Fuel Specifications
The Cumminsdiesel 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:
•A maximum blend of 5% biodiesel meeting ASTM
specification D-6751 may be used with your Cum-
mins diesel engine.
•In addition, commercially available fuel additives are
not necessary for the proper operation of your Cum-
minsdiesel engine.
•No. 1 Ultra Low Sulfur diesel fuel should only be used
where extended arctic conditions (-10°F or -23°C) exist.
ADDING FUEL
CAUTION!
To avoid fuel spillage and overfilling, do not “top
off” the fuel tank after filling.
NOTE:
•When the fuel nozzle “clicks” or shuts off, the fuel
tank is full.
•Tighten the fuel filler cap until you hear a “clicking”
sound. This is an indication that the fuel filler cap is
properly tightened.
•Make sure that the fuel filler cap is tightened each time
the vehicle is refueled.

STARTING AND OPERATING 83
CAUTION!
Due to lack of lubricants in alcohol or gasoline, the
use of these fuels can cause damage to the fuel
system.
NOTE:
•A maximum blend of 5% biodiesel, meeting ASTM
specification D-6751 may be used with your Cum-
mins diesel engine. Use of biodiesel mixture in excess
of 5% can negatively impact the fuel filter’s ability to
separate water from the fuel, resulting in high pressure
fuel system corrosion or damage.
•Ethanol blends are not recommended or approved for
use with your Cummins diesel engine.
•In addition, commercially available fuel additives are
not necessary for the proper operation of your Cum-
minsdiesel engine.
Intervention Regeneration Strategy – EVIC
Message Process Flow
The Cummins diesel engine meets all EPA Heavy Duty
Diesel Engine Emissions Standards, resulting in the low-
est emitting diesel engine ever produced.
To achieve these emissions standards, your vehicle is
equipped with a state-of-the-art engine and exhaust
system. The engine and exhaust after-treatment system
work together to achieve the EPA Heavy Duty Diesel
Engine Emissions Standards. These systems are seam-
lessly integrated into your vehicle and managed by the
Cummins Powertrain Control Module (PCM). The PCM
manages engine combustion to allow the exhaust sys-
tem’s catalyst to trap and burn Particulate Matter (PM)
pollutants, with no input or interaction on your part.
Additionally, your vehicle has the ability to alert you to
additional maintenance required on your truck or engine.
