What is ‘Octane’ rating?

  • Octane ratings are measures of fuel stability.
  • It is a measure of a fuel’s ability to avoid knock. A prolonged occurrence of engine knocking can cause serious damage to the engines inner parts.
  • Knock occurs when fuel is prematurely ignited in the engine’s cylinder, which degrades efficiency and can be damaging to the engine.
  • The higher the octane number, the more resistant the petrol mixture is to knock.
  • Worldwide, 100 Octane petrol has a niche market for luxury vehicles that demand high performance and is available only in six countries of USA, Germany, Greece, Indonesia, Malaysia and Israel.
  • At most retail stations, three octane grade are offered, 87 (regular), 89 (mid-grade) and 91-94 (premium).
  • Hindustan Petroleum Corporation Ltd (HPCL) had recently launched Octane 99 and now IOC has come to the market with XP100.
