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
NOTE:
Intentional tampering with the emissions
control system can result in civil penalties being
assessed against you.
Carbon Monoxide Warnings
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.
CAUTION! (Continued)
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.

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.

SUGGESTIONS FOR OBTAINING SERVICE
FOR YOUR VEHICLE
Prepare For The Appointment
If you are having warranty work done, be sure to
have the right papers with you. Take your
warranty folder. All work to be performed may
not be covered by the warranty. Discuss addi -
tional charges with the service manager. Keep a
maintenance log of your vehicle's service
history. This can often provide a clue to the
current problem.
Prepare A List
Make a written list of your vehicle's problems or
the specific work you want done. If you've had
an accident or work done that is not on your
maintenance log, let the service advisor know.
Be Reasonable With Requests
If you list a number of items and you must have
your vehicle by the end of the day, discuss the
situation with the service advisor and list the
items in order of priority. At many authorized
dealers, you may obtain a rental vehicle at a
minimal daily charge. If you need a rental, it is
advisable to make these arrangements when
you call for an appointment.
IF YOU NEED ASSISTANCE
The manufacturer and its authorized dealers
are vitally interested in your satisfaction. We
want you to be happy with our products and
services.
Warranty service must be done by an autho -
rized dealer. We strongly recommend that you
take the vehicle to an authorized dealer. They
know your vehicle the best, and are most
concerned that you get prompt and high quality
service. The manufacturer's authorized dealers
have the facilities, factory-trained technicians,
special tools, and the latest information to
ensure the vehicle is fixed correctly and in a
timely manner. This is why you should always talk to an autho
-
rized dealer service manager first. Most matters
can be resolved with this process.
If for some reason you are still not satisfied,
talk to the general manager or owner of the
authorized dealer. They want to know if you
need assistance.
If an authorized dealer is unable to resolve
the concern, you may contact the manufac -
turer's customer center.
Any communication to the manufacturer's
customer center should include the following
information:
Owner's name and address
Owner's telephone number (home, mobile,
and office)
Authorized dealer name
Vehicle Identification Number (VIN)
Vehicle delivery date and mileage
