TECHNICAL SPECIFICATIONS447
Problems that result from using gasoline
containing more than 15% ethanol (E-15) or
gasoline containing methanol are not the
responsibility of the manufacturer and may void
or not be covered under New Vehicle Limited
Warranty.
Do Not Use E-85 In Non-Flex Fuel Vehicles
Non-Flex Fuel Vehicles (FFV) are compatible
with gasoline containing up to 15% ethanol
(E-15). Use of gasoline with higher ethanol
content may void the New Vehicle Limited
Warranty.
If a Non-FFV vehicle is inadvertently fueled with
E-85 fuel, the engine will have some or all of
these symptoms:
Operate in a lean mode.
OBD II Malfunction Indicator Light on.
Poor engine performance.
Poor cold start and cold drivability.
Increased risk for fuel system component
corrosion.
CNG And LP Fuel System Modifications
Modifications that allow the engine to run on
Compressed Natural Gas (CNG) or Liquid
Propane (LP) may result in damage to the
engine, emissions, and fuel system compo -
nents. Problems that result from running CNG
or LP are not the responsibility of the manufac -
turer and may void or not be covered under the
New Vehicle Limited Warranty.
MMT In Gasoline
Methylcyclopentadienyl Manganese Tricarbonyl
(MMT) is a manganese-containing metallic addi -
tive that is blended into some gasoline to
increase octane. Gasoline blended with MMT
provides no performance advantage beyond
gasoline of the same octane number without
MMT. Gasoline blended with MMT reduces
spark plug life and reduces emissions system
performance in some vehicles. The manufac -
turer recommends that gasoline without MMT
be used in your vehicle. The MMT content of
gasoline may not be indicated on the gasoline
pump; therefore, you should ask your gasoline
retailer whether the gasoline contains MMT.
MMT is prohibited in Federal and California
reformulated gasoline.
Fuel System Cautions
CAUTION!
Follow these guidelines to maintain your
vehicle’s performance:
The use of leaded gasoline is prohibited by
Federal law. Using leaded gasoline can
impair engine performance and damage
the emissions control system.
An out-of-tune engine or certain fuel or igni -
tion malfunctions can cause the catalytic
converter to overheat. If you notice a
pungent burning odor or some light smoke,
your engine may be out of tune or malfunc -
tioning and may require immediate service.
Contact an authorized dealer for service
assistance.
The use of fuel additives, which are now
being sold as octane enhancers, is not
recommended. Most of these products
contain high concentrations of methanol.
Fuel system damage or vehicle perfor -
mance problems resulting from the use of
such fuels or additives is not the responsi -
bility of the manufacturer and may void or
not be covered under the New Vehicle
Limited Warranty.8

NOTE:
Intentional tampering with the emissions
control system can result in civil penalties being
assessed against you.
Carbon Monoxide Warnings
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.
WARNING!
Carbon monoxide (CO) in exhaust gases is
deadly. Follow the precautions below to
prevent carbon monoxide poisoning:
Do not inhale exhaust gases. They contain
carbon monoxide, a colorless and odorless
gas, which can kill. Never run the engine in
a closed area, such as a garage, and never
sit in a parked vehicle with the engine
running for an extended period. If the
vehicle is stopped in an open area with the
engine running for more than a short
period, adjust the ventilation system to
force fresh, outside air into the vehicle.
Guard against carbon monoxide with
proper maintenance. Have the exhaust
system inspected every time the vehicle is
raised. Have any abnormal conditions
repaired promptly. Until repaired, drive with
all side windows fully open.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.

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.
Biodiesel Fuel Requirements
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.
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 main -
tained to the following schedule:
Ram PickUp 2500/3500 Only — 15,000 Miles*
(*unless otherwise notified with a oil service
message)
CAUTION!
Under no circumstances should oil change
intervals exceed 15,000 miles (24 000 km)
pickup or 12,500 miles (20 000 km)
chassis cab if operation occurs with greater
than 5% biodiesel blends. Oil change inter -
vals should not exceed 6 months in either
case. Failure to comply with these Oil
Change requirements 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%.
