KIA Niro: Unleaded gasoline

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 Number) 91/AKI (Anti- Knock 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 emissions and spark plug fouling.

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 accident.

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 authorized Kia dealer/service partner 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 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, 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 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.

CAUTION

Never use gasohol which contains methanol.

Discontinue use of any gasohol product which impairs drivability.
