FUEL REQUIREMENTS
These engines are designed to meet all
emission regulations, and provide
satisfactory fuel economy and
performance when using high-quality
unleaded regular gasoline having a posted
octane number of 87 as specified by the
(R+M)/2 method. For optimal performance the
use of 91 or higher octane premium gasoline is
recommended in these engines.
While operating on gasoline with the required
octane number, 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 a lower than recommended
octane number 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 considering service for the
vehicle.
REFORMULATED GASOLINE
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.
GASOLINE/OXYGENATE BLENDS
Some fuel suppliers blend unleaded gasoline
with oxygenates such as ethanol.
Problems that result from using gasoline
containing more than 15% ethanol (E-15) or
gasoline containing methanol are not the respon -
sibility of the manufacturer and not covered
under New Vehicle Limited Warranty.
CNG AND LP FUEL SYSTEM
M
ODIFICATIONS
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 components.
Problems that result from running CNG or LP are
not the responsibility of the manufacturer and not
covered under the New Vehicle Limited Warranty.
METHYLCYCLOPENTADIENYL MANGANESE
T
RICARBONYL (MMT) IN GASOLINE
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. Gasoline 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.
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 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. 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
diaphragm materials.
CAUTION!
DO NOT use E-85, gasoline containing metha -
nol, 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 emis -
sions 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).

FUEL SYSTEM CAUTIONS

NOTE:
Intentional tampering with the emissions control system can result in civil penalties being assessed against you.
FLUID CAPACITIES
2.0L ENGINE
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 performance and damage the emissions control
system.
An out-of-tune engine or certain fuel or ignition 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
methanol. Fuel system damage or vehicle performance problems resulting from the use of such fuels or additives is not the responsibility of the
manufacturer and may void or not be covered under the New Vehicle Limited Warranty.
