Octane number is an old-fashioned rating of petroleum fuels and aviation spirit.

Explanation:

Fuels with high octane numbers can withstand compression without detonating more than fuels with lower octane numbers. And thus high octane numbers are favoured for the internal combustion engine, but fuels with lower octane numbers, that can withstand compression, are used for diesel engines.

The fuel performance is a percentage according to #2,2,4-"trimethylpentane"#, which has an arbitrary #"100 octane rating."#
