348 TECHNICAL SPECIFICATIONS
The use of 89 octane "Plus" gasoline is
recommended for optimum performance and
fuel economy.

EFORMULATED ASOLINE
Many areas of the country require the use
of cleaner burning gasoline referred to as
"reformulated gasoline". Reformulated
gasoline contains oxygenates and are
specifically blended to reduce vehicle
emissions and improve air quality.
The use of reformulated gasoline is
recommended. Properly blended reformulated
gasoline will provide improved performance
and durability of engine and fuel system
components.

ATERIALS DDED O UEL
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
Gasoline contains a higher level
of detergents to further aide in
minimizing engine and fuel system deposits.
When available, the usage of TOP TIER
Detergent Gasoline is recommended.

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 diaphragm materials.
G /O B
ASOLINE XYGENATE LENDS
Some fuel suppliers blend unleaded gasoline
with oxygenates 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 illuminate. 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 FCA and may void the New
Vehicle Limited Warranty.

EHICLES
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.

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.
