Fuel recommendations
Use Unleaded Gasoline

Unleaded gasoline with a Pump Octane Rating of 87 (Research Octane Number 91) or higher must be used in your Hyundai.
WARNING:
o Do not "top off" after the nozzle automatically
shuts off when refueling.
o Tighten the cap until it clicks, otherwise
the "
" light will illuminate.
o Always check that the fuel cap is installed
securely to prevent fuel spillage
in the event of an accident.
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 develops 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.
Use of MTBE
Hyundai recommends that fuels containing MTBE (Methyl Tertiary Butyl Ether) over 15.0% vol. (Oxygen Content 2.7% weight) should not be used in your Hyundai.
Fuel containing MTBE over 15.0% vol. (Oxygen Content 2.7% weight) may reduce vehicle performance and produce vapor lock or hard starting.
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 Warranty
may not cover damage to the fuel
system and any performance problems that
are caused by the use of fuels containing
methanol or fuels containing MTBE (Methyl
Tertiary Butyl Ether) over 15.0% vol. (Oxygen
Content 2.7% weight.)
Gasolines for Cleaner Air
To help contribute to cleaner air, Hyundai recommends 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 performance of the Emission Control System.
Operation in Foreign Countries
If you are going to drive your Hyundai in another
country, be sure to:
o Observe all regulations regarding registration
and insurance.
o Determine that acceptable fuel is available.
