octane Hyundai Azera 2011 Owner's Manual

Introduction
Gasoline engine
Unleaded
For Europe
For the optimal vehicle performance, we
recommend you to use unleaded gaso-
line which complies with EN 228 and has
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.
Except Europe
Your new HYUNDAI vehicle is designed
to use only unleaded fuel having an
Octane Rating of RON (Research
Octane Number) 91 / AKI (Anti-Knock
Index) 87 or higher.
Your new vehicle is designed to obtain
maximum performance with UNLEADED
FUEL, as well as minimize exhaust emis-
sions and spark plug fouling.
Leaded (if equipped)
For some countries, your vehicle is
designed to use leaded gasoline. When
you are going to use leaded gasoline,
ask an authorized HYUNDAI dealer
whether leaded gasoline in your vehicle
is available or not.
Octane rating of leaded gasoline is same
with unleaded one.
FUEL REQUIREMENTS
WARNING
• Do not "top off" after the nozzle
automatically shuts off when
refueling.
• Always check that the fuel cap is
installed securely to prevent fuel
spillage in the event of an acci-
dent.
CAUTION
NEVER USE LEADED FUEL. The
use of leaded fuel is detrimental to
the catalytic converter and will
damage the engine control sys-
tem’s oxygen sensor and affect
emission control.
Never add any fuel system cleaning
agents to the fuel tank other than
what has been specified. (Consult
an authorized HYUNDAI dealer for
details.)
