Home > Glossary > Octane


Octane is a term commonly associated with the energy industry, specifically in the context of fuel quality and performance. It refers to a hydrocarbon compound present in gasoline and other fuel types, derived primarily from crude oil. Octane rating is a critical measure used to evaluate the anti-knock properties of a fuel, indicating its ability to resist knocking or pinging in an internal combustion engine.

Commonly denoted as ROZ (Research Octane Number) or MON (Motor Octane Number), octane rating determines the fuel’s ability to withstand compression before igniting. The octane number represents the percentage of iso-octane (a reference fuel with excellent anti-knock properties) that must be blended with n-heptane (a reference fuel with poor anti-knock properties) to match the knocking behavior of the fuel being tested. The higher the octane rating, the greater the fuel’s resistance to knocking, and the more efficiently it can power an engine without experiencing pre-ignition or damage.
