Octane Rating: A Comprehensive Guide to Its Legal Definition
Definition & meaning
The term "octane rating" refers to a measure of a fuel's ability to resist engine knocking or pinging during combustion. It is calculated by taking the average of two values: the research octane number (RON) and the motor octane number (MON). Specifically, the octane rating is determined by dividing the sum of these two numbers by two. This rating helps consumers understand the performance characteristics of different fuels and make informed choices for their vehicles.
