Introduction
Other fuels
Using fuels such as;
- Silicone (Si) contained fuel,
- MMT (Manganese, Mn) contained
fuel,
- Ferrocene (Fe) contained fuel, and
- Other metallic additives contained
fuels,
may cause vehicle and engine dam-
age or cause plugging, misfiring,
poor acceleration, engine stalling,
catalyst melting, abnormal corrosion,
life cycle reduction, etc.
Also, the Malfunction Indicator Lamp
(MIL) may illuminate.Damage to the fuel system or per-
formance problem caused by the
use of these fuels may not be cov-
ered by your New Vehicle Limited
Warranty.
Use of MTBE
HYUNDAI recommends avoiding
fuels containing MTBE (Methyl
Tertiary Butyl Ether) over 15.0% vol.
(Oxygen Content 2.7% weight) in
your vehicle.
Fuel containing MTBE over 15.0%
vol. (Oxygen Content 2.7% weight)
may reduce vehicle performance and
produce vapour lock or hard starting.
Do not use methanol
Fuels containing methanol (wood
alcohol) should not be used in your
vehicle. This type of fuel can reduce
vehicle performance and damage
components of the fuel system,
engine control system and emission
control system.
Fuel Additives
HYUNDAI recommends that you use
unleaded fuel having an Octane
Rating of RON (Research Octane
Number) 91 / AKI (Anti-Knock Index)
87 or higher.
For customers who do not use good
quality petrols including fuel addi-
tives regularly, and have problems
starting or the engine does not run
smoothly, add one bottle of additives
to the fuel tank every 15,000 km.
Additives are available from your
authorised HYUNDAI dealer along
with information on how to use them.
Do not mix other additives.
NOTICE
Your New Vehicle Limited
Warranty may not cover dam-
age to the fuel system and any
performance problems that are
caused by the use of fuels con-
taining methanol or fuels con-
taining MTBE (Methyl Tertiary
Butyl Ether) over 15.0% vol.
(Oxygen Content 2.7% weight.)
CAUTION
Never use fuel which contains
methanol. Discontinue use of
any petrol containing ethanol
which impairs drivability.
