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.
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.
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 responsibility of the manufacturer
and may void or not be covered under New Vehicle
Limited Warranty.

DO NOT USE E-85 IN NON-FLEX FUEL
V
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.
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.

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).

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 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.
FUEL SYSTEM CAUTIONS
NOTE:Intentional tampering with the emissions control
system can result in civil penalties being assessed
against you.
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 emis -
sions 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 autho -
rized dealer for service assistance.
The use of fuel additives, which are now being
sold as octane enhancers, is not recom -
mended. Most of these products contain high
concentrations of methanol. Fuel system
damage or vehicle performance problems
resulting from the use of such fuels or addi -
tives is not the responsibility of the manufac-
turer and may void or not be covered under
the New Vehicle Limited Warranty.
CAUTION!
