FUEL REQUIREMENTS

Hyundai Elantra fuel recommendations

Your new vehicle is designed to obtain maximum performance with UNLEADED FUEL, as well as minimize exhaust emissions and spark plug fouling.
Your new vehicle is designed to perform optimally using unleaded fuel having an octane number ((R+M)/2) of 87
(Research Octane Number 91) or higher. (Do not use methanol blended fuels)

NOTICE
To prevent damage to the engine and engine components, never add any fuel system cleaning agents to the fuel tank other than what has been specified.
Consult an authorized HYUNDAI dealer for additional information.

Hyundai Elantra 2023 Introduction05

WARNING

  • Do not “top off” after the nozzle automatically shuts off when refuelling.
  • Always check that the fuel cap is installed securely to prevent fuel spillage in the event of an accident.

Gasoline containing alcohol or methanol
Gasohol, a mixture of gasoline and ethanol (also known as grain alcohol) is being marketed along with or instead of leaded or unleaded gasoline. For example, “E15” is a gasohol comprised of 15% ethanol and 85% gasoline.
Do not use gasohol containing more than 15% 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.
“E85” fuel is an alternative fuel comprised of 85 per cent ethanol and 15 per cent gasoline and is manufactured exclusively for use in Flexible Fuel Vehicles. “E85” is not compatible with your vehicle. Use of “E85” may result in poor engine performance and damage to your vehicle’s engine and fuel system. HYUNDAI recommends that customers do not use fuel with an ethanol content exceeding 15 per cent.

NOTICE
To prevent damage to your vehicle’s engine and fuel system:

Fueling Tips

  • Never use gasohol which contains methanol.
  • Never use gasohol containing more than 15% ethanol.
  • Never use leaded fuel or leaded gasohol.
  • Never use “E85” fuel.
    Your New Vehicle Limited Warranty does not cover damage to the fuel system or any performance problems caused by the use of “E85” fuel.

Using Fuel-saving techniques (except Detergent Fuel Additives)
Using fuel additives such as:

  • Silicone 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.

  • The Malfunction Indicator Lamp (MIL) may illuminate.

NOTICE
Damage to the fuel system or performance problem caused by the use of these fuels or fuel additives may not be covered by your New Vehicle Limited Warranty.
Gasoline containing MMT
Some gasoline contains harmful manganese-based fuel additives such as MMT (Methylcyclopentadienyl Manganese Tricarbonyl).
HYUNDAI does not recommend the use of gasoline containing MMT.
This type of fuel can reduce vehicle performance and affect your emission control system.
The malfunctioning indicator lamp on the cluster may come on.

Detergent Fuel Additives

 Hyundai Elantra 2023 fuel type recommends that you use good quality gasoline treated with detergent additives such as TOP TIER Detergent Gasoline, which helps in your Engine Care and prevents deposit formation in the engine. These gasolines will help the engine run cleaner and enhance the performance of the Emission Control System. For more information on TOP TIER Detergent Gasoline, please go to the website (www. toptiergas.com).
For customers who do not use TOP Tier Detergent Gasoline regularly, and have problems starting or the engine does not run smoothly, detergent-based fuel additives that you can purchase separately may be added to the gasoline. If TOP TIER Detergent Gasoline is not available, one bottle of additive added to the fuel tank according to the maintenance schedule is recommended (refer to the Maintenance Schedule in Chapter 8).
Additives are available from your authorized HYUNDAI dealer along with information on how to use them. Do not mix other additives.

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.

VEHICLE MODIFICATIONS

  • This vehicle should not be modified.
    Modification of your vehicle could affect its performance, safety, or durability and may even violate governmental safety and emissions regulations.
    In addition, damage or performance problems resulting from any modification may not be covered under warranty.
  • If you use unauthorized electronic devices, it may cause the vehicle to operate abnormally, wire damage, battery discharge, and fire. For your safety, do not use unauthorized electronic devices.

VEHICLE break in PROCESS

By following a few simple precautions for the first 600 miles (1,000 km) you may add to the performance, economy, and life of your vehicle.

  • Do not race the engine.
  • While driving, avoid sudden acceleration and stop.
  • Do not maintain a single speed for long periods, either fast or slow. Varying engine speed is needed to properly break in the engine.
  • Fuel economy and engine performance may vary depending on the vehicle break-in process and be stabilized after 4,000 miles (6,000 km). New engines may consume more oil during the vehicle break-in period.
  • Avoid hard stops, except in emergencies, to allow the brakes to sit properly.
  • Do not tow a trailer during the first 1,200 miles (2,000 km) of operation.

VEHICLE DATA COLLECTION AND EVENT DATA

RECORDERS

This vehicle is equipped with an event data recorder (EDR). The main purpose of an EDR is to record, in certain crashes or near crash-like situations, such as an airbag deployment or hitting a road obstacle, data that will assist in understanding how a vehicle’s systems performed. The EDR is designed to record data related to vehicle dynamics and safety systems for a short period, typically 30 seconds or less. The EDR in this vehicle is designed to record such data as:

  • How various systems in your vehicle were operating;
  • Whether or not the driver and passenger safety belts were buckled/fastened;
  • How far (if at all) the driver was depressing the accelerator and/or brake pedal; and,
  • How fast the vehicle was travelling.
    These data can help provide a better understanding of the circumstances in which crashes and injuries occur. NOTE: EDR data is recorded by your vehicle only if a non-trivial crash situation occurs; no data are recorded by the EDR under normal driving conditions and no personal data (for example, name, gender, age, and crash location) are recorded. However, other parties, such as law enforcement, could combine the EDR data with the type of personally identifying data routinely acquired during a crash investigation.
    To read data recorded by an EDR, special equipment is required, and access to the vehicle or the EDR is needed. In addition to the vehicle manufacturer, other parties, such as law enforcement, that have the special equipment, can read the information if they have access to the vehicle or the EDR.
