2018 KIA STONIC octane

FUEL REQUIREMENTS
Gasoline engine
Unleaded
For Europe
For the optimal vehicle performance,
we recommend you to use unleaded gasoline with an octane rating of RON
(Research Octane Number) 95 / AKI
(Anti Knock Index) 91 or higher.
You may use unleaded gasoline with an octane rating of RON 91~94 / AKI 87~90
but it may result in slight performance
reduction of the vehicle. (Do not use methanol blended fuels.)
Except Europe
Your new Kia vehicle is designed to use
only unleaded fuel having an Octane
Rating of RON (Research Octane Num‐ ber) 91 / AKI (Anti-Knock Index) 87 or
higher. (Do not use methanol blended
fuels.)
Your new vehicle is designed to obtain maximum performance with UNLEA‐
DED FUEL, as well as minimize exhaust
emissions and spark plug fouling.
CAUTION
NEVER USE LEADED FUEL. The useof leaded fuel is detrimental to thecatalytic converter and will damagethe engine control system’s oxygensensor and affect emission control.Never add any fuel system cleaningagents to the fuel tank other thanwhat has been specified. (Kia recom‐mends to consult an authorized Kiadealer/service partner for details.)
WARNING
•Do not "top off" after the nozzleautomatically shuts off when re‐fueling.
•Always check that the fuel cap isinstalled securely to prevent fuelspillage in the event of an acci‐dent.
Leaded (if equipped)
For some countries, your vehicle is de‐
signed to use leaded gasoline. When you are going to use leaded gasoline,
Kia recommends to visit an authorized
Kia dealer/service partner and ask whether leaded gasoline in your vehicle
is available or not.
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 alcohol),
and gasoline or gasohol containing methanol (also known as wood alcohol)
are being marketed along with or in‐
stead of leaded or unleaded gasoline.
Do not use gasohol containing more than 10% ethanol, and do not use gas‐
oline or gasohol containing any metha‐
nol. Either of these fuels may cause drivability problems and damage to the
fuel system, engine control system and
emission control system.
Discontinue using gasohol of any kind if drivability problems occur.
Vehicle damage or drivability problems
may not be covered by the manufac‐
turer’s warranty if they result from the use of:

Introduction

1. Gasohol containing more than 10%ethanol.
2. Gasoline or gasohol containing methanol.
3. Leaded fuel or leaded gasohol.
CAUTION
Never use gasohol which containsmethanol. Discontinue use of anygasohol product which impairs driva‐bility.
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
damage or cause plugging, misfiring, poor acceleration, engine stalling,
catalyst melting, abnormal corrosion,
life cycle reduction, etc.
Also, the Malfunction Indicator Lamp
(MIL) may illuminate.
NOTICE
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
Kia recommends avoiding fuels contain‐ ing 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 re‐
duce vehicle performance and produce
vapor lock or hard starting.
CAUTION
Your New Vehicle Limited Warrantymay not cover damage to the fuelsystem and any performance prob‐lems that are caused by the use offuels containing methanol or fuelscontaining MTBE (Methyl TertiaryButyl Ether) over 15.0% vol. (OxygenContent 2.7% weight.)
Do not use methanol
Fuels containing methanol (wood alco‐ hol) should not be used in your vehicle.
This type of fuel can reduce vehicle
performance and damage components of the fuel system, engine control sys‐
tem and emission control system.
Fuel Additives
Kia 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 (Re‐ search Octane Number) 91 / AKI (Anti-
Knock Index) 87 or higher (except Eu‐
rope).
For customers who do not use good quality gasolines including fuel additives
regularly, and have problems starting
or the engine does not run smoothly, one bottle of additives added to the
fuel tank at every 15,000 km (For Eu‐
rope) / 10,000 km (Except Europe). Ad‐ ditives are available from a professional
workshop along with information on
how to use them. Kia recommends to visit an authorized Kia dealer/service
partner. Do not mix other additives.
