2018 HYUNDAI I30 fuel additives

F7
Introduction
Leaded (if equipped)
For some countries, your vehicle is
designed to use leaded gasoline.
When you are going to use leaded
gasoline, we recommend that you
ask an authorized HYUNDAI dealer.
Octane rating of leaded gasoline is
same with unleaded one.
Gasoline containing alcohol andmethanol
Gasohol, a mixture of gasoline and
ethanol (also known as grain alco-
hol), and gasoline or gasohol con-
taining methanol (also known as
wood alcohol) are being marketed
along with or instead of leaded or
unleaded gasoline.
Do not use gasohol containing more
than 10% ethanol, and do not use
gasoline or gasohol containing any
methanol. Either of these fuels may
cause drivability problems and dam-
age to the fuel system, engine control
system and emission control system.
Discontinue using gasohol of any
kind if drivability problems occur. Vehicle damage or driveability prob-
lems may not be covered by the
manufacturer’s warranty if they result
from the use of:
1. Gasohol containing more than
10% ethanol.
2. Gasoline or gasohol containing methanol.
3. Leaded fuel or leaded gasohol.
Other fuels
Using fuel additives such as:
- Silicone fuel additive
- MMT (Magnanese, Mn) fuel additive
- Ferrocene (iron-based) fuel additive
- Other metallic-based fuel additives
may result in cylinder misfire, poor
acceleration, engine stalling, dam-
age to the catalyst, or abnormal cor-
rosion, and may cause damage to
the engine resulting in a reduction in
the overall life of the powertrain.
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.
NOTICE
Never use gasohol which con-
tains methanol. Discontinue
use of any gasohol product
which impairs drivability.
CAUTION

Introduction
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 vapor 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 gasoline which has an
octane rating of RON (Research
Octane Number) 95 / AKI (Anti Knock
Index) 91 or higher (for Europe) or
Octane Rating of RON (Research
Octane Number) 91 / AKI (Anti-Knock
Index) 87 or higher (except Europe).
For customers who do not use good
quality gasolines including fuel addi-
tives regularly, and have problems
starting or the engine does not run
smoothly, one bottle of additives added
to the fuel tank at every 15,000km (for
Europe) / 10,000km (except Europe).
Additives are available from your
authorized HYUNDAI dealer along
with information on how to use them.
Do not mix other additives.
Operation in foreign countries
If you are going to drive your vehicle
in another country, be sure to:
Observe all regulations regarding registration and insurance.
Determine that acceptable fuel is available.
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

Diesel engine
Diesel fuel
Diesel engine must be operated only
on commercially available diesel fuel
that complies with EN 590 or compa-
rable standard. (EN stands for
"European Norm"). Do not use
marine diesel fuel, heating oils, or
non-approved fuel additives, as this
will increase wear and cause dam-
age to the engine and fuel system.
The use of non-approved fuels and /
or fuel additives will result in a limita-
tion of your warranty rights.
Diesel fuel of above cetane 51 is
used in your vehicle. If two types of
diesel fuel are available, use summer
or winter fuel properly according to
the following temperature conditions.
Above -5°C (23°F) ... Summer typediesel fuel.
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 com-
pletely purged to permit restarting.
Biodiesel
Commercially supplied Diesel blends
of no more than 7% biodiesel, com-
monly known as "B7 Diesel" may be
used in your vehicle if Biodiesel meets
EN 14214 or equivalent specifications.
(EN stands for "European Norm"). The
use of biofuels exceeding 7% made
from rapeseed methyl ester (RME),
fatty acid methyl ester (FAME), veg-
etable oil methyl ester (VME) etc. or
mixing diesel exceeding 7% with
biodiesel will cause increased wear or
damage to the engine and fuel sys-
tem. Repair or replacement of worn or
damaged components due to the use
of non approved fuels will not be cov-
ered by the manufactures warranty.

Introduction
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 jam-
ming the injection pump and
damaging the engine.
CAUTION
It is recommended to use the
regulated automotive diesel
fuel for diesel vehicle equipped
with the DPF system.
If you use diesel fuel including
high sulfur (more than 50 ppm
sulfur) and unspecified addi-
tives, it can cause the DPF sys-
tem to be damaged and white
smoke can be emitted.
CAUTION
Never use any fuel, whether
diesel, B7 biodiesel or other-
wise, that fails to meet the lat-
est petroleum industry speci-
fication.
Never use any fuel additives
or treatments that are not rec-
ommended or approved by
the vehicle manufacturer.

Maintenance
I : Inspect and if necessary, adjust, correct, clean or replace.
R : Replace or change.
** : The engine oil level should be checked regularly and maintained properly. Operating with an insufficient amount of oil can dam-
age the engine, and such damage is not covered by warranty.
*
1: Inspect drive belt tensioner, idler and alternator pulley and if necessary correct or replace.
*2: Check the engine oil level and leak every 500 km (350 miles) or before starting a long trip.
*3: If good quality gasolines meet Europe Fuel standards (EN228) or equivalents including fuel additives is not available, one bot -
tle of additive is recommended. Additives are available from your authorized HYUNDAI dealer along with information on how to
use them. Do not mix other additives.

Lean NOx Trap (if equipped)
The Lean NOx Trap (LNT) system
removes the nitrogen oxide in the
exhaust gas. The smell can occur in
the exhaust gas depending on the
quality of the fuel and it can degrade
NOx reduction performance, please
use the regulated automotive diesel
fuel.
Diesel Fuel
(if equipped with DPF)
We recommend you to use only
the regulated diesel fuels, when
your vehicle is equipped with
the DPF system.
When you use other diesel fuels,
which is high in sulfurs (above
50 ppm) or contains unspecified
additives, it may damage the
DPF system and cause the white
smoke emission.CAUTION
