WARNING!
In case of engine runaway due to flammable fumes
from fuel spills or turbocharger oil leaks being
sucked into the engine, do the following to help
avoid personal injury and/or vehicle damage:
1. Turn the ignition switch to the OFF position.
2. Using a CO2 or dry chemical type fire extinguisher,
direct the spray from the fire extinguisher into the
grille on the passenger side so that the spray enters
the engine air intake.
The inlet for the engine air intake is located behind
the passenger side headlamp and receives air
through the grille.
FUEL REQUIREMENTS
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 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 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.

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 im-
portant that you understand and comply with these
requirements. Failure to comply with Oil Change require-
ments 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 ad-
here 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 ofB5. 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 specifi-
cations 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
310 STARTING AND OPERATING
Page 313 of 406

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.
Bio-Diesel Fuel Properties — Low Ambient
Temperatures
Biodiesel fuel may gel or solidify at low ambient tem-
peratures, which may pose problems for both storage and
operation. Precautions can be necessary at low ambienttemperatures, such as storing the fuel in a heated build-
ing 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 PickUp 2500/3500 Only — 15,000 Miles*
• Ram 3500/4500/5500 Chassis Cab — 12,500 Miles*
(*unless otherwise notified with a oil service message)

CAUTION!
•Under no circumstances should oil change inter-
vals 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 intervals 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 se-
vere damage if operated with concentrations of
Biodiesel higher than 20%.

Engine Oil
Checking Oil Level
To assure proper lubrication of your vehicle’s engine, the
engine oil must be maintained at the correct level. Check
the oil level at regular intervals. The best time to check
the oil level is before starting the engine after it has been
parked overnight. When checking oil after operating the
engine, first ensure the engine is at full operating tem-
perature, then wait for 30 minutes after engine shutdown
to check the oil.Checking the oil while the vehicle is on level ground will
improve the accuracy of the oil level readings. Add oil
