesel engine.
• No. 1 Ultra Low Sulfur diesel fuel should only be used
where extended arctic conditions (-10°F or -23°C) exist.
Biodiesel Fuel Requirements
A maximum blend of 5% biodiesel meeting ASTM specifi-
cation D975 is recommended for use with your diesel
engine. If frequent operation with biodiesel blends that are
between 6% and 20% (B6–B20) is desired, the maintenance
schedule is subject to shorter intervals.
The oil and filter change along with fuel filter replacement
is subject to shorter intervals when operating your engine
on biodiesel greater than 5%. Do not use biodiesel greater
than 20%.
For regular use of biodiesel blends between 6% and 20%
(B6–B20) it is important that you understand and comply
with these requirements. Refer to the “Maintenance Chart”
in the “Maintenance Schedules” section for further direc-
tion.
CAUTION!
Failure to comply with Oil Change requirements for
vehicles operating on biodiesel blends between 6%
and 20% (B6–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 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.

into the atmosphere. The durability of your engine and
life expectancy of this diesel particulate filter emission
device is highly dependent on the use of the correct
engine oil.
We recommend you use 5W-40 syntheticengine oil such as
MOPAR or Shell Rotella that meets FCA Material Standard
MS-10902 and the API CJ-4 engine oil category is required.
Materials Added To Engine Oil
The manufacturer strongly recommends against the addi-
tion of any additives (other than leak detection dyes) to the
engine oil. Engine oil is an engineered product and its
performance may be impaired by supplemental additives.
Engine Oil Filter
Refer to “Fluids, Lubricants, And Genuine Parts” in “Main-
taining Your Vehicle” for further information. The engine
oil filter should be changed at every engine oil change.
Disposing Of Used Engine Oil And Oil Filters
Care should be taken in disposing of used engine oil and
oil filters from your vehicle. Used oil and oil filters,
indiscriminately discarded, can present a problem to the environment. Contact your authorized dealer, service sta-
tion or governmental agency for advice on how and where
used oil and oil filters can be safely discarded in your area.
Engine Air Cleaner Filter
WARNING!
The air induction system (air cleaner, hoses, etc.) pro-
vides a measure of protection. Do not remove the air
induction system (air cleaner, hoses, etc.) unless such
removal is necessary for repair or maintenance. Make
sure that no one is near the engine compartment before
starting the vehicle with the air induction system (air
cleaner, hoses, etc.) removed. Failure to do so can result
in serious personal injury.
CAUTION!
All air entering the engine intake must be filtered. The
abrasive particles in unfiltered air will cause rapid
wear to engine components.
Refer to the “Maintenance Schedule” for the proper main-
tenance intervals.

NOTE:
•If you accidentally fill the fuel tank with gasoline on
your diesel vehicle, Do not start the vehicle. If you
restart your vehicle you risk damaging the engine and
fuel system. Please call your local dealer for service.
• A maximum blend of 5% biodiesel meeting ASTM
specification D-975 may be used with your Cummins
diesel engine. (Chassis Cab models not configured with
B20 capability.)
• A maximum blend of 20% biodiesel meeting ASTM
specification D-7467 may be used with your Cummins
diesel engine. (Pickup models and Chassis Cab models
configured with B20 Capability.)
• In addition, commercially available fuel additives are
not necessary for the proper operation 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 Treatment (or equivalent)
may be beneficial to avoid fuel gelling.

Chassis Cab Models
A maximum blend of 5% biodiesel meeting ASTM specifi-
cation D975 may be used with your Cummins diesel
engine. If operation with biodiesel blends greater than 5%
but not greater than 20% (B6-B20) is desired, the truck must
first be reconfigured by an authorized Ram dealer and the
provisions in the following section must be adhered to.
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 impor-
tant that you understand and comply with these require-
ments. 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 limita-
tions which require that you understand and adhere to the
158 STARTING AND OPERATING
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
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 fil-
tration 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.
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:

Engine oil not designated by the FCA or Cummins Material
Standards and API CJ-4 should not be used, as engine and
exhaust system durability may be compromised. The en-
gine oil filler cap also shows the recommended engine oil
viscosity for your engine. For information on engine oil
filler cap location, refer to “Engine Compartment” in
“Maintaining Your Vehicle” for further information.
Synthetic Engine Oils
You may use synthetic engine oils if the recommended oil
quality requirements are met and the recommended main-
tenance intervals for oil and filter changes are followed.
