2018 JEEP WRANGLER UNLIMITED Owner handbook (in English)

FUEL REQUIREMENTS —
DIESEL ENGINE
Use good quality diesel fuel from a reputable
supplier. If the outside temperature is very
low, the diesel fuel thickens due to the for-
mation of paraffin clots with consequent de-
fective operation of the fuel supply system.
In order to avoid these problems different
types of fuel are distributed according to the
season: summer type, winter type and arctic
type (cold/mountain areas). If fueling with
diesel fuel whose features are not suitable for
the temperature of use, it is advisable to mix
in a suitable additive with the fuel. With the
proportions shown on the container, pour the
additive in the tank before fueling.
When using or parking the vehicle for a long
time in the mountains or cold areas, it isadvisable to refuel using locally available
fuel. In this case, it is also advisable to keep
the tank over half full.
This vehicle must only use premium diesel
fuel that meets the requirements of EN 590.
Biodiesel blends up to 7% that meet EN
590 may also be used.
WARNING!
Do not use alcohol or gasoline as a fuel-
blending agent. They can be unstable un-
der certain conditions and hazardous or
explosive when mixed with diesel fuel.
CAUTION!
The manufacturer requires that you must
fuel this vehicle with Ultra Low Sulfur
CAUTION!
Highway Diesel fuel (15 ppm Sulfur maxi-
mum) and prohibits the use of Low Sulfur
Highway Diesel fuel.
Diesel fuel is seldom completely free of wa-
ter. To prevent fuel system trouble, drain the
accumulated water from the fuel/water sepa-
rator using the provided fuel/water separator
drain. If you buy good quality fuel and follow
the cold weather advice above, fuel condi-
tioners should not be required in your vehicle.
If available in your area, a high cetane “pre-
mium” diesel fuel may offer improved cold-
starting and warm-up performance.

Fuel Icon Identification Compliant To
EN16942
The following symbols make it easier to rec-
ognize the correct type of fuel to be used on
your vehicle. Before proceeding with the sup-ply, check the symbols placed inside the fuel
filler flap (if present) and compare them with
the symbol on the fuel pump (if present).

FLUIDS AND LUBRICANTS
Engine
Your vehicle is equipped with an engine oil
that has been thoroughly developed and
tested in order to meet the requirements ofthe Scheduled Servicing Plan. Constant use
of the prescribed lubricants guarantees the
fuel consumption and emission specifica-
tions. Lubricant quality is crucial for engine
operation and duration. If lubricants con-
forming to the specific request are not avail-
able, products that meet the indicated speci-fications can be used to top up, in this case
optimal performance of the engine is not
guaranteed.
Component Fluid, Lubricant, or Genuine Part
Engine Coolant We recommend you use PARAFLUUPFormula OAT (Organic Additive Technology) or
equivalent meeting the requirements of FCA Material Standard MS.90032.
Intercooler – If Equipped We recommend you use PARAFLU
UPFormula OAT (Organic Additive Technology) or
equivalent meeting the requirements of FCA Material Standard MS.90032.
Engine Oil — 2.0L Gasoline Engine We recommend you use API SN PLUS Certified SAE 5W-30 Full Synthetic Engine Oil which
meets the requirements of FCA Material Standard MS-13340. If SN PLUS or equivalent oil
is unavailable then use SAE 0W-30 ACEA C2/API SN Full Synthetic Engine Oil which meets
the requirement of FCA Material Standard 9.55535-GS1, such as SELENIA DIGITEK.
CAUTION!
Failure to use the recommended SN PLUS or equivalent oil can cause engine damage not cov-
ered by the vehicle warranty.
Engine Oil — 3.6L Gasoline Engine We recommend you use, API Certified SAE 0W-20 Engine Oil, meeting the requirements
of FCA Material Standard MS-6395. Refer to your engine oil filler cap for correct SAE
grade.
259

Component Fluid, Lubricant, or Genuine Part
Engine Oil — 2.2L Diesel Engine For best performance and maximum protection under all types of operating conditions, the
manufacturer recommends SELENIA WR FORWARD engine oils, or equivalent, API Certified
SAE 0W-30 that meet the requirements of FCA Material Standard 9.55535- DS1,
MS.90047, and ACEA C2.
NOTE:
• If lubricants compliant with the required specifications are not available, products that
comply with the minimum required characteristics can be used for topping off; in this
case optimal performance of the engine is not guaranteed.
• The use of products with specifications other than those indicated above could cause
damage to the engine not covered by the warranty.
Engine Oil Filter We recommend you use Mopar Engine Oil Filter or equivalent.
Spark Plugs We recommend you use Mopar Spark Plugs.
Fuel Selection — 2.0L Gasoline Engine Minimum 97 Research Octane Number (RON) (EN228 Specifications)
Fuel Selection — 3.6L Gasoline Engine Minimum 91 Research Octane Number (RON) (EN228 Specifications)

CAUTION!
• Mixing of engine coolant (antifreeze)
other than specified Organic Additive
Technology (OAT) engine coolant (anti-
freeze), may result in engine damage
and may decrease corrosion protection.
CAUTION!
Organic Additive Technology (OAT) en-
gine coolant is different and should not
be mixed with Hybrid Organic Additive

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

CAUTION!
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 an-
tirust products, as they may not be com-
patible 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
CAUTION!
glycol-based engine coolant (antifreeze)
is not recommended.
• The use of products with different speci-
fications than those indicated above
could cause damage to the engine that
is not covered by the warranty.
• Use AdBlue only according to DIN
70 070 and ISO 22241-1. Other fluids
may cause damage to the system: also
exhaust emissions would no longer com-
ply with the law.
CAUTION!
• The distribution companies are respon-
sible for the compliance of their prod-
uct. Observe the precautions of storage
and servicing, in order to preserve the
initial qualities. The manufacturer of the
vehicle does not recognize any guaran-
tee in case of malfunctions and damage
caused to the vehicle due to the use of
UREA (AdBlue) not in accordance with
regulations.

requirement of FCA Material Standard 9.55550-AV4 or MS.9602.
FUEL CONSUMPTION AND
CO
2EMISSIONS
The fuel consumption and CO2emission
figures declared by the manufacturer are de-
termined on the basis of the type-approval
tests laid down by the applicable standards
in the country where the vehicle is registered.
The type of route, traffic conditions, weather
conditions, driving style, general condition of
the vehicle, trim level/equipment/ accesso-
ries, use of the climate control system, ve-
hicle load, presence of roof racks and othersituations that adversely affect the aerody-
namics or wind resistance lead to different
fuel consumption values than those mea-
sured.
The fuel consumption will only become more
regular after driving the first 1,864 miles
(3000 km).
To find the specific fuel consumption and
CO
2emission figures for this vehicle, please
refer to the data in the Certificate of Confor-
mity, and the related documentation that
accompanies the vehicle.
