“Does higher octane mean better performance?” or “Which one is best for my car?” If these types of questions concern you, you’ve come to the right place!

In this article What is octane? We explain in detail the differences between petrol types and which octane number is suitable for your vehicle. Let’s get started!

What is octane and what does it do?

Octane is used to ensure efficient engine operation during the combustion of gasoline. A measure that indicates how much resistance it offers. In more technical terms we can say that it is the ability to prevent a spontaneous explosion when gasoline becomes trapped in the combustion chamber of the engine.

As the octane number increases, the fuel burns in a more controlled manner more resistant to impacts it becomes. This means a more efficient and quieter engine.

How are octane numbers determined?

ASTM D910 standard The octane number is determined by . In the controlled fire test, the burning speed is measured by the production of pressure waves. While iso-octane burns slowly and in a controlled manner, n-heptane burns quickly and uncontrollably. If the combustion rate of gasoline is closer to iso-octane, the octane number is higher.

What are the octane types and the differences between them?

Octane number 95 is the fuel type commonly used in Turkey. Standard motor vehicles Ideal for fuel economy, 95 octane is also used as a standard fuel and is suitable for a wide range of vehicles. If your vehicle does not have an engine that requires high performance, that is, if you use a regular passenger car, you can choose an octane number of 95.

Gasoline with an octane number of 97, It is used in powerful engines. It is generally the choice of owners of sports and performance vehicles. Compared to 95 octane, it can make your engine run a little more efficiently and provide consistent power.

Gasoline with an octane number of 98 turbo petrol engines and racing cars Ideal fuel type for The vehicle can operate at maximum efficiency with this fuel, which is designed to withstand high compression ratios. Its use in regular vehicles is not recommended as the expected performance is not achieved.

Know your vehicle well before determining its octane rating.

When choosing octane, you should really focus on your vehicle’s engine structure and your usage style. your vehicle in the user manual It usually states which octane number of fuel you should use.

Using the wrong octane number can cause a loss of engine performance. increased fuel consumption or may cause long-term mechanical problems.

Not anymore at the next refueling. Which octane should you choose? you know better! With the help of this information you can now make the right choice and enjoy your trip.
