2019 DODGE GRAND CARAVAN octane

After 25 miles (40 km), check the lug nut/bolt torque to be
sure that all the lug nuts/bolts are properly seated against
the wheel.
WARNING!
To avoid the risk of forcing the vehicle off the jack, do
not tighten the lug nuts/bolts fully until the vehicle has
been lowered. Failure to follow this warning may
result in personal injury.
FUEL REQUIREMENTS
3.6L Engine
This engine is designed to meet all emis-
sions regulations and provide excellent
fuel economy and performance when
using high-quality unleaded “Regular”
gasoline having an octane rating of 87 as
specified by the (R+M)/2 method. The
use of higher octane “Premium” gaso-
line will not provide any benefit over “Regular” gasoline in
these engines.
While operating on gasoline with an octane number of 87,
hearing a light knocking sound from the engine is not a
cause for concern. However, if the engine is heard making
a heavy knocking sound, see your dealer immediately. Use
of gasoline with an octane number lower than 87 can cause
engine failure and may void or not be covered by the New
Vehicle Limited Warranty.
Poor quality gasoline can cause problems such as hard
starting, stalling, and hesitations. If you experience these
symptoms, try another brand of gasoline before consider-
ing service for the vehicle.

Reformulated Gasoline
Many areas of the country require the use of cleaner burning
gasoline referred to as “Reformulated Gasoline”. Reformu-
lated gasoline contains oxygenates and are specifically
blended to reduce vehicle emissions and improve air quality.
The use of reformulated gasoline is recommended. Prop-
erly blended reformulated gasoline will provide improved
performance and durability of engine and fuel system
components.
Materials Added To Fuel
Besides using unleaded gasoline with the proper octane
rating, gasolines that contain detergents, corrosion and
stability additives are recommended. Using gasolines that
have these additives will help improve fuel economy,
reduce emissions, and maintain vehicle performance.Designated TOP TIER Detergent Gaso-
line contains a higher level of detergents
to further aide in minimizing engine
and fuel system deposits. When avail-
able, the usage of TOP TIER Detergent
gasoline is recommended. Visit
www.toptiergas.com for a list of TOP
TIER Detergent Gasoline Retailers. Indiscriminate use of fuel system cleaning agents should be
avoided. Many of these materials intended for gum and
varnish removal may contain active solvents or similar
ingredients. These can harm fuel system gasket and dia-
phragm materials.
Gasoline/Oxygenate Blends
Some fuel suppliers blend unleaded gasoline with oxygen-
ates such as ethanol.
CAUTION!
DO NOT use E-85, gasoline containing methanol, or
gasoline containing more than 15% ethanol (E-15). Use
of these blends may result in starting and drivability
problems, damage critical fuel system components,
cause emissions to exceed the applicable standard,
and/or cause the Malfunction Indicator Light to illu-
minate. Please observe pump labels as they should
clearly communicate if a fuel contains greater than 15%
ethanol (E-15).
Problems that result from using gasoline containing more
than 15% ethanol (E-15) or gasoline containing methanol are
not the responsibility of the manufacturer and may void or
not be covered under New Vehicle Limited Warranty.

TECHNICAL SPECIFICATIONS 391

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.
MMT In Gasoline
Methylcyclopentadienyl Manganese Tricarbonyl (MMT) is
a manganese-containing metallic additive that is blended
into some gasoline to increase octane. Gasoline blended
with MMT provides no performance advantage beyond
gasoline of the same octane number without MMT. Gaso-
line blended with MMT reduces spark plug life and
reduces emissions system performance in some vehicles.
The manufacturer recommends that gasoline without
MMT be used in your vehicle. The MMT content of
gasoline may not be indicated on the gasoline pump;
therefore, you should ask your gasoline retailer whether
the gasoline contains MMT. MMT is prohibited in Federal
and California reformulated gasoline.
Fuel System Cautions
CAUTION!
Follow these guidelines to maintain your vehicle’s
performance:
•The use of leaded gasoline is prohibited by Federal
law. Using leaded gasoline can impair engine perfor-
mance and damage the emissions control system.
• An out-of-tune engine or certain fuel or ignition
(Continued)
392 TECHNICAL SPECIFICATIONS

CAUTION!(Continued)
malfunctions can cause the catalytic converter to
overheat. If you notice a pungent burning odor or
some light smoke, your engine may be out of tune or
malfunctioning and may require immediate service.
Contact an authorized dealer for service assistance.
• The use of fuel additives, which are now being sold
as octane enhancers, is not recommended. Most of
these products contain high concentrations of metha-
nol. Fuel system damage or vehicle performance
problems resulting from the use of such fuels or
additives is not the responsibility of the manufac-
turer and may void or not be covered under the New
Vehicle Limited Warranty.
NOTE: Intentional tampering with the emissions control
system can result in civil penalties being assessed against
you.
Carbon Monoxide Warnings
WARNING!
Carbon monoxide (CO) in exhaust gases is deadly.
Follow the precautions below to prevent carbon mon-
oxide poisoning:
• Do not inhale exhaust gases. They contain carbon
monoxide, a colorless and odorless gas, which can
kill. Never run the engine in a closed area, such as a
garage, and never sit in a parked vehicle with the
engine running for an extended period. If the vehicle
is stopped in an open area with the engine running
for more than a short period, adjust the ventilation
system to force fresh, outside air into the vehicle.
• Guard against carbon monoxide with proper main-
tenance. Have the exhaust system inspected every
time the vehicle is raised. Have any abnormal condi-
tions repaired promptly. Until repaired, drive with
all side windows fully open.

FLEXIBLE FUEL (3.6L ENGINE ONLY)
E-85 General Information
The information in this section is unique for Flexible Fuel
vehicles only. These vehicles can be identified by a unique
fuel filler door label that statesEthanol (E-85) or Unleaded
Gasoline Only and/or a yellow fuel cap. Please refer to the
other sections of this manual for information on features
that are common between Flexible Fuel and Non-Flexible
Fuel powered vehicles.
CAUTION!
Only vehicles with the E-85 fuel filler door label or a
yellow gas cap can operate on E-85.
Ethanol Fuel (E-85)
E-85 is a mixture of approximately 85% ethanol and 15%
unleaded gasoline.
WARNING!
Ethanol vapors are extremely flammable and could
cause serious personal injury. Never have any smoking
materials lit or products that can cause spark in or near
the vehicle when removing the fuel filler tube cap (gas
cap) or filling the tank. Do not use E-85 as a cleaning
agent and never use it near an open flame.
Fuel Requirements
If your vehicle is E-85 compatible, it will operate on
unleaded gasoline with any octane rating greater than 87
(R+M)/2, or solely E-85 fuel, or any mixture of these fuels.
For best results, avoid fueling patterns alternating be-
tween E-85 and unleaded gasoline.
When switching fuel types:
• Add 5 gallons (19 liters) or more when refueling.
• Drive the vehicle immediately after refueling for at least
5 miles (8 km).
Observing these precautions will avoid possible hard start-
ing and/or driveability problems during warm up.
