What You Need to Know About Gasoline: Octane Rating, Myth Busters, and More

🔥Octane rating refers to a fuel's resistance to combustion under pressure. Higher octane fuels are recommended for engines with higher compression ratios or forced induction.

💡Octane rating does not directly relate to the power output of the engine. It is not an indicator of energy content or burn characteristics of the fuel.

❌Myths around octane levels, such as different energy content, burn temperature, or cleanliness, are false. Different octane fuels contain the same energy content and burn at the same temperature and speed.

⚠️Using lower octane fuel in an engine that requires high octane can lead to poor performance and potential engine damage. The engine's electronic control unit (ECU) may adjust engine timing, but power and fuel economy can suffer.

✅Using higher octane fuel than required may improve performance and fuel economy in certain driving conditions, such as towing or carrying heavy loads.

What is the octane rating of gasoline?

—The octane rating of gasoline refers to its resistance to combustion under pressure. Higher octane fuels have a higher resistance to combustion.

Does higher octane fuel provide more power?

—No, octane rating does not directly relate to the power output of the engine. It is primarily related to the engine's compression ratio and forced induction.

Can using lower octane fuel damage the engine?

—Yes, using lower octane fuel than required in an engine that needs higher octane can lead to poor performance and potential engine damage.

Will using higher octane fuel improve fuel economy?

—Using higher octane fuel than required may improve fuel economy in certain driving conditions, such as towing or carrying heavy loads.

What is the recommended fuel grade for my vehicle?

—The recommended fuel grade for your vehicle can be found in the owner's manual or on the fuel door. It is best to follow the manufacturer's guidelines.
