Fuel Requirements; 僅 Petrol Engine - Kia Sonet 2024 Owner's Manual

Fuel requirements

Petrol engine
Unleaded
Your new vehicle is designed to use only
unleaded fuel having an Octane Rating
of RON (Research Octane Number) 91/
AKI (Antiknock Index) 87 or higher. (Do
not use methanol blended fuels)
Your new vehicle is designed to obtain
maximum performance with UNLEADED
FUEL, as well as minimize exhaust emis-
sions and spark plug fouling.
CAUTION
NEVER USE LEADED FUEL. The use of
leaded fuel is detrimental to the catalytic
converter and will damage the engine
control system's oxygen sensor and
affect emission control.
Never add any fuel system cleaning
agents to the fuel tank other than what
has been specified. (Kia recommends to
consult an authorised Kia dealer/service
partner for details.)
WARNING
僅 Do not "top off" after the nozzle auto-
matically shuts off when refueling.
僅 Always check that the fuel cap is
installed securely to prevent fuel spill-
age in the event of an accident.
Petrol containing alcohol and
methanol
Gasohol, a mixture of petrol and ethanol
(also known as grain alcohol), and petrol
or gasohol containing methanol (also
known as wood alcohol) are being mar-
1 2
keted along with or instead of leaded or
unleaded petrol.
Do not use gasohol containing more
than 20% ethanol, and do not use petrol
or gasohol containing any methanol.
Either of these fuels may cause drivabil-
ity problems and damage to the fuel
system, engine control system and emis-
sion 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:
1. Gasohol containing more than 20%
ethanol.
2. Petrol or gasohol containing metha-
nol.
3. Leaded fuel or leaded gasohol.
CAUTION
Never use gasohol which contains meth-
anol. Discontinue use of any gasohol
product which impairs drivability.
Other fuels
Using fuels such as
僅 Silicone (Si) contained fuel,
僅 MMT (Methylcyclopentadienyl Man-
ganese Tricarbonyl), Manganese (Mn)
contained fuel,
僅 Ferrocene (Fe) contained fuel, and
僅 Other metallic additives contained
fuels,
may cause vehicle and engine damage
or cause plugging, misfiring, poor accel-
eration, engine stalling, catalyst melting,
abnormal corrosion, life cycle reduction,
etc.
