UEL PECIFICATIONS
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
climatized 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.

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.
TECHNICAL SPECIFICATIONS
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:
Pertrodiesel fuel meeting ASTM specification

D-975 and biodiesel fuel (B100) meeting
ASTM specification D-6751.
