Octane

Octane is a hydrocarbon (a compound of hydrogen and carbon) with the chemical formula C₈H₁₈. It’s a component of gasoline (petrol) and other fuels.

Definition:

The octane rating indicates the fuel’s resistance to knocking or premature detonation in an engine. A higher octane rating means the fuel can handle more pressure before igniting. This makes the engine run smoother and more efficiently, especially in high-performance vehicles. Octane ratings are measured on a scale, with typical gasoline ranging from 87 to 93 in the United States. Higher octane fuels are used in high-compression engines, such as those in sports cars and luxury vehicles

Example Sentences:

• The high-performance engine requires premium gasoline with a high Octane rating.
• The mechanic recommended using higher Octane fuel to prevent engine knocking.
• The Octane booster increased the fuel’s resistance to pre-ignition.
• The racing fuel had an Octane rating well over 100 for maximum power.
• The study investigated the effects of different Octane levels on engine emissions.
