Fuel requirements
Gasoline engine (unleaded) Your new Kia vehicle is designed to use only unleaded fuel with a minimum Octane Rating of 87 Anti-Knock Index (AKI).
NOTICE
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 Kia has specified. (Consult an Authorized Kia Dealer for details.)
Gasoline containing alcohol and
methanol
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 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 damage to the fuel system.
Discontinue using gasohol of any kind if drivability problems occur.
Vehicle damage or driveability problems
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.
NOTICE
Never use gasohol which contains
methanol. Discontinue use of any gasohol
product which impairs drivability.
