Meaning
A measure of the antiknock properties of gasoline.
Classification
Nouns denoting quantities and units of measure.
Examples
- Higher-octane gasoline can be beneficial for vehicles that have high-performance engines because of its increased octane number.
- A higher octane number in gasoline generally results in less engine knocking and increased engine performance.
- To improve fuel efficiency, drivers may switch to a lower octane number in gasoline, as the energy released by lower-octane gasoline does not cause noticeable issues for average engines.
- Octane number of fuel used for passenger cars ranges from 87 to 93, as lower values might result in inefficient combustion in vehicles with standard engines.
- Vehicles using low-octane fuel, that have higher-octane-number-requirement, will typically exhibit issues with power and may make noise caused by fuel misfiring in their engine.
