FUEL RECOMMENDATIONS
Use Unleaded Gasoline
B010A01FC-1
Unleaded gasoline with a Pump Octane Rating
of 87 (Research Octane Number 91) or higher
must be used in Hyundai vehicle. If leaded
gasoline is used, it will cause the catalytic
converter to become ineffective and the emis-
sion control system to malfunction. This can
also result in increased maintenance expense.
To avoid accidental use of leaded fuel, the large
nozzle used with leaded gasoline at service
stations can not be inserted into fuel tank
opening of Hyundai vehicle.

FEATURES OF YOUR HYUNDAI

NOTE:
o For some countries, Hyundai vehicles
are designed to use leaded gasoline.
When you are going to use leaded gaso-
line, ask to Hyundai dealer whether leaded
gasoline in your vehicle is available or
not.
o Octane Rating of leaded gasoline is same
with unleaded one.
Use Diesel
Diesel fuel of 52 to 54 cetane is used in Hyundai
vehicle. If two types of diesel fuel are available,
use summer or winter fuel properly according to
the following temperature conditions.
o Above -5°C (23°F) ... Summer type diesel
fuel.
o Below -5°C (23°F) ... Winter type diesel fuel.
Watch the fuel level in the tank very carefully :
If the engine stops through fuel failure, the
circuits must be completely purged to permit
restarting.
CAUTION:
o Do not let any gasoline or water enter the
tank. This would make it necessary to
drain it out and to bleed the lines to avoid
jamming the injection pump and damag-
ing the engine.
o In winter, in order to cut down incidents
due to freezing, paraffin oil may be added
to the fuel if the temperature drops to
below -10°C. Never use more than 20%
paraffin oil.

What About Gasohol?
Gasohol (a mixture of 90% unleaded gasoline
and 10% ethanol or grain alcohol) may be used
in your Hyundai. However, if your engine devel-
ops driveability problems, the use of 100%
unleaded gasoline is recommended. Fuels with
unspecified quantities of alcohol, or alcohols
other than ethanol, should not be used.
B010D01S-AAT
Do not Use Methanol
Fuels containing methanol (wood alcohol)
should not be used in your Hyundai. This type
of fuel can reduce vehicle performance and
damage components of the fuel system.
CAUTION:
Your Hyundai's New Vehicle Limited War-
ranty may not cover damage to the fuel
system and performance problems that are
caused by the use of methanol or fuels
containing methanol.
B010E01A-AAT
Gasolines for Cleaner Air
To help contribute to cleaner air, Hyundai rec-
ommends that you use gasolines treated with
detergent additives, which help prevent deposit
formation in the engine. These gasolines will
help the engine run cleaner and enhance per-
formance of the Emission Control System.
