Octane rating measures the combustion quality of petrol or gasoline. Higher the octane number, lesser is the tendency to knock during combustion. To determine the octane number, two fuels iso-octane and normal heptane are mixed in a certain proportion by volume. If the mixture contains 80% iso-octane and 20% normal heptane by volume then the petrol has octane number of 80.
“The octane number can be defined as percentage by volume of iso-octane in a mixture of iso-octane and normal heptane”
The actual octane number for petrol is about 96 for premium and 90 for normal.
