B010B01A-AAT 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 developsdriveability problems, the use of 100% unleaded gasoline is recommended. Fuels with unspecified quantities ofalcohol, or alcohols other than ethanol, should not be used. B010D01S-AAT Do not Use Methanol Fuels containing methanol (wood al- cohol) should not be used in yourHyundai. This type of fuel can reduce vehicle performance and damage com- ponents of the fuel system. B010E01A-AAT Gasolines for Cleaner Air To help contribute to cleaner air, Hyundai recommends that you use gasolines treated with detergent addi- tives, which help prevent deposit for-mation in the engine. These gasolines will help the engine run cleaner and enhance performance of the EmissionControl System.
B010A02A-GAT FUEL RECOMMENDATIONS Use Unleaded Gasoline Unleaded gasoline with a Pump Oc- tane Rating of 87 (Research Octane Number 91) or higher must be used in Hyundai vehicle. If leaded gasoline isused, it will cause the catalytic con- verter to become ineffective and the emission control system to malfunc-tion. This can also result in increased main- tenance expense. To avoid accidentaluse of leaded fuel, the large nozzle used with leaded gasoline at service stations can not be inserted into fueltank opening of Hyundai vehicle.
NOTE:
o For some countries, Hyundai ve-
hicles are designed to use leaded gasoline. When you are going to use leaded gasoline, ask to Hyundai dealer whether leadedgasoline in your vehicle is avail- able or not.
o Octane Rating of leaded gaso- line is same with unleaded one.

! CAUTION:
Your Hyundai's New Vehicle Lim- ited Warranty may not cover dam- age to the fuel system and perfor-mance problems that are caused by the use of methanol or fuels con- taining methanol.
