WARNING!
Do not use alcohol or gasoline as a fuel blending
agent. They can be unstable under certain conditions
and hazardous or explosive when mixed with diesel
fuel.
Diesel fuel is seldom completely free of water. To pre-
vent fuel system trouble, drain the accumulated water
from the fuel/water separator using the fuel/water
separator drain provided on the fuel filter housing. If
you buy good quality fuel and follow the cold weather
advice above, fuel conditioners should not be required
in your vehicle. If available in your area, a high cetane
“premium” diesel fuel may offer improved cold-starting
and warm-up performance.
CAUTION!
If the “Water in Fuel Indicator Light” remains on, DO
NOT START engine before you drain the water from
the fuel filter(s) to avoid engine damage. Refer to
“Draining Fuel/Water Separator Filter” in “Servicing
And Maintenance” for further information.
DIESEL FUEL SPECIFICATIONS
This diesel engine has been developed to take advan-
tage of the high energy content and generally lower cost
Number 2 Ultra Low Sulfur diesel fuel or Number
2 Ultra Low Sulfur climatized diesel fuels.
NOTE:
•
If you accidentally fill the fuel tank with gasoline or
DEF on your diesel vehicle, do not start the engine.
Damage to the engine and fuel system could occur.
Please call an authorized dealer for service.
•
A maximum blend of 5% biodiesel meeting ASTM
specification D-975 may be used with your diesel
engine without any adjustments to regular service
schedules.
•
Commercially available fuel additives are not neces-
sary for the proper operation of your diesel engine.
•
Number 1 Ultra Low Sulfur diesel fuel should only
be used where extended arctic conditions (-10°F or
-23°C) exist.
BIODIESEL FUEL REQUIREMENTS
A maximum blend of 5% biodiesel meeting ASTM speci-
fication D975 is approved for use with your diesel
engine.
Biodiesel is a fuel produced from renewable resources
typically derived from animal fat, rapeseed oil (Rape-
seed Methyl Ester (RME) base), or soybean oil (Soy
Methyl Ester (SME or SOME) base).
CAUTION!
In the event that the vehicle is filled with fuel contain-
ing greater than 5% biodiesel (B6-B20), the fuel must
be used within 30 days by driving (to less than a quar-
ter tank) and filled with fresh diesel fuel. Failure to do
so can result in engine damage that is not covered by
the New Vehicle Limited Warranty.
