ENGINE FLUIDS AND LUBRICANTS
Component Fluid, Lubricant, or Genuine Part
Gas Engine CoolantWe recommend you use Mopar Antifreeze/Coolant 10 Year/150,000 Mile (240,000 km)
Formula OAT (Organic Additive Technology).
Motor Generator Unit – 3.6L Engine (If Equipped) We recommend you use Mopar Antifreeze/Coolant 10 Year/150,000 Mile (240,000 km)
Formula OAT (Organic Additive Technology).
Engine Oil – 3.6L Engine We recommend you use API Certified SAE 0W-20 engine oil, meeting the requirements of FCA
Material Standard MS-6395 such as Mopar, Pennzoil, and Shell Helix. Refer to your engine oil
filler cap for correct SAE grade.
Engine Oil – 5.7L Engine We recommend you use API Certified SAE 5W-20 engine oil, meeting the requirements of FCA
Material Standard MS-6395 such as Mopar, Pennzoil, and Shell Helix. Refer to your engine oil
filler cap for correct SAE grade.
Gas Engine Oil Filter We recommend you use Mopar brand engine oil filters.
Fuel Selection – 3.6L Engine 87 Octane (R+M)/2 Method, 0-15% ethanol (Do not use E-85).
Fuel Selection – 5.7L Engines 89 Octane Recommended - 87 Octane Acceptable (R+M)/2 Method, 0-15% ethanol (Do not
use E-85).
Diesel Engine Coolant We recommend you use 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 you use 5W-40
synthetic engine oil such as Mopar that meets FCA Material
Standard MS-12991 and the API SN engine oil category is required.
Diesel Engine Oil Filter We recommend you use Mopar engine oil filters.
Using an oil filter that does not meet FCA’s
filtration requirements can severely impact engine life and reliability.

476TECHNICAL SPECIFICATIONS
Fuel Filters — 3.0L Turbo Diesel Engine We recommend you use Mopar fuel filter. Must meet 3 micron rating. Using a fuel filter that
does not meet FCA’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.

NOTE:
If Climatized or Number 1 ULSD fuel is not avail -
able, and you are operating below 20°F (-6°C),
in sustained arctic conditions, Mopar Premium
Diesel Fuel Treatment (or equivalent) is recom -
mended to avoid gelling.
CAUTION!
Mixing of engine coolant (antifreeze) other
than specified Organic Additive Technology
(OAT) engine coolant (antifreeze), may
result in engine damage and may decrease
corrosion protection. Organic Additive
Technology (OAT) engine coolant is
different and should not be mixed with
Hybrid Organic Additive Technology (HOAT)
engine coolant (antifreeze) or any “globally
compatible” coolant (antifreeze). If a
non-OAT engine coolant (antifreeze) is
introduced into the cooling system in an
emergency, the cooling system will need to
be drained, flushed, and refilled with fresh
OAT coolant (conforming to MS.90032), by
an authorized dealer as soon as possible.
Do not use water alone or alcohol-based
engine coolant (antifreeze) products. Do
not use additional rust inhibitors or anti-
rust products, as they may not be compat -
ible with the radiator engine coolant and
may plug the radiator.
This vehicle has not been designed for use
with propylene glycol-based engine coolant
(antifreeze). Use of propylene glycol-based
engine coolant (antifreeze) is not recom -
mended.
CAUTION! (Continued)
