TECHNICAL SPECIFICATIONS

FUEL
REQUIREMENTS
This engine is
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
optimum performance and fuel
economy the use of “Premium”
91 octane gasoline or higher is
recommended.
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 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.
Caution!
DO NOT use 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
the manufacturer and may void or not
be covered under New Vehicle Limited
Warranty.
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 components. 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. 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.
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 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 your 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.
Note:
Intentional tampering with the
emissions control system can result in
civil penalties being assessed against
you.
