402TECHNICAL SPECIFICATIONS
FUEL REQUIREMENTS – DIESEL ENGINE
Use good quality diesel fuel from a reputable
supplier in your vehicle. Federal law requires
that you must fuel this vehicle with Ultra Low
Sulfur Highway Diesel fuel (15 ppm Sulfur
maximum) and prohibits the use of Low Sulfur
Highway Diesel fuel (500 ppm Sulfur maximum)
to avoid damage to the emissions control
system.
For most year-round service, No. 2 diesel fuel
meeting ASTM (formerly known as the American
Society for Testing and Materials) specification
D-975 Grade S15 will provide good perfor -
mance. If the vehicle is exposed to extreme cold
(below 20°F or -7°C), or is required to operate
at colder-than-normal conditions for prolonged
periods, use climatized No. 2 diesel fuel or
dilute the No. 2 diesel fuel with 50% No. 1 diesel
fuel. This will provide better protection from fuel
gelling or wax-plugging of the fuel filters. Diesel fuel is seldom completely free of water.
To prevent fuel system trouble, drain the accu
-
mulated water from the fuel/water separator
using the fuel/water separator drain provided
on both fuel filters. If you buy good quality fuel
and follow the cold weather advice above, fuel
conditioners should not be required in your
vehicle. If available in your area, a high cetane
“premium” diesel fuel may offer improved
cold-starting and warm-up performance.
Fuel Specifications
The Cummins® Turbo Diesel engine has been
developed to take advantage of the high energy
content and generally lower cost No. 2 Ultra Low
Sulfur diesel fuel or No. 2 Ultra Low Sulfur clima-
tized diesel fuels. Experience has shown that it
also operates on No. 1 Ultra Low Sulfur diesel
fuels or other fuels within specification. NOTE:
If you accidentally fill the fuel tank with gaso
-
line on your diesel vehicle, Do not start the
vehicle. If you restart your vehicle you risk
damaging the engine and fuel system. Please
call an authorized 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 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.
No. 1 Ultra Low Sulfur diesel fuel should only
be used where extended arctic conditions
(0°F or -18°C) exist.
WARNING!
Do not use alcohol or gasoline as a fuel
blending agent. They can be unstable under
certain conditions and hazardous or
explosive when mixed with diesel fuel.
CAUTION!
If the “Water in Fuel Indicator Light” remains
on, DO NOT START engine before you drain
the water from the fuel filter(s) to avoid
engine damage. Refer to “Draining Fuel/
Water Separator Filter” in “Servicing And
Maintenance” for further information.

TECHNICAL SPECIFICATIONS403
Biodiesel Fuel Requirements
Chassis Cab Models
A maximum blend of 5% biodiesel meeting
ASTM specification 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 require -
ments outlined below. It is important 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 prema -
ture 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 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:
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 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 capa-
bilities.
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.
