Fuel Specifications
The Cummins Turbocharged, Charge Air Cooled, 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: A maximum blend of 5% biodiesel meeting
ASTM specification D-6751 may be used with your
Cummins Diesel equipped vehicle.
NOTE: In addition, commercially available fuel addi-
tives are not necessary for the proper operation of your
Cummins Diesel equipped vehicle.
NOTE: No. 1 Ultra Low Sulfur diesel fuel should only
be used where extended arctic conditions (-10°F or -23°C)
exist.
ADDING FUEL (DIESEL ENGINES)
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 gas cap until you hear a “clicking” sound.
This is an indication that the gas cap is properly
tightened.
•
Make sure that the gas cap is tightened each time the
vehicle is refueled.
