2021 JEEP GRAND CHEROKEE fuel type

Reformulated Gasoline
Many areas of the country require the use of
cleaner burning gasoline referred to as “Re-
formulated Gasoline”. Reformulated gaso-
line contains oxygenates and are specifically
blended to reduce vehicle emissions and im-
prove air quality.
The use of reformulated gasoline is recom-
mended. Properly blended reformulated
gasoline will provide improved performance
and durability of engine and fuel system
components.
Do Not Use E-85 In Non-Flex Fuel
Vehicles
Non-Flex Fuel Vehicles (FFV) are compatible
with gasoline containing up to 15% ethanol
(E-15). Use of gasoline with higher ethanol
content may void the New Vehicle Limited
Warranty.If a Non-FFV vehicle is inadvertently fueled
with E-85 fuel, the engine will have some or
all of these symptoms:
• Operate in a lean mode.
• OBD II Malfunction Indicator Light on.
• Poor engine performance.
• Poor cold start and cold drivability.
• Increased risk for fuel system component
corrosion.
CNG And LP Fuel System Modifications
Modifications that allow the engine to run on
Compressed Natural Gas (CNG) or Liquid
Propane (LP) may result in damage to the
engine, emissions, and fuel system compo-
nents. Problems that result from running
CNG or LP are not the responsibility of the
manufacturer and may void or not be covered
under the New Vehicle Limited Warranty.
Materials Added To Fuel
Indiscriminate use of fuel system cleaning
agents should be avoided. Many of these
materials intended for gum and varnish re-
moval may contain active solvents or similar
ingredients. These can harm fuel system gas-
ket and diaphragm materials.
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).

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 sea-
son: summer type, winter type and arctic type
(cold/mountain areas).This vehicle must only
use premium diesel fuel that meets the require-
ments 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.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 fuel/water separator drain pro-
vided 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” re-
mains 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” in your Owner’s Manual
for further information.

FUEL CONSUMPTION AND
CO
2EMISSIONS
The fuel consumption and CO2emission fig-
ures declared by the manufacturer are deter-
mined 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 other
situations 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 (if equipped), and the related documen-
tation that accompanies the vehicle (if
equipped).
