Octane Rating

It is the measures of fuel stability and it also measure the ability of fuel to avoid knock that occurs when fuel is prematurely ignited in the engine’s cylinder. Knock degrades the efficiency and can damage the engine. Higher is the octane number, petrol mixture would be more resistant to knock. The fuel has a niche market for luxury vehicles demanding the high performance. It is available only in 6 countries namely, the United States of America, Greece, Germany, Indonesia, Israel, and Malaysia.

Grades of Octane

At most of the retail stations, there are three octane grade:

  • 87 octane means the regular fuel
  • 89 octane means a mid-grade fuel
  •  91-94 octane means premium fuel.


Recently HPCL had launched Octane 99. Now, the IOC has launched the XP100. Through this, India is becoming more self reliant. Earlier, India had leapfrogged from BS-IV (Euro-IV) fuel to BS-VI emission compliant fuel.

Why do luxury vehicles require higher Octane grade fuels?

When the level of the fuel is higher, that is, when the fuel is of higher-Octane grade, the cylinders do not ignite as quickly as that of a regular gas engine cylinders. The luxury vehicles require premium fuel due to their high performance engines that demand higher levels of Octane. Using a regular fuel in a luxury vehicle will lead to knocking hand eventual wear and tear of the engine.
