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 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
necessary 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
specification D975 is recommended for use with
your diesel engine. If frequent operation with
Biodiesel blends that are between 6% and 20%
(B6–B20) 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 20%. For regular use of biodiesel blends between 6%
and 20% (B6–B20) it is important that you
understand and comply with these requirements.
For further direction Ú
page 402.
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 20% (B6–B20). 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
Ú page 412.
CAUTION!
Failure to comply with Oil Change requirements
for vehicles operating on biodiesel blends
between 6% and 20% (B6–B20) will result in
premature engine wear. Such wear is not
covered by the New Vehicle Limited Warranty.
CAUTION!
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.

Component Fluid, Lubricant, or Genuine Part
Diesel Engine CoolantWe recommend using Mopar® Antifreeze/Coolant 10 Year/150,000 Mile (240,000 km) Formula OAT (Organic Additive
Technology).
Engine Oil — 3.0L Turbo
Diesel Engine We recommend using 5W-40
synthetic engine oil such as Mopar® that meets the manufacturer Material Standard MS-12991
and the API SP engine oil category is required.
Diesel Engine Oil Filter We recommend using Mopar® engine oil filters.
Using an oil filter that does not meet the manufacturer’s filtration
requirements can severely impact engine life and reliability.
Fuel Filters — 3.0L Turbo
Diesel Engine We recommend using Mopar® fuel filter. Must meet 3 micron rating.
Using a fuel filter that does not meet the manufacturer’s
filtration and water separating requirements can severely impact fuel system life and reliability. Under normal conditions the
diesel fuel filter should be replaced every 20,000 miles (32,000 km) (every other oil change). If the vehicle is being used in
severe operating conditions, or In certain geographical areas of the country (Pennsylvania, New York, Ohio, Maryland, West
Virginia, Arkansas, Oklahoma, Kansas, Iowa, Missouri and Nebraska) due to fuel cleanliness issues, it’s recommended to
replace the fuel filter every 10,000 miles (16,000 km).
Fuel Selection — 3.0L Turbo
Diesel Engine Use good quality diesel fuel from a reputable supplier in your vehicle. Federal law requires that you must fuel this vehicle with
Ultra Low Sulfur Highway Diesel fuel (15 ppm Sulfur maximum) and prohibits the use of Low Sulfur Highway Diesel fuel (500
ppm Sulfur maximum) to avoid damage to the emissions control system.
For most year-round service, Number 2 diesel fuel meeting ASTM specification D-975 Grade S15 will provide good
performance. We recommend you use a blend of up to 5% biodiesel, meeting ASTM specification D-975 with your diesel engine.
This vehicle is compatible with biodiesel blends greater than 5% but no greater than 20% biodiesel meeting ASTM specification
D-7467 provided the shortened maintenance intervals are followed as directed.
Diesel Exhaust Fluid Mopar® Diesel Exhaust Fluid (API Certified) (DEF) or equivalent that has been API Certified to the ISO 22241 standard. Use of
fluids not API Certified to ISO 22241 may result in system damage.
