Feb 21, 2024 · So, what is octane? It's a hydrocarbon molecule that gives gasoline the ability to resist detonating prematurely in the engine, which causes engine knocking or pinging during combustion. An octane rating measures the amount of the molecule that is in everyday gasoline. The higher the octane number, the greater the fuel's resistance to knocking.
An octane rating, or octane number, is a standard measure of a fuel's ability to withstand compression in an internal combustion engine without undergoing pre-ignition. The higher the octane number, the more compression the fuel can withstand before detonating.

Octane number, measure of the ability of a fuel to resist knocking when ignited in a mixture with air in the cylinder of an internal-combustion engine. The octane number is determined by comparing, under standard conditions, the knock intensity of the fuel with that of blends of two reference.
Summarize this article for a 10 year old. Octane is a hydrocarbon and an alkane with the chemical formula C 8 H 18, and the condensed structural formula CH 3 (CH 2) 6 CH 3. Octane has many structural isomers that differ by the location of branching in the carbon chain.
The octane rating of gasoline tells you how much the fuel can be compressed before it spontaneously ignites. When gas ignites by compression rather than because of the spark from the spark plug, it causes knocking in the engine.
