TECHNICAL SPECIFICATIONS 417
Diesel fuel is seldom completely free of water.
To prevent fuel system trouble, drain the
accumulated water from the fuel/water
separator filter 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.
Diesel Fuel Specifications
This 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.
NOTE:
If you accidentally fill the fuel tank with gaso-
line on your diesel vehicle, do not start the
engine. Damage to the engine and fuel
system could occur. Please call an autho-
rized 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
necessary for the proper operation of your
diesel engine.
No. 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 specification D975 is recommended for
use with your diesel engine. If frequent
operation with Biodiesel blends that are
between 6% and 7% (B6–B7) is desired, the
maintenance schedule is subject to shorter
intervals.
The oil and filter change along with fuel filter
replacement is subject to shorter intervals when
operating your engine on biodiesel greater than 5%.
Do not use biodiesel greater than 7%.
For regular use of biodiesel blends between 6%
and 7% (B6–B7) it is important that you
understand and comply with these
requirements. Refer to the “Maintenance Plan”
in “Scheduled Servicing” for further direction.
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 between 6% and 7% (B6–B7). There
are no unique restrictions for the use of B5.
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.
CAUTION!
Failure to comply with Oil Change requirements
for vehicles operating on biodiesel blends
between 6% and 7% (B6–B7) will result in prema-
ture engine wear. Such wear is not covered by the
New Vehicle Limited Warranty.
