Have you ever noticed your vehicle’s engine running unevenly while driving? Or perhaps you’ve heard the knocking sound coming from the engine? These issues are often the result of low octane fuel. In this article, we will explore the impact of octane number on combustion, global standards, and the current situation in Iran regarding this matter.

What is Octane Number and Why is it Important?

The octane number is a measure of a fuel’s resistance to early combustion or engine knocking. The higher this number, the more stable the fuel is and the better it integrates with advanced combustion systems.

Comparing Octane Numbers in Iran and the World

Europe and the United States: Standard fuels typically have octane ratings of 91, 95, and 98. Depending on the type of vehicle, drivers can choose the appropriate octane level for optimal engine performance.

Iran: In our country, the fuel mainly has an octane rating ranging from 87 to 91, which is lower compared to developed countries.

Japan and South Korea: In these countries, gasoline with octane ratings ranging from 95 to 100 is common, leading to improved engine performance and reduced emissions.

Global Octane Number Standards

RON (Research Octane Number): This is the primary measurement used in many countries to assess the fuel’s resistance to knocking under standard conditions.

MON (Motor Octane Number): It evaluates fuel under more challenging conditions, such as high temperatures and pressures.

AKI (Anti-Knock Index): It is the average of RON and MON and is used primarily in the United States.

If you are looking to enhance engine power, reduce wear and tear, and improve fuel efficiency, paying attention to the fuel’s octane number is essential. Advanced countries have maintained high standards in this area for years, while in Iran, there is still room for improvement in fuel quality. Therefore, using fuel additives is a smart investment for better performance and extended lifespan of your vehicle.
