TECHNICAL SPECIFICATIONS401
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, Number 2 diesel fuel
meeting ASTM (formerly known as the American
Society for Testing and Materials) specification
D-975 Grade S15 will provide good performance. 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 Number 2 diesel fuel or
dilute the Number 2 diesel fuel with 50% Number
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
accumulated 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 Number 2 Ultra
Low Sulfur diesel fuel or Number 2 Ultra Low Sulfur
climatized diesel fuels. Experience has shown that
it also operates on Number 1 Ultra Low Sulfur
diesel fuels or other fuels within specification.
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 an autho-
rized dealer for service.
A maximum blend of 20% biodiesel meeting
ASTM specification D-7467 may be used with
your Cummins® diesel engine. (Models config
-
ured with B20 Capability.)
In addition, commercially available fuel addi -
tives 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.
Number 1 Ultra Low Sulfur diesel fuel should
only be used where extended arctic conditions
(0°F or -18°C) exist.
BIODIESEL FUEL REQUIREMENTS
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 important that you understand
and comply with these requirements. Failure to
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

402TECHNICAL SPECIFICATIONS
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 limitations 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:
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.
Biodiesel 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 six 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 concentra -
tions of Biodiesel higher than 20%.

If climatized or diesel Number 1 ULSD fuel is not available, and you are
operating below (20°F/-6°C), in sustained arctic conditions, Mopar® Premium
Diesel Fuel Treatment (or equivalent) is recommended to avoid gelling.

This vehicle is fully compatible with biodiesel blends up to 5% biodiesel
meeting ASTM specification D-975.
Pickup models, and Chassis Cab models
configured with optional B20 capability, are additionally compatible with 20%
biodiesel meeting ASTM specification D-7467.
Diesel Exhaust Fluid Mopar® Diesel Exhaust Fluid (API Certified) (DEF) or equivalent that has been
API Certified to the ISO 22241 standard. Use of fluids not API Certified to ISO
22241 may result in system damage. You can receive assistance in locating
DEF in the United States by calling 866-RAM-INFO (866-726-4636). In Canada
call 1–800–465–2001 (English) or 1–800–387–9983 (French).

CAUTION!
Mixing of engine coolant (antifreeze) other than specified Organic Additive Technology (OAT) engine coolant (antifreeze), may result in engine damage and
may decrease corrosion protection. Organic Additive Technology (OAT) engine coolant is different and should not be mixed with Hybrid Organic Additive Tech -
nology (HOAT) engine coolant (antifreeze) or any “globally compatible” coolant (antifreeze). If a non-OAT engine coolant (antifreeze) is introduced into the
cooling system in an emergency, the cooling system will need to be drained, flushed, and refilled with fresh OAT coolant (conforming to MS.90032), by an
authorized dealer as soon as possible.
