TECHNICAL SPECIFICATIONS437

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 Treatment (or equivalent)
may be beneficial to avoid fuel gelling.

Number 1 Ultra Low Sulfur diesel fuel should
only be used where extended arctic condi -
tions (0°F or -18°C) exist.
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
requirements outlined below. It is important
that you understand and comply with these
requirements. 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
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.

442TECHNICAL SPECIFICATIONS
Fuel Selection 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 specification D-975 Grade
S15 will provide good performance.
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).
