Gasoline engine

Unleaded

For the optimal vehicle performance, we recommend you use unleaded gasoline which 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. (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.

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.

  • 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.

Gasoline containing ethanol 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, engine control system, and emission control 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.

Never use gasohol which contains methanol. Discontinue use of any gasohol product which impairs drivability.

Other fuels

Using fuel additives such as:

  • Silicone fuel additive

  • MMT (Manganese, Mn) fuel additive

  • Ferrocene (iron-based) fuel additive

  • Other metallic-based fuel additives

may result in cylinder misfire, poor acceleration, engine stalling, damage to the catalyst, or abnormal corrosion, and may cause damage to the engine resulting in a reduction in the overall life of the powertrain.

Damage to the fuel system or performance problem caused by the use of these fuels may not be covered by your New Vehicle Limited Warranty.

Use of MTBE

Genesis Branded Vehicle recommends avoiding fuels containing 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 reduce vehicle performance and produce vapor lock or hard starting.

Your New Vehicle Limited Warranty may not cover damage to the fuel system and any performance problems that are caused by the use of fuels containing methanol or fuels containing MTBE (Methyl Tertiary Butyl Ether) over 15.0 % vol. (Oxygen Content 2.7 % weight.)

Do not use methanol

Fuels containing methanol (wood alcohol) should not be used in your vehicle. This type of fuel can reduce vehicle performance and damage components of the fuel system, engine control system, and emission control system.

Fuel additives

Genesis Branded Vehicle 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 customers who do not use good quality gasolines, and have problems starting or the engine does not run smoothly, one bottle of additive added to the fuel tank is recommended according to the maintenance schedule (refer to chapter 9, "Normal maintenance schedule (except Europe, but including Russia)" or "Normal maintenance schedule (for Europe)").

Additives are available from your authorized retailer of Genesis Branded products along with information on how to use them. Do not mix other additives.

Never add any fuel system cleaning agents or other additives to the fuel tank other than what has been specified to prevent damage to the engine and engine components. We recommend that you contact an authorized retailer of Genesis Branded products for additional information.

Operation in foreign countries

If you are going to drive your vehicle in another country, be sure to:

  • Observe all regulations regarding registration and insurance.

  • Determine that acceptable fuel is available.
